Delonghi HSX2320 2.0 kW Slim Convector Heater

Product Information

This slim-line convector heater is one of our most popular units. It boasts a powerful 2000 Watt output along with 3 heat settings giving you great control in achieving the deisred temperature. It also comes with a thermostat dial for you to set and maintain the temperature of the room to your desired level. 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. Cheaper electric heaters tend to have fewer features than more expensive ones. Compared with more expensive ones, a cheap heater is less likely to have:

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.

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. If you have the thermostat of your heater set to a desired temperature, the heater will toggle on and off once it reaches that temperature – depending on what's needed to maintain it. The heater won't operate continuously, so won't cost you as much to run. Are electric heaters cheaper to use than central heating? We buy all the electric heaters we test.

Most of the cheaper, simpler heaters we tested have a dial thermostat that doesn't let you choose specific temperatures in °C. You'll likely need to buy a more expensive model for that. 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. Keen to optimise home heating?

On average, most electric heaters run at a maximum output of 2kW. In other words: if you run your 2kW electric heater at full blast for one hour, you'll be paying around 55p.

If you have a combi boiler, you can make money savings right now by running it more efficiently. Boilers are able to run as low temperature systems, but many are set up to run at full tilt, costing you extra money. We've noticed that prices tend to edge up the closer to colder weather we get - we've seen some price increases over the last few weeks. So if you want to get a cheap electric heater, our advice would be not to hang around. 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.Some portable heaters have useful extras, such as an LCD screen that displays the current temperature or a remote control for turning the heater on from across the room. These features may come in handy: No installation or assembly required - Simply plug it in and use immediately Speed up heat distribution when necessary with a choice of three fan assisted settings.Move it from room to room with ease using the built-in carry handlesIts fitted with a thermostat which helps maintain the perfect temperature.

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. With that in mind, you won't be surprised to hear that you'll need to run it for a bit longer than other heaters to benefit from the heat it gives out.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.
