Description
The Nordyne 904791 is a heat exchanger used in gas furnaces and boilers. It transfers the heat of combustion to the medium, which will carry the heat through it-usually air or water. Heat exchanger normally metallic construction such as aluminum or steel, may be used and suitably designed to handle high temperatures and corrosive conditions. The combustion gases travel through the heat exchanger, transferring the heat across to the other side where the heating medium goes through. It thus warms up either the air or the water that is circulated throughout the house or building to generate warmth.
