What Are The Most Efficient Electric Radiators?

SmartWave anthracite

When in the market for a new heating system, your mind may instantly go to the costs – of installation, maintenance, and of course, the monthly overheads. Electric radiators have almost no installation or maintenance fees but, as with any heating system, running costs can vary depending on certain factors. Insulation, energy tariffs and room size can all play into those bills but making sure your heating system is as efficient as possible will help to keep them down too.

Electric radiators with advanced energy management features can help you keep running costs low. High precision individual controls unique to electric radiators can allow them to compensate for the higher price of electricity versus gas. Here we provide a breakdown of some of the most efficient electric radiators on the market.

RC Wave electric radiator

Top 5 Features for Efficiency

  • 24/7 Programming: Enables you to customise your heating schedule down to the hour, ensuring you minimise waste and keep heating bills as low as possible.
  • Dry Thermal Elements: Allow for a rapid heat-up time, but also allow the radiator to quickly respond to any temperature adjustments.
  • Precision Thermostat: The RC Wave’s precision thermostat is never out by more than 0.2°C meaning you don’t have to worry about wasting energy overheating your rooms. It stops drawing power as soon as the precision thermostat recognises the radiator is running at the set temperature.
  • Open Window Detection: In the event that you accidentally leave a door or window open the radiator switches to anti-frost mode until it detects a rise in temperature, saving on your energy bills.
  • Adaptive Start: This intuitive feature begins warming your room just before you’re due to need it, so you don’t need to waste energy factoring preheating into the RC’s schedule.

The Haverland RC Wave is one of the most efficient electric radiators in the UK. Boasting a host of features that help you maximise efficiency and minimise energy wastage, the RC Wave is designed to keep energy bills down without sacrificing on your home comfort. With its highly sensitive 0.2°C precision thermostat, this clever radiator compares drastically with other heating systems’ temperature regulation which can be out by as much as 3°C. Coming in at a minute 75mm depth, and an attractive curved frame, the RC Wave range comprises both traditional white and modern anthracite colourways to suit your personal style. Providing the same heat as a central heating radiator and packed with handy efficiency features, it’s little wonder the RC Wave is so popular with homeowners.

The RC Wave is available in three different models:


Ecostrad Ecowärme Electric Radiators

Ecostrad Ecowärme Vertical Electric RadiatorTop 5 Features for Efficiency

  • German Engineering: a hallmark of superior quality, every stage of the Ecowärme’s production is overseen by a quality control expert.
  • Ceramic Stone Core: utilising the impressive heat retention capabilities of ceramic stone, the Ecowärme locks in warmth for continued comfort even after switch off, making it incredibly efficient.
  • Open Window Detection: prevents heat loss from a drop in temperature, such as a window being left open.
  • Adaptive Start: allows the radiator to preheat before it reaches the time you programmed your heating to come on, ensuring your heating is comfortable at the right time.
  • 24/7 Programming: an essential for any heating system, programming your radiator to match your routine will prevent it from running unnecessarily

The Ecostrad Ecowärme is a German-engineered electric radiator designed for greater efficiency. The Ecowärme comes equipped with energy management features such as a 24/7 digital programmer and precision thermostat, but what sets it apart is the heating technology inside the radiator. The radiator’s core contains ceramic stone plates which help to maximise heat retention and minimise heat loss. This enables your rooms to stay warmer for longer, as the ceramic plates keep emitting heat after the radiator has stopped drawing power from the mains.

The Ecowärme is available in white and anthracite in both horizontal and vertical models.

Haverland SmartWave Electric Radiators
