Green Heating

Did you Know that:

If your family could use only renewable energy for all your energy needs, you could help reduce the amount of emissions in the air each year by 20,000 pounds of carbon dioxide, 70 pounds of sulfur dioxide and 50 pounds of nitrogen oxide

Efficiency of Infrared Heaters

An infrared heater is a body with a higher temperature which transfers energy to a body with a lower temperature through electromagnetic radiation. Depending on the temperature of the emitting body, the wavelength of the infrared radiation differs. No contact or medium between the two bodies is needed for the energy transfer.


There are two basic types of infrared radiant heaters.

Radiant tube gas-fired heaters used for industrial and commercial building space heating use combustion of a fuel gas such as natural gas or propane to heat a steel or ceramic tube. Radiant energy from the tube strikes floors and other objects in the area, warming them.

The advantage of this form of heating is maintained warmth even when a large volume of cold air is suddenly introduced. The infrared heating elements also conduct heat to the surrounding air, which can be lost heat if no mechanism exists for redirecting warmed air down to the floor level.

Gas-fired radiant heaters are sometimes used outdoors to improve the comfort of people at outdoor events or on patios.

Electrically-heated infrared heaters radiate up to 86% of their input as radiant energy. For practical applications, the efficiency of the infrared heater depends on matching the emitted wavelength and the absorption spectrum of the material to be heated.

Infrared heaters are used in industrial manufacturing processes including curing of coatings,  heating of plastic prior to forming, plastic welding, processing glass and cooking and browning food.

They are used when high temperatures are required, fast responses or temperature gradients are needed or products need to be heated in certain areas in a targeted way. Another recent use is in house heating, where claimed benefits include better circulation.
