Central Heating Upgrades — Alton, GU34
Magnetic-filter & power-flush specialists — local team covering GU34 and surrounding areas.
Alton central heating systems vary enormously — Georgian and Victorian terraces dominate but pipework, rads and controls can be anything from 1970s microbore to 2020s smart-zoned. We diagnose with thermal imaging and inhibitor tests before recommending a flush, upgrade or replacement. Many Alton systems just need a magnetic filter retrofit and a chemical clean — a third of the cost of a full flush.
Why this matters in Alton
Alton 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. East Hampshire District Council planning permissions are only needed for unusual flue or condenser positions; we handle the paperwork either way.
Covering Holybourne and Medstead too.

Most central heating jobs we do in Alton are for homeowners planning a long-term improvement: 12-year guarantees, smart controls, finance over 2-5 years. We design and price for that horizon, not a short-term cheapest-possible swap.

Central Heating in Alton — common questions
Do you fit unvented hot water cylinders in Alton?+
Yes — G3 qualified and we fit Megaflo, Telford and Joule cylinders regularly across Alton. Mains-pressure hot water on every tap, no loft tank, proper safety controls (T&P valve, expansion vessel, tundish, discharge route) fitted and certified. Reclaims the airing cupboard too.
Can you fit underfloor heating in a Alton extension?+
Yes — wet underfloor heating laid into screed for new extensions, or low-profile retro-fit systems for existing rooms. We coordinate with builders and tilers across Alton routinely, so it isn't a project you have to manage yourself. Particularly popular in 1930s and modern semis.
Can you upgrade radiators on a working Alton 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.
Will moving to a system boiler need a new cylinder in Alton?+
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.
