    The Technotherm KS DSM Smart Heat Retention Radiator comes equipped with a wall mounting bracket and any additional fixtures required to mount the radiator to the wall. Mounting the KS to the wall is an easy DIY task and clear instructions are included in the manual. To install, simply drill into the wall in the desired place, position your mounting bracket and slot the radiator into the bracket to secure. All that’s left is to plug the KS into a socket.

    The Technotherm KS has an IP20 rating which does not protect it from water. We do not recommend electric radiators or panel heaters for bathroom installation because of the temptation to hang towels over them to dry, which can block ventilation and create a hazard.

    Care must always be taken when connecting multiple radiators or heaters to avoid overloading the ring main of your property. If you are unsure, contact a qualified electrician for advice. For a professional installation, cables can be shortened and the heater connected to the mains supply by a fused spur. This work must be carried out by a qualified electrician.

  • Warranty
    Technotherm KS DSM Smart Heat Retention Radiators come with a 15 Year Manufacturer’s Warranty on the radiator body and ceramic stones, and a separate 2 Year Manufacturer’s Warranty on the electrical components.

  • What You Will Need

The Technotherm KS DSM Smart Heat Retention Radiator is the new gold standard in home heating, offering intelligent control alongside efficient heat storage technology. Using patented Magmatic® stone tablets, the Technotherm KS is able to retain warmth for longer, and is a system so efficient that it can continue to emit heat for up to 45 minutes without power. Combined with its increased surface area – up to 6 times greater than other models – the Technotherm KS is German engineered heating that few others can match.

WiFi Control

Use the Technotherm KS DSM with its WiFi hub and you’ll always have access to your heating: just reach for your phone, tap through the app and your radiator will respond in seconds. Prefer hands free control? The Technotherm KS DSM also supports Amazon Alexa so you can adjust your heating using nothing but your voice. This smart radiator is even intelligent enough to know when you’re on the way back home with its innovative geolocation feature. When enabled, it switches the heater to a lower temperature when you move a certain distance from your property, then when you’re returning, it’ll revert back to your normal comfort temperature. The app also provides energy usage statistics and a guest account function, which offers control for temporary users but without allowing access to your full settings - a great feature for holiday lets and rented properties.

Heating Technology

All Technotherm KS High Heat Retention Radiators come with a 15 Year Warranty to reflect their outstanding build quality and heating technology. Heating elements are laid and set directly into the stone tablets that span the length of the radiator for uniform warmth that heats your rooms from top to bottom. This means more radiated heat, less heat loss through draughts and reduced energy bills as a result.

Technotherm are so passionate about the construction of their electric radiators that each stage of production is closely monitored, tested, and approved by one of their dedicated quality control managers. This approach ensures every product meets and maintains Technotherm’s impeccable standard and every one of their products comes with a unique code that can be traced back to the manufacturing plant - helping them to identify who built and signed-off each radiator at each stage of the development.

Innovative Design

The considered design and superior construction of these German electric radiators extends down to the smallest details, such as their individually spot-welded ribs, which greatly reduce the amount of noise occurring from heat expansion. For extra safety, Technotherm KS storage radiators come with two thermocouples to prevent overheating, as well as a lockable keypad. You're also free to mount the KS DSM with the thermostat either on the left or the right for greater flexibility when installing. If you’d rather not use the 24/7 programming feature via the app, you can also program your radiator using the control panel, as well as access its dynamic start and open window detection features. 

If you’re looking to heat a family home, nursery, or healthcare property, you can even purchase low surface temperature versions of the Technotherm KS DSM that can be limited to lower, safer temperatures for use around children or vulnerable adults.

Smart, 21st Century Heating
Technotherm’s KS DSM high heat retention radiator is a sophisticated mix of cutting-edge control and innovative technology. All parts of its design are made for maximum efficiency: it has optional WiFi app control so you can check and adjust your heating system on the move, and also uses thermal ceramic stones which retain heat for longer.
Heating technology that does more

Technotherm’s Magmatic® stone tablets bring heating efficiency to a whole new level. They use specially formulated ceramic, which is poured and set into place around the heating elements to make them air-tight and secure. The elements always have direct contact with the ceramic for effective heat diffusion and retention so your radiator stays warmer for longer. The Magmatic® tablets inside the KS span across the whole of the radiator body for an increased amount of radiant heat, keeping your room at a uniform temperature from floor to ceiling.

Cooling Times The images below show the approximate temperature during the cool down process, after the radiator has been switched off.
Revolutionary control for today’s world

The Technotherm WiFi hub transforms the way you heat your home by making your system accessible anywhere, anytime. Using the Technotherm heating app, you can adjust your DSM radiators from your phone or tablet with just a few taps of the screen, so no matter where you go, your heating is always to hand. Change your programming, manage your temperatures, or switch your electric radiators on and off, all from one convenient point of control. You can also control your radiators using a laptop or desktop PC by signing into your Technotherm account online.

Anticipating your needs ahead of time

With the app’s intelligent geolocation feature, your Technotherm DSM radiators save energy automatically every time you’re away from the house. Whenever you leave a set radius around your property, the geolocation feature will turn your radiators to a lower temperature to conserve power; then when you’re on the way back home, they’ll switch back to comfort mode to ensure your rooms are comfortably heated the moment you step through the door.
