Commonly Asked Questions:

Q: Does the Hot Dawg® vent to the outside of the garage?
A: Yes, it is supplied with a factory-installed venting system that allows for either vertical venting through the roof or horizontal venting through a side wall. Venting components must be purchased separately and installation should be performed by a licensed contractor.

Q: What venting parts are needed?
A: Vent pipe, wall thimble, vent cap and flue adapter. Residential applications using heaters HD30-HD75 will also need to purchase a 3" to 4" increaser. See the table of Hot Dawg® venting components.

Q: What size gas connection does the Hot Dawg® have?
A: 1/2"

Q: How is the Hot Dawg® mounted in a garage?
A: Angled hanging brackets designed for 3/8" bolts, lag screws, or rods are included with 30,000-75,000 BTU models. This allows a snug-to-ceiling installation with 1" clearance, or the unit can be suspended with threaded rods. 100,000-125,000 BTU models do not include mounting brackets. These units can be mounted with 3/8" threaded rod or 3/8" eye bolts and chain.

Q: Can the unit be flipped to allow left-or-right hand access to the controls?
A: Yes, the 30,000-75,000 BTU units can be flipped. The 100,000-125,000 units cannot be flipped.

Q: Can the louvers be moved?
A: Yes, the louvers are fully adjustable to direct heat where it is needed.

Q: Is the Hot Dawg® Heater covered by a warranty?
A: Yes, the residential warranty is 2 years on materials and workmanship on all parts except the heat exchanger, which is ten years on materials and workmanship. Labor related to the installation and/or repair is not covered. See Manuals & Resources Tab for full warranty details.

Q: Can the Hot Dawg® operate at high altitudes?
A: Yes, a high altitude kit is required for elevations above 2,000 ft. Please specify your exact altitude in the box provided during checkout if you require this kit. This kit typically ships along with the heater. We will notify you if it will ship separately.

    Easy Install

    Review by Fred H on Apr 13, 2016

    Installed in a out building that is going to be my shop. I am running on Propane. The unit arrived with the propane conversion and high-altitude adjustment already installed. Started on the first try and appears to be running great. Arrived quickly and in great shape.

  • 4 Stars

    Product was good

    Review by Kurtis on Jan 21, 2016

    Product was very good and relatively easy to install. However, keep in mind this is a direct power vent and will blow exhaust with pressure that tends to leak through the vent pipe and gets recirculated with the fan. You need to make tight connections and use proper taping to make air tight. I also had to use heavy clamps to keep secured.

    Only other issue is that the unit arrived dented and damaged from delivery so make sure to verify any issues.

    Well made!, looks Great! and easy to use

    Review by BartSalyer on Jan 1, 2016

    Very simple install, straight forward for electrical, propane, and thermostat... Some of the instructions are a little confusing, but a call to the company and solved my questions. Unit is installed in a 24 X 50 10 foot tall ceiling without insulation at this time. Within an hour brought temp from 45 degrees to 65... Nice, Warm, and cozy... This was an easy install... Don't hesitate to make it happen... The only downside is the control board inside is not supported and moves around during install...

    It's either a lemon or junk

    Review by Lryan on Dec 30, 2015

    Bought our heater last spring but didn't get installed until this fall because we really didn't need it. It has been a problem ever since. We have a 2.5 car garage and bought the 75,000btu/propane. Had it professionally installed and it has had problems starting since installation. Now we have had it installed for a few months and it already need s a new motherboard!!!!! It's not even like we have used it all that much considering this has been the warmest fall/winter in 100 years. I am very disappointed. WHEN it does work, it heats up the garage like crazy....

    good service good product

    Review by Nick on Dec 29, 2015

    I got my 60,000 btu HOT DAWG installed and running the other day, so far so good. My installer was impressed with the construction and the size of the fan. Other than the flimsy mounting brackets he said the product was much better than the M_ _ X product. He liked the fact that it was made in the USA and not China. From my prospective my salesman Larry and the whole QC Supply team was great. They answered all my questions every time I called, and believe me I called many times before the purchase. After unpacking my heater there was a dent at the top of the case, I called QC Supply wanted to see some pictures of the unit and box, less than 12 hours latter they address and corrected the issue to my satisfaction. I would buy from these guys again..

    Great unit for the price.

    Review by Greensteam on Dec 22, 2015

    Took Propane Co. forever to come out and hook up the Hot Dawg 75K BTU. But it has been running for about 3 weeks now and works great. The guys working in the garage really appreciate it; don't have to run out and get kero to fire up the torpedo heater. We have a 26' 30' garage with 11' ceiling and it keeps it nice and toasty. Was a good investment, should have got it sooner.

    Very Reliable well built Shop Heater

    Review by tpackage on Dec 10, 2015

    Ordered this heater from QCSupply.com and I had it was delivered on my porch 2 business days later! Thanks QCSupply!

    The heater works perfect, puts out a lot of heat! My Shop is 24ft x 34ft and it keeps it at 70deg without much effort at all.

