Infinite Heating Services provides power flushing across Cheshunt and the EN8 area. Over time, central heating systems build up deposits of sludge, rust and scale that reduce efficiency and cause cold spots on radiators. Power flushing clears these blockages using specialist equipment, restoring heat flow throughout the system. It can extend the life of your boiler and bring down your heating bills. Call 07480780630 to find out if a power flush is right for your system.
More Information
There are several signs that a central heating system would benefit from a power flush. Radiators that are cold at the bottom but warm at the top suggest sludge has settled in the lower sections. A boiler that makes banging or kettling noises is often dealing with limescale or magnetite in the heat exchanger. Slow heating response times, discoloured water when you bleed radiators, or a system that has not been flushed for many years are all indicators that a power flush would help.
We connect our power flushing machine to the central heating system and pump a high-velocity, low-pressure flow of water and cleaning chemical through every pipe and radiator. This breaks up and flushes out the deposits that have accumulated over years. We add an inhibitor at the end to protect the system going forward and prevent future build-up. The whole process usually takes between four and six hours for a typical home in Cheshunt.
If you are installing a new boiler, most manufacturers strongly recommend a power flush of the existing system beforehand. Fitting a new boiler onto a dirty system means that sludge and debris will circulate through the new heat exchanger from day one, which can cause damage and void your warranty. We always advise a power flush when fitting a new boiler into an older system.
We recently carried out a power flush on a 1990s detached house in Nazeing where four of the eight radiators were barely getting warm. The system had never been flushed in its thirty-year life and was heavily congested with black magnetite sludge. After the flush, all radiators reached full temperature, the boiler ran more quietly, and the family reported noticeably faster heating response times throughout the house. The difference a clean system makes is remarkable.

STILL NOT SURE?
Common signs include radiators that are cold at the bottom, a noisy boiler, slow heating, or discoloured water when you bleed a radiator. If your system is more than 10 years old and has never been flushed, a power flush is worth considering. Call Infinite Heating Services on 07480780630 for advice.
A power flush for a typical Cheshunt home with six to ten radiators usually takes between four and six hours. Larger systems with more radiators or more severe build-up may take longer. We will give you a realistic estimate when we assess your system.
Most boiler manufacturers recommend or require a system flush before fitting a new boiler, particularly into an older system. Fitting a new boiler into a dirty system can cause premature heat exchanger damage and may affect your warranty. Infinite Heating Services can carry out a power flush as part of a new boiler installation in Cheshunt.
