Central Heating in Guildford
Magnetic-filter & power-flush specialists — local team covering GU1, GU2, GU3, GU4, GU5 and surrounding areas.
Guildford water turns central heating sludge from a slow background problem into a fast one. We power-flush more Guildford systems than anywhere else we cover, and almost every one shows the same picture: sediment in the bottom of every radiator, a magnetic filter that's never been fitted, and a system that's lost 15-25% of its heat output without anyone noticing.
Why this matters in Guildford
Stoughton and Burpham older properties especially suffer because pre-2005 copper systems combined with Guildford water and no inhibitor produce magnetite sludge fast. A power flush plus a permanent magnetic filter retrofit on these homes typically extends boiler life by 5-7 years and recovers measurable heat output by the first winter.

Central Heating in Guildford — common questions
How can I tell if my Guildford heating system is sludged up?+
Telltale signs: radiators warm at the top but cold at the bottom, one radiator that won't heat up no matter how often you bleed it, a magnetic filter that fills with black sludge between services, or the boiler making rumbling noises. Any of these on a Guildford property usually means a power flush is overdue.
Will moving to a system boiler need a new cylinder in Guildford?+
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 Worth doing properly rather than reusing an outdated cylinder.
Do you fit unvented hot water cylinders in Guildford?+
Yes — G3 qualified and we fit Megaflo, Telford and Joule cylinders weekly across Guildford. Mains-pressure hot water on every tap, no loft tank, and proper safety controls fitted and certified.
Can you fit underfloor heating in a Guildford 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 Guildford routinely, so it isn't a project you have to manage yourself. Particularly popular in modern townhouses near the station.
Hard-water-aware power flushes, magnetic filter retrofits and radiator upgrades across Guildford and the GU1-GU5 villages. Gas Safe registered, thermal imaging used for honest diagnosis, fixed pricing.
