Boiler Installation in Ash
Worcester Bosch Accredited Installer — local team covering GU12 and surrounding areas.
Ash and Ash Vale sit in one of the harder-water pockets along the GU12 border, and we treat every boiler install here with limescale protection in mind from the survey onward. A modern Worcester Bosch heat exchanger will scale up far faster on Ash water than on Farnborough's, and we add the protection that keeps the manufacturer guarantee enforceable.
Why this matters in Ash
A lot of Ash properties have galvanised steel cold mains heading into the boiler — fine until you fit a higher-efficiency unit that's more sensitive to debris. We fit a flushable strainer on the cold inlet during install on most Ash jobs as cheap insurance against a £700 heat-exchanger callout six months in.
Honest advice, even if it's "you don't need this".

Boiler Installations in Ash — common questions
What hard-water protection do you fit on Ash boiler installs?+
Two things as standard: a polyphosphate scale-reducer cartridge on the cold inlet to the boiler, and a magnetic system filter (typically a Magnaclean Pro or Adey Pro2) on the return. Together they keep the Worcester Bosch heat exchanger clean enough for the full 10-12 year guarantee.
How long is the guarantee on a Worcester Bosch boiler in Ash?+
10-12 years parts and labour on the Greenstar i and Greenstar 8000 range when installed by us as an Accredited Installer — that's longer than most national chains will quote and is backed directly by Worcester Bosch, not by us.
Will hard water affect a new boiler in Ash?+
Ash sits in a very hard water zone. We fit a scale reducer on the cold mains and a magnetic system filter as standard on every install — this protects the Worcester Bosch heat exchanger and keeps the 12-year guarantee valid in practice, not just on paper.
Are you Gas Safe registered for installs around GU12?+
Yes — Gas Safe registration number 554328, and Worcester Bosch Accredited Installer status which is what unlocks the 10-12 year manufacturer guarantees. You can verify both registrations independently before we start work.
