Power flushing based in Rainhill, St Helens

Covering St Helens, Warrington, Altrincham, Hale Barns and the rest of the U.K.

Are your radiators cold at the bottom? Is your boiler working but your home is still cold? Have you noticed a decrease in the efficiency of your central heating system?

This could be happening because of a build up of sludge in your central heating system. If this is the case, you’ll need a power flush to get your heating system back to good health and efficiency. At AGL Heating & Plumbing, we have the proper experience and professional equipment needed to completely flush your system.

The Power Flush Process

A power flush is simply a process that gives your central heating system a thorough internal clean and usually improves the central heating system’s performance; which can lead to lower gas bills.

Over time some heating systems may experience poor circulation resulting in lukewarm radiators, poor hot water, increased noise and sludge build up. By ‘power flushing’ your heating system, the sludge and built up residue will be removed via inline magnetic filtration, it will make your system work more efficiently.


How does Power Flushing Work?

Because the water in a central heating system is always pumped in the same direction, iron filings, sludge, oil and grease build up within each radiator in your system. This has a detrimental effect on the efficiency of both your radiators and your boiler – in fact – your whole central heating system, reducing its life expectancy.

When a system is professionally power flushed, the system is flushed in different directions, agitating the sludge and debris, so the system can be drained of the deposits. When flushing a system, special chemicals are used to ensure the breakdown of the sludge inside the system, prior to the deposits being removed.

Power Flushing your Central Heating system can also extend the life span of your boiler and under Part L of the building regulations, it is recommended that your system be power flushed when an old central heating boiler is being replaced by a new boiler.

How we know it’s time for a power flush

At AGL Heating & Plumbing, we don’t just assume that you have a build up of sludge and rust and that it’s time for a power flush, we use professional infrared equipment to confirm that this is the case. Using the image we’ve taken as an example, you can clearly see that the radiator in question is cooler at the bottom than it is at the top. This is how we were able to tell that there was indeed a blockage in the radiator and that a power flush was necessary in this case.

Don’t just let someone tell you that you need a power flush, know for sure. Book an appointment today.
