Hi,
I have already read a few threads, but I still have a question.
We are getting a guest toilet in our new home, and we are adding a shower to it. The guest toilet will have about 3 square meters (32 square feet) of floor space and will have underfloor heating (like all rooms). According to the construction company, because of the shower, we now have to install a towel radiator. I assume this is related to the heat demand calculation. But is that really the case? Can they require this, or can I insist that the underfloor heating in the small bathroom is just laid more densely? It is also not yet decided whether the radiator will be electric or connected to the underfloor heating system. The latter doesn’t seem to make much sense either.
Best regards
Sebastian

Peanuts7415 Jan 2016 10:11It is absolutely not true that a (reasonably large) towel radiator does not contribute to heating the room. On the highest setting, the radiator (electric) becomes really warm to hot and does so very quickly. Even in our bathroom of about 15m² (160 ft²), you can clearly feel the difference when it is turned on or off. In winter, we switch it on about 30 to 60 minutes before showering, and as mentioned, you can definitely notice it, with the towels coming out almost as if they had been pressed in a heated mangle (if anyone still knows what that is).

Towel warmers cannot replace a heater; they only warm the towel, as the name suggests.@ypg
I’m afraid I have to disagree with you on that.
At the very beginning, we once forgot to turn off our towel radiator in the main bathroom after showering in the evening.
The next morning, the temperature in the fairly large bathroom was just over 29°C (84°F).
A properly sized towel radiator can definitely also be used effectively for additional heating.

No, we have an air-to-water heat pump from Tecalor.
The heat pump alone easily heats the bathroom to 23°C (73°F) with a current flow temperature of 27°C (81°F).
We only reached 29°C (84°F) because our (electric) towel warmer was accidentally left on all night.

Do you have gas? With a heat pump, it wouldn’t be possible to achieve that with a supply temperature well below 30°C (86°F)... Doc.Schnaggls schrieb:

Dirk At what outside temperature do you achieve a supply temperature of 27°C (81°F)?

Doc.Schnaggls15 Jan 2016 10:56Last year, in January and February, we gradually lowered the supply temperature from the initial 29°C (set by the commissioning installer) to the current 27°C.
The adjustments were made in increments of 0.5°C, with intervals of three to five days between each change, as explained by the installer, because the originally set supply temperature made the house noticeably too warm (up to 26°C).
Since then, we have been satisfied with this setting even at outdoor temperatures down to -15°C (5°F).
If it occasionally felt too cool, we compensated with our soapstone stove on the ground floor. Thanks to a fairly open layout and controlled mechanical ventilation, the stove’s warmth reliably spread throughout both the ground and upper floors.

Dirk
