ELKATHERM® electric radiators lead the way in quality German engineering. Boasting a German A++ energy efficiency rating, they’re truly the future of electric heating.

What’s inside an ELKATHERM radiator?

At the heart of every ELKATHERM® radiator is a high-performance, super dense fireclay core, into which the element is directly embedded. This means no air gaps or moisture can penetrate, and allows for direct heat transfer for rapid heating of your home.

The smart, ceramic, fireclay core heats to its optimum working temperature in minutes and stays warm for hours with minimal additional power, meaning you get more warmth for your money. Once your radiator is up to temperature, it will typically draw between 15-17 minutes of electricity per hour to just top up the core and maintain your cosy home, further increasing your cost savings.

Dual heat transfer technology

ELKATHERM®'s advanced radiator technology uses a massive five times surface area to provide both radiant and convected heat.

  • Radiant heat is similar to the warmth from the sun, gently warming both people and objects in the room, creating a comfortable and natural warm feeling. Radiant heat also preserves the humidity of the room, making it more gentle on the respiratory tract and skin – ideal for allergy sufferers.
  • Convected heat warms the air in the room. Cold air is drawn into the flutes at the bottom of the radiator, heated by the internal elements, and then circulated around the room evenly, ensuring you aren’t left with any cold spots.

There’s no need for a noisy fan with ELKATHERM®'s unique design, meaning you don’t get the uncomfortable dry air associated with other forms of electric heating. Just a comfortable, quiet, peaceful environment.

Precise temperature control

Every ELKATHERM® radiator is equipped with an advanced thermostat that allows for precise temperature regulation. You can set your desired room temperature and the system will adjust accordingly to maintain a consistent and comfortable environment, without unnecessary energy consumption.

Smart heating controls

ELKATHERM® electric radiators are available with a range of control options, from simple on-radiator controls to our latest smartphone app, eComfort. Control each room individually, choosing times and temperatures to suit your lifestyle. This level of control ensures you only heat the rooms you’re using, reducing energy waste and lowering your energy bills.

Heating technology that lasts

Founded in 1954 in west Germany, ELKATHERM®'s  innovative heating solutions have always been built to last. This commitment to long-lasting heating systems is proven by their market leading 25-year guarantee on the radiator’s internal heat core.

Eco-friendly heating solutions

ELKATHERM® radiators use electricity, making them an environmentally friendly alternative to fossil-fuel based heating systems. They don’t produce carbon emissions at the point of use and are built with safety in mind, with overheat protection and the option for low surface temperature radiators.

Independently tested

An independent study conducted by the renowned BSRIA institute confirmed the excellent performance and consumption characteristics of ELKATHERM® radiators. 

ELKATHERM® is one of the few manufacturers of electric heaters whose products are VDE-certified, meaning their products adhere to European Union safety and quality standards.
