The electric radiator is the best option for those who want a warm environment in a short time, without a traditional heating system. But is it really suitable for all needs, and most importantly, is it cost-effective? Let’s find out.
What is the best electric radiator?
An electric radiator is a heating unit that does not require a conventional hydraulic system, where water heated by a boiler circulates inside the radiator. Its operation, as expected, is powered by electricity.
It is important to distinguish between fan-assisted radiators (such as electric fan heaters) and electric radiators themselves.
- In fan-assisted radiators, electricity passes through a heating element.
- This generates hot air.
- The hot air is then released into the room.
Electric radiators, on the other hand, are filled with a heat transfer fluid in which the heating element is immersed. The heat is transferred from the heating element to the fluid and then to the surrounding environment.
Installation is quick and easy, requiring no major structural work. Depending on their power and the size of the room, they can serve as the sole heating source or be used alongside traditional radiators or underfloor heating to enhance thermal comfort.
One of the most highly regarded types is the so-called Swedish radiator:
- It draws in cold air from the room through the lower section.
- The air is heated by a ceramic heating element.
- It is then released back into the room from the upper section of the radiator.
However, this is not the only cost-effective option. Advances in technology and ongoing research in the heating sector have led to models that successfully combine efficiency and aesthetics. These range from bathroom radiators (heated towel rails) to stylish models designed for living rooms, seamlessly blending with home décor.
How much does electric heating cost?
The combination of electricity and heating often raises concerns among users, who fear high energy bills due to excessive electricity consumption. However, the latest generation of electric radiators is designed for energy efficiency, translating into cost savings. This is also due to materials such as steel and aluminium, which heat up very quickly.
Depending on the size and electrical requirements needed to heat the room—something best calculated with the help of a specialised technician—a radiator can have an electrical power output of up to 1,800 watts.
To estimate running costs, one must consider the price of electricity and the energy price cap in this period of the year.
Electricity tariffs, however, vary throughout the day and are divided into time bands.
How much energy do electric radiators consume?
Electric radiators are designed to consume less while producing significant heat output. Certain electronic controls contribute to this efficiency.
- Basic models feature simple on/off buttons.
- Mid-range models include a temperature control dial.
- Smart and wireless models allow users to schedule heating times and set the desired temperature remotely.
These advanced models are effectively the equivalent of smart thermostatic valves used with traditional radiators. This means users can optimise energy use based on their weekly routine without excessive costs.
Electric radiators can also be controlled via a programmable thermostat, which allows users to set heating schedules and adjust room temperature. These thermostats are part of home automation systems and can be accessed in real-time via an app, providing precise, up-to-date information at any moment.
Which is more cost-effective: gas or electricity?
The question of which energy source is more cost-effective for home heating resurfaces whenever gas and electricity prices fluctuate due to economic or geopolitical factors.
- Gas remains a widely used and established energy source.
- Technological advancements have led to efficient heating solutions, such as condensing boilers, which recover energy from exhaust gases and therefore use less gas.
- Heat pumps are also gaining popularity, particularly due to EU regulations. They operate using renewable energy sources, such as air, and their only energy cost is electricity.
However, heat pumps require a significant initial investment and, in some cases, adequate space, which may not be available in all homes.
Both gas and electricity have advantages and disadvantages, but the ongoing search for more sustainable heating solutions will likely provide a clear answer to this debate in the near future.
