Across Ireland there are thousands of homes with central heating systems that have become very inefficient. The accumulation of black iron oxide in a system that manifests itself as black sludge, this can result in many problems that can be very expensive to put right if left untreated,
Cold radiators – If your radiators are cold at the bottom but hot at the top this indicates sludge build up in your system. This is caused by a build-up of iron oxide sludge at the bottom of your radiator (as the sludge is heavier than water) which results in a restriction of the flow of water.
Sludge and scale – Black Oxide sludge forms continuously in all unprotected central heating systems as a result of corrosion. It will also harden into scale on the hottest surfaces of a system (i.e the boiler heat exchanger causing it to make knocking and kettling noises). This also prohibits efficient heat transfer.
What is a Power Flush ?
A power flush is an effective technique to keep your radiators working efficiently. During a power flush, water and cleaning chemicals are pumped through your radiators at a high pressure which flushes out any build-up and dirt that is causing a blockage within your heating system.
As well as removing sludge, power flushing we will add special inhibitors to your system to prevent future corrosion within it. After flushing your heating system you will feel heat effectively circulating around every radiator in your home ( If too much sludge hasn’t completely blocked the radiators and pipe work ). Your central heating system will operate more efficiently, which will in turn save you money on your heating bills and also save you the time and money spent on central heating repairs.
Power flushing can take from as little as four hours, depending on how much sludge is in your system and how many radiators you have.
How do I know if I need my heating system power flushed ?
Well’ here’s a number of symptoms to look out for:
- Boiler switching on and off frequently.
- Boiler constantly breaking down.
- Boiler making banging and/or knocking noises.
- Central heating radiators taking a long time to heat up.
- Cold spots on radiators.
- Radiators not getting very hot when the pipe work is getting hot.
- House always feels cold even when the heating is up to max.
- Boiler making a “kettling” noise (like a kettle boiling).
What benefits can I expect after power flushing?
There’s many benefits to power flushing your central heating:
- Faster radiator heating up time.
- All radiators produce more heat.
- Boiler runs quieter.
- Overall central heating system quieter.
- A lot less cold spots on radiators.
- Cheaper gas bills.
- Better hot water temperatures.
- Less risk of breakdown.
More reliable and efficient central heating system, giving you a warmer house at less cost.
