While electric radiators can sometimes have 100 per cent energy efficiency, only about 45 per cent of the fuel is burnt to generate the electricity. Therefore, these electric appliances are not as energy efficient as fossil fuel-powered radiators. The efficiency of electric radiators is determined both by the radiator's ability not to waste electricity and its ability to effectively heat objects and rooms. Objects and rooms that are not effectively heated by radiators require more heat, causing more electricity to be wasted.
Forced air electric furnaces force air through duct and room vents where an electricity-powered heater heats the air. This air is then pumped throughout the house using an electricity-powered fan. The key to maximising efficiency is to ensure that all of the heat is absorbed into the air and that no heat is wasted, which requires more electricity to heat the air.
Radiators can increase the overall energy efficiency of the home if they are used in a very large home, according to Heater Home. The furnace is placed on a very low setting and the radiator is turned on in the part of the house where the guests desire warmer temperatures. An enclosed heating element can heat oil and allow heat to gradually rise up from the top of the radiator, heating the room.
Forced air boilers heat water using electricity. The heated water circulates through the house, sometimes with the use of an electricity-powered pump. The circulation throughout the house causes heat to radiate through various locations, such as walls and the floor. This type of electrical energy radiator is cheaper when electricity prices are low, but is more expensive than fossil fuels when the electricity expenses are high.
Baseboard radiators transfer heat from a heating element to the air around the element and also heats air, which causes the air to expand and rise out of the baseboard radiator. Baseboard radiators tend to cause moisture to accumulate on the windows of the home if the baseboard radiators are the only radiators used in the home, according to Green Energy Efficient Homes. Therefore, the radiators are best used alongside other heating solutions.
Movable Radiative Heater
Movable radiative heaters direct air into a tube, and the tube is then heated with electricity. The heater also releases infrared radiation, which strikes objects and causes the objects to heat. The radiators are more likely to set objects on fire than other radiators if they are too close. Therefore, owners should purchase radiative heaters that shut off automatically when they are too close to another object.
