A powerflush is a cleansing process in which heating systems are forcibly cleansed through the use of a pump which uses water at high velocity but low pressure so that no physical damage is done to the system. The process aims to remove build ups of sludge, rust and other debris.

Most central heating problems relate directly or indirectly to sludge or lime scale in your system. Eliminating this makes problems easier to diagnose, helps prevent future problems and makes your system operate more efficiently and economically. It is recommended that an older system is power flushed to remove all debris from the old system before a new boiler is fitted.
• Most boiler insurance schemes want your system power flushed as standard.
• Manufacturers of your boiler, especially within its warranty
• Cold areas on radiators e.g. at the bottom
• Excessive noise from the boiler or the heating system pump
• Discoloured water when you bleed the radiators
• Heating is slow to warm up
• Cloudy tap water (limescale in system)
• Some radiators struggle to heat up as well as others
• Radiators cold but pipes are hot
• Boiler regularly shuts down and needs restarting
• No water escapes when you bleed a radiator
• Noisy radiators and or / boiler
• Small leaks in radiators.
If you carry out regular professional servicing and maintenance annually, then a preventative Powerflush should only be necessary every 5-6 years to clear debris and prevent significant blockages from taking hold
It depends greatly on how much sludge is in your system and system layout. Generally, half a day for a small system and a full day for a large one
We have used Merretts for 9 years to service our boiler. Engineers always arrive within the promised time, and are always professional. John is a very tidy worker with good communication. Very happy with the service.
We recently had to renew the semi commercial oil boiler in our house. Merrett’s Heating Services worked with us to replace it at the most opportune time, with the minimum disruption and mess. We are absolutely delighted with the result; the boiler is quieter, more efficient and has saved us about 30% of our average oil usage. Well recommended
