Product Details

The under tile heating mats come in a range of sizes to suit all bathrooms, and two different sizes for the in-shower heating mats ensure the right fit for your shower. The mesh of both mats can be cut to allow flexible installation around fixtures, drains and differently shaped bathrooms. However, the heating element must not be cut in any case. Therefore please ensure to choose the right size of mat.

1. What colour is the controller available in?

The RTF-TC controller is only available in white.

2. How long does it take for the floor to heat up?

Approximately 20-30 minutes, however, this will be dependent on how the mat is installed and the type of tiles.

3. Can you program the under tile heating mat to come on at different times?

Yes, the RTF-TC controller can be programmed to alternate between the ECO and COMFORT temperatures via a 7 day/24 hour program.

4. Can the FTM be installed inside walls?

No, it is designed for under tiles only.

5. Is STIEBEL's under tile heating classed as ambient heating?

Yes, it is designed to make the floor comfortable to walk on. It is not designed as the main source of heating for the bathroom.

6. When you have an in-shower mat and under tile heating mat, do they operate with the same controller?

Yes, the controller operates both mats to a maximum of 2.3 kW in total.

7. How long is the cable from the mat to the controller?

The black cable at the end of the under tile heating wire is 4 metres long.

8. Can the FTM be installed under wood or vinyl?

No, the FTM mat is recommended for installation under tiles or polished concrete only.

9. Can only an in-shower mat (FTB) be installed?

Yes, but it would be unlikely to be requested. Therefore, the RTF-TC controller (which usually comes with the FTM installation kit) has to be ordered separately.

10. If I have a double shower (approx. 1500 mm x 900 mm) what size in-shower heating mat do I need?

Two of the FTB 140 (0.7 m2) in-shower heating mats would be required.
