That’s because oil-filled radiators convert nearly all of the energy they consume to heat, and even after you turn them off, they will carry on radiating warmth. They’re safer than some portable heaters, as there’s no element that could be a fire hazard, and don’t make any noise, so you can use them in a bedroom or office without being disturbed. We’ve selected the best oil-filled radiators you can buy – as well as what to look out for when purchasing. Despite the price jump from the first heater on this list, this oil filled electric radiator is actually very well costed considering the quality it offers. In terms of sheer output, the De’Longhi Dragon 4 TRD40820T can heat a room that’s 60 metres cubed, and the model has won plenty of praise from people using it in conservatories. We absolutely love the Electriq Ultraslim oil filled electric radiator. At only 800 watts, this heater is designed with your power bill in mind. (Trust us—when your bill arrives, you’ll be really glad you selected this unit.) 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. 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.

Though it was never meant to fight among the heavy weights, this 1,000W model from Celsius is still one of the best wall mounted oil filled radiators out there. For a more permanent heating solution, a wall-mounted oil-filled radiator can be incredibly handy. Not only do they not take up a similar amount of space as a portable design but they can often be used in places where a portable model wouldn’t be suitable, such as a bathroom. They’re also handy for spaces that don’t have plumbing, such as conservatories, garden rooms and insulated sheds. Now, the heating capacity afforded by a 3,000W heater is self-evident. But what makes this model particularly appealing is the blistering speed with which it can heat up a relatively large space, like a lounge. Artfully designed and manufactured, De’Longhi offers an unprecedented 10-year warranty on this oil filled electric radiator. This incredible warranty length shows that De’Longhi have complete confidence in the longevity of this product. In fact, one buyer’s review claimed their De’Longhi heater lasted 23 years before giving up the ghost. It’s not surprising though — the venerable Italian appliance company has been around since 1902, so they’ve got plenty of expertise at their disposal.Customer reactions to this heater are overwhelmingly positive — an impressive 77% of customers gave the PureMate 2500W a 5-star rating. 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. For oil-filled radiators especially, try to keep your heater on the lowest comfortable setting. Overheating is wasteful, expensive, and potentially dangerous. As a rule of thumb, the more wattage your heater has, the more you can get away with using lower settings. 3. Safety Features Like all truly great heaters, PureMate doesn’t cut corners with safety, either. It includes a housing for the power cord, and gets shipped complete with overheat protection, auto-shutoff, and tip-over safety protection.

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?Like the 7-fin variant, the VonHaus 2,500W Oil Filled Radiator is also quite portable thanks to its 4 castor wheels. Just like any other electrical appliance, an oil filled electric radiator may become defective with time — this is why some safety features are essential to protecting you should a fault occur. In terms of value, the Pro Breeze 2500W Oil Filled Radiator is arguably the overall best oil filled electric radiator on the market. Its surprisingly reasonable price point stems from the fact that this model’s been around for a while. But that’s not a bad thing — it simply means that this radiator has withstood the test of time. For your safety, the heater’s features include a secure tip-over switch, overheat protection, and automatic thermal cut-off.
