Solar air heater Solar air heating systems are supplemental heating systems that work in conjunction with, but independently of, your main heating system. The more hot air produced by the solar air heater, the less your primary heating system has to work -- and therefore the less fuel you have to buy. Solar air heating systems are different from most traditional heating systems in that the heating fuel is entirely free. You pay for fuel for as long as you use your boiler, stove, furnace, heat pump, etc.. With a solar air heating system, your initial (and only) investment is the air heater.. That's it. Your fuel-- sunshine-- is free. We carry recirculating solar air heaters. This type of system circulates indoor air through a sealed, electricity-heated copper pipe whichi is in the solar air heater and mounted on an exterior wall, returning the warmed air back to the living space. We use high efficiency solar panel to produce electricity ,and the cooper pipe will be heated when the air come through the pipe ,then the hot air is returned to the room ,this is our special design and has got the patent in China. For order with quantity of 100 sets or more, we supply with customized size service.You can choose size from the range: Width: 300-1200mm Length:300-3000mm For more information please contact us.