    I used a digital thermostat, and it works perfect with this heater. The plumber that connected up the 50ft of 1/2" gas line, said these Modine heaters are the absolute best, and he said it would probably outlast me. (I'm only 49 years old)

    I also purchased the Quick-Sling Flush mount, and it made mounting the heater to my ceiling, so much easier. (Although I did have a forklift here to raise it up to the ceiling, but if you are mounting it to the ceiling, it is well worth the extra $ to also get the quick-Sling Flush mount for it. Thanks again QCSupply, I am very satisfied!

    Great Heater

    Review by wyoguy on Nov 20, 2015

    When my combination controller/gas valve went south on my 10+ year old 45k Btu Modine, I found out the valve was over 60% the cost of a new heater. I ordered a new heater from QC Supply. Heater arrived (shipped free of charge) in less than a week. All documentation was complete along with instructions for setting up for high altitude (we live over 6,000 feet above seal level. As a bonus, I discovered the expensive Congo controller/fuel valve has been replaced with a individual control board and simple fuel valve---a definite improvement in the event something breaks in the future (control board is 1/4 the cost of the combine valve.)

    It's a Modine!

    Review by UtahJoe on Nov 20, 2015

    I installed the 75,000 in a 24 X 36 garage a week ago. I had the walls insulated but not the ceiling. Took 2 of us 4 1/2 hrs and that included running 70 feet of pipe. It heats this garage fine and quick. No need to go bigger in BTU. 2 of the louver springs had came out and were lost in the well packaged box. I went to the hardware store and got a couple that I made work. No biggie. Fired right up.
    My local HVAC guy wanted 2400$ to install a heater this size in my garage. I am in it about $980 with pipe and vent.

    Review by HG on Nov 5, 2015

    Arrived quickly with no damage. Easy to install following directions. Start up was quick with no problems. Have not had any cold weather as yet but after operating for 15 minutes on start up, it is obvious it will easily heat my 1280 sq. ft. workshop.

    Review by Andy on Oct 9, 2015

    Easy to order, great price, to my door in much less time then I expected, and packed like a pro on a shipping crate like I hoped it would be for something that is actually pretty fragile even though its mostly steel! I haven't installed yet, but if you are set on buying a modine then buy it from QC Supply!

    Second one I have owned

    Review by Buck on Oct 1, 2015

    I did lots of comparisons before I settled on my first Hot Dawg heater. I just purchased my second on for my barn. I love the reliability of these heaters. There easy to install and do the job. Shipping was outstanding. Unit arrived wrapped on a pallet. QC has the best price I have found and you can't beat free shipping.

    I haven't used the heater I recently purchased for my son's house but I have one in my garage and I think it is wonderful. My garage is 30 x 50 and the 75K heater makes it comfortable in minutes on the coldest of days. I recommend it highly and that is why I bought another one.

    Review by SteveL on Jul 10, 2015

    I can only comment right now on the service at this time since ive had not installed or ran this 45,000 btu furnace yet. We will have to wait for a product review since it is summer here in Chicago and i will probably not have this up and running until fall. However, service before during and after ordering were excellent! Shipping was quick and furnace appears to be in great shape. Will submit another review in winter, after running it.

    update for 'so far, so good'

    Review by Randy on Apr 21, 2015

    Although it works great, it's developed rattles and vibrations. I checked the sheet metal screw and found about 25% of them stripped from the factory. The fan cage on the back has 4 bolts and one of those was stripped as well. I had to add rubber between the cage and the unit and add larger sheet metal screws.
    It's now quiet thru the whole cycle. Its a good heater but the factory should have better quality control.

    so far, so good

    Review by Randy on Mar 30, 2015

    45,000 Hot Dawg install was ez. Finding a 3 inch to 7 inch adapter was tough, I vented thru existing double walled vertical stack from old 150,000 propane btu unit. This is in a 30 X 52 fully insulated man cave-12 foot ceiling. It never gets colder than 45 . Getting up to mid 60's takes about 30 minutes and uses a fraction of the LP. This unit should pay for itself in a few years. I can now hear myself when the heater is running. Should have done this years ago.

    Review by jas on Mar 3, 2015

    my unit was damaged in shipping, Qc was quick to make me a happy customer. i had a large 180000 modine unit in my shop that ate propane. i purchased the 75000 and if need be i will use a small torpedo heater ,the two will still burn a fraction of the gas. unlike the large one i removed this one has warm air not hot air coming,so if your looking for a blasting hot air heater this is not it.

    Review by MJP on Feb 6, 2015

    Very hppay with my 60,000BTU unit. Arrived in good shape and the unit itself is pretty easy to install...my one complaint is the instructions are pretty marginal, understanding they are trying to cover multiple models with one set of instructions, my be good for Modine but sucked for me...Please make the instructions more spacific to what is in the box!!

    Review by Mike on Feb 1, 2015

    Well, It's February now, and it's been COLD! This heater is OUTSTANDING! Keep it at 50 degrees and crank it up to 68 when I'm going to work in my garage, which is a lot this winter. Gas bill has not increased too much. I do have a very well insulated garage, with an R21 door. It was 11 degrees today and I was in there all day at a comfy 68 degrees. Didn't really run all that much. Easy install.
    Highly recommend!

