ᐅ Is an additional heater recommended in a bathroom with underfloor heating?

Hello everyone,
We are currently planning our new house and have reached the point where we need to decide on an additional fast heating option for our bathroom, one that responds more quickly than the rather slow underfloor heating.
We are considering either a wall-mounted fan heater or an electric towel warmer. We understand that both options have their advantages and disadvantages, but this supplementary heater will only be used during transitional seasons when the underfloor heating is not yet running or has already been turned off.
The bathroom has a floor area of about 18 square meters (living area around 16 square meters (172 square feet) due to the sloping ceiling). The built-in heating system will be an air-to-water heat pump with a controlled ventilation system.
Personally, I’m leaning toward the towel warmer, mostly for aesthetic reasons.
What would you recommend?
Best regards,
Dirk

nordanney30 Jul 2013 14:48We are getting a 500-liter (130-gallon) water storage tank (filled with “heating water” as a supplement to our ground source heat pump), which will provide hot water through a heat exchanger (with four women in the household, we need a lot of shower water that a combi boiler cannot supply). At the same time, this water storage tank will serve, via a second heating circuit, to heat the bathroom (of course, underfloor heating). This second heating circuit can operate independently from the heat pump and supply warm floors to the bathrooms, for example, in spring and autumn.
Conclusion for us: No additional heating is needed; we consider towel warmers just an expensive luxury.

Hello,
I want to bring this thread back to attention.
What is actually recommended now? We are getting an air source heat pump with low-temperature heating circuits. The entire house will be equipped with underfloor heating. In the bathrooms, the heating pipes will be laid closer together at 7cm (3 inches).
Our heating installer also said that he would connect a towel radiator to the underfloor heating to help bring the bathroom up to temperature. Basically, as an additional "external" heating surface alongside the underfloor heating area in the bathroom.
Is this sensible? If not, what should be done instead?

in addition to underfloor heating, we decided to install a towel radiator heated by an electric heating element.
Since we have now been living in the house for almost eight weeks, we have been able to gather some initial experience.
Our bathroom is warm even without the towel radiator, but by now we don’t want to do without warm towels anymore.
Personally, I don’t think connecting the towel radiator to the underfloor heating is ideal, since it is only circulated with "normal" heating water at about 28 - 37°C (82 - 99°F), depending on the setting.
The electric heating element can reach other temperatures...
Therefore, I can fully recommend our solution.
Kind regards,
Dirk

Thanks for your reply, Dirk.
If the bathroom is warm even without the towel radiator, that’s already a good sign. We currently don’t have warm towels either, but I remember from my childhood that towels were often placed over the regular radiator. However, that’s not a "must" for me. I just want a warm, cozy bathroom.
What kind of heating system do you have? Also an air-to-water heat pump?

Doc.Schnaggls24 Apr 2015 13:57Hello,
yes, we have an air-to-water heat pump (Tecalor 403 SOL) with controlled residential ventilation and heat recovery. What a confusing mix of abbreviations...
When the system was commissioned in February, outdoor temperatures were as low as -20°C (–4°F). The technician from Stiebel Eltron (parent company of Tecalor) set the flow temperature to 32°C (90°F) and explained that if it gets too warm, we should reduce it by 0.5°C (0.9°F) increments every two days.
We quickly reached a flow temperature of 27°C (81°F) – which is comfortable for us now.

Dirk

We have the LWZ 403 SOL as well – the same air-to-water heat pump. Without the electric towel radiator, our bathroom wouldn’t work. Why? Our bathroom is very small, with both a shower and bathtub that include cutouts—so there’s hardly any heated floor surface. That’s why a towel radiator was essential for us, and in winter it regularly runs before the kids take their baths...
So it really depends on your bathroom.
