Product Information

Many fan heaters also have a cold air setting – they essentially double up as fans in the summer. While not as potent as air conditioners, it could save you having to fit both appliances into your house. How safe are portable electric heaters? At 76.4cm in height, the Hot+Cool Formaldehyde is quite a lot shorter than Dyson’s standard tower fans. Nevertheless, it still enjoys the attractive design for which Dyson products are well known. If you’re sitting a few feet away from this not particularly handsome oil-filled radiator, initially it’s underwhelming. The oil takes a while to warm up, plinking and plonking as it goes, and the heat that slowly emerges from the top in a “chimney” effect goes up, not out. Over time, as cool air is drawn in from beneath due to convection, the whole room heats up, but in my test it took half an hour for the temperature monitor set ten feet away to register any rise at all.

While today’s fan heaters are pretty energy-efficient, they’re not suitable for leaving on for hours on end; they still consume a lot of electricity compared to, say, standalone oil-filled heaters. In fact, most of the models in this guide will cost between 35p and 70p per hour to run, possibly more given the current high electricity prices. Portable space heater. Electric radiator an advanced PTC ceramic heater for fast heating performance at a constant temperature to ensure comfortable and safe warmth. The portable design allows you to bring the heater to any room and place it on a table, on the floor, in your hand or at your feet to keep you warm. I doubt you’d leave it on that long. This is best suited to warming up a small room like a kid’s bedroom just before putting them to bed, or in a small study while working. I tried it plugged in at desk level but it was much more effective at knee-height: the plume of warm air extends outwards and upwards for about six feet. Adjustable thermostat Using this function, a portable heater will heat the room and when the desired temperature is reached, it will try to maintain the room at that temperature. 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.Convector heaters are usually taller than fan heaters, but thin and light – making them larger, but still relatively easy to move between rooms. 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. The low noise secures your quiet sleep in a warm atmosphere. 1x Small Electric Heater. Heating Area: Approx. Compact and great for travel, it can be placed as you like, applicable for bedrooms, living rooms, offices, etc. Your heater’s power will be measured in kilowatts (kW). For most small- and medium-sized rooms, a 2kW device will suffice. All of the heaters in our review are 2kW or under. Running costs are usually calculated by the hour (kWh). High demand Not necessarily. Heaters are highly efficient at turning electricity into heat regardless of their price. You don't necessarily need an expensive heater to get 'more' out of the electricity you draw.

Frost protection The heater can be set to heat automatically when the temperature drops below 5°C, but you'll need to have it on standby for it to run, so this can limit its usefulness. 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.Apart from the thermostat the only controls here are a three-step power dial and an old-fashioned 24-hour timer divided into 15-minute segments that you pull out for ‘on’ and push in for ‘off’.

We set up each heater in the centre of our test room and run it on the maximum settings, with the room starting at a cool temperature. We monitor how much the room temperature changed over the course of an hour using temperature probes. We found the most drastic changes happen in the first half an hour and increases in temperature become more incremental after that.We use a force meter to record how much is needed to topple each heater over and a decibel meter to measure how much noise each one makes while running. Electric heaters may be essential if you live in one of the four million or so households in the UK that don’t use mains gas heating and are a good solution if you’re just looking to heat one room, or only need to heat in short, sharp bursts.
