    Technotherm infrared heating panels can be installed DIY with ease, without the need for costly professional callouts. The panels can be either wall or ceiling mounted both horizontally and vertically to suit your needs – simply plugging into the nearest available wall socket. 

    These products come with an IP44 rating, which renders them safe for use in bathroom zones 2 and 3. Any electric appliances intended for bathroom use must be hardwired to the wall by a professional electrician: this is not a DIY job. Always defer to the manufacturer’s guidelines regarding the bathroom suitability of any product.

    Technotherm infrared panels come with in-built RF receivers that allow wireless control using the TPF-Eco Radio Frequency Thermostat, which can control a maximum of 9 panels. Technotherm infrared panels are designed for use with the TPF-Eco, allowing nuanced temperature control and 24/7 programming. To access your heating on the move, you can purchase your panels with the Eco Interface, which works in conjunction with the TPF-Eco for on-demand temperature management from anywhere in the world using a smartphone or tablet.

  • Warranty
    Technotherm ISP Frameless Infrared Heating Panels come with a 5 Year Warranty on the heater body and a 2 Year Warranty on the thermostat and receiver.

  • What You Will Need

Redefine interior space heating with Technotherm ISP Frameless infrared panels, offering a discreet, low-key heat source with an emphasis on efficiency and elegance. Manufactured to exceptional standards, the Technotherm ISP frameless range boasts a slimline housing that adds a modern touch to any room. This 350w version of the Technotherm ISP Frameless infrared heating panel is the smallest in the range, with a reduced height of 400mm to fit on narrow stretches of wall. The panel can even be wall or ceiling mounted to suit your needs and help maximise space in smaller rooms.

German-made, with rock wool insulation to prevent heat loss from the rear, Technotherm ISP infrared panels use carbon wiring stitched into a Matrix Heat Mat to uniformly heat the front surface of the panel, which then radiates heat out into the room to warm your spaces. This heat conductive mat manages to house up to ten-times more wire than conventional methods, helping to provide an even distribution of heat, without hot or cold spots.

Technotherm are so passionate about the construction of their infrared panels 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 panel at each stage of development.

Discreet, efficient, and suitable for easy DIY installation, Technotherm infrared panels come with integrated RF receivers that communicate with the TPF-Eco Radio Frequency Thermostat for full heating control. This means, unlike competing infrared products, Technotherm infrared panels are ready for use from the second you open the box, without the need for professional callouts or additional wiring. Simply mount them on the wall, plug them into the nearest socket, and you’re good to go.

Controlling your Technotherm Panels

Technotherm Infrared Panels work in tandem with the TPF-Eco Radio Frequency Thermostat. Using the thermostat, you can create a detailed 24/7 heating schedule that caters to your every whim, helping you save energy by specifying exactly when, and to what extent, your rooms are heated. Using multiple thermostats, you can also zone your heating and assign different heating schedules to different areas of your home. An essential component of your heating system, the TPF-Eco must be purchased alongside your panels to unlock their full potential.

To adjust your heating using WiFi, you can purchase your panels with the Eco Interface Internet Heating Controller. The Eco Interface plugs directly into your home router, allowing you to make alterations to your heating via WiFi using a smartphone or tablet. The Eco Interface must be used in conjunction with the TPF-Eco and both devices need to be purchased for WiFi control. Further information can be found in the user guide under the installation tab.