    Good product overall.

    Review by miko on Jan 26, 2015

    I mistakenly expected the product to immediately expel hot air when it turned on. It doesn't, but after it heats up it recirculates and reheats the air over and over again. This process proceeds rather quickly, but don't mistakenly think that it is like an electric heater like I did. It is a quality product that does a good job. I like QC Supply as a first time customer, and the Modine Hot Dawg is a good solid product that does it's job.

    The Hot Dawg heater works excellent and the service was also excellent

  • 5 Stars


    Review by Bill on Jan 22, 2015

    Just installed my new Hot Dawg 125K heater in my 36x36 shop. Hardest part of the installation was just getting the unit up and secured into place. Finally figured out how to rig a chain fall up and lifted it into place easily then. Checked gas pressures, electrical connections, and vented it. Turned gas on, flipped the thermostat on and Click (flipping the toggle switch next to the thermostat) - whirrrrrr (purge fan inside heater) - another soft click (gas valve opening) - shusssh (ignition)- more whirrrr (big fan) and hot air fills the shop. It's ALIVE! I love it!
    I did have one problem when wiring the thermostat to the circuit board. I own probably 40 different screw drivers of all sizes, shapes, and descriptions. None of them would fit between the gas valve and the wiring connections on the circuit board. Finally had to remove the circuit board in order to get a screw driver in to tighten the wire connections for the thermostat. Not a big deal for me but Modine needs to take a look at this.
    This heater replaces an older Empire unit heater that has given me problems every since I bought the thing. Wish I had replaced it a long time ago.

    works great!

    Review by Catfish on Jan 17, 2015

    This is replacing a Mr. Heater in my garage. Mr. Heater has poor customer service and parts are hard to come by. After installing in my 2 1/2 car garage, I am very happy with the performance. Works great, and is quiet! (Mr. Heater was fairly noisy) The only suggestion I have for QC is to remove louvers and springs before shipping, as these were all over the place. Luckily I found all the springs (which hold the louvers in place)

    Good Heater

    Review by Drew on Jan 6, 2015

    Good small heater, but it is a little noiser than I hoped. The fan on the back was unbalanced, so I balanced that and it reduced the noise considerably and reinstalled the fan bolts with foam rubber washers. I also installed thick rubber foam in between the bracket and the ceiling and installed the bolts with thick rubber washers and fender washers. Overall pleased, but a real balanced fan blade would reduce all the vibration.

    Review by Rex on Dec 12, 2014

    This is the second 75,000 btu Hot Dawg that I have purchased. I have both installed in my 4000 sqft. shop. One was actually keeping it heated. But, I wanted to divide the shop in half with a curtain to reduce costs. Bottom line, the heater works great and is fairly economical to run.

    Ordered Fri. night, received it Wed. a.m. Replaced a 30 year old Dayton 100k shop unit with the 75k Modine. Great service at a lower price, and free freight, too. The only problem was going from a 6" vertical vent to a 3" horizontal vent. I had to change roof jack too. Runs great!

    so far seems like a good product

    Review by sledgehammer on Dec 6, 2014

    Got the best price from Q C no shipping costs or taxes. Delivered in reasonable time. Very well packaged but unit had a dent in the front. This had to have occurred at the factory before it was packaged for shipment since there was no way it could have happened after packaging. Also came without paperwork. I called Q C and spoke with a rep who was very courteous and sincere about my concerns. He sent me a copy of the necessary paperwork in the mail in just 2 days. I wasent too concerned about the dent since it didn't affect the operation of the unit, and wasn't noticeable once it was hung. I do believe the manufacturer should be a bit more conscious of quality control. The unit so far has worked beautifully and does the job I bought it for. QC was great to do business with and I would not hesitate to use them again .I would have gave a 5 star except for dent and no paperwork.

    Great powerful heater

    Review by Jdale on Nov 20, 2014

    Great heater! I bought the 75,000 BTU unit. Fit closely to ceiling for a nice clean install! I ran it this week in northern Indiana with high temperatures reaching 16-22 degrees Fahrenheit. It heated my 1096 sqft 3 car garage with ease. And that's even with no insulation in the ceiling and 3 large overhead doors on the windy side. Walls were insulated and ceiling is 10 ft high. (I ran out of time to finish insulating before a big project) but stayed ice and toasty! Great buy!

    good unit but not perfect.....

    Review by none on Nov 14, 2014

    The delivery of my new unit was on time, and undamaged so (so far so good). I hung the 30k/btu unit (LPGAS) from the garage ceiling with unistrut. The installation was easy except that the thermostat connections are in a location on the control board which is not easy to get to. Other than that the install was simple (I do this sort of thing routinely). The first fire up was ok, with the usual "hot" smell coming off from manufacturing oils, but the annoying thing is that when the fan comes on, it makes a vibrating sound. I may have to install isolation rubber washers on the bolts or something to quiet it down. Works great though in spite of the noise. Don't get me wrong, it isn't terribly noisy, but loud enough to be annoying unless you have other noise (road noise, etc. going on).

