About this deal
Then they assess how comfortable it is to sit in a room with the heater. Our experts ensure the room is cold beforehand, then use the heater on max to see what difference it makes. The question is: what size space heater do you really need? There are plenty of small electric heaters putting out 1kW, but it’s much better to go 2kW or bigger and reduce the temperature on the thermostat if needed.
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.The 403TSFTie is a 3 kW heater, but setting it at half power means you’ll only use around 1.5 kWh of electricity. Weight
The 3kW DXFF30TSN space heater from Dimplex is more than big enough to heat a small room, a compact space such as a campervan, or even a converted-into-office garage or a small home gym. Weight Unlike most convection heaters, the Dimplex 403TSFTie was designed to be portable and its two carry handles make it extremely easy to move. Controls As we’ve said: kW output of your heater x cost of your tariff (per kWh) = the cost to run your heater per hour. Which type of heater is the cheapest to run? For particularly draughty buildings, a halogen heater is the best heating appliance you can get. Its infrared heat focuses on heating objects rather than the surrounding air. And that’s perfect when you’re in a building with a constant flow of cold air — a small heater would struggle to keep the entire air mass at the desired temperature.However, they’re not the best heating system for large rooms with high ceilings, or spaces you’re planning to heat over a long period of time. Doing so will reduce the kWh you use, but you still have the option of getting that heat boost by cranking it to the full 3kW output. Keep in mind, too, that the cheaper brands aren’t likely to come with a warranty, compared with Dimplex’s 3-year warranty offering. Power output How the electric heaters are used can also impact their safety, explains Giuseppe Capanna, Product Safety Engineer at the charity Electrical Safety First. “Some simple steps people can take to use their heaters safely are to avoid powering from an extension lead, as this can overload and cause fires, and to ensure they are at least a metre away from combustible materials such as clothes,” he says.
