ABOUT THE PROBLEM
Cleaning a central heating system is integral to its health and powerflushing is a popular cleaning method due to the rapid but comprehensive clean it delivers. The benefits of a clean heating system are well-documented:
- more even heat distribution throughout the property
- improved overall energy savings
- lower household bills
- increased system reliability
- extended system life
So how do you know if a system needs a powerflush?
Here are some symptoms to look out for.
- Are certain rooms much colder than others?
- Does it take a long time for system to warm up?
- Are one or more radiators cold at the bottom?
- Do radiators need frequent bleeding?
- Is the boiler noisy?
UK BUILDING REGULATIONS
In addition to the benefits mentioned above, the Compliance Guide to Part L of the UK Building Regulations for England and Wales requires a central heating system to be cleaned and flushed before a corrosion and scale inhibitor chemical is added during commissioning. It’s also prudent to do this when an old central heating boiler is being replaced by a new boiler. Many boiler manufacturers now make the warranty dependent on flushing and cleaning in accordance with BS7593, Benchmark and Part L.