    Review by John on Sep 3, 2014

    Very quiet when running and puts out a lot of heated air. Very intuitive to install if you read all the instruction. Be prepared to lift and support 80lbs to seven feet off the floor to mount. That was the only difficult part for me; my 16 year old grandson came in handy. Overall, I'm very satisfied with this product.

(course we live next door to Nebraska, but i was impressed that while ordering on a weekend online, that i had conformation, and tracking numbers Monday b4 noon.) We re converting from elec. to natural and sure could've used these in the cottage and main house this past winter... it was cold in Wyoming this year. Anyway! Even our natural gas supplier was 350.00 MORE then QC. For the SMALL one! And, i was told they're loud. .. BULL! Ive heard normal house furnaces louder.. sooooo glad. Got these.

    Review by BuiltX4u-Ohio on Apr 1, 2014

    I bought this 75,000 BTU gas heater ten years ago.

    To this day it is still running flawlessly. Best investment I made to heat my 32'x40' shop. I have 12' ceilings and keep the temperature at 45-50 degrees when i'm not using it. Only takes half hour to get it up to 65-70 degrees when you need heat. Shop is fully insulated. I will always own one of these little heaters. Best anywhere. Cost me around $95.00 for a month to keep shop heated.

    Quality built in the USA

    Review by Jollygiant on Mar 23, 2014

    This unit replaced a 35 year old Modine 45,000 btu unit that the bolts holding the motor broke off. I repair the motor bolts and finished the season, but I thought I would update to a newer unit. I was pleasantly surprised to see that QC Supply carried Modine heaters and that their prices were the best around. I like the fact that this unit can be mounted close to the ceiling, unlike my old heater that was suspended with rod. Installation went easy and the quality is USA at its best. It heats my 2 1/2 car garage nicely and quickly. I gave my old heater to my son-in-law and suspect that he will get years of good use with it. Go Modine!

    Very efficient - easy to install

    Review by T-Montana on Mar 20, 2014

    I installed the 75000 btu unit last November in a 900 sq ft garage with 12' ceilings. Easy to hang and used 3' of B vent horizontal out the wall. Venting cost $50.00. I set the thermostat at 40 degrees in November and after a cold winter I can report it always kept the garage at 40 and it only cost about $50 in natural gas, use based on affect on my power bills. I don't spend time in the garage so I only once ran the heat up to 60 degrees. It did that on a cold day in about an hour. So gas costs, of course, would be low.

    I am very pleased with the heater and believe it is a superior choice over other brands. Pending long term reliability, I believe it is worth the cost.

    Exactly what I needed.

    Review by Greywolfe on Mar 7, 2014

    This is exactly what I needed to heat my Future Steel 25' x 50' ( building. I mounted it on a 6' pedestal made from slotted steel angle iron anchored to the floor. I only needed the assistanceof two others to lift it inplace. The propane and electricity were very easy to connect as well as a simple digital thermostat. I turned it on and it worked right the first (i.e. I didn't make any mistakes). I is fairly quiet when running and it raised the temperature from 60 deg. to 72 deg. in about 15 minutes.
    It will be kept at 40 deg. when we aren't using the building for people things. I can now store things I don't want freezing over the winter (got to -10 deg. in December). We have Thanksgiving and Yule potlucks in there and raising it to 68-70 deg. will be a snap.
    I am very happy with this heater and recommend it for a similar space or a smaller unit for a smaller space.

    Great Heat

    Review by Bucky G on Mar 7, 2014

    Just got the 75K nat. gas Hot Dawg up and running yesterday in my 42x23x10 ft. insulated garage yesterday, they had the best price anywhere. Delivery was prompt and courteous. As background my dad put a 30k unit in his new garage 20 years ago. It still runs like a champ, so when I finally got tired of this never ending winter I wanted a Hot Dawg too. This unit really puts out the heat and is actually quieter than the 30k due to the larger diameter fan. The only thing I didn't like is the brackets included for hanging the heater. The 75k heater is too heavy to rely on 6 sheet metal screws to hold up its 87 lb. of weight. When I got it mounted I noticed the brackets were tipping and pulling on the screws. I used steel strap around the heavy end to support it. Not pretty, but much safer.

    Very Positive

    Review by Dan on Feb 20, 2014

    I purchased the Hot Dawg 75,000 BTU at QC Supply because it was the best price for the unit on line. Before I purchased I had my local propane company come to the house ant look at my garage. Although they use a different unit they have in the past used Hot Dawg and gave it a very positive review. They could have ordered one for me but told me to buy it from QC because they couldn't match the price.

    They estimated it would take two guys eight hours to install. It took about 5.5 hours and it was up and running. When I first turned it on the garage temp was 29 degrees. In about 20 minutes it was 60 degrees. The garage is 35' x 40' with sheet rock and 4" of insulation in the walls and ceiling.

    The unit is very quit compared to my old method of heating which was a 50,000 btu propane salamander which was also very dangerous as the fumes didn't vent to the outside and the smell was terrible. I couldn't be happier.

