Common questions about heating upgrades in High Cross

How often should I need to top up?

A healthy sealed system should hold pressure for 6-12 months between top-ups. Anything more frequent points to a leak.

Could it be the expansion vessel?

Yes — a perished expansion vessel inside the boiler is a common cause. We test the vessel as part of diagnosis.

How much does a power flush cost?

Typically £450–£750 depending on system size and number of radiators. We give a fixed price after a quick survey.

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.
