5. DeLonghi Dragon 4

Next up is the powerhouse. This is the DeLonghi ‘Dragon 4’

They called it a “Full Room” heater for a reason.

DeLonghi has been in the heating game for a long time, and they’ve really gone the distance on this model. It’s 25% larger than their previous ‘Dragon’ model, and at over 27 inches high it’s the tallest on this list.

Not to mention the heaviest. The extra height and patented steel design mean this is no lightweight.

It’s for good reason, though. While the fins of the other heaters get hot, the unique design on this model keeps it cool. Perfect if you’ve got any curious kids or pets.

Instead, all of that great heat is channeled out the top of the heater, meaning the surface is safe to touch.

My one gripe with the model is the sacrifice of functionality. The controls are manual – so while it’s got a timer, it’s one of those finicky rotating clocks and not digitally controlled. And even though the design is unique and power unmatched, the price point could be a bit lower.

6. Honeywell HZ445E 360 Degree Surround Heater 

Last up, we have the Honeywell EnergySmart Heater.

Honeywell is a huge brand, and they’re great at backing up their name. This heater is the only one I’ve reviewed that doesn’t have a basic one-year warranty. It’s got a 3-year warranty instead!

That says a lot for reliability and a better commitment to their customers than most.

While it’s called ‘EnergySmart’, I’ve not found the ‘eco’ mode to be any better than the other models. That said, it’s still a fully working model that will save you plenty on your bills! I was just looking for something ‘extra special’ in that department given the name.

Outside of this, all the standard modern features are there. Digital Controls. Safety Switches. Programmable Timers. While it doesn’t blow you away in many respects, it’s a great all-rounder option

7. Russell Hobbs RHOFR5001B

The Russell Hobbs RHOFR5001B rubs elbows with traditional oil heaters but not without borrowing a few tricks from the new school. Sure, this is not the most impressive appliance we’ve seen yet but, where medium-sized flats and large rooms are concerned, this unit more than covers cold spells and months between ~August and May. Not unlike its direct (as well as indirect) competition, the model comes equipped with 3 heat settings: low heat (600 watts), medium heat (900 watts), and high heat (1500 watts). Switching between these settings, you can add a little heat, keep an average room warm, or even maintain a perfect heat level inside sizable premises. Likewise, the heater’s integrated thermostat will be regulating the temperature around the unit, keeping it optimal. Once the desired temperature’s reached, the appliance switches off. When the same area cools down, the unit automatically switches back on.

Needless to say, with its peak 1500-watt output, the model does not quite land among the most powerful oil heaters. The good news is that its weight has been informed about this decision beforehand as well. Whereas most oil-based heaters these days usually weigh around 15 kilograms, this appliance does not even reach 7 kilos, making the unit more than luggable and enabling easy relocation between rooms. As expected, the model also features an integrated handle, so you should be able to move this appliance alone without much trouble. But, when carrying it is not an option (or you don’t feel like it), the built-in castors should also do the trick, letting you roll the unit from one room to the next without applying much effort.

10. Dimplex CDE2Ti 2KW Electric Oil Free Radiator

The Dimplex Cadiz has a fairly unobtrusive design. Physically, it’s the sort of electric heater which could blend discreetly into the background. Technologically, it really does have the wow factor.

First of all, this is an oil-free electric radiator. We’re not sure how Dimplex has made this work, but we can tell you that it really does make this electric heater noticeably lighter than the alternatives.

The “oil-free” approach has other benefits too, in particular, it means the Dimplex electric heater warms up super-quickly, which is not only very convenient but also helps to save energy. In fact, the Dimplex electric heater is very economical to run, due to the efficient way it generates heat. As an added bonus, the two sides of this electric heater can operate independently of each other, which is obviously convenient as well as economical.

There is a maximum 3Kw output and a temperature range of between 5°C and 35°C (in increments of 1°C), you can set these either by manual controls on the electric heater itself or by remote control. Both are very simple to operate and we particularly like the fact that the LED display on the electric heater is so clear and easy to read. You can also set a 24-hour timer and make use of temperature memory to remember your previous settings.

How Much Does It Cost to Run an Oil Filled Radiator?

When it’s first switched on, the device will run at full power attempting to heat the oil to operating temperature. In case the radiator can’t heat the room to the required temperature, it will continue to operate at full power. It’s the worst-case scenario for calculating running costs.

You could look at the maximum power output of the oil-filled radiator and your latest bill’s cost per unit of electricity to determine its maximum running cost. Remember, an oil-filled radiator power output is measured in Watts.


Oil heaters are a great source of warmth and can provide you comfort at low costs. They’re ideal for anyone who is looking for quality retention, temperature regulation, and energy efficiency, as they can keep heat long after they’re turned off.

You might want to be in the market for one if you have trouble keeping warm at night while you sleep. You’ll need to do your research on which is right for you and whether the trade-offs are worth it. Hopefully, this guide provides you with a solid starting point.
