How do I choose the best heater for me?

The most important aspect of finding the best heater is workout out what you need to heat the desired space. If you’re heating a whole room, you’ll need a lot more power than you would for heating personal space. 

Through OnBuy, you'll find electric heaters ranging from 350W to 3000W in power - the higher the power, the quicker it will heat a larger space. If you're heating a standard sized bedroom, for example, you'll want around 1500W of power, while you'll need more if it's a living room that needs the warmth.

If you’re wanting a quick and energy-saving solution, fan heaters work well to heat a small space very quickly - your toes will be toasty in no time! Electric panel heaters are perfect if you’re looking for a heater that will keep yourself and a room nice and warm. They combine convection heat and radiant heat for the best of both! To heat up a space quickly, electric storage heaters are great, as they emit convection heat and usually come with a high power rating. 

Which electric heater is best?

Top brand Dimplex has been a trusted name in electric heating for over 70 years and delivers high quality products to warm your home. They've create a range of stylish, energy-efficient heaters in a range of designs that are available at a great price through OnBuy.

Dimplex electric heaters are made with excellent features including oil free for safety, built-in timers and pull cords to direct the heat at any angle. Even better, the Dimplex Quantum storage heaters use low cost, off-peak energy making it economic and energy-efficient!

We have a selection of other high quality brands to choose from which offer all types of electric heaters including Homcom and Silentnight.

How much do electric heaters cost to run?

The cost of running an electric heater will largely depend on how much you are charged for electricity, but the good news is that's easy to figure out. All you have to do is multiply the cost per KWH by the power rating of your electric heater (though it's worth remembering there's 1,000W in 1KW).

So if you're charged 20p per KWH and you're using a 1000W electric heater, that would cost you 20p to run for an hour. A 2000W electric heater would cost therefore cost 40p an hour, and so on.
