Power Flushing of your Central Heating System

The Symptoms:

Your boiler or the pump is noisy or failing
Combi boiler hot water cycles hot and then cold - boiler fires up then goes off
Hot water temperature is only lukewarm at best
Boiler overheats or shuts off when in hot water or central heating mode
The radiators and other parts of the system are leaking
It takes ages for the system to heat up
Regular need to bleed air from the radiators
Evidence of sludge and rust in the system
The radiators have cold spots or are not working

What is a Powerflush?

A powerflush is a cleaning process which aims to remove any rust, sludge, limescale and corrosive deposits from your heating system.

We highly recommend a power flush for your heating system to make it more efficient, which can save you money in the long run on energy bills. We also recommend that you have a powerflush if you are having a new boiler fitted, as its warranty may not be valid if no power flush of the existing radiators and pipes was conducted prior to its installation.

One of our engineers will connect a powerflush machine to your heating system at either the tails of a radiator, the boiler or a standard circulator pump coupling, where ever is the most convenient point for you. The powerflush machine will flush water and cleansing chemicals at a high velocity through the whole system, but at a low pressure rate so as not to damage your system.

A power flush will normally take between 4- 8 hours, depending on the size and condition of the system.

All of our GasFirst engineers are fully qualified and receive extensive on-going training to ensure all of their knowledge is up-to-date, therefore providing you with the best possible service.
At the end of the Powerflush, you`ll be issued with a Central Heating Cleansing Certificate and the system will also be treated with an anti corrosion inhibitor to prevent further deterioration.

We strongly recommend the fitting of a dual magnetic / debris filter immediately following a Powerflush as this will further protect the central heating boiler, prolonging the lifespan and ensuring efficiency.

The powerflush cost will depend on the size of your central heating system, but as a guide:

1 to 5 Radiators - From £225
6 to 10 Radiators - From £325
11 to 15 Radiators - From £425

Adding a magnetic filter during the Powerflush process will add between £100 to £150 to the cost.
