heating upgrades in Broxbourne: questions we get a lot

Where do boiler leaks usually come from?

Most common: pressure relief valve discharging because system pressure is too high, a perished pump seal, or a failing heat exchanger on older units. We diagnose properly rather than guess.

Should I turn the boiler off?

If water is actively dripping and you can see it pooling, yes — switch the boiler off at the spur, and turn the system pressure down via the filling loop if you can. Then call us.

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.

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.
