Why do I need a Power Flush?
In older systems, boiler noise and circulation problems are often caused by a build up of deposits in the heating system. This results in a reduction in efficiency and performance, with radiators having cold spots and being slow to warm up.
Boiler manufacturers insist that old central heating systems be flushed prior to installing a new boiler, and may even make this a warranty condition. Only by power flushing can you be certain that a system is really clean to the standards demanded by modern, high efficiency boilers.
How does it work?
The flushing pump is connected to the heating system and the powerful flow coupled with the flow reversal device dislodges and mobilises the sludge, limescale and corrosion in the system.
Once loosened, the deposits are pumped to drain, and each radiator is individually cleaned. At the end of the process, the system contains only fresh, clean water. Inhibiting chemicals are then added to ensure that the deposits don’t build up again. The system is then re-instated.
Will my radiators leak after power flushing?
The power flushing process is required due to the build up of
corrosion, sludge and limescale over a long period of time.
Occasionally, some systems have radiators with localised deep
corrosion pits, with only a scab of rust preventing water leakage.
Powerflushing may disturb this rust, causing radiator leakage, but
these leaks are waiting to happen and it is better that it should occur
with a trained heating engineer at hand to remedy the situation.
