Power flushing in Bow: what we see
Older heating systems in Bow’s terraces and some ex-council blocks can hold years of sludge, especially where a new boiler went onto old radiators. Cold patches at the bottom of radiators, banging noises and black water when bleeding are the usual signs. The free survey checks whether power flushing suits the system.
What power flushing can do
A power flush circulates cleaning fluid through the system at high flow to lift sludge and debris. Where contamination is the problem, it can help radiators heat evenly and improve circulation.
It does not repair worn or damaged parts, and results depend on the system’s condition.
Keeping the system clean
After cleaning, inhibitor protects the system, and a magnetic filter collects debris that can be cleaned out at each service.
Fitting a new boiler? The system must be cleaned to the manufacturer’s requirements. See boiler installation in Bow.
