There are several signs that your system could benefit from a power-flush, including:
- Cold areas at the bottom of radiators
- Excessive noise from the boiler or radiators
- Some radiators do not heat as well as others
- Radiators struggle to heat up, even though the pipework gets hot
- Bleeding the radiators produces discoloured water
- The boiler frequently shuts down and needs to be restarted
A power-flush clears away any sediment and sludge that has built up within your pipework and radiators so your central heating system can work as efficiently as possible. An engineer will connect a pump to your system and will push chemicals through the pipework that break down and remove any build-up. At the end of the process, a corrosion inhibitor will be added to your central heating system in order to prevent rust from forming in the future.
Prepare for a new installation
It makes sense to clean out your pipework and radiators to sure that your home is ready for the installation of your new boiler. Otherwise, any sediment that has built up within the system could end up damaging or reducing the efficiency of your new boiler.
Removing all the sediment from your system allows it to heat up quicker, to heat up more evenly, and to reach hotter temperatures. The more efficient your system is, the more money you’ll save on running costs
You should see the benefits of a power-flush for a long time. As long as you regularly maintain your boiler and central heating system so that you stay on top of any issues in future, a power-flush should have a lasting impact.
