The efficiency of a heating system is typically measured by its AFUE (Annual Fuel
Utilization Efficiency) rating. Higher AFUE ratings indicate a more efficient furnace. Environmental impacts are a concern with heating systems, especially those that burn fossil fuels. The use of sustainable energy

48:: These systems generate heat in the space they are to heat, without extensive duct systems. Examples include electric space heaters, fireplaces, and solar heating.
1556:
42:: These systems produce heat in one central location and distribute it throughout the building. This category includes furnaces, boilers, and heat pumps.
1049:
298:
54:: They can be used for heating and cooling, transferring heat using refrigerant and electricity, making them more efficient than other heating systems.
