We've found some of the cheapest heaters available right now and shared some tips on what makes a heater truly good value. Read our full story on illegal and dangerous plug-in mini heaters for sale on online marketplaces to see those we identified as having serious safety risks.

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. 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.We assess how easily each electric heater can be set up and how easily understandable the controls and settings are. We used any handles to lift the heater and move it around. While some heaters can be used straight out of the box, others have complicated program and timer settings. With little hope of temperatures rising anytime soon, it's possibly time to think about cost effective ways to stay warm and snug indoors.

They're not nearly as effective as a dedicated air conditioner, but a light breeze of cold air is better than nothing. 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. 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. These can still be bought, but they aren't as popular or widely available as fan or convector heaters.This oil-filled radiator really is mini - it's not much bigger than some of the smallest heaters we've tested.

Due 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. However, many of the 2kW electric heaters we've tested tipped above and below that power output over the course of an hour's use in our tests, resulting in costs from 9p - 83p. 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.
