Are your radiators not working properly? Or do you have a noisy boiler or central heating system? If you have either of these things, the chances are that you have a build-up of air, rust or limescale in your heating system.
You might be able to solve these issues by bleeding your radiators. But if this doesn’t solve the problem, you might need a boiler engineer to power flush your pipes.
Read on to learn more about central heating power flushing and whether your central heating system might need it.
What’s a power flush?
A power flush cleans your central heating system by forcing out any debris that has collected in your pipes or radiators over time. This debris could include rust, sludge or limescale. Power flushing is usually very effective and can help to prevent boiler breakdowns.
When could my central heating system need power flushing?
We’ve already talked about a few instances when your central heating system might need power flushing. Power flushing might be necessary if you have:
- Radiators that heat up slowly or don’t heat up properly
- Radiators that let out discoloured water when you bleed them
- A noisy boiler
- Noisy heating pipes
You also might need a system power flush if you’re installing a new boiler. Most boiler manufacturers recommend that you flush your system before fitting your new boiler and this might be a condition included in the warranty.
How does power flushing work?
There are 4 stages to power flushing:
- Firstly, the heating engineer will connect a pump to your central heating system
- Secondly, a cleaning solution is channelled through the system to remove any debris
- A rust inhibitor is then pushed into the system to help avoid further build-up
- Finally, your engineer will flush your system with clean water. They’ll test a sample of the water to make sure that there is no acid left in the system
An average power flushing service should take between 4 and 6 hours to complete, but this can vary depending on the size of your central heating system and how much debris it’s collected.
Who can do a power flush?
Power flushing is not a DIY job. You should always use a qualified boiler engineer to carry out a power flush. When choosing an engineer, make sure you check their credentials and any online reviews they might have.
