What is power flushing? 


A power flush is a chemical solution that is used for cleansing of the central heating system; this is done by removing harmful elements such as sludge deposits, rust and other debris that result into blockage of this system. 

Power flushing is the process of cleansing the central heating system as the contaminants reduce the efficiency of the central heating system. A system blockage may also result in contaminating the water by including unwanted dirt such as rust into the water.

If you notice problems with your central heating, you man benefit from a power flushing service.

Sludge (rust that accumulates to become mud like) can cause the breakdown of the system, blockage and even reduce the efficiency of the system.

When Do You Need A Powerflush?

A power flush is required depending on the type of system and if you regularly clean the system. If you regularly do servicing and maintenance of your central heating system, then a power flush is required 5-6 years. 

For example, if your boiler contains heat exchangers that are made of copper, then it is prone to rust and corrosion, thus you require a power flush to be done more often than the recommended period of 5-6 years if the heat exchanger is made of stainless steel.

How Does a Powerflush Work?

Power flush works by the engineer connecting the pipes to the central heating system. Depending on whether the boiler is a combi or system, the pump will be connected in different parts of the central heating system. 

That is, for system boilers the pump is connected at the circulation pump while if the system is a combi, then the pump will be connected at the head pump. The pump is then used to push out chemical solutions to the radiator and boiler via the pipes.

Signs You Need a Powerflush

There are common signs that one should look out for to determine whether their system requires power flush or not, such signs include:

  • Presence of cool patches on the radiator  
  • Excessive noise at the bottom of the radiator  
  • When the radiator takes longer time than expected to heat cloudy tap water
  • When you notice your radiator is struggling to heat up
  • When the pipes are hot, but the radiator is cold
  • If the boiler often shuts down are require rebooting 
  • When no water escapes when the radiator is bleed
  • Small noisy leaks in either the radiator or the boiler
  • Production of discoloured water when the radiator is bleed

Benefits of a power flush

  1. Helps the radiators to warm up water at a faster rate
  2. Helps to save on both energy and money
  3. It lessens the chances for either the boiler or the radiator to break and thus prolong their life
  4. Radiators and boilers become hotter and quitter

In conclusion, if you observe the above signs in your central heating system, then you need to seek professional help. An engineer may suggest that a power flush is the best solution. 

Sometimes it may be more cost-effective to replacing the system instead of requesting for a power flush; it is thus essential you consult a professional to get the best advice for your heating system.
