ELKAtherm® Heating Range

Our electric radiator range

Efficiency, value, controllability and looks are probably pretty high on your list when looking for a new electric heating system.

ELKAtherm® German electric radiators tick all those boxes.
Our system gives you quality German engineering from one of Europe’s leading manufacturers in modern electric storage heating technology.

ELKAtherm® radiators are available in more than 60 different shapes, sizes and outputs and with 192 colours available– there’s a perfect heater for every space in your home.

Slim Line Radiators

The ELKAtherm® S-Series, SN-Series and
SL-Series radiators all have a slimline, 8cm depth – less than half the size of many other heaters – letting you maximise the space in your room.

Despite their small size, the three ranges are available with outputs up to 3000, 2500 and 2000 Watts, respectively – ample for most rooms.

Small, short and tall

As well as its slim profile, the SN-Series is just 38cm high: perfect for a sloped roof space or under a window. At 23cm high, the SK-Series is low and wide, ideal for any room with a floor-level window.

Meanwhile, the SL-Series is tall and narrow. It’s a style that fits well in tight spaces, and also suits modern interiors with its unusual, upright design.

Double core options

For larger rooms needing even greater heating power in a small wall space, we have the SD-Series and SND-Series; 13 cm-deep versions of our popular S and SN styles, including a double-layer ceramic core.

ELKAtherm® Radiators – available in 192 colours! As well as more than 60 shapes, styles and outputs, our ELKAtherm® radiators are available in 192 RAL colours – giving you literally thousands of options, and every chance of finding a perfect match…

Built to use less energy

To the best of our knowledge, ELKAtherm German electric radiators are the most efficient in the world. Their unique design and construction means you can warm an entire room and use very little electricity in the process.

The ingenious, fluted design multiplies each radiators effective surface area by 5 – spreading warmth evenly throughout the room using natural convection and radiant heating, while the high-grade ceramic core distributes heat across the whole surface. In short, you get much more heat from each watt of power.

Traditional night storage heaters literally draw electricity for the full period of the Economy 7 tariff (7 hours). This results in a large amount of electricity being consumed at a constant rate.

Ease of control reduces waste

There is no cheaper energy than the part that you don’t use – and because ELKAtherm radiators are so easy to control from anywhere, you’ll naturally waste less. Quite simply, you can adjust the heat in each room – wherever you are, thus avoiding running up bills in rooms that you don’t use as much. If you go out, switching off or turning down the heating is easy and you can even ensure the house is nice and toasty for when you return.

Cheaper daytime electricity

You don’t need to charge ELKAtherm radiators overnight as you do with conventional night storage heaters, so there is no need for an expensive Economy 7 electricity tariff. There is a common misconception that Economy 7 is the cheapest tariff available and this is certainly not always the case. Although you benefit from a slightly cheaper rate at night, you are penalised with a much higher rate during the 17 hours of the day when not on Economy 7. Sometimes this uplift in daytime rates can be as much as 50%, therefore increasing the cost of everything such as ironing, watching TV or simply boiling the kettle!

Heat Your Room Evenly

When we turn on our heating we take it for granted and trust it is working in the most efficient and best way possible. The truth is that this isn’t always the case. Over the years customers have told us that they have previously experienced ‘cold spots’ with their traditional heating system – in particular cold feet! The reason for this is actually very simple! Warm air naturally rises and as such, sits above your head, leaving cold areas around your feet.

ELKAtherm radiators are different!

ELKAtherm radiators have a remarkably clever, fluted design which was created in conjunction with Leipzig University. This design increases the overall surface area by 500% compared to flat panel heaters of similar size. In turn this means they can release an increased amount of heat for the same amount of energy used. Additionally the radiators utilise convection to ensure no more cold feet! Another advantage to this clever design is that you don’t need a larger heater to do the job required, instead being able to use a smaller heater, reducing bills whilst still ensuring the right amount of warmth for that particular room.

We have had our old electric storage heaters replaced with Elkatherm Electric Radiators by Cotswold Heating Solutions. From the initial phone call to the installation we have been really impressed with the service and the product. We’ve only been using the system for a couple of months now but really like the way we can easily adjust temperatures in the different rooms from anywhere in the home as well as anywhere in the word! Great service and would recommend without hesitation.

Independently Tested

ELKAtherm are so confident of the quality and performance of their electric radiators that they opened up their doors and allowed the BSRIA, a UK based testing, instrumentation, research and consultancy organisation to conduct their own tests.

In accordance with British Standards BSEN 60675:1995, seven sensors were used to measure the temperature at heights ranging from 30cm to 2.2 metres with an ELKAtherm heater set to 21˚c. They concluded that there was just a 0.5˚c variation from floor to ceiling meaning you get warmth where you need it most.
