Why choose power flushing?

safeReduce the risk of boiler failure:

Assuming that no other faults exist, accumulated deposits of sludge and scale can restrict the transfer of heat to the extent that the boiler can overheat and fracture on an unmaintained system. Power flushing reduces the likelihood of this occurring.

Reduces Fuel Bills:

In untreated systems, corrosion particles can accumulate in pipework. 3mm of limescale inside your domestic boiler can add 18% to your fuel bill. Current British Standard require that prior to a new boiler installation, the system must be cleaned. Power flushing is the best way to do this.

Pump Seizure:

Black oxide sludge is magnetic and abrasive. It puts excess pressure and wear on pump bearings which is one of the most common causes of pump failure.

Quick and Simple Service

We simply connect our equipment to your pump or radiators, add some chemicals to de-sludge your system and then cleanse it. Most Power-flushers can be done in just one visit. It is a clean and efficient service.

It is prudent to power flush a heating system immediately before fitting a new boiler to an existing system to prevent possible future problems. Many systems are found to contain corrosion and sludge, even if no flow problems have yet shown themselves.

All of our plumbers are fully qualified and carry out work in accordance and complying to current regulations. We also have full coverage with our Public Liability Insurance.