    Modine Hot Dawg 45,000 BTU Garage Heater

    Review by Coloradotrailrider on Feb 8, 2014

    I have had this 45,000 btu Hot Dawg installed for about a month now in my garage here in Brighton Colorado. I have to say this heater works extremely well in my fully insulated 600 sq ft garage.

    We have just had the coldest weather for the season, -17 degrees F at night sometimes, and this heater has performed flawlessly. I was in the garage one day and had the thermostat set for 70 degrees, it was 5 degrees outside, and the Hot Dawg had no problem getting it to 70, could have easily gone higher.

    When the heater is sized properly for you application you will love it.

    The heater showed up very quick and packaged nicely. Although the ad may be misleading it states that it comes with venting, but it does not, rather it is just stating it is a vented heater. Also there is no real way of hanging it either. No ready rod or anything. My suggestion is order the vent kit and any of the hanging setups shown in accessories.

    Hung a 45,000 BTU in a small 2 car garage 400 square ft garage and heated garage to 72 degrees in less than 30 minutes. 12 degrees outside temp. This is a attached garage with only one exterior brick wall and an insulated 2car garage door. To maintain 70 degrees the unit ran for 10 minutes, rested for 22 minutes and repeated similar pattern making up about 20 minutes per hour of actual run time. Holding the room temp down to 65 would require it to run even less. Heat recovery time was remarkable when I experimented opening the garage door to let the frigid cold air in. Mine is 2 weeks old and I am more than pleased. Wife loves it. Makes going through the garage to let the dog out back nice at night pleasant.

    Great Product and Service from QC

    Review by Headsavage on Dec 15, 2013

    I reviewed many heaters before purchasing this 100k Hot Dawg unit. I try to buy Made in the USA first and this buy did not disappoint me one bit. I'm heating a 1400+ sqft garage with an average temp kept at 50. I live in Colorado so a high altitude LP kit was required which came with the unit and price. I purchased a permit and setup myself over a few weeks. My 250gal LP tank was installed, Inspected so I'm off and running.

    QC offered a great price plus they knocked off another 5% with free shipping. How can you beat that. Located in my neighboring state the unit was top notch packed, delivered pronto and unharmed. I would not hesitate future buys from QC Supply.

    Somethings you can purchase overseas manufactured items that you won't use everyday but for daily use we need to buy quality and this is one of them. Great product.

    Could have had better quality control

    Review by Wayword on Nov 15, 2013

    This unit arrived quickly and in good condition after shipping.
    The unit did have a problem, though. The control transformer mounting plate was not secured adequately and was hanging loosely in the cabinet. I drilled another mounting hole, since none seemed to be available and installed a sheet metal screw. The wiring also was not adequately secured and interfered with the combustion blower.
    Installation was relatively simple, but not exactly easy. Installing a double walled vent the way the instructions called for took a bit of work and routing through the ceiling.
    I have a three car garage that this heats and have noticed that it doesn't run very long between cycles with out door temperature at 20 degrees. Seems to be a bit much heat output for this amount of floor space even with 9 foot ceilings. The ceiling is insulated with 4" and the three garage doors are insulated as well.
    While it says this is quiet, it is not really. Not a jet engine, but you do hear the combustion blower in the laundry room next to the garage - through the wall.

    I bought 2 of the 75,000 BTU hot dawg heaters for my 1600 Sq. Ft. garage with 15 foot ceilings in the cold state of Maine. They arrived in perfect condition and when promised. The only problem I had was the small sheet metal screws that hold the mounts, I didn't want almost 90 lbs. hanging from 6 little screws. I drilled them out and installed #12 sheet metal bolts. If you are going to use stainless flue pipe purchase it from C Q, their price is almost 1/3 less than what I paid up here. Heat fast and fairly quiet operation.

    I could not ask for a better heating unit. I installed two of the 75,000 BTU units in my 1600 Sq. Ft. shop with 15 Ft. ceilings. With my two 60 inch ceiling fans the shop is nice and warm. I live in central Maine and the weather gets really cold at times (about 48 weeks a year). No hassle ordering, shipping and delivery from Q-C Supply. Only thing I did not like was the angle iron mounting screws, they use the same screws that hold the sheet metal cover to the unit (Very small) so I re-drilled the holes and used #12 sheet metal screws. My HAVC guy said it was an overkill but that's the way I always do stuff.

    Good heater

    Review by Daryll on May 2, 2013

    Purchased the 75K BTU propane model. Easy to install, mounted it to ceiling joists in my work barn. Hook up a propane line, a 120VAC power line, a 2-wire thermostat, and the exhaust, and you're good to go. Using B-vent for the exhaust makes things a lot easier, just measure, get your components, drill a hole, and piece it together. I have about $80 in B-vent components for a roof exhaust (two 18" and one 36" pipes, a T and a T cap, flashing, storm collar, top cap, and a support bracket).

    The unit runs quieter than others I've seen in operation, and throws heat as far as the specs said (38'). My only apprehension was the included mounting brackets are held onto the unit with just six 3/4" metal screws. I added one more on each side for a total of 8, and its very solid, but I'd be a little more comfortable with more substantial bracket mounting hardware.

    If the unit continues to perform well, it has earned the 5-star rating I gave.

