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.
