Learn moreboiler repairs in Datchworth: questions we get a lot
Why has my heating stopped working?▾
Top causes: frozen condensate pipe in cold weather, low system pressure, a seized pump after summer dormancy, or a stuck motorised valve. Most are quick fixes once diagnosed properly.
Can I do anything before you arrive?▾
Check the boiler pressure (should be 1.0-1.5 bar cold). If it's below 0.5, top up using the filling loop. If you can hear the boiler firing but radiators stay cold, the issue is in the system, not the boiler itself.
Is it worth repairing an old boiler?▾
Honest answer: if it's over 12 years old and the repair is more than £400, replacement usually makes more financial sense. We'll lay out both options without pressure.
Do you guarantee repairs?▾
Yes — 12 months on the workmanship and any parts we supply.