    Review by Ted R on Apr 29, 2013

    Originally installed a used 80,000 BTU heating unit that was way oversized for my 800 SF insulated, 4-car garage/shop in Northern Nevada. Tired of replacing the thermocouple and ordered a replacement 30,000 BTU unit. The New Modine unit is very compact and fits very well. Well constructed, pretty quiet and works very well. Proper sizing makes a big difference in operation. Heating bill dropped dramatically. Very pleased with QC Supply in both communication, lightening fast shipping and product as described. Highly recommend QC Supply and Modine products for your next purchase. If you are treated as well as I, you won't be disappointed.

    I installed the Hot Dawg 45 on the ceiling of my two-car garage. I used the mounting brackets that came with the unit and they worked as described. The brackets provided the minimum 1" clearance to the ceiling.

    My garage is not insulated and the temperature outside is around 25 degrees. The heater was able to heat the garage in about 15 minutes up to 65 degrees and was able to maintain that temperature without continuously running. I would recommend this product for a garage/shop application.

    Review by Koko15 on Dec 23, 2012

    This review is for our Modine Hot Dawg heater, Model HD-60 (60,000 btu) burning natural gas. After some research, including a heat-loss analysis to determine appropriate sizing, we found the best price from QC Supply. Fast standard shipping via FedEx Ground was included in the price. The unit came fully assembled and ready to go to work right out of the box. Overall design, workmanship, fit and finish is excellent. We're heating a new construction 2 1/2 car garage and workshop area (28' x 28') with 11' ceiling and a heated living space above here in the chilly hills of Western New England. It was below freezing yesterday with the wind gusting over 40 mph but my garage stayed warm and toasty with the heater cycling only a few times an hour. Straightforward installation and very quiet operation.

    Clear, concise instructions provided by Modine, downloadable from QC website if you want to plan ahead. To complete the installation you flip the mounting brackets over from the shipping position and provide your own threaded rod and other hardware to mount to ceiling. You must also provide vent pipe, gas piping and electrical to comply with local code. I'm an experienced DIY'er and my buddy is a top notch plumber who has installed many Hot Dawgs. It was out of the box, mounted to the ceiling, gas piped and vented in about two hours. 30 minutes more for electrical, only because I took the time to run EMT conduit for a nice, clean installation. It fired right up with no problems. There was only a slight "hot metal" smell for about 10 minutes during the initial run-in, as should be expected from any new heater. It is now running beautifully (and quietly) on a Honeywell programmable thermostat, although any standard basic thermostat will do. The HD-60 draws 2.5 amps so you can comfortably run either 12 or 14 ga wiring for line voltage. Thermostat wire is standard 2 conductor (only red & white terminals are used).

    All in all, this is a very nice heater doing exactly what it was designed to do. This was our first purchase from QC Supply and we will definitely buy again. They have a very easy us use website, excellent product selection, logical check-out process and great communications from purchase to delivery. Highly recommended.

    Review by BMW 64 on Dec 22, 2012

    Just purchased and installed the Modine Hot Dawg 45 BTU Heater for a 16' x 30' Barn/ATV Shop located here in Western New York. Being way out in the 'sticks' and hills smack in the middle of 'lake effect' snow region, winters here can be quite brutal with very cold temps and winds!

    My shop is an ongoing restoration project started this past Spring of an old barn built way back in the 30's that really needed some major work. Along with new cement floor, re-framing of walls, insulation, siding, 9 windows and just a whole bunch of other stuff along the way ... a decent, efficient propane heating system was tops on the 'to do' list come cold weather. After advice of local HVAC outfits and looking at all the various makes, models of gas heaters ... everything pointed to the Modine Hot Dawg! The high efficiency, quality construction of the unit, along with the great price and superb service of QC Supply made the choice an easy one! After determining what size was best overall for my application, ordering on line was very simple and unit arrived safe, sound and packed very nicely in less than a week.

    Originally was going to go with the 60K unit ... but after considering BTU/fuel use/cost and that building is well insulated with 3.5" fiber glass in walls and foil faced foam higher up and in ceiling, I went with the 45K unit. QC Supply was very helpful in answering all installation questions, gas/electrical hook-ups and such. Considered using one the Quick-Sling Rafter Mount systems they offer ... but, after measuring and scoping everything out - I mounted unit flush to a pair of 2'x6' boards built within the overhead beams for a very secure installation. Unit is also positioned near the middle of the back wall at about 8 foot height as opposed to a higher location in the corner. Reason for this was *Easier mounting to rafter/beams *Ease of servicing and maintenance *Lower, more centralized heat discharge.

    Am in the process now of installing wall mounted hard pipe gas line and getting electric over to unit. So Far So Good, and the Hot Dawg looks great hanging there!! Can't wait to get the thing cranking out some heat and actually able to work out there during the winter months without seeing your breath!

