shift that sludge
Over time sludge and deposits can build up in your central heating system causing it to become inefficient and more expensive to run. The solution is to get the system flushed and treated by a qualified heating engineer.
If you're installing a new boiler in an existing system we recommend having your system flushed as part of the installation this will prolong the life of your boiler.
how will I know if my system needs cleaning?
If you are experiencing any of the signs below, you should contact a heating engineer for a full assessment.
- A reduction in the overall heat
- Your heating takes longer to heat up
- Cold spots in the system
- Poor circulation
- Excessive noise
- Blockages in the system
- Increases in your bills
- Dirty water in the system
why do systems need cleaning?
Black oxide sludge (magnetite) can build up in heating systems as a result of electrolytic corrosion and this reduces heat transfer efficiency. Limescale deposits can also result in efficiency loss.
how is the system cleaned?
To do the job properly a heating engineer will powerflush the system with a mechanised pump using a combination of mains water and a specialised cleanser.
how long should this take?
For a basic system flush which does the whole system in one go it will take approximately 2-3 hours. For a more thorough system flush you could choose a power flush this will take about 1 day and each radiator will be cleaned individually using a high powered pump.
Remember, cleaning alone will not solve the problem. It is important that the system is also treated with a chemical inhibitor to prevent future corrosion.
