Central Heating System Powerflush

Do you have radiators with cold spots, ones that take longer to heat up than others, ones that don’t heat up at all, or indeed a noisy boiler or pump? These are all signs that your system could potentially be full of sludge and you need a central heating system powerflush.

BEFORE A POWERFLUSH

  • Boiler kettling noise (‘kettling’ is a term used to describe noises that your boiler doesn’t usually or shouldn’t be making, such as banging, humming and so on).
  • Cold spots on radiators.
  • Noisy boiler.
  • Radiator slow to heat up.
  • Pump failure.
  • Poor flow.
  • Radiators hot at the top and cold at the bottom.
  • Pipes blocked.
  • Radiator valves stuck.

AFTER A POWERFLUSH

  • Boiler runs much quicker.
  • Radiators heat up quicker.
  • House becomes more efficient.
  • Reduced gas bills.
  • Increase in heat output.
  • Less costly repairs.
  • Increased system reliability.
  • Restoring good water flow.
  • Protection against future corrosion.

DURING A POWERFLUSH

I use a powerflush machine to remove sludge build up from within your central heating system. The machine sends water at high velocity around the system to dislodge the build-up of sludge and other debris. Cleaning chemicals are added to the system prior to the powerflush. This helps to break down stubborn sludge build up.

Depending on the age and type of system, I recommend having your radiators and pipework powerflushed prior to having a new boiler installed. When the flush is complete, the cleaning chemicals are drained and I flush everything out with fresh water. I will then restore your system, using a chemical inhibitor to protect the system from future corrosion.
