Hello everyone,
I need your help. We have the problem that we can’t get our bathroom properly warm. Due to the small underfloor heating area in the bathroom, three additional wall heaters were installed. Still, we can’t get the temperature above about 21 degrees Celsius (70°F). The calculation was based on 24 degrees Celsius (75°F). I have already switched off the EER and set the flow rate to the maximum (3 liters per minute). All other rooms easily reach their target temperature and are sometimes already at the minimum flow rate.
Do you have any other ideas on what could be done?
Thank you very much and best regards

I set the heating curve to 0.4 in our house to reach 23°C (73°F) in the bathroom. However, we do not have wall heating. Shift 0, comfort setpoint 23°C (73°F).
When I increase the comfort setpoint to 25°C (77°F), a heating curve of 0.26 is sufficient.
The supply temperature is just under 30°C (86°F) at about 1-2 degrees (1.8-3.6°F).

128 m² (1,377 ft²) house built according to the 2016 energy-saving regulations. Thanks a lot. Those are similar values. I’m currently testing if the bathroom has the correct valve; after that, I’ll try your settings.

The feedback from the builder was that I should increase the room target temperature by 1 degree. But that’s not how the design was calculated.

Sorry, but 0.4 in a new build is beyond all reason!
You’ve also been adjusting the heating for weeks now. You’ve tried everything from 0.1 to 0.3 already. And now even 0.4. 😳 Well, it really depends on the circumstances. The energy-saving regulations are not the same as KfW 40.
I’m also following energy-saving regulations and have 0.35 at a target room temperature of 21.5°C (70.7°F). And that’s not ruining me financially.
I also have a basement that’s part of the thermal envelope but currently unheated, which affects the supply and return temperatures.
