Central Heating Upgrades — Crondall, GU10
Magnetic-filter & power-flush specialists — local team covering GU10 and surrounding areas.
If your radiators are heating at the top but cold at the bottom in Crondall, that's classic sludge build-up — iron oxide settling in the bottom of each rad and blocking circulation. Fix is a power flush plus a magnetic filter retrofit and an inhibitor top-up. Costs roughly £450-£650 in GU10 depending on rad count. Common across older Tudor and Georgian cottages.
Why this matters in Crondall
Crondall customers most often ask about full-system replacements when the existing boiler is 12+ years old and the rads are running uneven — at that point a coordinated boiler+rads+cylinder job is usually cheaper than five years of patch repairs. Hart District Council planning permissions are only needed for unusual flue or condenser positions; we handle the paperwork either way.
Honest advice, even if it's "you don't need this".

Central Heating in Crondall — common questions
How can I tell if my Crondall system needs a power flush?+
Three signs: cold spots at the bottom of radiators, the magnetic filter coming out black after 3 months, or boiler kettling/banging during cycles. We do a free diagnostic visit in Crondall with thermal imaging and inhibitor test, then tell you honestly whether a flush, a filter retrofit or a chemical clean is the right answer.
My Crondall radiators heat at the top but stay cold at the bottom — what's wrong?+
Classic sludge build-up. The iron oxide settles in the bottom of each radiator and blocks circulation. Fix is a power flush + magnetic filter retrofit + inhibitor top-up. Costs roughly £450-£650 in Crondall depending on rad count, and gets you back to a properly hot system.
How long does a full central heating replacement take in Crondall?+
Boiler + cylinder + 8-10 radiators is typically 3-5 working days on site in Crondall, with heating and hot water restored every evening. Larger jobs with system redesign run 5-8 days. Realistic timeline given at the survey, not a "we'll be done by Friday" guess.
What heating controls do you recommend in Crondall?+
Hive and Nest 3rd-gen for most Crondall homes — proven, well-supported and easy for non-techy users. Tado smart radiator valves if you have one or two cold rooms. We stay away from cheaper brands that get pulled from the market in 3 years and brick your thermostat.
