Did you know you can save up to 70% on your heating bill?


Old conventional boilers had very few parts and cast iron bodies, this meant they could take a 'hammering' for many years and you would probably only replace a couple of pumps. Nowadays the new combi and combi-condensing boilers we have in our homes have many sensitive parts which can be very expensive to replace.

When the experts investigated why these parts were failing (sludge, debris, iron filings being the cause) the first 'powerflush' machine was born in 1996.

Since then the machines and chemicals have got even better and you now get great results with the extras on the machines like 'magnetic filters'.

If you have had a new boiler fitted or especially if you have had one swapped then you need a powerflush! Don't wait for your parts to start to fail and a heating engineer to tell you, you need one.

The most common and often most expensive part to go due to this build up on a combi system is your heat exchanger. But lots more parts are effected also.

Sadly people are not aware of these facts and usually get informed by the big companies who they pay a monthly subscription to, to cover their boiler parts that they need one.#

This is not included in their price and every winter they charge their customers a fortune for this service as soon as any part fails for what is half a days work.

In doing this they not only make a large profit from you the customer but they insure that the likelihood of them replacing anymore parts is minimal once the flush has been done (pocketing your monthly subscription as well).

Water in central heating system is contaminated with rust, sludge and other debris because of internal corrosion. These corrosion products are causing circulation and boiler noise problems, premature failures of heating system components and reducing system efficiency (increasing your fuel bills). System needs to be flushed and cleaned and the best solution is powerflush.

Power flush is the fastest and most effective way to flush heating system.

How does it work?

Power flushing pump is simply connected into the heating system, either across standard circulator pump couplings, across the tails of one radiator, or wherever most practicable.

The powerful flow, combined with instantaneous flow reverser device, will dislodge and mobilise 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 through a full bore dump valve to waste. During the process, radiators are individually flushed, without removing or disconnecting them from the system, by directing the full output of the pump through each radiator separately.

At the end of the flushing process, the system contains fresh clean water, scale and corrosion inhibitor is added giving long term protection to heating system. Reinstatement of the system to normal operation takes only a few minutes.

Boiler Descale

When hard water is heated, calcium and magnesium contained in the water can build up a limescale in the central heating system, especially in boiler's heat exchanger. This creates an insulating layer, reducing heat transfer to the water and reducing efficiency of the boiler.

A 1 mm layer of limescale will cause a 7% increase in energy input to the boiler to meet the same heat demand, so more gas is burned and fuel bills are much higher.

Limescale can also restrict or block water passageway in the central heating system (especially in boiler heat exchanger) affecting water flow rate and reducing water temperature.

WE can solve the problem by using powerflush pump and descaling chemicals which dissolve limscale leaving your system completely clean.#

Power Flushing

One of the most effective ways to clean a central heating system and one of the easiest ways to fix a wide range of problems.

It’s a technique that can be used to clear out sludge, dirty water, rust and even debris from within household pipes, radiators and heat exchangers which can all affect the integrity and efficiency of your central heating.

We have a network of trusted, reliable and experienced Gas Safe registered engineers who can conduct a thorough power flush on your system; cleaning it out, de-sludging and bringing a new lease of life back into your heating.

So, how do you know if you’ll need a power flush? Cold spots on radiators, poor hot water flow, noisy boilers, boiler circulation problems or if you’ve never had a power flush on your central heating.

Power flushing can also help to lower your household bills, prolong the life of your boiler and system, provide a more even distribution of heat around your property, increase the reliability of your system and save on your overall energy.

The Consequences of Having a Blocked Central Heating System

Central heating performs best and at an optimum level when the water is able to move through the system unhindered. Where there is sludge or debris, the boiler has to work twice as hard as it inadvertently has to heat up this debris as well as the water.

Some of the heat is absorbed into the sludge and therefore the boiler works harder to get to its desired temperature or does not reach the desired temperature at all. This can get worse over time as the boiler begins to get more and more stressed.

The Benefits of Having a Clear Central Heating System

If you carry out regular boiler services and maintain the boiler and central heating system, a power flush should be conducted around every six years as a preventative measure.

A clear central heating system will ensure that the water travels around more freely and will heat up quicker due to the lack of obstructions. This will mean a longer life expectancy of the boiler and its key components which will also mean a decreased likelihood that you’ll have to pay for costly repairs. Noise will also be significantly diminished as there will be no vibrations which are caused by blocked flow paths.

More to Consider

Installing a dirt and air separator to a home's heating system can potentially cut £80 - £160 off the average heating bill, according to new research commissioned.

Trials were conducted in independent laboratory testing facilities and installed on the heating systems of 200 homes over a four-year period, using a dirt separator and DE aerator.

The study found that the dirt separator and deaerator improved heating system efficiency and reliability by capturing and removing dirt and air, which can cause blockages, reduce pump performance and corrode system components.

"Reduced energy use equates to lower fuel bills and carbon emissions, while fewer system blockages and component failures reduces the risk of breakdowns"

The unique magnetic field booster technology guarantees fast and optimal dirt separation. Next to non-magnetic dirt even the smallest magnetite particles are removed, maximising system performance as well as protecting costly system components. Thanks to the ingenious design, collected dirt can be removed quickly and easily. The sturdy brass Spirotrap MBL are suitable for horizontal, vertical and even diagonal pipes.

The Vortex Energy Saver product was invented to help people save on heating costs. Dye to the unique design of this deaerator, the Vortex Energy Saver is the only product on the market proven to reduce Oxygen levels in the water of the heating system down below an inert level (less than 0.5ppm). By doing so the properties of the water are improved causing the water to heat up quicker using less energy. With no Oxygen in the water the Vortex Energy Saver helps prevent corrosion and extends the life of the heating system.

Removing the dissolved Oxygen to an inert level has proven to save on heating costs as much s 35%!

Combine these services with the new Valves (TVR's) and you will have a system more efficient than when it was first installed.

Looks expensive right?

We can do all or part service, but with a part service we cannot guarantee the results.
New central heating system.
The cost can be anything from £2500 to £5000.
You have the disruption, plus nothing is going back inexactly the same place. So, now either you get the decorator in or you spend more money and time on DIY. Once you have re-decorated, then there's the colour scheme, so new curtains are required etc etc.
It's far less expensive and disruptive to have a full heating refurb.
