Over time oxygen in the heating system can react with the metals and components of a heating system such as radiators to produce magnetite (rust) particles, which becomes suspended in your system water. This process and the build-up of other chemicals (such as lime scale) can quickly cause blockages and damage key components within the boiler and system. To prevent this a process of thorough system flushing should take place when fitting a new boiler onto an old heating system. This process involves forcing old system water out of the heating system, whilst simultaneously filtering the system until all of the old water and contaminants are removed. Finally inhibitor and a system filter is added to prevent any future sludge and contaminants from building up.
We always run a system flush prior to installing your new boiler and this is included on the price you are given.
Is your heating system suffering from cold spots maybe your radiators are not warm enough? Then you could benefit from a power flush.
A power flush uses a big pump or magnet to flush water and cleaning chemicals through your heating system collecting and dissolving any trapped debris.
A power flush is not suitable for all properties, so we will happily attend for a free survey to discuss your heating requirements.
