Power Flushing in New Malden

Systems in New Malden that serve Victorian and Edwardian terraces, larger 1930s and 1940s detached houses and flats near the station often carry years of accumulated sludge, and hard water in this area adds scale. A flush can bring them back to proper working order.

New Malden spans the boroughs of Kingston and Merton, with a busy High Street and a mix of terraces and larger interwar houses.

Over time, heating water breaks down the iron in radiators and pipes and creates a thick black sludge. It settles at the bottom of radiators and clogs pipes and the boiler. The result is cold patches, noisy running and a boiler that works harder than it should.

What it covers

  • Flushing the whole system radiator by radiator
  • Cleaning chemicals suited to the condition of the system
  • Testing flow and temperature after the flush
  • Fitting a magnetic system filter
  • Inhibitor added to protect against future corrosion
  • Flushing before a new boiler is fitted

When to call in New Malden

  • Radiators that are cold at the bottom or in the middle
  • A boiler that is noisy or keeps overheating
  • Black or brown water when you bleed a radiator
  • Heating that is slow to warm up
