With these figures now explained and knowing what you spend currently on your energy, you should be able to work out how much you’ll be saving from running one. Do oil-filled radiators use a lot of electricity per hour? So, if you used this heater on the lowest 400 watt setting for 1 hour a night during off-peak times, you would be spending just 6.4p per day on your energy, that’s only 44.8p a week to heat your room.
Your energy provider will charge you for each unit of electricity you use. In other words, for each kilowatt-hour (kWh) consumed. Pinning down an exact comparison of how much central heating and electric heaters cost to run is nigh-on impossible, as the factors below are just some of the variables that play a part: The adjustable thermostat and 3 heat settings make it easy to select a temperature to suit you and your surroundings. The 2kW total heat output is ideal for rooms up to 20m2. Look at the table below to get an idea of the size oil radiator you’ll need to warm your room. These are the sizes in watts your heater will need to be to control your rooms temperature. Room Size

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 When the price of gas soars, a portable electric heater (sometimes known as a space heater) is worth considering. Used properly, with judicious use of the thermostat, they can be economical – particularly for heating bedrooms and for occasional use in the coldest parts of the house. “When gas prices are unaffordable they may help cut bills if used sparingly,” says Rob Bennett, technical service manager at Pimlico Plumbers. “But electricity is not exactly cheap at the moment either. So you’re looking for the most heating output from the lowest electricity usage.” Central heating is much more effective at maintaining a stable temperature over a longer period, whereas the heat from an electric heater will soon dissipate if the rest of your home is cold. 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.
Oil heaters come with a control dial so you can choose to run the heater on a low, medium, or higher setting.
Due to the long list of factors that come into play to calculate your central heating costs, the only way you can confidently compare a heater to your central heating is to install a smart meter. You then divide your weekly heating cost by the number of hours you have it switched on and compare that figure to the cost of running your heater.
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.
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. According to technical service manager at Pimlico Plumbers Bennett, these are the most efficient on the whole. They use an electrical current within thermal oil, heating the oil and circulating it around the heater, a bit like water in a radiator. They are convection heaters, meaning that as the heat rises it draws in cooler air in underneath to be heated in turn - an effect that works best in well-sealed rooms.
Programmable timer Useful for setting a heater to turn on just before you get home or wake up, so there's no waiting around for the heater to warm up. Of the 41 products in the Heating and cooling category, 14 were more expensive than RUSSELL HOBBS RHOFR5002 Portable Oil-Filled Radiator and 26 were cheaper. Prices from Russell Hobbs We buy all the electric heaters we test. We put the bestselling heaters from popular UK retailers through these tests: Heating speed, evenness, and accuracy 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.If you’re running a 1000-watts to 2500-watts radiator and it’s currently on the lowest setting, you can expect to be running in the lower range of 1000-watts (1 kilowatt per hour). Consider the price. We’ll dive into a lot more detail on the price of RUSSELL HOBBS RHOFR5002 Portable Oil-Filled Radiator shortly, but in terms of quality, the obvious advice here is ‘you get what you pay for’. It’s really just being aware that if you’re buying the cheapest of the Heating and cooling from Currys PC World you might not expect the same level of quality as you’d get from a decent quality product like RUSSELL HOBBS RHOFR5002 Portable Oil-Filled Radiator. Let’s take a look at RUSSELL HOBBS RHOFR5002 Portable Oil-Filled Radiator in more detail and see what makes it worthwhile of a review score of 9.2 out of 10. 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’.
