Anyone sitting in the sun knows that the sun gives extra heat and an extra comfortable feeling although the temperature may not be high enough. Every time a cloud passes in front of the sun we are reminded of this. For animals sitting under a Gasolec Infrared Gas Heater is like sitting under the sun, as close to nature as heating can be.

In practice all heating systems use all three principles of transferring the heat but there are big differences in the ratios between these three variables between the systems.
