Correct Power-flushing will clear debris from heating systems. This debris is usually caused by either incorrect piping causing air to be sucked into the system ( on conventional gravity type systems ) or due to a lack of maintenance allowing corrosion of the metals in the heating system. This debris can cause damage to the boiler and additional components such as pumps and valves. Once the system is flushed I would advise fitting a magnetic filter and inhibitor to the system. Once a system has been properly flushed you should notice an improvement to the heating of your system. However most Boiler manufacturers do not ask for a system to be power flushed before fitting a new boiler. They request that a hot chemical flush is carried out in line with the fitting of a magnetic filter as mentioned above. Check with your installer his recommendation as to which of the above would be beneficial to your system etc. Please bear in mind that old pipework, pipes in concrete and small bore may not be able to accommodate the pressure from a power flush and a chemical flush would be a wise and safer route to take.

Power flushing is particularly important if,you have a conventional boiler, that has a feed & expansion tank. This is a small tank usually in the loft space. This is because the water has open contact with air, (unlike a pressurised system, Combi or system boilers) This means the inside of radiators, will rust more & protective chemicals, will evaporate or dilute. If a modern boiler is fitted to an older system, the water ways on the new boiler are much smaller. So any rust particles can damage, or effect the new boiler.

Power flushing in extremely beneficial to a heating system and it’s heat source. Whether it’s on an existing system or a new system. It is one of the best ways to clean the pipework and radiators. Power flushing is best completed prior to a new boiler being installed. As most new boilers have a low water content, and have smaller water ways, pumping old oxide round a new boiler can be extremely harmful to the new appliance. Flushing a system is also very important for longevity of the system. It increases the efficiency of the system as well as making the radiators work better, giving out more heat.

You'll read lots of varying information about power flushes, such as it being a requirement to valid boiler warranties, or to extend the life of your boiler. From our 20 plus years of experience, vee don't agree that a power flush is absolutely necessary. It's a lot of money to spend when there are cheaper alternatives out there. When installing a new boiler into an old system, it's common practice to mains flush the system, this flushes out the old water and when refilling, cleaner chemicals are placed inside which effectively cleans the system. This is then drained after 7 to 10 days and your system is refilled with inhibitor. Make sure you also have a magnetic filter on the system. This option is a fraction of the cost of a power flush. With that said, if your system is suffering quite severely with failing cold radiators ect then it's normally a power flush that gets recommended by most companies. Not us, in fact, it could well be cheaper to just replace your radiators with new ones, add the inhibitor and not have to worry any longer!

powerflushing is an important part of the boiler installation process which cleans existing pipework at an high velocity in conjunction with the right chemicals before the new boiler is installed, if done correctly the new boiler & new or existing radiators can achieve the right heat output as circulation through the system is normal also if the system is maintained well by checking inhibitor levels on a service visit there is less chance of the boiler breaking down, this is very important especially on old back boiler conversions.

The main benefit of having your system PowerFlushed is having all the debris, sludge and rust particles removed from your radiators, boiler and pipework. This enables your system to run at a much higher efficiency, thus reducing your gas consumption and running costs. Powerflushing increases the longevity of your complete heating system and validates the warranty on your new boiler, as all manufacturers now require a Powerflush of an existing system if you are having a new boiler fitted. We highly recommend a magnetic system filter to be fitted after a powerflush - this traps and keeps all the sludge ( magnetite ) that builds up over time, and can be removed when you have your boiler serviced. This keeps your system in ‘Tip Top’ condition - reducing faults and breakdowns over the boilers lifespan.

By having a powerflush on your heating system you are prolonging the life of your boiler and the whole system thus enabling it to work more efficiently and effectively. This will reduce your gas bills and heat your house a lot quicker. I would always advise to have a system filter installed after the powerflush.

A power flush can help maximise the efficiency of your boiler and central heating system. After a power flush, your heating system could be restored to nearly-new condition, without the hassle or financial expense of replacing an old, inefficient boiler. A power flush involves circulating high-strength cleansing chemicals, including a descaler, a corrosion inhibitor and a sludge breaker, throughout a central heating system in order to remove debris, rust and contaminants. The aim of a power flush is to improve system circulation and, therefore, efficiency that ultimately saves you money. After your central heating system has been flushed, you'll know the benefits straight away. Internally your heating system will be operating much more efficiently. The cleaner flow of hot water may even reduce boiler and pipe noises! Any of the following could be a sign that your central heating system needs a power flush: - Inefficiency and lost heat - Little or no hot water - Cold spots on radiators - Dirty water when bleeding radiators - Pump or valve seizure and/or failure

Pavlou Plumbers answered the question "What are the benefits of powerflushing?"

