How Does an Electric Radiator Work?

How do you stay warm? Oil and electricity are the two most common fuels for some boilers. Electric radiators are worth considering if these options do not sound appealing. Continue below to learn about how they work, and reasons to buy.

How Does an Electric Radiator Work? 


An electric heater is a home appliance that works by converting electrical energy to heat. It contains an electrical resistor that the electric current flows converts the electrical energy into heat energy. It is common for this device to use a nichrome wire as the active heating element. Also, some types of heaters use tungsten, which also heats up quickly and absorbs much energy. This type of metal retains the energy and releases it slowly, which means that your heater can use minimal power to maintain the temperature in your room.

Compared to the gas central heating system, the radiator work in a similar way. They contain a thermodynamic fluid, usually oil, that facilitates the transfer of the heat energy produced by electricity. The liquid expands, and the radiator releases the heat to the surrounding air.

The Thermostat


Each of the radiators involved in heating a home is equipped with a very sensitive thermostat. This type of thermostat is very accurate and helps to control the temperature so that it is always at the ideal level for the home. Also, the thermostat helps to regulate the right amount of power that is needed to maintain this temperature, so that no power will waste within the home.

So, how does the thermostat balance the temperature of the radiator effectively? When you turn on the heater, it will draw full power to achieve the heat that is set. It usually takes around 5-10 minutes. Once reaching the set temperature, the radiator will stop bringing energy. At this point, the thermodynamic fluid within the home electric radiator will have rapidly expanded, and the heater will have 100% heat on its surface.

Thanks to the design of the heater, it will release this heat very slowly, continuing to keep the room warm while using a minimal amount of power. The air around the heater will become warm, causing it to rise. Cold air will rush in to take its place, creating a convection current. The warm air rises to the ceiling, cools down and then falls back down – completing the cycle. This current keeps the flow of heated air going and helps to heat the entire room.

One of the main advantages of using electric heaters is that their thermostats can be adjusted separately so that you can have different temperatures in different rooms. Also, when you leave the house to go on holiday, you will be able to turn down the thermostats on your electric heaters, which will save you much money in the long run.

 

 

Efficiency

 

Regarded as being 100% efficient, nearly 100% of the energy of the electric heater is being converted into heat and then released into the room. It is considered to be more efficient than piped in hot water heating systems because a lot of the heat is lost within the pipes as it is being sent to the boiler and the radiator.

What's more, electric radiators are more efficient because they are an “on demand” heating system. It means that there will be less risk of wasted energy.
