A clean system experiences fewer problems, reducing the likelihood of inconvenient and expensive emergency repairs.
Certain situations make powerflushing particularly important for maintaining your heating system's health. If you're installing a new boiler, a powerflush beforehand is essential – it protects your investment by ensuring dirty water won't damage the new components. Most boiler manufacturers actually require a system flush to validate their warranty. After years of use without proper maintenance, systems accumulate significant contamination that reduces efficiency and causes problems. If you've noticed any warning signs like cold spots, noisy pipes, or increased energy bills, it's time for a powerflush. We also recommend powerflushing before winter to ensure your heating performs reliably when you need it most.


We follow a thorough, professional approach to ensure your heating system is completely cleaned and protected. Our engineers start by assessing your system's condition and explaining what's needed. We then connect specialist powerflushing equipment to your system and circulate cleaning chemicals at high velocity to break down and remove all sludge and debris. Each radiator is individually flushed to ensure thorough cleaning throughout. After flushing, we add corrosion inhibitor to protect your system, test everything is working properly, and provide advice on maintaining your system's cleanliness. Most powerflushing jobs are completed within a day, causing minimal disruption to your routine.