The main benefit is financial which affects the environment. If you have an old heating system with water tanks in the loft or above a hot water cylinder, you are more likely to require a central heating flush than if you had a pressurised heating system. This is because the black sludge is a form of rust which can only occur when there is oxygen in the water. As you may know there is oxygen in fresh water. The water that has been in your heating system has a lot less or no oxygen because the oxygen would separate from the water when it heats up. If you do have a pressurised system with a pressure gauge and you find yourself increasing the pressure regularly by topping up the water, in effect the end result is making black sludge. If the pressure is going down regularly contact your heating engineer. Going back to the question of the benefit of having a flush is, heating black sludge costs money and it won't heat up like water. The less sludge in your system the quicker the water in the system will heat up. Also having no sludge in the system means boilers, pumps, motorised valves all last longer.

When it comes to power flushing it's hard for a customer to see the benefit in doing so. It costly and your not actually going to see anything for your money. But wait!!! Have you been having issues with your boiler or heating system lately,components breaking, seals leaking, pumps seazing. Have you a cold radiator on the system that never heats up? Have you noticed a room or two colder than the rest of the rooms? Have you got a half moon shape at the bottom of the radiator? Have you got a rasping noise coming from your boiler? Have you noticed black water coming from your radiator when you need to bleed them? Are you bleeding your radiators excessively? These are all signs that may need a power flush on your system. You may not see what you get for your money with power flush but over time you will save hundreds of pounds on break down and on your heating bills which will pay for the power flush itself. You see overtime inside your heating system the water can react with the steel in the radiators and this creates a black /grey substance called magnetite. (Magnetite) is a by-product of of iron and is released as oxygen and water react with the steel inside your radiator. Only recently have plumbing and heating professionals been adding a chemical to the heating system to stop this reaction called (Inhibitor). It has become vital to add this to system due to the fact the newer more efficient boilers have much smaller water ways inside there heat exchangers and magnetite can have a detrimental effect on these newer boilers. Power flushing old heating systems with the above issues is a great way to rid your system of the dreaded magnetite. Which can cause a huge amount of issues time and money to resolve. Make sure that, if you are having a new boiler installed that you're plumber or heating engineer power flushes the system, uses the correct chemical cleanser,to clean the system and then he doses the system,with a good inhibitor to stop this happening again. Believe me power flushing can turn an old inefficient heating system with radiators that are not heating and a noisy boiler into a brand or system that is continually breaking down into new efficient heating system saving you money on your gas and plumbing bills hand over fist!

Loud running system, poor flow or over heating boiler. Poor heat from radiators and slow to even get warm. These are just some of the faults dirty heating systems can suffer from. With a full power-flush connected directly into the current heating pump, either internal of the boiler or external is the best possible place to start a flush. Heart of the system maximum flow while cleaning with a large pump which separates the dirty from clean within a system. Chemical is used and adding heat can speed the process Along. Combi boiler suffer badly from dirty systems as their plate heat exchangers are very small like a Honeycomb. This causes the hot water to run hot and cold every 30seconds. All radiators are cleaned, coil within a cylinder and of course the boiler.

A powerflush is way of cleaning your heating system an washing it free from magnetite (black sludge). It works by attaching a machine to the system that has a pump attached, this then pushes water around your system at high velocity along with a chemical. You can change the flow backwards and forwards to help the process, large magnets can also be added to the unit to attract and retain the magnetite deposits. The process will usually take about a day and should involve each radiator being isolated individually throughout the cleaning process to ensure each one is cleaned thoroughly. The main benefit and the one which is the most important of all is that it will prolong the life of your boiler and all associated items within the heating circuit. Another benefit is that it will give you even heat throughout all of your radiators, plus quiten down the whole system if it was previously very noisy. Whilst Powerflushing is a great way to clean a system it does come with risk. If you have a system that is very old or poorly installed it can loosen or pop off fittings causing leaks, while this isn't a regular occurrence you will normally be asked to sign a waiver for this reason. However there are othet ways of cleaning a heating system that are very effective if done properly.

Having a powerflush done will both greatly improve the efficiency and the life span of your heating system, saving you money on your heating bills and costly repairs. A powerflush will remove the sludge which has built up in your heating system. If a system is left untreated, the sludge will cause a range of problems such as: - cold radiators/ cold spots on them - Heating is slow to heat up - excessive system noise - cause your pump to keep burning out and need changing - cause 2 and 3 port zone valves to seize open or shut and burn the motor out - cause leaks/ pin holes on your radiators - cause automatic air vents to leak - blockage on main heat exchanger and pipework. - block the plate heat exchanger on a combi so the hot water doesn’t get as hot or runs hot and cold. A boiler and heating system install is one of the biggest purchases in a property. A powerflush should be seen as an investment in your heating system to protect it and keep it running smoothly and efficiently as is was designed to do. You wouldn’t buy a brand new car and then never change the oil inside it, same thought process should be taken with looking after your heating system to ensure the water inside it is as clean and protected as possible.

