When to hire a specialist?
If your radiators are cold at the bottom and hot at the top, this is a sign that your system needs power flushing. Such malfunctions are usually caused by excess debris buildup like sludge and rust.
The older your system, the higher the chances it needs a professional flush to restore its original power.
Benefits of power flushing
Cleaning contaminants has an instant impact. You can expect your boiler to heat up faster and run more quietly than before. By doing this, you’ll lower your energy bills and enjoy higher temperatures.
After 3 to 4 hours, the debris will be gone for good, allowing clean water to flow freely again.
Professional Norstrom Proflush Equipment
We use a professional Norstrom Proflush machine with a high flow rate. The unit is filled with a powerful descaling product that removes blockages without causing harm to pipes. Finally, we add a corrosion inhibitor for future protection.
How to tell if your system actually needs a flush
Cold spots at the bottom of a radiator, a boiler that’s noisier than it used to be, or rooms that take longer to heat up are classic signs of sludge and rust building up inside your central heating system. Left alone, this debris reduces efficiency, strains the boiler’s pump and heat exchanger, and shortens the system’s working life.
A power flush forces a fast-moving, chemically treated flow through the whole system to break down and remove that build-up, restoring even heat distribution and often making a real difference to your heating bills. It’s carried out by our gas engineers and finished with a corrosion inhibitor to slow the problem returning.

Frequently Asked Questions
With time, the water that runs through your boiler, radiators, and heating pipes will start leaving some waste products behind. These include rust, dirt, and other particles, which coagulate together to form a mud-like substance, commonly referred to as “sludge”.
As your radiators grow older, the metal will slowly start to break down. This process is called corrosion and can significantly damage your heating system if left unattended.
The power flushing unit will be connected directly to your central heating system, so you won’t have to drain your radiators or remove them from the walls. The whole procedure will normally take anywhere between 3 to 4 hours to complete.
In a clogged heating system, the water is not being pumped out efficiently. This puts more pressure on your system as it struggles to maintain the normal flow of water, producing unpleasant noises. Power flushing should take care of the problem.
Regular pump failures are a strong indicator of debris in the system. You need to power flush your system as soon as possible to prevent permanent damage to the pump and boiler.
This depends on your heating system. However, a thorough power flush every 5 to 6 years should keep your boiler, radiators, and pipes in tip-top shape and prevent sludge buildup.
