Power Flushing Bromyard

Do You Need A Central Heating Power Flush In Bromyard?

Should you need a power flush in Bromyard, look no further!

Could your central heating system do with power flushing? If some or all of your radiators are not heating up fully and have progressively got worse, or if you have have been told by a heating professional that you have sludge or limescale related issues, there is a good chance that you may need a power flush to resolve your issues.

Be aware, significant problems with heating systems can be caused by poor quality system water! Sludge, limescale and other sediments can cause cold spots in radiators, blocked heat exchangers, damage to components such as pumps, and many other problems.

Furthermore, power flushing is often done wrong, and as a result, consumers can end up paying far more trying to solve the problems associated with sludge, scale and sediment that they need to. The process could be done in many ways, but there are few correct ways.

You need to look no further! We provide a comprehensive and effective power flushing service at competitive fixed rates. We are regularly power flushing central heating systems and have a lot of experience with the process. When you use us, you are in the best hands!

We adhere to the Approved Codes of Practice such as those established for power flushing by the Domestic Water Treatment Association. We ensure that treated water is physically examined, checked with a TDS meter (total dissolved solids) to within 10% of the tap water supply and PH checked prior to inhibitors being added to the system.

“Sludge and scale are the leading cause of premature boiler and heating system failure. Any boiler that beats the lifetime statistics usually has clear system water within it that contains inhibitors, whereas boilers that are regularly having issues will almost always have dirty system water. There are a large number of heating systems that would benefit from a power flush, potentially saving the owners a lot of money in the long run.”

What Is The Process of Power flushing?

Power flushing is the process where a high velocity, low-pressure pump is used in wet central heating systems to loosen sediment and other unwanted substances (flux, solder, bacteria, etc). Following this, the power flushing machine extracts the undesirable matter from the system water by purging and/or filtration.

What Is The Right Method?

The correct and most efficient way, in most cases, is to adapt to or remove from the system the central heating pump and connect the power flush machine at this point. Alternatively, if dedicated power flushing connection points are installed, or where a filter is installed, power flushing can be done here in some instances. Power flushing central heating systems through radiators can result in poor results, although it is not always possible to avoid this.

In order to increase the speed of this process, magnetic filtration can be used to improve the process when sludge (ferrous oxide) causes a problem. This will often reduce the volume of water used.

The Use Of Chemicals

Using the right methods, equipment and appropriate chemicals at the right doses will increase the chances of successful power flushing. Strong acid-based chemicals, which require neutralisation with a separate product, will often be more effective than using a product that can be put into the drainage system as it is.

The common solids found in central heating systems are ferrous oxide, flux residues, limescale and other sediments. These can cause heating systems blockages and restrictions, reducing or even preventing water flow and heat transfer. The power flushing chemicals we use will break down most unwanted matter found in heating systems quickly and allow the power flushing unit to mobilise it in the system water. More serious problems, such as dense blockages, can reduce the effectiveness of the process, especially in micro-bore pipework.

Few engineers/companies that power flush in Bromyard use the best chemicals for the job, therefore reducing the effectiveness of the process!

Power Flushing Microbore Systems

Micro-bore systems can be effectively power flushed, but the lower smaller diameter pipes restrict the flow of water; thus power flushing is not always successful. Additional methods can be employed to increase the amount of sediment removed from heating systems successfully, such as individual radiator flushing and draining the radiator individually post-treatment, but it must be understood that there are limitations to power flushing. The more obstacles put in the way of the process, the less effective it will be.

Blockages From Building Sediments

The chemicals rarely will break down aggregates which may have contaminated the system during a home building or renovation process. The power flushing process will not likely remove such matter that has hardened. Aggregate contamination rarely occurs outside of new-build, extension and renovation projects.

Vented Heating Systems

During the process, header tanks (F&E tanks) feeding traditional central heating systems are disconnected and capped to prevent fluid passing into the tank through the vent or feed pipework.

F&E tanks can become heavily soiled with contaminants such as sludge, microbial growth and other sediments. If not cleaned out thoroughly once drained, the refilling process will reintroduce this unwanted material back into the heating system. Where possible, we advise the F&E is cleaned out and chemicals are used to kill any growth that may be present.

Can flushing power cause leaks?

Power flushing works at low pressure, so it cannot cause equipment to become damaged. However, the high volumes of flow could push apart any pipework or components that have not been jointed correctly, such as unsoldered joints or poorly tightened compression joints.

Small leaks can occur where sediments such as limescale or sludge have been sealing defective seals or corroded metals.

Does Power Flushing Work?

Power flushing is the most effective method to remove hardened sludge, scale and other sediments from within a central heating system. In most instances, it will remove almost all of these contaminants without the need for any other further work. It is what makes it a very cost-effective solution and the most widely used method by us to clean heating systems in Bromyard.

Common Problems Caused By Sludge/Scale/Sediment

Conventional systems:

  • Radiators heat up when the system is set for hot water only
  • Hot tap water getting scalding hot
  • Hot tap water failing to heat up
  • Reduced pump life
  • Reduced motorised valve life
  • Kettling from the boiler
  • Overheating of the system
  • Cold spots in radiators
  • System water “pumping over” into the F&E tank
  • Thermostatic radiator valves failing to work

Combination (Combi) boilers:

  • Radiators getting warm when systems demand is for hot water only
  • Hot tap water getting scalding hot
  • Hot tap water has fluctuating temperatures
  • Hot tap water failing to heat up
  • Reduced pump life
  • Kettling from the boiler
  • Overheating of the system
  • Cold spots in radiators
  • Thermostatic radiator valves failing to work

Analysis of System Water

We test the central heating system water quality through physical examination and the use of electronic equipment. Although it is possible to have a laboratory test water samples, we would rarely do this in the domestic sector due to costs.

Electronic test equipment such as TDS meters and thermal imaging can be useful, but experience and physical examination within the heating system and the water contained within are the primary tools used to determine when sediment like sludge and scale is causing a problem.


Inhibitors are chemicals are put into systems with the central heating system water which helps prevent corrosion, limescale and organic growth. What they protect from and how effective they depend on the products utilised and their concentrations. Products vary in quality and effectiveness.

Frequently Asked Questions

Yes, but not with acid-based chemicals! Aluminium reacts readily with acids and strong alkaline, thus less effective compounds must be used, or the boiler needs disconnecting from the heating system where acid-based chemicals need to be used.

It is very high, 99% of the time it will resolve the issue(s) without any further work. However, it will not be fully effective in certain situations.

We have seen situations where these chemicals are left in heating systems to pre-treat them one or two weeks in advance of power flushing and failed to remove blockages or clear the system of deposits which were removed in a short space of time once acid-based chemicals were added shortly after. We do not rate these chemicals.
