Power Flushing
Central Heating Power Flushing in Ammanford, Swansea & Neath
If the bottom of the radiators stays cold, the system is noisy or the water that comes out is black, there is sludge in the pipework. A power flush clears it out — which restores heat output and takes the strain off the boiler and pump.
Signs your system needs a flush
Cold spots at the bottom of radiators, radiators that need bleeding constantly, banging or kettling from the boiler, and dirty black water when a radiator is bled all point to corroded sludge and scale circulating through the system.
Left alone, that debris settles in the boiler, pump and valves, which is when repairs get expensive. A flush is usually cheaper than the component failures it prevents.
What happens on the day
We connect a flushing pump to the system, work through one radiator at a time and flush with clean water and a chemical cleaner until it runs clear. Heating and hot water are tested afterwards and the radiators are balanced so heat is even throughout the house.
It is a day's work in a typical home and the heating is back on before we leave.
Aftercare that keeps it clean
Once the system is clean we add corrosion inhibitor and, where there is space, fit a magnetic filter on the return pipe to catch metal debris before it reaches the boiler.
If the pipework or radiators are too far gone to flush, we will say so honestly and quote for replacement rather than taking money for a flush that will not solve it.

Frequently asked questions
Is a power flush always necessary?
No. Sometimes a single radiator needs attention or the system only needs a chemical dose and a filter. We check the water condition and the symptoms first and recommend the smaller job where it will work.
Can a power flush damage an old system?
On a very old installation with thin or corroded pipework it can reveal weaknesses. That is why we inspect beforehand and tell you if a gentler approach or a partial flush is the safer option.
Will it reduce my heating bills?
A clean system heats more evenly and lets the boiler run closer to its design efficiency, so most homes see some improvement. It is not a promised saving, and we will not pretend otherwise.
