Powerflushing a 4 bed terraced house in Balham, SW12

Firstly we’ll go into what a Powerflush is, and then talk about the job we did in Balham, SW12…

Power Flushing is a process by which heating systems are forcibly cleansed using water at high velocity, but low pressure, so that no physical damage is caused to the system.

The objective of A Powerflush is to restore systems with circulation and boiler noise problems (caused by sludge and corrosion deposits) to optimum operation. Power Flushing removes these deposits and the problems that they cause.
How Do I Know If I Need to Consider a Power Flush?

If your central heating system suffers from any of the symptoms detailed below, it would almost certainly benefit from Powerflushing:

Fitting a new boiler
Central heating system slow to warm up
Some radiators partially or completely cold
Radiators require frequent bleeding
Water in radiators is discoloured and dirty
Central heating system has repeated pump failures
Warm water in the header tank

What Are The Benefits of a Power Flush?

Increased efficiency to central heating and hot water
Lower fuel bills (up to 25%) because things are working a lot more efficiently
Radiators heat output restored
The whole central heating system is cleaned
Sludge removal and de-scaling in one visit
Now a requirement for most boiler warranties – have you checked yours?
Peace of mind

Why Do I Need to Power Flush My New Boiler?

The most important reasons are:

Ensure the efficiency of your new boiler by up to 25%, and prolong the life of the various parts inside it
Your boiler warranty may be invalid. Check your warranty.
UK Building Regulations require existing central heating system to be thoroughly cleaned before connecting up the new boiler.

How Does Powerflushing Work?

We have to connect our powerflush machine to the heating system, across the circulator pump valves, or the tails of one radiator, or wherever most practical. The powerful flow, combined with instantaneous flow reverser device, will dislodge and shift built up deposits and corrosion, which resist traditional system cleaning methods.

Once the corrosion and sludge deposits have been loosened and mobilised, fresh clean water is forced through the heating system, pushing the contaminated water out. During the process, radiators are individually flushed, without removing or disconnecting them from the system, and we work our way around the system until all the radiators are clean.

Once done, we refill the system with clean water and add some corrosion inhibitor to help prevent any future corrosion or sludge build up.
How Long Will It Take?

Normally for a standard size property the process can be completed in a day.
