Lennox 53L59 Heat Exchanger

The Lennox 53L59 is a heat exchanger, which is an essential part of any gas furnaces and some gas-based heating and cooling appliances. This transfers heat from the burning process to air passing through the system and identifying the conditions when such transfer is optimum. Hot exhaust gases pass through internal tubes in the exchanger which in turn heats the metal wall of the tubes. After that cool air from the living space is passed over the exterior of the exchanger’s fins to absorb this heat. This efficient heat transfer warms the air, so you get comfortable heating for your home.
