Underfloor heating in the bathroom sufficient or additional heating - wall heating?

I have already written this elsewhere: I think this towel heater is the biggest bad investment in our house. It takes quite a long time for the towel warmer to get hot and it is not suitable for "spontaneous" showering/bathing with a warm towel. You should have it turned on half an hour in advance.

I also don’t understand why anyone would want to dry wet towels with it. The bath towels are dry again by the next use, and we have a small towel for each family member so that no one has to use a wet towel.

However, you could heat with our towel heater. The thing heats up properly (unfortunately it can only be turned on or off, no regulation). But as I said, you would have to turn on the heater half an hour earlier or install a timer.

In winter (we moved in February) we managed well with the underfloor heating. It is set to warm up the rooms from 5:30 am and they are warm when I go to the bathroom at 6:00 am.

I do admit, however, that I have the thermostat in the bathroom set to level 5 (optimal: 4) because I like it warm there, and thus it is warmer in the bathroom than in the rest of the house. During the transitional period, it was also always sufficiently warm in the bathroom in the mornings.

Connecting towel rails or other radiators to underfloor heating makes no sense. Underfloor heating usually runs at about 32° Celsius supply temperature. A radiator with about 65° - that doesn't match. A towel rail on a 32° underfloor heating will not dry anything because it will only become lukewarm. So, if you want a towel rail, it should be electric and only turned on when needed. The few kWh won't make you poor.

Hello,
we (new building 2012) also had the problem that in our 15sqm bathroom a considerable part of the underfloor heating was lost, namely due to the bathtub and, caused by the drain, half of a large walk-in shower area. The bathroom has a northeast orientation. The underfloor heating was already laid tightly - but the heating surface is still almost too small if the temperature demands of the female faction have to be satisfied.
Unfortunately, 21 degrees seem to be too little. So we installed a visually nice (a bit more expensive than the simple models) infrared heater above the bathroom door (directly opposite the shower area) and the problem was solved. The device also has a timer function - so no one forgets to switch it off in the morning. This quickly achieves a short-term temperature increase of 3 degrees or more.
In normal everyday life without showering/bathing, 21 degrees are sufficient.
The solution cost less than €400 and seems very effective to me, as the heating-up occurs immediately. And generally increasing the flow temperature (throughout the whole house) and throttling all rooms except the bathroom is certainly the wrong and in the long term expensive path.
Best regards

Hello,

....we (new build 2012) also had the problem that in our 15sqm bathroom quite a bit of underfloor heating was lost, namely due to the bathtub and, caused by the drain, half of a large barrier-free shower area....

Therefore, with a proper and precise overall planning of the system, inactive heating surfaces as well as those with reduced output are taken into account during the heating surface design, which is especially important with heat pump systems.

Correct!

I think the 2nd option is the most practical, I believe.

Hello,

I wanted to chime in on this occasion.
I heard there are also towel warmers connected to the underfloor heating and additionally have an electric heating element inside? Is something like that sensible?

Our heating engineer said he would connect a suitably large towel radiator to the underfloor heating and reduce the installation spacing in the bathroom (10 cm). The towel radiator is intended to compensate for the lost heating surface from the shower and bathtub.

We like it cozy warm for bathing or showering, should we possibly also add a pure electric heater? Or maybe one of those infrared panels?
