About Church Langley

Modern estate built in the 1990s/2000s — predominantly combi-boilered family housing now reaching first major service intervals.

Predominantly 1950s–70s post-war housing with a mix of terraces, semis, and 60s-built flats. Pockets of older stock around Old Harlow.

  • Original 1960s flats often have undersized gas supply pipes that limit modern combi performance
  • Older Old Harlow properties frequently have low mains water pressure that affects combi choice
  • Many 60s/70s back boilers still in service — our regular work involves removing these and reinstating fireplaces

  • Smart thermostat brand-agnostic — Hive, Nest, Tado, Honeywell, Drayton

Frequently asked questions — heating upgrades, Church Langley

Is it dangerous to keep topping up?

Not immediately — but the cause needs finding. Repeated top-ups mean fresh oxygenated water keeps entering the system, which corrodes radiators and pumps from the inside.

Where do hidden leaks usually hide?

Pressure relief valve discharging outside, perished pump seals, pinhole leaks at radiator valves, or a failing expansion vessel. Each one has a different fix.

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.

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.
