What is an Electric Furnace?

An electric furnace is a heating system that relies on electricity to produce warmth. This system consists of a sizable unit placed centrally within a house or building, connected to a network of ducts and vents to disperse the heated air throughout the area.

The furnace typically contains a heating element, a blower to move the air, and various controls and sensors to manage the temperature and maintain safe operation.

Electric furnaces are renowned for their efficiency and dependability, making them a favored option for heating in both residential and commercial settings.

Electric Furnace Parts

The main components of an electric furnace include

Heating Element: This part generates heat, typically composed of resistive wire that warms up when electricity flows through it.

Blower: Responsible for circulating heated air within the building, usually comprising a fan and a motor.

Thermostat: Regulates the building’s temperature by controlling the electrical current to the heating element.

Control Board: Manages the furnace’s operation, often including various sensors and switches to monitor and control its functions.

Ducts and Vents: Distribute the heated air throughout the structure.

Air Filter: Filters the air passing through the furnace.

Limit Switch: A safety feature that monitors the furnace’s internal temperature and shuts it down if it overheats.

Relays and Contactors: Control the activation of the heating element and blower as needed.

Note: Specific components and configurations can vary depending on the model of the electric furnace.

Working on Electric Furnace

An electric furnace operates by transforming electricity into heat to warm a building. The process involves the following steps:

  1. The thermostat detects the building’s temperature and signals the control board to initiate heating.
  2. The control board sends an electrical current to the heating element, which produces heat through resistance heating.
  3. The blower, driven by an electric motor, distributes the heated air throughout the building via a network of ducts and vents.
  4. The air filter cleanses the air of contaminants before circulation.
  5. As the building heats up, the thermostat signals the control board to reduce the current to the heating element.
  6. The limit switch keeps track of the furnace’s internal temperature and will shut it down if it gets too hot.
  7. Once the desired temperature is reached, the thermostat signals the control board to turn off the heating element and blower, stopping the furnace until further heating is needed.

In summary, an electric furnace converts electrical energy into heat, distributing it throughout the building with a blower and duct system, and maintaining the desired temperature with the help of a thermostat and control board.

BTU and KW: BTU (British Thermal Unit) and KW (Kilowatt) are units used to measure an electric furnace’s heat capacity over a set period, such as an hour or a minute. A higher BTU or KW rating indicates a faster, more powerful heating capacity. Most electric furnaces range from 15,000 to 60,000 BTU or 5 to 29 KW. Some models express heating capacity in KW, with 1 KW equating to 3,142 BTU. Generally, for effective heating in moderate climates, each square foot of space requires 25 to 45 BTU. Larger rooms need furnaces with higher BTU or KW ratings.

Room Size and Furnace Selection:

  • 1,000 – 1,200 sq. ft.: 36,000 – 72,000 BTU or 5 – 15 KW
  • 1,500 sq. ft.: 45,000 – 90,000 BTU or 10 – 30 KW
  • 1,800 sq. ft.: 54,000 – 108,000 BTU or 10 – 40 KW

Range: Besides BTU rating, it’s important to check the furnace’s range. A furnace with a range smaller than your room size won’t heat efficiently, while one with a higher range will heat the room quickly but may shut off frequently.

Energy Rating or SEER: SEER (Seasonal Energy Efficiency Ratio) measures the energy efficiency of the furnace over a season. A higher SEER rating means the furnace uses less energy for heating. Look for models with a SEER rating above 16; many range from 17-20, with advanced models reaching 21-23.

HSPF: HSPF (Heating Seasonal Performance Factor) indicates the heating efficiency of the furnace. A higher HSPF rating means better heating performance, even in freezing temperatures. The ideal range is 8-10 HSPF.

Additional Factors: Consider other aspects like furnace features, size, dimensions, and warranty to find the best model within your budget. This article provides detailed information on top electric furnace models, their features, and a buying guide and FAQ section for further assistance.
