Central heating is a really convenient thing to have installed, but once done it’s not just a matter of simply enjoying the warmth, as over time your system will become polluted with things like rust and general sludge, which form inside the pipework, boiler and radiators. If ignored this could cause several problems, so it is recommended that you give the entire central heating system a kind of clean out, (known as a power flush) on a regular basis.

Signs your central heating system needs a power flush

  1. The radiators are colder at the bottom than the top.
  2. There is unusual noise coming from the boiler, pump, or radiators.
  3. The radiators take longer than they should do to get warm.
  4. Although the pipes feel hot the radiators are not.
  5. If you ‘bleed’ a radiator no water comes out.
  6. Or you bleed a radiator and the water which discharges looks dirty.
  7. You notice the boiler tends to shut itself down for no reason.
  8. Some radiators feel okay, others cannot get to the required temperature.
  9. There are small leaks from one or more radiators.
  10. The water from your faucets is cloudy

There are several advantages from scheduling a regular power flush to eliminate the buildup of debris like limescale in the system, including:

  • A more efficient central heating system. Otherwise you may find some radiators are not working as well as others, or at worst, that none of them are producing the correct amount of heat.
  • Avoiding things building up the point where a blockage forms in any part of the central heating system, which can easily lead to some kind of damage and leave you with an expensive repair bill (as well as no heating!)
  • A regular power flush extends the life of your central heating system
  • Your radiators will not just heat up evenly they will do so much more quickly than a sluggish system can.
  • There won’t be any strange and potentially alarming noises coming from either the boiler or radiators.
  • You will have much hotter water.

More facts and tips on power flushing

Experts recommend that so long as you have your boiler serviced yearly you may only need a power flush around every five years – presuming that don’t experience any of the symptoms of potential problems outlined above. However, this is only an estimate as other factors can influence the need for a more frequent power flush.

For example, if you have a copper heat exchanger this is much more likely to erode and cause problems than a stainless steel heat exchanger will. It is also recommended that you plan a power flush before replacing your boiler with a new version to avoid carrying over any problems with existing sludge in the pipework or radiators.

It’s always worth investing some ash to have an expert power flush your central heating system, as they have the knowledge to work with the chemicals needed.
