ᐅ Wall heating systems do not reach the desired temperature

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

Do the walls with the heating surfaces warm up evenly?
A reduction in pipe diameter naturally acts like a resistance.

What exactly is the through-flow cylinder? 🤨
I actually meant the valve 😀

Yes, the walls are noticeably warmer compared to the walls without heating.

What does the hydraulics of the entire system look like? You simply cannot go straight into the heating circuit valve with such a steep, high heating curve without the bathroom becoming unbearably hot.

What do you mean by hydraulics?
The builder advised me to increase the target room temperature by 1 degree.

Get rid of the heating engineer and reduce the bills!
