Furnace (also Heater) - a part of the heating system in residential buildings, here occurs the combustion of fossil fuel such as natural gas for example and transfer of heat. Gas jets along a burner ignite to create the hot combustion gas that raises the temperature of air, which fans then circulate through the ducts. A natural gas furnace is a great way to heat your home. It provides quick, powerful heating at a relatively low cost per month. Almost every kind of furnaces burns fuel to create heat.
Four main types of furnaces

- Oil furnace
- Electric furnace
- Propane furnace
Electric furnaces can heat the air by exposing heated elements, while other types of furnaces typically require a heat exchanger or chamber that warms the surrounding air.
Furnaces remain the most popular choice for home heating due to their high efficiency, low operating noise, long lifespans, compatibility, and more.
