  • Type: Convector
  • Dimensions: 83 x 40 x 10.7 cm
  • Timer: 24/7
  • Warranty: 2 years
  • Fit: Freestanding or Mounted

The Devola Eco is an electric convector heater that’s reasonably priced, both in upfront and operational costs. It has the standard white look of most convector heaters, not unlike that of an air conditioning unit.

The Eco is economical thanks to its accurate built-in thermostat, which can detect temperature changes within 0.5C. Because of this, it is fantastic at maintaining the room’s temperature, for example, you should find that a bedroom will never deviate more than 2C during a cold December night, keeping it nice and toasty.

Further adding to the Eco’s efficiency is the timer, which can be programmed up to an hour, every day, for a week. Try running it at a lower power during the day and increasing the temperature a bit at night – you should find that this will save you quite a lot on your electric bill at the end of the month!

It also has an Auto Open Window Detection which turns itself of automatically when the air drops by 5C, which is what happens when you open a window. Honestly, it’s a minor nuisance when someone accidentally opens a window, and the heater turns off!

Unlike most heaters, what we like about this one is that it can be used in the bathroom. It’s rated at IP20, which makes it resistant to splashes and the damp conditions of a bathroom. You have the option of either using the feet and to have it free standing, or mounted on a wall.

Overall, we love the cost efficiency of the Devola Eco 2400W. At an average cost of less than a £100 and with economical features to boot, it will keep you warm and toasty without burning your wallet.

Pros

  • Fully programmable 24/7 timer
  • Splash proof
  • Accurate thermostat

Cons

  • Programming can be awkward

What to Look For in an Electric Radiator

Power Output

Electric radiators are primarily measured by their watt (W) output, which tells you how much heat they can produce. Consequently, it also tells you the size of the room that it can accommodate.

To figure out the correct wattage for the radiator, you need to take your room’s measurement into account. As a rule of thumb, you need around 100 watts per square metre of floor area. That figure assumes a house with standard ceiling height and regular insulation. If you have space with a higher ceiling, it’s better to factor in the room’s cubic metre measurement. In this case, you’re looking at 65 watts per cubic metre.

You should also take into account the wattage of your existing radiator if you have one. Simply subtract its wattage from your room’s required wattage. That’s the power output you’d need to buy.

When in doubt, it’s better to buy an overpowered radiator than an underpowered one. Why? Because if your watt rating isn’t enough, you’ll end up overworking the radiator and increasing your electricity bill. An electric radiator with excessive wattage can simply turn itself off when the target room temperature is reached.

Type of Radiator

There are many different types of radiators, each differing in how they produce and distribute heat.

The first type is a convector heater, which relies on the natural movement of air to raise the room’s temperature. Cold air enters the radiator and gets heated up, which causes it to rise up as it is replaced by cold air in a continuous process. This is known as convection. Some units are equipped with a fan to speed this process up.

Convector heaters have the advantage of heating up a room very quickly but do so in an uneven way. They also cause the air to dry out and help spread dust around the room. It’s best suited for smaller rooms or hallways. They’re also best used together with a humidifier to counteract the drop in humidity.

The second type is an electric heating panel, which uses heated aluminium panels. This radiates heat out towards the surrounding air, in a process called radiation. The pros of an electric heating panel are that it can heat a room evenly, producing a very comfortable warmth. Areas near the radiator, however, become disproportionately hotter, so careful placement is vital.

The last type of radiator is called a thermal inertia radiator, which relies on a heating element to store and radiate heat. They are the most cost-effective option and are fantastic at retaining heat without using too much energy. Their main drawback is that they can take a while to heat up.

Heating Element Used

Thermal inertia radiators can be classified based on the heating element they use. Each has its own pros and cons, and situations where they’re preferable.

Dry stone radiators use ceramic stone as the primary heating element. Such materials are capable of producing intense heat quickly and can spread the heat around an area much faster. They’re also great at retaining heat, helping keep room temperature very comfortable. Thus, dry stone radiators are best used for larger rooms with high ceilings or open areas. However, the main drawback is that they tend to be very bulky.

Thermal fluid radiators make use of a liquid or gel with thermodynamic properties. In other words, these are substances that can naturally retain heat. Because of this, these types of radiators can heat up a room without having to overwork, making them incredibly energy efficient. They also have the advantage of distributing heat much more evenly over a wide area. Thermal fluid radiators are the choice for cost-efficient heating of large rooms.

