Common questions about heating upgrades in High Cross
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.
Will a smart thermostat actually save money?▾
Yes — typically 8–12% off heating bills if you use the scheduling and zone features properly. Hive and Nest both pay back inside two years for most households.
Do I really need a power flush?▾
If radiators have cold patches, your boiler is noisy, or you're fitting a new boiler to an older system, yes. Otherwise a chemical flush and magnetic filter is often enough.
