    The Technotherm KS TDI High 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 TDI High Heat Retention Vertical 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.

Sourced from one of Europe’s leading manufacturers, the Technotherm KS TDI High Heat Retention Radiator is a cut above the rest when it comes to efficient home heating. This advanced electric radiator uses patented Magmatic® stone tablets to provide exceptional heat retention and will continue to emit heat for up to 45 minutes without drawing electricity. With its deep rib exterior, boasting a surface area 6 times greater than a flat radiator, the Technotherm KS is optimised to perfection – an affordable yet high-end heating solution.

Heating Technology & Quality

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.

Programming & Control

To give you greater control, this version of the KS storage radiator comes equipped with 24/7 digital programming via its TDI interface, so whatever your schedule, you can create a routine to seamlessly fit around your life. It’ll also dynamically pre-heat your spaces ahead of time for invitingly warm rooms that are the ideal temperature the moment you step through the door. The Technotherm KS will save you money even while you’re out of the room with its open window detection feature, interrupting the heater if it detects a strong draught to stop your system wasting energy.

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 TDI with the thermostat either on the left or the right for greater flexibility when installing.

This Technotherm KS has a lean, vertical body designed to make best use of your space. Install it in a kitchen to make room for more storage, fit it in a narrow hallway to keep your walkways clear, or place it in an alcove that would otherwise go unused – our Technotherm KS vertical electric radiator offers a versatile solution to suit a range of applications.

Blending traditional aesthetics with state-of-the-art technology, the Technotherm KS TDI High Heat Retention Radiator is a reliable, energy-efficient heating system that’s unlike any other.

Technotherm KS TDI Timeless design, exceptional quality.
Outstanding Efficiency
The Technotherm KS uses patented Magmatic® ceramic tablets that are so heat retentive, they can continue to emit warmth for up to 45 minutes without power.
Effective Deep-Rib Design
Even its exterior is optimised for efficiency. The deep pleats on the Technotherm KS maximise its surface area for greater contact with the air and improved heat distribution.
Heating That’s Built to Last
Technotherm KS radiators use heating elements that are laid and set directly into the ceramic for superior heat diffusion and a long product lifespan.
More Radiant Heat, More Comfort
Unlike most radiators, the Technotherm KS provides 50% radiant heat, keeping your rooms warmer for longer whilst minimising heat loss.
Quiet Operation
Each pleat on the housing is individually spot-welded into place to keep expansion noise to an absolute minimum.
15 Year Manufacturer’s Warranty
The Technotherm KS is German-engineered heating designed to stand the test of time and comes with a 15 Year Warranty on the heating elements and stones.
Reliable, Efficient, Elegant
The Technotherm KS TDI represents German engineering at its finest, with every aspect of its design carefully considered to deliver the very best quality product. From its increased surface area to its heat retentive thermal elements, the Technotherm KS TDI is home heating optimised for efficiency.
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.

Easy DIY installation

Every Technotherm KS radiator comes with a 1.8m cable, a UK fitted plug and wall mounting brackets so you can have your new system set up in no time at all. Installation takes a matter of minutes and is so simple that you can even do it DIY using a few tools you may already have around the house. No expensive or time-consuming professional callouts needed.

Adaptable control to fit your lifestyle

Using the TDI interface, you can program your Technotherm KS electric radiators hourly, daily and weekly to perfectly match your routine. This isn’t just a convenient way to keep your rooms comfortably heated when you need them; by zoning your heating, you can also save on your energy usage by heating unoccupied rooms less often or to a lower temperature.

Flexible Fitting
