Learn moreLocal, honest heating upgrades for Datchworth homes
We've been doing heating upgrades in Hertford long enough to know which streets have shared chimneys, which estates have undersized gas supplies, and which boilers tend to fail first.
That experience means we get the spec right at the survey, not halfway through the install.
And we don't cut corners on the bits you can't see — proper pipework, magnetic filter, full system flush where needed.

Frequently asked questions — heating upgrades, Datchworth
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.
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.
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.
