Central Heating Power Flush

In and around the Chichester area

When is a Power Flush needed?

When hard water is heated, the natural minerals contained in the water break down into insoluble crystals which deposit out within water systems as a scale on the hottest surfaces. These are usually radiators, hot water cylinders and pipe work.

This scale not only restricts water flow, but acts as a very effective insulant, reducing heat transfer and efficiency. More fuel is required to heat the water and, in extreme cases, boilers may not be able to reach the designed operating temperature.

Heavy scale deposits can also lead to localized overheating, resulting in premature failure of heating appliances. Your heating system needs a power flush.

Benefits for your family:

  • A warmer home
  • Improved hot water
  • Fuel bills reduced by up to 50%

What is power flushing?
A power flush is a cleansing process which aims to remove deposits of sludge, rust and any other debris from your central heating system using a pressurized mix of water and chemicals. The contaminants, if left, can seriously affect the efficiency of a heating system and in severe cases a power flush is the only option available.

Why power flush?
Over a period of time your central heating system can become blocked and restrict the flow to your radiators making your system inefficient and more expensive to run. Power flushing can remove all these problems and restore the system to better circulation and efficiency and even help reduce energy bills.

Is it really required?
It is also boilers manufacturers requirement that the power flush process is carried out if you intend to connect a new boiler to an old heating system. This is because any contaminants already present in the heating system can quickly damage the internal pipe work of the new boiler.

Where does the rust in my heating system come from?
If you have seen someone else’s system powerflushed you will know what an amazing amount of stuff can come out, in all shapes and sizes. But, contrary to popular belief the vast majority of the sludge that you see does not come from your boiler. Most non-condensing boilers (those installed before 2006) have cast-iron heat exchangers and they, by and large, do not rust. The vast majority or rust and/or sludge in your heating comes from the radiators themselves as they are made from mild-steel.

How do I protect my heating system after it is cleaned?
Once you have had a specialist in to do the work for you, the best way of protecting your system is to have the heating system regularly topped upped with corrosion inhibitor. These stop the rust forming by adding a protective molecule to any exposed bare iron. That molecule (most often a form of another metal called molybdenum) parks in the place that the oxygen molecule would want to be. And the result is no rust. The only caveat to this is if your heating system has a design flaw in it and is pulling in fresh water all the time.
