How important these features are is down to personal preference. If all you want is something to keep you warm when there's a nip in the air, and you don't care about how it looks or require the ability to control it at a distance, a decent budget electric heater should be perfectly adequate. Nearly all have some kind of carry handle for moving about and many have a safety cut-out feature, which will switch off the heater if it gets dangerously hot. We buy all the electric heaters we test. We put the bestselling heaters from popular UK retailers through these tests: Heating speed, evenness, and accuracyDue to the long list of factors that come into play to calculate your central heating costs, the only way you can confidently compare a heater to your central heating is to install a smart meter. 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. If you were to try replacing the use of your central heating by putting an electric heater in each room, it will definitely end up costing much more.

These have exposed heating elements, which heat up cold air as it passes. This often leads to slower, but more even, heating. They tend to be a little slower than fan heaters, but are quieter, and our tests found some are still pretty speedy. If you're relying on your portable heater because your boiler isn't doing its job, find out how to buy the best boiler or whether you're eligible for a free boiler or a boiler grant. Not many of them have specific temperatures in degrees °C, though, so rather than programming specific temperatures on the thermostat you'll need to experiment with your heater's settings and find the coolest setting that still gives you the warmth you're looking for. Pinning down an exact comparison of how much central heating and electric heaters cost to run is nigh-on impossible, as the factors below are just some of the variables that play a part:

The details

We've found that convector heaters and oil radiators can take more than half an hour to raise a room's temperature significantly, but a good fan heater can do this in half the time. Programmable timer Useful for setting a heater to turn on just before you get home or wake up, so there's no waiting around for the heater to warm up. Keen to optimise home heating? See our advice on boiler controls and thermostats , smart meters , and loft insulation A programmable timer, that lets you set specific times the heater will switch on. Some cheap electric heaters do have 24-hour timers that will switch the heater on at the same time every day, but some pricier heaters have digital timers that can be set to switch on at various times throughout the week. Portable electric heaters use electricity, which costs 28.62p/kWh under the current energy price cap. Depending on how effective the heater is, they can take anything from 30 minutes to an hour to notably raise the temperature of a medium-sized room, so if you're only planning on using it until the room gets up to temperature, it will likely cost you between 28 and 57p.