    Review by Ron on Dec 12, 2012

    I live in Sandpoint, Idaho (winters 10 to 30 degrees). Heating a divided, insulated, pole barn 36' x 60' x 12' high. My first heater is the 75,000btu (it "throws" the heat 40ft.) the second one is the 45,000btu (it "throws" the heat 30ft.). Keeping the barn divided with a wall and large roll-up door really helps keep the heating cost down. If you are not sure what size heater to get, check out Modine's Hot Dawg web-site and you can determine the btu's you need by seeing how far it "throws" the heat. Great, reliable heater, have been using them for 8 years.

    Review by Gene on Dec 11, 2012

    My new heater came the other day. I installed it with the instructions given and all went very well. I had to call QC when I ordered it and a heart beat picked up the other line and directed me to a tech to answered my order and need questions. It made my decision and ordering process go real well. The service and politeness help out for the DIY guys. The unit is now rockin and I'm happy with it and with QC. It made me look around at what else they sell.

    Modine Hot Dawg 45

    Review by Joe I did it myself on Oct 27, 2012

    Well I bought this unit to replace an old house unit that had been in my garage when we moved in 11 years ago. Time to clear some floor space. Unit installed easily and fired right up. It is not that cold yet but it pushes out some heat so I am sure it will do the job. Great Unit great price.. Two of my neighbors know I research most everything I buy. They told me I was the guinea pig, if it works well for me you might just sell a few more to my neighbors.

    Great Heater

    Review by jstalt on Oct 26, 2012

    Bought the 75,000 btu propane unit in 2003. I keep my 3 car garage in NJ @ about 37-38 degrees when I am not out there just to keep above freezing mark. Takes about 45 min or so to warm up to 60 degrees when its 20 out. Not too bad. Never had a problem yet (knock on wood)!!! Very happy with heater.

    Good product

    Review by Jim on Oct 25, 2012

    So far so good. Installed the heater last week with a friend and it was easy to setup. I hooked up a thermostat and finally used it this morning in Colorado as it was 29 degrees outside. QC Supply delivered everything as quoted and no problems with the order. I will purchase products from QC in the future. Cheers, Jim

    Hot Dawn HD 60 k - perfect 3 car garage heater

    Review by Papa Edy on Mar 17, 2012

    I purchased this heater for a 3 1/2 car, short side attached garage 750 SF, 4" Insulation on ceiling , and 1" foam board on the walls with brick. 3 insulated doors. Normally it get down to 40 degrees in the winter. I did plenty of research and picked this unit. I am very happy. I keep 2 cars in the garge and lots of tools. I wanted a heater that would slowly rise the temp continously without cooking me when I am in front of the heater. I also didn't want the on off cyles that causes you to be hot-cold-hot-cold untill it reaches the temp setting on the thermostat. This heater is perfect. Runs about an hour to rise the temp 20 degrees. than it's off, and the temp holds for quite a while. The slow ris in temp also lets the car 's temp rise in sync with the air. The only problem is my wife is not happy that I'm now working in the garage in the winter with flip flops and a t-shirt on. I love it!

    Review by hammerhead on Feb 24, 2012

    I received this unit a few weeks ago. It came in with a bent side, but QC and Modine quickly shipped out a replacement side. It installed easily and the thermostat (Johnson Controls) worked good with the unit. I seems to heat well and I think it will be very cost effective. The unit is very quite and appears well made.

    Great garage furnace

    Review by NESD on Feb 18, 2012

    This is my 2nd Modine Hot Dawg heater in my garage. I believe the gas valve went bad in my other and since it was 10 yr.s old, I decided to replace the whole heater. While you should have 2 people to install this in the ceiling, it is small enough that I was able to accomplish it by myself. Since the gas line and vent system were already there, it was an easy install with just a quick trip to Menards for the right length gas pipe to go to the gas valve. The heater works great in my 3 stall garage in northern SD where winters can be quite cold. It takes about 20 min.s to heat it from 45 degrees (where I keep it for winter) up to about 55-60 degrees if I'm going to work out there. Very nice heater for the price.

    Hot Dawg Heating

    Review by Rudy on Jan 7, 2012

    Best price on the net and quick free shipping. Once you find the installation manual (inside the unit), directions are clear and easy to follow. 75K BTU seems plenty for my shop/garage that's about 950 SF. Quiet, reliable, and fast.

    Review by Mark on Dec 29, 2011

    The Customer service was great, they even called before it shipped and told us I could save some money on shipping by doing a couple of things differently. The only issue I had was the installation and owners manual were not shipped. I was able to download them online so it was really not a problem. I would recommend QC supply to anyone.

    QC Response: Manual can be found inside lower panel of heater.

    HD60 Hot Dawg Heater

    Review by Tom on Nov 18, 2011

    This is my second Hot Dawg Heater for my garage. Instead of converting my older unit which was propane, I purchased a natural gas unit. I could not be happier with QC Supply. Their price for the unit was the lowest. Period. And to get free shipping , you cannot go wrong. Plus, to have it delivered 2 days after I ordered it, that is just amazing. Their customer service emailed me when the order was processed and i was able to track it during transit. You cannot go wrong with QC supply. As for the heater it is the best around. Several of my friends have one in their garage and all love it An EXCELLENT heater over all and a EXCELLENT company selling them. A++++++

    Maybe too much heater

    Review by Creeker on Oct 12, 2011

    The price was the best on the internet. The shipping was fast.
    Installed it over 2 weekend after many trips to the hardware store for fitting, pipe, vents, etc.

