Heating problems
Heating bills went up: causes and what to do
If bills rose more than energy prices, the usual causes are a fouled heat exchanger, wrong settings or an unbalanced system. Maintenance and tuning often pay back within one season.

How to recognise it
What you see – and what it usually means
The boiler cycles on and off oftenwrong output or settings – tuning
High flow temperaturea condensing boiler is not condensing – tuning
Heat pump efficiency droppedfouled evaporator or filters – maintenance
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.
