Power Flushing and Descaling for Central Heating Systems & Boilers

Limescale, sludge, and rust contribute to leaks and blockages. Dirty water in your pipes can cause heating problems and reduce efficiency.

Breakdowns are caused by clogged boilers and pumps. 87% of boiler breakdowns are caused by dirty water in your heating system.

By clogging up your boiler, radiators, and pipes, you create cold spots that make your heating inefficient.

The boiler, pipes and radiators will be thoroughly cleaned and sludge replaced with clean water using a machine and a three-step chemical process.

Your boiler, radiators, and pipes will function much better and more efficiently after the Powerflush.

If the system is not properly maintained, sludge, rust, and debris can build up in the boiler, pipework, and radiators. Whenever there are blockages in the heating system, heat cannot reach all areas because the flow of water is restricted. Heat is lost, and money and energy are wasted.

As a result, circulation throughout the system will become very slow, resulting in radiators taking a long time to heat up, and eventually stopping altogether causing a boiler breakdown. The cost of repairs is extremely high.

A typical cold spot in the radiator can be seen here. The radiator was evenly heated after the powerflush. Our customers would not be able to receive such a thorough powerflush without this technology.

An effective way to remove rust from your heating system and boiler is powerflushing. Water, chemicals, powerflush equipment and an experienced plumber are used to remove the rust and sludge from your central heating. The flow of the machine is reversed from time to time using special three-way valves attached to the flushing pump. This is an extra step to help clean the pipes and radiators to remove cold spots.

Assume that. There is a problem with your pump or it has been stuck. Due to the lack of circulation, the water in the heat exchanger will boil very quickly. Some older boilers don’t turn the gas off immediately when the thermostat is turned off. Modern condensing boilers are equipped with more sensitive thermostats that shut down the boiler flame quickly.

The second one. In some cases, either the main flow or return pipework, or one of the water ways in the boiler heat exchanger is completely or partially blocked, so the water in the boiler begins to boil and make steam again. Thus, the popping, hissing, and banging.

A powerflushed system can produce a surprising amount of rust and radiator sludge, in all shapes and sizes. Despite popular belief, most of the sludge you see does not come from your boiler. It is generally believed that cast-iron heat exchangers in non-condensing boilers (boilers installed before 2005) are not prone to rusting. Since radiators are made of mild steel, the bulk of your rust or sludge comes from them.
