What is a Power-flush?

A power flush is a process of cleaning central heating systems using a machine which pumps high volume, low pressure water and specialist chemicals around the pipes.

Central heating systems, if not cleaned regularly, can become clogged up with sludge, rust and other debris. This can seriously affect the efficiency of the heating system and possibly lead to blockages, making the heating system sluggish and, over time, leading to breakdowns.

When do you need a Power-flush?

If you carry out regular servicing and maintenance (professional servicing is recommended annually) then a preventative Powerflush should only be necessary every 5-6 years to clear debris and prevent significant blockages from taking hold.

However, this will vary depending on the system you have. For example, some boilers use copper heat exchangers rather than stainless steel, which will corrode quicker.

Signs you need a Power-flush

There are signs to look out for that suggest that all is not well in your central heating system.

• Cold areas on radiators e.g. at the bottom
• Excessive noise from the boiler or the heating system pump
• Discoloured water when you bleed the radiators
• Heating is slow to warm up
• Cloudy tap water (limescale in system)
• Some radiators struggle to heat up as well as others
• Radiators are cold but pipes are hot
• Boiler regularly shuts down and needs restarting
• No water escapes when you bleed a radiator
• Noisy radiators and or / boiler
• Small leaks in radiators.

If any of these problems sound familiar to you, it's time to contact The Gas Man Services. While a Powerflush may be all that is required to get your heating back on track, unfortunately it is not always that simple. A system may be so damaged that it is actually cheaper to replace rather than repair. If that's the case we will advise you of the best solution and give you a free quotation.

What are the benefits of a Power-flush?

It's not all doom and gloom; there are lots of positive reasons to get a Powerflush carried out too.

• Radiators will heat up quicker
• Radiators will get hotter
• Quieter radiators / boiler
• More energy efficient system = cheaper energy bills
• Higher hot water temperatures
• More reliable i.e. less chance of breakdown
• Increase the life of your heating system.

How does a Powerflush work?

We will connect what we believe is the best power flushing machine the magmaster proflush to your central heating system. If it's a Combi it will be connected at the pump head but if it's a system boiler it will be connected at the circulation pump. This pump will push special chemicals through the pipes, boiler and radiators.

This includes a chemical that will remove sludge and rust, a descaler to remove limescale and corrosion inhibitor to help prevent future rust from forming. We will collect and dispose of any contaminated water, debris or particles that they remove from the system.

We also use special tools on the exterior of the radiator to dislodge stubborn blockages.

We will measure the temperature of your radiators before we start work, using the latest in thermal imaging and then show you the improvement after the Powerflush.

The whole process can last anything from 6 - 10 hours, depending on the number of radiators in your home, the age of the system and the severity of the sludge in the system.

During the process we may find more problems than originally anticipated, such as needing new parts to replace those that have been damaged beyond repair. Most Powerflush jobs can be completed in one day but some of the more severe cases may require longer.
