System restoration

Central heating power flush in Radstock

Radstock's ex-mining terraces are packed with 40-year-old open-vent systems. The pipes are fine; the water inside them isn't. A proper flush restores flow to cold-topped radiators and gives a new boiler a fair chance.

For: BA3 homeowners with a sludgy system

Why BA3 systems tend to be worse

Long-life terraced systems that were rarely refilled or protected accumulate more iron oxide than newer housing stock. It's not a criticism of the homeowner — it's just the age of the property.

Included in the flush

  • Each radiator flushed individually with magnetic capture
  • Boiler isolated and protected during the flush
  • Inhibitor dosed to manufacturer spec
  • Permanent magnetic filter fitted as standard
  • Photo report of water samples before and after

Frequently asked

Do I need it before a new boiler?
Yes — most manufacturers require a documented flush and filter fit to honour the guarantee.
How long does it take?
A full day for a 3-bed terrace. Larger homes with more radiators take a day and a half.
Will it fix cold radiators forever?
It fixes the sludge cause. If the pipework is 8mm microbore that's already been sludged and cleared multiple times, the honest fix is targeted repipe.
