How do electric radiators work?

An electric radiator converts electricity directly into heat, making it an energy-efficient option. Unlike a gas boiler system, there’s no heat lost through pipework, so all the power used is converted into warmth. These heaters contain an electric element. The element heats metal panels or a heating fluid (like oil), which transfers heat to the air and the surrounding room.

Different electric radiator types provide varying benefits:

  • Oil filled electric radiator stores heat in thermal fluid, staying warm for longer even after switching it off
  • Panel electric radiator heats up quickly, making it ideal for rooms where you want instant warmth
  • Convector radiators often consume less energy than other electric heater types as they circulate warm air, making them suitable for energy-conscious homeowners

Modern options such as a WiFi electric radiator, programmable electric radiator, or smart electric radiator let you precisely control your room temperature via thermostats, apps, and timers. This allows you to heat each room efficiently.

Are electric radiators expensive to run?

Running costs depend on your electricity tariff, insulation, and how efficiently you use the radiator. Whilst electricity is typically more expensive per unit than gas, an electric radiator with thermostatic controls and timers ensures you only use the heat you need. Many models, such as a thermostatic electric radiator, keep bills down by cycling heat intelligently. For heating small spaces or a single room, a compact electric radiator is usually cheaper to run than central heating.

How do you choose the right wattage for an electric wall heater?

When buying a wall mounted electric radiator, choosing the correct wattage is crucial. Too low, and the room won’t feel warm enough; too high, and you’ll waste energy. The best way to find out what heat output you need is by using our BTU calculator, which accounts for the size and insulation level of your room. Then, with the calculated value, simply shop online with us at Builder Depot, using our BTU filter on electric radiators.

Where are electric radiators compatible?

Electric radiators are a great option for rooms where traditional central heating radiators cannot be plumbed in. However, they are less suitable for areas where the power supply is limited (for example, outbuildings without a mains connection). Always ensure wiring is carried out safely by a qualified electrician.

Some things to note:

  • A bathroom electric radiator (also known as an electric towel radiator) must have an appropriate IP rating for wet zones, but they’re perfect for keeping towels warm and bathrooms dry
  • In conservatories, a slim electric radiator can provide supplementary heating where extending central heating isn’t practical

How do you turn electric radiators on and off?

Most modern electric heating radiators are simple to operate. They usually have a manual switch and a thermostat for quick, flexible use. High-end designer electric radiators and WiFi electric radiators can be controlled via smartphone apps or integrated with smart home systems, giving you full remote control.

How do you clean and maintain electric radiators?

Cleaning an electric radiator is straightforward. Once switched off and cooled, wipe the surface with a soft cloth and mild soapy water. Avoid abrasive cleaners, especially on coloured finishes.

Unlike traditional radiators, there’s no need for bleeding or flushing, which makes the electric radiator low-maintenance. Aside from occasional dusting and ensuring air vents remain clear, these radiators are virtually maintenance-free.

Are electric radiators more difficult to maintain than traditional radiators?

No, in fact, they’re easier! Electric radiators are a sealed unit with no pipes, valves, or boilers to service. They don’t suffer from leaks, corrosion inside pipework, or trapped air like central heating systems. For most households, this makes them a long-lasting, low-hassle choice.

Why choose an electric radiator?

From a portable electric radiator for occasional use to a luxury designer option for a focal point in your living room, these heaters combine efficiency with versatility. Quick to install, low maintenance, and available in both classic and contemporary styles, they’re ideal for any property.

Whether you need a flat panel electric radiator for a modern aesthetic or a thermostatic electric radiator with smart controls, you’ll find an option to suit your space when you shop at Builder Depot.
