Central Heating Power Flush in Aldershot
If your Aldershot radiators are cold at the bottom, sludgy in the pipework or slow to warm up, a power flush is often the fix — but not always. We diagnose first with a magnetic filter check and a thermal imaging sweep, and only recommend a flush when the system genuinely needs one. A third of the Aldershot homes we visit just need a chemical clean and a magnetic filter fitting — a third of the cost of a full flush.
Why this matters in Aldershot (GU11)
Aldershot water is moderate, so sludge tends to come from radiator corrosion rather than scale. Older Victorian/Edwardian terraces near North Town on their second or third boiler are the most common flush candidates in GU11.

Power flush FAQs for Aldershot
How much does a power flush cost in Aldershot?+
£395 for a small system (up to 6 radiators), £495-£550 for a typical 8-10 radiator family home, £595-£650 for larger systems. Includes chemical inhibitor, magnetic filter fit, and a written before/after report with thermal images.
How do I know my Aldershot system actually needs a flush?+
Signs: cold at radiator bottoms, black sludge in filter, banging or bubbling noises, slow warm-up, boiler tripping on high return temperature. We diagnose free at survey — if a chemical clean will do, we'll say so and save you £250.
How long does a power flush take in Aldershot?+
A day for a typical 8-10 radiator Victorian/Edwardian terraces near North Town. Larger or unusually dirty systems occasionally run to 1.5 days. Heating and hot water restored end of the day.
Will a power flush damage old Aldershot radiators?+
Very old radiators (30+ years) with existing pinhole corrosion can leak after a flush — the flush doesn't cause it, but it does reveal it. We inspect for age and thin spots at survey and flag anything at risk before starting.
Do you always fit a magnetic filter after a Aldershot flush?+
Yes — Adey MagnaClean Professional 2 fitted as standard on every flush. Catches iron oxide before it re-contaminates the boiler and voids the manufacturer warranty. Not optional.
