Delonghi HSX2320 2.0 kW Slim Convector Heater

Product Information

Once that desired temperature is reached, the heater won't run constantly anymore. It will toggle on and off sporadically to maintain that temperature. Cheap heaters usually have fewer features 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. For just half an hour, it'll cost you around 27p. The oil in the radiator acts as a heat reservoir, which stays hot for some time after the heater's switched off. Some are called 'oil-free' and function in a comparable way, just with an internal heating element instead of any oil.

Over the last few years they've flown off the shelves as the nights have drawn in, even after having their prices hiked up rather than cut. 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. Do you want short bursts of heat, or something to keep you warm over several hours? Some of the cheapest fan heaters run at 3kW, so are good for short, intense bursts. More expensive and much slower convectors won't get the heat going as fast, but they'll be better over longer periods. 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. 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:

The cheapest electric heaters we've tested all have thermostats that detect the ambient temperature and adjust the heater's output according to your preferred setting. They usually have adjustable energy settings and timers so you can turn the heat down if you want to, or limit your heater's running time.Cold air setting Some fan heaters can help cool you down too. They're not nearly as effective as a dedicated air conditioner, but a light breeze of cold air is better than nothing.
