As is commonplace on this list (but should never be taken for granted), this heater features three heat settings, which is particularly useful for keeping energy costs down. VonHaus has also included a chunky two-year warranty, which is perfect for people who want to be financially ensured their heater will stand the test of time. Who Should Buy This? We’ve already mentioned some of the safety benefits of electric heaters (such as not having flammable fuel), but there is also no risk of carbon monoxide poisoning (which is a risk in faulty gas heaters). Something we’ve already touched on but is worth reiterating is making sure that you don’t put objects too close to the heater, including your body. Oil-filled heaters will take longer to cool down after being turned off, which could be a positive aspect; however, convector heaters will typically heat up a room fast. Our choice for the most energy-efficient would be a halogen heater. These heaters have a low power rating. That makes them one of the cheaper options compared to other gas and electric models. This is because their heat is focused on heating you, so money isn’t being wasted heating an entire room. And with any added key features such as thermostats and timers, they’re a no-brainer.

Timers are another great addition to any of the best energy-efficient electric heaters. Alongside a thermostat, you could set it to come on just before you wake up knowing that the thermostat will turn it off as soon as the place is warm enough. Or, set the off timer. Either way, taking the heater out of action when it's not needed is the way to go. Heating method Conveniently, when the thermostat detects that the room’s temperature is within +/– 2 ℃ of your setting, the radiator will temporarily deactivate to save energy and keep your room at a stable, comfortable temperature of your choosing. Unlike some brands (especially those who trade off components for price), Donyer Power has all the bells and whistles one could hope for, including handles (for portability), timer, three heat settings (up to 2,000 W), the ability to be mounted onto a wall, and overheating protection in three levels (including automatic temperature control, manual temperature control, and fuse).The three heat settings are as follows: Setting 1: 750 W, Setting 2: 1250 W, Setting 3: 2000 W. Setting 3 actually means that both switches are turned on (as opposed to one or the other). The inbuilt thermostat ensures that the heater always keeps the room at a steady heat. Who Should Buy This? Our second spot would go to infrared heaters. These are great at heating large spaces if you have an open-plan living space and don’t mind shelling out initially as they come with higher unit costs. Anyone who cares about safety should consider this heater. Its MICA heating element has also been carefully constructed with safety in mind; additionally, it has been designed to be silent and long lasting.

The Dimplex 403TSFTie electric convector heater with Turbo Boost and Timer is a true workhorse. With a solid output of 3 kW, Dimplex promises “superfast warm-up” with all four of their variants. For this item, though, we will just be focusing on the Turbo Boost model. An important note from the manufacturer includes the recommendation of keeping the temperature control knob at maximum if you want to ensure that your unit remains on continuously. Who Should Buy This? Despite its lower power output, Duronic has still managed to ensure this heater will have your room warmed up in under a minute, which is great news for those who don’t like to wait long to feel the heat. However, in case 1.5 kW doesn’t cut it, Duronic has other models with higher outputs in the same form factor (albeit at a higher price point). Finally, safety is paramount. For best results, ensure that your heater has some kind of safety measures in place. Such safety measures include overheating protection, tip-over protection, and automatic cutoff.

The DONYER POWER Convector Radiator Heater with Adjustable Thermostat is a tried-and-true heater with decent power output and a high degree of portability. All electric heaters should state their energy consumption. This is written as kilowatts per hour. For instance, a heater with a rating of 1.5kWh (kilowatt-hour) will use 1.5 kW for every hour of use. You can find out how much you're charged by your energy supplier, and then calculate how much your electric heater will cost you to run. Thermostats and timers An oil-filled radiator is very similar to a regular water-filled household heating system. Oil lasts for years and doesn't evaporate as water would. It's also an efficient conductor of heat. The metal fins or casing of the heater will heat the air which then rises. Infrared When it comes to electricity, having discounted the inconvenience and safety issues with gas, this isn't a straightforward choice. Much of your final decision will, of course, come down to the specific energy consumption stated in the product spec. However, some heating technologies are more or less comfortable depending on your personal preference.
