Overview Of Working Of Electric Furnace?

Now the question arises, How do electric furnaces work? Working and installing of electric furnace is easy. An electric furnace is similar to a gas furnace but requires electricity for work instead.

An electric furnace works with the assistance of a thermostat to detect temperature, whether it is below the fixed point. If the temperature is below the set point, the blower fan and the heating elements are turned on automatically. The blower starts blowing air onto the heating element, warming the air.

The electric furnace has about three to six heating elements. Each with converting capacity of about 3.5-7 kW of electricity to heat. The electric heater controls temperature with the operation of ducts over each room. After the air is warmed and the temperature is achieved the blower and the heating element automatically turn off.

A home heating electric furnace is highly efficient as it converts every electrical charge into heat. This operation is carried out through several components as defined below.

The Key Components Of An Electric Furnace

  • Heating element

The heating element of an electric furnace consists of long electric wires that are wounded into a coil inside the furnace. These wires are made of highly electrical-resistant metal. Mostly nickel and chromium are used for this purpose. When electrical charges pass through the wire, the resistance faced by the charges produces heat.

The heating element is further constructed of a few parts that include
