In the early years, heating systems in most homes were basically furnaces. The introduction of new HVAC systems have made life easier and safer for premises. Older furnace models used wood and coal as fuel while the newer models use propane, gas, or electricity. Some can run high-efficiency levels of up to 98%, meaning that they convert this percentage of fuel into heat. So how exactly do they work?

Basic Mechanics

All furnaces use the basic principle of forcing air to heat up. Heat is transferred by the furnace into the air. The blower fans send the heated air through your house’s duct and out through the vents. The duct systems in the house are shared by both the air conditioning and furnace heating systems. This means you do not need to take up extra space for your home’s cooling system.

Propane and Natural Gas Furnace

In this type of furnace, a series of burners are ignited by a pilot light located inside the combustion chamber. The burners create heat which is then moved to the heat exchanger. The heat is transferred to the air and increases to the levels set by the thermostat. Once the thermostat temperatures are reached, the air is taken to the ducts by the blower.

Electric Furnace

The heating process is ignited by an electrical ignition. There are no gas powered burners, but instead heating elements that have conductive coils and which are heated when the ignition is initiated. Electric current passes through the coils which heat up to the set thermostat temperatures. The heated air is transferred by the blowers. The higher the set temperature required, the more the coils heat.
