Heating problems
Underfloor heating heats unevenly: causes and what to do
When some rooms are warm and others cool, the loop flows are usually not matched or the loops are fouled. It is fixed by balancing and flushing – without lifting floors.

Likely causes and the right service
You can safely check
- Check the pressure gauge (usually 1–2 bar for a cold system – see the manual).
- Check that radiator thermostatic heads and manifold valves are open.
- Note the error code and photograph the rating plate.
We do not give repair instructions: gas, electrical and pressurised systems are serviced by qualified specialists.
Smell gas? Do not switch anything electrical, close the gas valve if safe, open windows, leave and call 112.
