What are German electric radiators?

German electric radiators are known for their superior level of quality control, manufacturing, and technology. Designed to last, they boast advanced programming, energy-saving features, and traditional, elegant aesthetics.

German radiators stand out for two main reasons: their manufacturing and traditional ribbed builds. Crafted to impeccable standards, these radiators represent some of the most advanced heating systems on the market, combining innovative design with high-quality craftsmanship.

Our German electric radiators undergo meticulous production and scrutiny by specialised experts, each focusing on a specific part of the process.

Quality German manufacturing

The label "Made in Germany" is synonymous with efficiency and superior quality, reflecting a commitment to the highest manufacturing standards. Our German electric radiators undergo meticulous production and scrutiny by specialised experts, each focusing on a specific part of the process. Ensuring consistent quality every time, each radiator even comes with a unique code that allows it to be traced back to the manufacturing plant. This meticulous approach to quality control not only guarantees longevity but also ensures smooth performance throughout its lifespan.

Key benefits of German electric radiators:

Superior energy efficiency

Their ceramic stone core delivers more radiant heat than other electric radiator types, ensuring rooms are kept warm using less energy.

Elegant, traditional aesthetic

Their pleated fronts and stately aesthetic integrate well with central heating radiators, as well as looking the part in period properties and classically designed homes.

Great for hard-to-heat spaces

Able to push out heat with powerful intensity, they’re ideal for draught-prone spaces and rooms with high ceilings.

How do German electric radiators work?

German electric radiators utilise heat-retentive ceramic cores and deep-ribbed fronts to deliver an even split of convection and radiation. With superior thermal properties and an increased surface area, they benefit from swift heat-ups and gradual cooldowns, ensuring cost-efficient and consistent heating.

Ceramic heating element

German electric radiators elevate the heating experience by using composite ceramic to generate warmth. What’s so good about that? It’s simple: ceramic boasts a swift heating process and is great at retaining warmth over time. Plus, it can achieve high temperatures without the risk of cracks or degradation. A ceramic core embodies a perfect blend of rapid heating, heat retention, and durability, integral to the efficiency and cost-effectiveness of German-made radiators.

While German radiators share a ceramic core, their internal structures may differ slightly:

Technotherm radiators and the Ecostrad Klasse iQ feature an entire body filled with ceramic, with the wire element baked inside the bricks. An increase in thermal mass results in improved heat retention, allowing you to feel the warmth for longer.

The Ecostrad Ecowärme contains two ceramic bricks suspended above an aluminium X-bar element. This balances the efficiency of a ceramic radiator and the responsiveness of a panel heater, allowing for quicker heat-up times.

50:50 heat transfer

German radiators stand out for their impressive heat retention, providing comfortable warmth that lasts longer. Especially crucial for efficiently heating challenging spaces, they deliver 50% of their heat as radiation, which is far less likely to get lost to draughts or high ceilings. Instead, it’s effectively absorbed by the fabrics of the room. This allows the walls, objects, surfaces – even you – to radiate heat back to the rest of the room, enveloping the space in long-lasting comfort. With the other 50% delivered via convection, you’re still benefiting from a toasty current of warm air. It truly is the best of both worlds!

Deep-ribbed design

Their pleated fronts are more than just an aesthetic choice. These deep ribs are there to maximise surface area – in some cases, six times more than flat-fronted radiators. This makes it much easier to make contact and heat the air, allowing spaces to warm up faster.

How long do they take to heat up?

It's typical to expect German radiators to heat up within ten minutes. The combination of the ceramic element and deep ribs allow German radiators to be incredibly responsive – slightly slower than dry thermal radiators using aluminium elements but much faster than oil filled radiators.

Efficiency & running costs

100% efficient at point of use, German electric radiators come in-built with a range of energy-saving features designed to slim down running costs. By using seamless manual programming or WiFi control, set weekly schedules and view energy statistics in real time. Thanks to their superior heat retention and precision thermostats, they typically only need to run for 15 minutes an hour, keeping you comfortable for a fraction of the cost.

Are they expensive to run?

German radiators are amongst the most cost-effective electric heating systems. In terms of efficiency, all electric radiators are 100% efficient at point of use, meaning every bit of electricity drawn from the wall is transformed into useable heat. German radiators, however, take this to the next level. Fitted with precision thermostats, they can accurately monitor room temperature to keep the set level from drifting. Once they’ve warmed up, the radiator will stop running – only turning back on top up the heat. In fact, German radiators like the Klasse iQ can continue radiating heat for up to 45 minutes without power, resulting in huge savings at no expense to your comfort!

Programming & energy-saving features

Spotting a German electric radiator extends beyond its physical appearance or heating technology; it's also in the control features designed to enhance your experience and keep energy usage to a minimum.

Recessed control panel

A distinctive feature you’ll find is the digital display located on the side of the radiator. This intuitive interface provides easy access to programming options: effortlessly adjust settings, set schedules, and customise heating preferences without having to bend down and fiddle with a dial. The recessed control panel reflects German engineering precision at its finest, embodying functionality at its most discreet.

WiFi app control

Embracing modern connectivity, German electric radiators often come equipped with WiFi app capabilities. This advanced feature means you can manage your radiator remotely via a smartphone or even connect it to a home voice assistant. Whether you're at home or on the go, smart control not only adds a layer of convenience to your daily routine but also contributes to your home’s overall energy efficiency, ensuring your space is comfortably heated without worrying about waste.

On top of intuitive programming, German electric radiators are well known for their inclusion of advanced energy-saving features:

Precision thermostats

Removes the need for continuous operation by accurately measuring room temperature, only turning the radiator on to top up the heat.

24/7 programming

Reduces waste by creating an hour by hour, day by day heating routine for each room so you always know when your radiator will be running.

Open window detection

Turns the radiator off in the event a door or window causes the room to lose heat too quickly.

Adaptive start

Works out when to start pre-heating your space so it’s at the right temperature at the right time using minimal energy.


Switches your heating off when you move out of a set radius from your property and activates when you re-enter the set range.

Energy usage statistics

Installation & maintenance

DIY-friendly and maintenance-free, German radiators are incredibly simple when it comes to installation and upkeep. A key benefit is their portability: many come with radiator feet or castor wheels as a purchasable extra. Perfect if you require ad-hoc heating in a lesser used space, like a garage workshop or guest room.

Are they DIY friendly?

Yes – one of the main benefits of German electric radiators are how easy they are to install, which includes being DIY-ready straight out of the box! On top of that, they also have a lot of flexibility when it comes to mounting options:


  • Wall mounted installation – This is the default choice if you plan to make them your primary room heater. German radiators come equipped with all the necessary fixtures and fittings for easy wall mounting. Simply mount, plug in, and you're good to go.
  • Freestanding installation – With the option of purchasable feet or castor wheels for low and horizontal models, this setup is perfect for those who want the flexibility to move the radiator from room-to-room as a convenient top-up heater.

How much maintenance do they need?

With zero moving parts and no risk of carbon monoxide, German radiators eliminate the need for regular servicing. The only occasional upkeep might come from the settling of dust between the fins. In which case, a simple dusting with a cloth is all it takes to keep your German radiator in top condition! Plus, with long warranties, any potential issues are easily addressed.