Powerflushing a central heating system provides several benefits. It removes sediment, sludge and contaminants from within the system providing greater system efficiency - radiators emit heat better when they are not full of muck! Reducing gas bill, co2 emissions and wear and tear on your boiler. It’s also prolongs boiler life and reduces breakdown as sludge and harsh system water, block and attack parts within the boiler. It also helps honour manufacturer’s boiler warranties as most are voided by boilers fitted to dirty systems. Powerflushing is highly recommended when installing a new boiler onto an existing system. Along with the installation of a good quality (ideally brass) central heating filter to prevent any further contaminants from affecting your new boiler.

First question would be, Why would you need a Powerflush? when a system is starting to get older, particles from the metal in the system starts to breakdown by the oxidized water. Then that can get trapped in the heat exchanger of the boilers, the radiators, even the pipework. creating cold spots or knackering the boiler itself. So a powerflush is a key bit of kit to keep your heating system maintained. The main benefit of a powerflush. is to clear your heating system of as much sediment as possible.

Every system requires some degree of a flush when installing a new boiler, whether it be a mains cold water flush with a magnetic filter or a power flush. If the system is reasonably new and the system water is generally clear then a mains flush should be sufficient. If however your system water is black, orange or a greenish colour you would definitely benefit from a power flush. A power flush is a lot more thorough than a mains flush because of the high velocity pump and powerful magnets which helps remove the built up sludge/magnate which sits at the bottom of the radiators creating cold spots. If left untreated this sludge/magnate will be left to circulate around your heating system and find its way into the boilers moving parts creating leaks and possibly even invalidating your boilers warranty. Regardless of which boiler brand you choose they all need a clean system and a regular service.

Power flushing is the only sure was to clean up your heating circuits and radiators. The qualified power flusher you use will give the entire system a chemical treatment which breaks down sludge and magnetite and then turn by turn flush each radiator out. If the engineer has a posh machine with a flow direction diverter (like me :) ) he/she will be able to dislodge stubborn build ups of magnetite and rust particles that have settled in a nicely compacted mound in the middle of your radiators. By removing this build-up you should get a nice and even temperature distribution from top to bottom of your radiators. This also means that your boiler should be working more efficiently and there's less chance of the nasty bits floating around your system clogging up your boilers heat exchanger. Remember that if you have an older boiler that's working fine with no problems it doesn't mean you don't need a system flush, old boilers have huge heat exchangers that have large heat transfer channels that are unlikely to be affected by magnetite and sludge, however when you upgrade your boiler to a nice new modern one remember the heat exchangers have tiny passage ways which WILL clog up and may damage your shiny new boiler. Talk to a power flush engineer and get them to do a water sample for you, you will know straight away if the water quality is detrimental to your heating system. Also note a full thorough flush will easily take 4 to 5 hours on a standard 3 bed house.

Powerflushing can be found to be necessary after a number of years when a heating system has been poorly installed or poorly maintained and either blockages have occurred in pipework or a build up of sludge has reduced the flow of heating water around the system. Powerflushing can remove most of this sludge or debris bringing back the initial efficiency and performance of the heating system. There is no British Standard for powerflushing however so the effectiveness of any particular powerflush can be questionable. It is strongly advised that heating system water should be kept in good condition by the use of system cleansing agents and anti corrosion 'inhibitor' solutions together with system filters which stop harmful magnetite etc blocking the waterways of your boiler which would decrease its efficiency.

When a heating system is installed it comprises of different metals in the presence of water which is the perfect conditions for galvanic corrosion. The addition of a corrosion inhibitor will only slow the process and so a magnetic filter should also be added to the system to collect magnetite, the by-product of corrosion, and prevent it entering the boiler heat exchanger which can cause costly system failures. Over the course of about 5 years the dilution of inhibitor and accelerated corrosion in the presence of magnetite requires a full drain down of the system, flush and refill with new inhibitor. At this time it is opportune to perform a hot power flush with a specialist cleanser and radiator agitator to ensure the removal of all the sludge and magnetite which commonly accumulated in the lower centre of the radiators which reduces flow and heat exchange capacity making the system less efficient. The process takes about 1/2 a day for a 7-10 radiator system and costs in the region of £400-£600 but will see savings over the course of 5 years on fuel usage and component failure as well as keeping the system nice and quiet. No more gurgling boilers at 3am.

Eventually, the sludge in your system could also cause severe blockages and damage, leading to a costly breakdown to repair. During a power flush, water is sent rapidly through the system to extract debris, limescale and sludge.

There are many benefits to having your heating system power-flushed! Firstly it gets rid of all the built up sludge, deposits and grime in your radiators and heating system (whilst having it done you will see the nice brown/black water coming out from it all!) It extends the life of your heating system and therefore saves you money in the long run. Your radiators will warm up quicker as there will no longer be any cold spots in them due to the build up of gunk! It will reduce your energy bills too as the system will now be more efficient due to the cleaner water travelling through the pipework, boiler and radiators. Look after your heating system and it will look after you!
