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

Is it hanging on an exterior or interior wall?
At what height?
Have you measured the temperature in a different location?
The question is certainly valid.
Perform a hydraulic balancing instead of just adjusting the heating circuits randomly. Otherwise, you risk disrupting the entire hydraulic system, and the rooms won’t heat properly.
It’s also possible that the heating circuit pump cannot deliver the required flow rates.
Do you have individual room controllers? If so, disconnect them or open all of them, and then carry out the hydraulic balancing.

But maybe in the end it turns out to be easier to put an additional heater in the bathroomHe already did that with the wall-mounted heaters…What are the dimensions of the heating coils? Diameter and wall thickness? (Straws?)

The original poster has throttled the other rooms, yet they still warm up. The bathroom has a flow rate of 3 liters per minute in the underfloor heating circuit. That doesn’t sound like there isn’t enough flow available, does it?
I understood that the ERR (energy regulation valve) has already been fully opened by the original poster.

He has already done that with the wall heating…Yes, I also find it strange. With a design temperature of 35°C (95°F), it should actually work as mentioned.
