powerflushing

Why powerflush?

If sludge and debris is not removed from heating systems, it can accumulate in radiators, pipework and heat exchangers, causing severe blockages.  This diminishes the transfer of heat and can result in pipe, radiator valve and heating control servo valve damage. In some cases this will eventually lead to the premature failure of the boiler.

Powerflushing is a popular method of cleaning and maintaining a central heating system. A powerflushing unit sends water at high velocity through the system to dislodge and remove debris, limescale, and sludge build-up. A thorough powerflush will improve heat distribution throughout the property, subsequently lowering household energy bills and increasing system reliability.

A Powerflush machine has it’s own built-in pump so when this is connected to your heating system, in place of the existing central heating pump, a cleaning solution is pumped throughout the entire system. Each radiator can be isolated ensuring that all internal pipe work is cleaned, eliminating the risk of sludge, iron oxide or magnetite damaging your new boiler and controls.

An initial check of the house needs to be completed, in addition to consulting with the homeowner. Potential highly sludged areas should be identified, i.e. cold radiators, as well as areas which are highly corroded. When highly corroded components are observed, the homeowner should be aware that cleaning may expose leaks in the most corroded areas.

Why not have Carbon Catch give you a quote for this process. It will make a noticeable difference in any home with old radiators that are struggling to heat properly through sludge and rust build up.

Types of blockages

Sludge: Water and air will combine to create rust in your pipework and radiators which will then turn to sludge. It can be found in most heating systems over five years old. If left it will harden and block radiators and pipework over time.

Limescale Pellets with Oxidised Copper, Rust and Aluminium: If you find this in your header tank you have a serious problem which will manifest itself in boiler noise and a serious loss of efficiency. This will occur where the hot system water is pumping over into the supply tank and constantly refreshing itself, thereby manufacturing a constant supply of limescale

Flakes of rust: This is the most recent type of blockage. Most common in radiators fitted in the last twenty years and even more common when installed alongside plastic piping. If your pipework is 10mm it can block solid when allowed to rest over the summer months if you have not run your heating system.

How do I know I need a powerflush?

Cold areas on radiators, even after bleeding

Takes a long period of time for radiators to heat up

Noisy boiler

Radiators requiring regular bleeding

Inefficient central heating unit

Obstructed central heating system

We can arrange for a survey and will take thermal images of your heating system showing where it is losing heat. Once the job is complete we will provide you with a certificate and a five year guarantee against any future blockages.

Powerflush results!

Radiators and pipes will get hotter quicker.

More effective system.

Less tension on the boiler.

Increased life of the boiler.

Heat will be dispersed more equally throughout the home.

Central heating boilers can fail early if there is excessive sludge in the system, modern-day condensing boilers are much more sensitive so it’s suggested to have a full system flush before setting up a new boiler. There is no point in spending money on an expensive appliance that may fail early because of excessive sludge build up in the system!

If the system hasn’t been recently power flushed, you need to also check the guarantee on any brand-new boiler/s as a lot of makers will not accept an insurance claim.

If a new boiler is being set up and/or if the system hasn’t been cleaned for a long time, we would advise property owners to have this work done. When working efficiently, the system will run more economically, saving you cash.

How Does A Power Flush Work?

During the preliminary assessment, your chosen specialist should have explained the work involved and the expected cost savings.

Prior to beginning with the work your trades-person needs to check the boiler for correct operation and all the radiators for cold spots, ideally taking the temperature of each radiator. A sample of the water ought to also be taken– for comparison.

When all radiator valves have actually been removed or opened, dust sheets placed over carpets etc, the power flushing machine can be connected.

The first flush involves a chemical power flush of the entire system consisting of a reverse circulation, this normally takes around 20 to 60 minutes. Each specific radiator is then flushed individually, starting with the coldest rads. A rubber mallet can be used to relax any scale/sludge. This procedure is then duplicated across all the radiators.

A 2nd flush happens throughout all radiators separately.  The second part of the process involves adding cleaning chemicals which have been specifically made to suit your boiler. The fluid is then reversed periodically until all cold spots have been removed from the system.  A rubber mallet is also used to gently knock the bottoms of the radiators to free any bits of rust that are reluctant to leave the system.

A final flush of the system is then carried out using fresh water whilst checking the PH & TDS readings of the water being discharged. (All chemicals are neutralised before being removed safely).

An inhibitor is added to the water and distributed through the system for 15 minutes. A sample is then taken and tested, more inhibitor can be included if needed. The TRVs (thermostatic radiator valves) are then refitted and set to the optimum setting as the system is ‘balanced’).
