To put it simply, Yes there is.
The clue is in the name, a chemical flush is carried out using chemicals and a magnetic filter. A power flush uses a pump and a magnet to clear sludge from the system.
Despite there being differences between a chemical and a power flush, they Serve the same purpose. Whenever a flush is carried out its sole purpose is to remove debris from the heating system to enable it to work more effectively and efficiently. Over time corrosion can lead to rust forming within your heating system. Once rust and debris have started to form/gather in the system it is carried around and can lead to multiple issues such as cold spots in radiators and problems with the heat exchanger amongst others. Faults such as these mean your heating will not be working effectively and can be rectified by carrying out a flush.
A chemical flush is often carried out when there is a small amount of sludge to remove from the system, or on newer systems where there hasn’t been time for a lot of sludge to build up. The chemicals are added to the system via a magnetic filter. These are then carried around the system by the boiler. Once they have cycled around the full system the chemicals are flushed out and an inhibitor is added to the system to maintain the results of the flush. Whereas for a Power flush a pump will be used to move chemicals around the system and a magnet will gather the debris, but of course, you knew that from reading our last blog.
A chemical flush will often be lower in cost than a power flush due to the difference in the labour involved and the costs of chemicals versus the running of the pump. However, that should not be a deciding factor when you are deciding what flush to get. The best flush for your system will depend on the severity of the build-up in the system, each system should be assessed on a case-by-case basis.
Should you have any questions or if you are wondering whether your system would benefit from a flush either power or chemical, please get in touch and we will do our best to advise you.
