Could your boiler benefit from a power flush?
A power flush is an accepted maintenance procedure which removes sludge from your heating system. This mucky build up can cause blockages and make it harder for the water to circulate through your pipes and radiators. This in turn means your boiler has to stay on longer, work harder and cost you more money. Even if your boiler is fairly new, sludge can really affect its efficiency.
So does your boiler cut out or make banging noises? Or does your hot water taps fluctuate between hot and cold? Have you notice other issues such as cold radiators, excessively hot pipes or dirty water when you bleed a radiator? If so, it’s very probable your heating system would benefit from a power flush.
The objective of flushing a heating system is to improve circulation and reduce boiler noise problems (caused by sludge and corrosion deposits) and thus optimise operation. Flushing removes deposits and the problems that they cause.
When our engineers come and flush your heating system they will use a special high powered pump and appropriate chemicals. (It is not sufficient to attempt to rinse out individual radiators or parts of the system using just a hose pipe and water).
Existing debris is often mobilised by alterations to the system, the increased efficiency design of the new boiler makes it much easier to be impacted by this debris, because it is much easier to accumulate within the boiler heat exchanger, causing noisy operation, reduced efficiency and, in extreme circumstances, failure of the boiler.
It is essential to 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.
Some boiler manufacturers insist that systems are flushed properly when a new boiler is installed. If a warranty claim is made and it relates to a water component, they may sample the system water and if found to be dirty because of lack of power flushing, the warranty may be deemed void – resulting in an expensive repair.
We can advise on flushing existing boilers and systems, and would be glad to provide a quote. We always flush a system prior to commissioning a new boiler.
So if you have had British Gas or another company out and told you that your system needs power flushing? Well, you are not alone! We get a large number of customers ring us and ask about power flushing, usually, asking how much we charge to power flush a central heating system.
Many of the people who ask about it have been told that it is needed. However there are occasions when power flushing would not cure the problem(s) these people are experiencing with their heating system. So why would they have been advised to have their systems flushed? Well, the following reasons may apply:
- Generates income
- Keeps employees busy / helps build workload
- Uncertain diagnosis (maybe the flush will work!)
As power flushing can be a time consuming, labour intensive process, it is quite expensive. It would be very annoying for a customer to pay out several hundred pounds to have their systems flushed, only to find that the resulting performance is little or no better than it was before the flush.
For anyone who is advised by British Gas, (or anyone else), that they need to have their heating systems flushed, we suggest that the work is carried out on a “no-win, no-fee” basis. We doubt that British Bas would agree to this, nor would we!
For this reason, we sometimes advise that a power flush may not be the answer to a problem. There are other options, depending upon the problem and the system layout. We are happy to visit a customer’s home to look at their heating system and determine the need for a power flush. The last thing we want to do is power flush a system, charge hundreds of pounds, only to find that the system is no better afterwards.
In addition to power flushes, our fully qualified engineers can carry out a variety of boiler maintenance processes, such as magna cleaning, scale reducer applications, CO2 and flue gas tests and inhibitor and central heating protection.
