In recent months, we have assumed that we would install an electric towel radiator (HTHK) with a heating cartridge in both bathrooms. Yesterday, we spoke with our heating installer for the first time. He said that the locations we had planned are very unfavorable. In the smaller bathroom, he anticipated problems with the towel radiator rusting. Essentially, he saw issues with having an electrical outlet in the splash zone. He had no concerns about towel radiators connected to our ground source heat pump, as the supply temperatures are relatively low. He mentioned that in summer, the supply temperature would be quite low, for example around 35°C (95°F), and higher in winter, for example around 45°C (113°F).
The entire house has underfloor heating.
Bathroom 1:
Towel radiator between the shower exit and bathtub
Bathroom 2:
Towel radiator opposite the shower
Now for my questions:
1. Can towel radiators be mounted upside down?
2. Is it possible to plug towel radiators (with appropriate wall penetration) into an electrical outlet in an adjacent room (utility room)?
3. Do towel radiators function properly at low supply temperatures?
4. Can towel radiators rust?
5. Are towel radiators necessary? The heating output from the underfloor heating surface is sufficient for both bathrooms. There is often talk about transition periods, but doesn’t my bathroom always maintain 23°C (73°F) when I set it to that?
6. Do towels dry adequately without a heating function?

Hello,
we have a 14m² (150 sq ft) bathroom with a towel radiator equipped with an electric heating element because the underfloor heating only reaches a maximum of 31°C (88°F) – even in winter when temperatures drop below freezing. So, what do you expect to achieve with such a low temperature in the radiator? It is actually even lower than body temperature! The electricity costs are also negligible when you use an intelligent control system.

What does body temperature have to do with this? Is your goal to heat the bathroom to 37.5 degrees? I think he means that a towel warmed to 30°C (86°F) doesn’t feel warm on the skin after a 36°C (97°F) shower.
