Power flushing
A power flush uses specialist equipment to circulate water and cleaning chemicals at controlled conditions. Suitability depends on system condition, access and professional assessment.
Compare before deciding
Power flush or chemical flush: which does my heating system need?
Neither method is automatically right for a symptom or water result. The suitable approach depends on the system, the verified problem, condition, materials, manufacturer guidance and the limits of the proposed work.
Chemical cleaning
Chemical cleaning may use circulation or dwell time without the same pumping arrangement. The product, dose, compatibility, disposal and commissioning requirements still matter.
A controlled decision
Use findings → recommendation → quotation → informed customer decision. Ask what evidence supports the recommendation, what is included, what risks or exclusions apply and how the system will be checked and protected afterwards.