    It works great but it's not as quiet as I had hoped. It's not loud, just a lot of fan noise and I need to turn up my music when it's running.

    I got the 45,000 BTU model and it may be too much heater for my 1 1/2 car garage in Santa Cruz but it may be perfect when the temperature drops to 40 and the rain picks up.

    A Heating Gem

    Review by Grinning Picker on Oct 6, 2011

    A neighbor of mine had moved from Wisconsin to the north Georgia mountains. He had re-installed a Hot Dawg he had used up north and explained that it had operated flawlessly for six years. After that testimonial, I ordered a 45,000 BTU for my two car drive under garage. QC delivered promptly and the installation was relatively easy. Works as advertised and QC was a pleasure to deal with.

    Review by Bobber on Feb 19, 2011

    The unit is compact and easy to install. I was replacing a Reznor unit and this is more efficient, easier and safer to operate and will hold itself together better than the unit we had. It is perfectly adequate to heat our 28 x 28 winery.

    125btu Hot Dawg

    Review by fowlplay on Jan 19, 2011

    Ive owned the 125,000 btu Hot Dawg now for 2 winters. It has performed flawlessly. It heats my 30x50 pole barn from 35-60 in 20 minutes (10' ceiling, well insulated). I probally could have got away with a smaller model, 100 or 75 btu model, but I wanted quick heat instead of steady constant heat..(I do not heat the barn full time and didnt want to wait a hour or 2 to get it up to temp). Awesome heater!

    Its a big heater for a 1200 sq.ft, insulated shop. Heats things up to about 65 in about 20 mins at 35 OAT. Fine for me as I use the shop for in and out stuff but a smaller version may be better economically and cycle wise for constant use. A bit noisy. As advertised-great shipping, price and product. 2 years now and going strong.

    Modine Hot Dawg Is Great!

    Review by Heater Guy on Feb 10, 2010

    I work as a professional in the HVAC/R industry. I have worked on industrial chillers to residential units. This Modine Hot Dawg is what I decided to put in the garage,and I am very pleased. I had it installed and running within 3 hours with the help from my father. It really is a great little heater, thats efficient, easy to install, and works great. It's very compact and simple, and really a great design. I have had it running for approx 25 hrs and burned about 20 gallons of propane.

    Review by Trail Twister on Jan 27, 2010

    I built a shelf in corner of garage up high so I could set the unit on and work on it myself. I noticed a wire hanging loose upon inspection and figured it had to go to igniter. (probably shipping problem) On startup It would not fire up and it was hard to read the label on what the problem was on inside of unit because it was upside down. ( Modine should have this label in owners manual.) I tracked it down to a pinched (bent) hose for the air switch. After that the unit works great and is a quality piece of equipment.Would definently recommend anybody to buy this unit.

    Couldn't find installation instructions at first. Thought they were not packed in the box. After some fustration found them INSIDE the unit. If that's where you normally put them have a label on the outside of the unit telling that is where installation an waranty are.

I ordered this on line on a Saturday and by Tuesday it was at my house with no damage at all.Not only am I glad that I bought this, I have told alot of my friends about these heaters as well. I do have a neighbor/ friend that also bought one this last week, only to find out that he has had some problems with his order. It took longer for him to recieve it and when he did there were some problems.

    Review by Phillip on Oct 23, 2009

    I purchased a Mr. Heater . Returned it for a Modine Hot Dawg. It is unbelievable the difference in quality. Stainless steel tube heat exchanger verses stamped spot welded sheet metal, thicker gauge sheet metal chassis, die-cast combustion blower housing verses sheet metal, higher quality fan blades and motor on main blower. This unit will out last Mr. Heater 2 to 1. Well worth the additional cost.

    Overall, this is a great heater. It keeps the shop warm, and does not seem to be overly expensive to run. It was quite difficult to install, as the venting instructions were confusing (and my ceiling, being high and slanted made for a tough one-man installation). They very helpful in getting me the correct conversion kit for 8500 ft. elevation and that was a breeze.

    A Hot Dawg for a cold state!

    Review by John the do-it-yourselfer on Jun 10, 2009

    I purchased a Modine Hot Dawg 75 and once the proper unit was installed it's become the envy of the neighborhood and my family's new best friend.Even during the summer being able to switch the thermostat to Fan mode the fan in the Hot Dawg puts out enough air to be felt over the entire 3 car garage and it does a great job of keeping my garage warm in the winter.I usually run the theromostat at 40 degress since the temp here in MN often drop down to -10-40 (not windchill actual temp! brrrrr) so when outside it's -20 and the garage is 40 and the house is 68 it's quiet a nice step up in comfort and if I'm working in the garage I have got the entire garage up to 70 above in minutes.To properly meet code you either have to use real large single wall vent pipe with a drain tube or just spend for the ALG24C grade pipe which is expensive ($200 for 5 feet) but works great and then you can run standard 3" or 4" diameter depending on the size of your Dawg.I love my Hot Dawg!
