Our air to water heat exchangers can be used for Residential Heating, Apartment Buildings and Condominiums, Hybrid Systems,Air Conditioning,Dehumidification purposes.

water to air heat exchangers are used to transfer water heat in you forced air ductwork. water to air heatexchangers take hot water through a series of copper coils and alluminum fins. Your furnace fan blows through this water to air heat exchanger and super heats the air in you duct work then heats your home. While using a water to air heat exchanger it is most important that the nipple on the water to air heat exchanger that is closest to the fan is the cold water return to the outdoor wood furnace. The top nipple farthest away from the fan needs to be the hot water feed.

This is improtant because as the cool air enters the air if hooked up this way then the bottom nipple will pre heat the air entering the water to air heat exchanger and as it exits the water to air heat exchanger the top nipple will super heat the air.

If this is hooked up backwards the air entering the water to air heat exchanger will super heat the air and when it exits the water to air heat exchanger it will cool the air down.

we hope this helps with you installation of your water to air heat exchanger.
