Central Heating in Ash
Magnetic-filter & power-flush specialists — local team covering GU12 and surrounding areas.
Ash water is hard enough that central heating systems here suffer from limescale fouling on top of the usual magnetite sludge problem. A proper system clean here is a two-stage process — chemical descaler first to dissolve scale, then a magnetic flush to remove the freed sediment — not the single-stage flush some contractors call a power flush.
Why this matters in Ash
We see a lot of Ash heat exchanger failures driven by scale that's been silently accumulating because there's no scale reducer on the cold mains. Fitting a polyphosphate cartridge during a power flush adds £80 to the job and stops the same problem recurring on the next boiler.
Usually back to you the same working day across GU12.
Our central heating coverage of Ash extends right across GU12 and the surrounding parishes — Ash Vale (1mi north), Tongham (1mi south), Aldershot (2mi north-west). Guildford Borough Council is the planning authority for any external work like flue routing or condenser placement, and we deal with that paperwork end-to-end.

Central Heating in Ash — common questions
Will a power flush actually help if my Ash heating has limescale, not sludge?+
Only partially — a standard power flush is great for sludge but doesn't dissolve limescale. For Ash systems we do a two-stage clean: chemical descaler first (24-hour soak), then a magnetic flush. It costs more (typically £550-£700 vs £400 for a basic flush) but actually deals with both problems.
Will moving to a system boiler need a new cylinder in Ash?+
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 Worth doing properly rather than reusing an outdated cylinder.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 Ash 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.
Does my Ash system actually need a power flush?+
Only when the diagnosis says so. We check the magnetic filter, run a thermal imaging sweep across the rads, and test inhibitor levels before recommending. Many Ash systems just need a filter retrofit and a chemical clean — a third of the cost of a full flush. Common pattern in 3-bed semis along the railway line.
