You will have to allow for enough time for the heater to warm up before the space reaches a comfortable temperature, maybe 20-30 minutes. Some are equipped with a timer that you can use to preheat the room prior to use. If the heater is equipped with a thermostat, it can be set to switch off when the oil reaches the desired temperature. Also, some radiators have adjustable settings that change the wattage output. You can also use the above formulas to calculate the cost of each setting. It’s a good idea to buy a radiator based on the size of the room you will mostly use it in. Due to the way that oil-filled radiators work, larger heaters will consume more energy to heat the oil inside, but will also be more effective at heating a large room because of the increased surface area. Compact oil radiators often won’t heat a large room as well, but many make up for their smaller size by including more technology to help them distribute heat around a space. Like with all space heaters, it’s best to use the VonHaus 1,500W oil filled radiator in well-insulated rooms. Keep in mind, too, that this heater is designed for occasional use. The size of the radiator, the power source, and the heat output are the primary — but not the only — efficiency determinants. 1. Size of the Radiator

Once you know the running cost of your oil-filled radiator, you can compare that cost to other heating methods. With integrated safety functions, the radiator provides peace of mind when in use. Overheat protection ensures that in the unlikely event that the radiator overheats, the power will automatically shut off. Remote control— As with a TV set, a radiator’s remote control allows you to switch the heater into a setting of your preference.Wattage can be used as a guide to heat output. Roughly allow 100W per square metre (or 0.4kW per cubic metre) of the room in a well-insulated home. How much should I spend on an oil-filled radiator? The current average electricity cost in the UK is 33.2p per kWh. In addition, the average oil-filled radiator runs on electricity and has a 1,500-watt input. So: With a slim, portable design, the PureMate 2,500W Oil Filled Radiator is an exercise in engineering efficiency, cramming 2,500 Watts into a satisfyingly compact, high-performance heater. Suitable for use in the home, office, or garage, this small oil filled radiator from PureMate proves its versatility at a very attractive price point. When gauging value, you should look past the upfront cost. A cheap oil heater might look good on the surface, but unfortunately, all cheap things tend to cost more in the long run. This is especially true for oil filled radiators.

There are a couple of downsides. The 24-hour timer only allows you to set one switch-on and one switch-off a day and if you accidentally unplug it, it will lose your settings. This isn’t the end of the world, but something to bear in mind if features are important to you. Note that despite its IP-20 rating, this radiator is not waterproof, and therefore not suitable for bathrooms or the outdoors. Energy is usually charged by kilowatt hour (kWh). So, for every 1,000 watts of an appliance, it uses 1 kWh.An electric radiator with a sizeable output and high energy consumption may be more efficient than one using less energy to produce less heat. At any rate, ensure you choose a heater that’s not wasteful. They’re also safer than some portable heaters because there is no element that could be a fire hazard and are very quiet, so won’t disturb you while you try to meet deadlines or are just trying to relax in front of the telly. Many people have them by their feet beneath or next to their desk or table. How much do oil-filled radiators cost to run? The best oil filled radiators offer an array of settings to help you operate the heater safely and efficiently. When choosing your model, look for simple energy-saving features, like remote control, a timer, thermostat, programmability, and others.
