    Adjusting the surface temperature of Technotherm KS DSM Low Surface Temperature Radiators is a manual process and will require the use of a screwdriver. View the surface temperature adjustment instructions for further details. Please note that as it is a manual procedure, you may need to test and adjust the limiter several times before finding the right position or temperature level. The default surface temperature set during manufacturing is 60 °C.

    Technotherm KS DSM Low Surface Temperature Radiators come equipped with wall mounting brackets and any additional fixtures required to mount them 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. These radiators can be made into a freestanding unit when purchased with its optional feet (sold separately).

    Technotherm KS DSM Low Surface Temperature Radiators have an IP20 rating which does not protect them 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 Low Surface Temperature 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

These versions of the Technotherm KS DSM provide complete peace of mind for homes with young children, removing the worry of accidental contact with hot surfaces via their adjustable temperature limiter. The limiter allows you to restrict the surface temperature of these electric radiators to any point between 30 – 85 °C, making them suitable for use in NHS buildings when set to 43 °C or lower or anywhere there’s a need for heating that’s safe to the touch. It’s a practical and energy-efficient option for hospitals, care homes, clinics and crèches where safety is paramount.

WiFi Control

Programming the Technotherm KS DSM can be done through the intergrated control panel which is located on the side of the radiator. However, the use of the optional WiFi hub unlocks a whole new level of convenient control. With WiFi, you can download the Technotherm app to your phone and make quick adjustments to your heating on the move, giving you precision control over your heating from a handy point of access. For hands-free heat management, the Technotherm KS DSM also supports Amazon Alexa and Google Home so you can adjust your heating using nothing but your voice – a particularly good option for those with limited mobility. 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.

Quality Engineering

All Technotherm KS DSM Low Surface Temperature 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 ceramic 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.

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 LST radiators come with two thermocouples to prevent overheating, as well as a lockable keypad. 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. KS LST radiators can be wall mounted or used freestanding when purchased with their optional feet.