Dry thermal radiators are the best choice for most regular sized rooms and offices. They’re usually made of metals like aluminium. The most significant advantage of dry thermal elements like this is that they can quickly heat up and cool down. Thus, temperatures can be adjusted rapidly and accurately. Dry thermal radiators also tend to be smaller and more compact, making them even more attractive for home and office use.

Freestanding vs Mounted

Electric radiators can either be permanently mounted on your wall, or freestanding units that can be wheeled around the house. What you choose has nothing to do with the heating output, but more with if you have space in your house.

Mounted electric radiators are usually slim and compact units that are no thicker than a picture frame. They are designed to be permanently attached to the wall. You can either plug them in a standard socket or have them hard-wired by a qualified electrician.

Mounted radiators are perfect if you have a crowded space, or free space is valuable. Since they’re attached to the wall, they won’t take up room. However, you need to make sure that the wall can support the weight of the radiator, especially if you have plasterboard walls.

Freestanding models, on the other hand, are just like any appliance that can be placed around the room. Most types are fitted with wheels, so you can conveniently move them around from room to room around your house.

This type of radiator on wheels is great if you want to heat up different parts of your room. For example, you might want to bring it to the living room during the day and on to your bedroom at night. They’re cheaper than having to buy a separate heater for each area of your house.

If you prefer a freestanding model, make sure the wheels are sturdy enough. You should also consider carrying handles so you can transport the radiator in between floors.

Exterior Materials

The vast majority of electric radiators will have some plastic components in addition to metal materials, particularly the end panels. Plastic parts do bring the cost down and look good when new, but they do degrade and turn yellow over time.

If you want to maintain the look and quality of your radiator, go for ones with full metal bodies as much as possible. It’s also better for the metals to be powder-coated than painted to make them last longer.

Temperature Control

The best electric radiators are fitted with a thermostat that allows the unit to control how much heat it should be producing. The thermostat should be able to accurately measure the room’s temperature, so it can, in turn, adjust the ambient room temperature much more precisely.

Ideally, thermostats should be able to detect temperature changes in 0.1 increments. If not, then a significant drop in temperature will make your radiators work harder than usual to maintain room temp.

Timers

Timers are a convenient and cost-effective feature that any decent electric radiator should have. It allows you to set a specific time at which the radiator will turn itself on or off. For instance, you might want to switch the radiator when you’re away from work during the day, then switch it back on before you come back home.

Timers can be as simple or sophisticated as you need. Most timers are simple dials that turn the heater on or off during the specific time. Others offer more advanced programming modes where you can schedule complex routines for the radiator. Some can even automatically detect your preferences and do the scheduling for you.

Whichever timer you choose, you should consider the range of interval. Range tells you how many hours in advance you can schedule the radiator; aim for 24 hours. Interval tells you the increment at which you can set your timer to. Hourly increments are the standard, but half-hour increments are even better.

Safety Limiters

Limiters are a safety feature that automatically turns the radiator off if the temperature of its surface gets too hot. It’s a precaution to prevent your radiator from overheating and causing injuries to small children.

Enclosed Radiators

When buying an electric radiator, make sure it uses enclosed elements. This limits their exposure to the air, avoiding black marks on your wall. Some “open” electric radiators are cheaper but have a more significant risk of blackening. If you plan to buy one, make sure you’re only using it temporarily.

Design

The design of your electric radiator plays a significant role, especially for wall mounted types. Since they’re going to be permanent fixtures, it would be great to have them fit in with the rest of the décor.

Slimmer electric radiators are the best choice here, as they sport contemporary designs for more modern homes. Their thinner designs are also less intrusive and more elegant. Some even have “designer” patterns on their façade like glass.

Of course, you can also opt for the “traditional” radiator if you like that look. It’s great for older homes where you want to maintain the house’s visual appeal. Alternatively, it’s also the right choice if you’re replacing an already-existing radiator in your home.

Warranty

Like any electric appliance, warranties are an essential consideration when buying. They are a rule of thumb for judging the overall quality and durability of the unit. Radiators with more extended warranties give you better peace of mind, knowing that if they do breakdown, you’ll be covered.

Most electric radiators have separate warranties for the unit itself and the electronic components. The former will usually have more extended warranties in the range of 10 – 30 years. The latter have naturally shorter lifespans, so they have expectedly shorter warranties. On average, expect around 2 years for electronic parts.
