Available22 products
Whole-house gas furnaces connect to natural gas lines to produce heat for multifamily homes. They burn natural gas to heat their heat exchanger, which transfers heat to airflow passing over the exchanger and gets blown out through the homes' ductwork. These furnaces are used in new installations and to replace existing furnaces of similar BtuH output.
Annual Fuel Utilization Efficiency
Standard-Efficiency 80% AFUE Whole-House Gas Furnaces
Furnaces with an 80% Annual Fuel Utilization Efficiency (AFUE) rating turn up to 80% of their fuel into usable heat while losing 20% through the exhaust. They have a single heat exchanger. These furnaces are commonly used to heat multifamily homes.
