Horsell Heating System Specialists
Magnetic-filter & power-flush specialists — local team covering GU21 and surrounding areas.
For Horsell customers thinking about underfloor heating in an extension, we coordinate with builders and tilers across GU21 routinely — wet UFH laid into screed for new builds, low-profile retro-fit for existing rooms. Not a project you have to manage yourself.
Why this matters in Horsell
Horsell central heating systems are mostly serving Edwardian villas near the common, where the common pattern is a 10-20 year old combi or system boiler, original microbore or 15mm pipework, and rads from anywhere between 1970 and 2010. The single best £200 you can spend on this kind of system is a magnetic filter retrofit — it doesn't fix existing sludge but it stops the slide getting worse.
Itemised in writing — the price we quote is the price you pay.

Central Heating in Horsell — common questions
How can I tell if my Horsell 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 Horsell 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 Horsell 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 Horsell depending on rad count, and gets you back to a properly hot system.
Will moving to a system boiler need a new cylinder in Horsell?+
Almost always. The old G3-unsafe vented cylinder gets replaced with a modern unvented one (typically 180-210L), the loft tanks come out, and the airing cupboard is reclaimed. Worth doing properly rather than reusing an outdated cylinder.
Can you upgrade radiators on a working Horsell heating system?+
Yes — we isolate, drain just the affected circuit and swap radiators in a half-day to a day depending on quantity. The rest of the house stays in use. Useful when you only want larger rads in the lounge or bedroom rather than a full system change.
