Product Information

The best electric heaters can help stave off the autumn or winter chill by providing a quick burst of concentrated warmth wherever you need it in your home.

In our tests, we set every heater to run at full blast so you can see the maximum amount it cost to heat our medium-sized test room. So, with an increasing number of remote workers now relying on an oil-filled radiator to warm up their work spaces, is this something you should be considering?The rates for Economy 7 energy therefore may differ, but will hopefully still give you an idea of which types of room heaters have the cheapest running costs. They tend to be a little slower than fan heaters, but are quieter, and our tests found some are still pretty speedy. When the element heats up, the warmth is transferred to the fluid, which then circulates around the appliance and warms itsmetallic panels.

You can do this by dividing the watts by 1,000 and then multiplying by the current electricity cost. As well as how quickly the average room temperature increases, we also use probes to check for any areas significantly hotter or cooler than the rest of the room. These can still be bought, but they aren't as popular or widely available as fan or convector heaters. Although the comparison might make your electric heater look cheaper to run, bear in mind that it will only be heating a much smaller area, whereas your central heating will be aiming to heat your whole home.While this will obviously vary depending on the size and type of your oil-filled radiator, there are ways of calculating the running costs of the models you are interested in. You will have to allow for enough time for the heater to warm up before the space reaches a comfortable temperature, maybe 20-30 minutes.

Our tests also found that they're rarely 100% accurate and will probably think the room is a couple of °C warmer or cooler than it is.We monitor how much the room temperature changed over the course of an hour using temperature probes. Convection heaters work by circulating air through the room by the process of convection – where warm air rises and cold air sinks. You then divide your weekly heating cost by the number of hours you have it switched on and compare that figure to the cost of running your heater.

We set up each heater in the centre of our test room and run it on the maximum settings, with the room starting at a cool temperature. They’re also safer than some portable heaters because there is no element that could be a fire hazard and are very quiet, so won’t disturb you while you try to meet deadlines or are just trying to relax in front of the telly. This 2000W oil-filled radiator has three heat settings and comes with a thermostat and anti-frost device and 24-hour mechanical timer. But when the cold weather closes in during Autumn and Winter, it’s easy to get carried away with exactly how much electricity we are using, especially when it comes to heating your home.Perfect for bedrooms, garages, conservatories or offices, our oil filled radiators come with an adjustable thermostat so you can control the heat of the room.
