Signs you may need a power flush
- Radiators cold at the bottomSludge settles at the bottom of radiators and stops them heating.

How it works
What a power flush does
We connect a power flushing machine to your heating system and push water and cleaning chemicals through the radiators at high flow.
That shifts the sludge and rust, which we flush out before the system is refilled.

Questions
Power flushing: your questions
How do I know if I need one?
If radiators are cold at the bottom, slow to heat or the water is dark when you bleed them, sludge is a likely cause. Tell us what you’re seeing when you book and we’ll talk it through when we call.
When will I know the price?
We can often give you a quote over the phone. If the job is urgent, or we can’t price it over the phone, we’ll quote when we visit. There’s no VAT to add.
