What’s the difference between a power flush and a chemical flush?
"Power Flush vs Chemical Flush: The Ultimate Comparison"

A chemical flush and a power flush are two methods used to clean central heating systems, but they are different in terms of the process and equipment used.
A chemical flush involves the use of chemical cleaning solutions to break down and remove debris, rust, and buildup from the heating system. The cleaning solution is circulated through the system, and then drained along with the debris. This process is usually performed by a professional heating engineer.
On the other hand, a power flush uses highvelocity water to physically flush out the debris, rust, and buildup from the system. This process uses specialized equipment such as a power flushing machine and is also performed by a professional heating engineer.
Both methods are effective in cleaning central heating systems, but a power flush may be more efficient in removing heavier buildup, while a chemical flush may be better at breaking down and removing more stubborn deposits. The choice of method may depend on the individual heating system's needs and condition.
