A power flush removes the magnetite sludge, rust and scale that block radiators, wear out pumps and damage heat exchangers. Carried out to BS 7593:2019, with inhibitor dosed and a magnetic filter fitted.
Adept Heating power flushes central heating systems across Bolsover, Chesterfield, Dinnington, Killamarsh, Kiveton Park, Mosborough, North Anston, Rotherham, South Anston and Worksop. Call 07519 665062.
So you can see what is actually in it, before and after.
A dedicated high flow pump connected to the system.
At high flow, reversing the flow direction repeatedly to shift settled deposits.
Individually, agitating where needed, so nothing gets skipped, until the water runs clear.
Corrosion inhibitor to BS 7593:2019 and a magnetic system filter fitted if there is not one already.
Rebalance the system, check it heats across every room, and give you a written record for your boiler warranty.
A chemical flush adds cleaner, circulated by the system's own pump, then drains it. It is cheaper and quicker, and fine for a system in reasonable condition or as part of a boiler swap on a newer system, but it will not shift heavy sludge.
A power flush uses a dedicated high flow pump with flow reversal and removes deposits a chemical flush cannot. That is the right answer for an older, dirty or repeatedly problematic system, and it is often required before a manufacturer will honour the warranty on a new boiler fitted to an old system.
A magnetic filter is not a cleaning method, it is a prevention method. It catches magnetite continuously and is emptied at each service. We test the system water and tell you which of the three your system actually needs, because there is no point paying for a power flush on a system that only needs a chemical clean.
Qualified engineers, a clean job and a fixed written price agreed before we start. We stand behind everything we fit.
It depends on the number of radiators and the state of the system, which is why we test the water first rather than quoting blind. Ring and tell us how many radiators you have and what they are doing, and we will tell you what is likely involved.
Most average houses are a few hours. A badly sludged system can take a full day.
If the existing system is dirty, yes. Most manufacturers require the system to be cleaned and a filter fitted for the warranty to stand. Fitting a new boiler to a sludged system is the quickest way to damage a new heat exchanger and have the claim refused.
If they are cold at the bottom because of sludge, yes. If they are cold at the top it is air, and bleeding fixes that. If one radiator alone is cold it may be a stuck valve or the system needing balancing. We diagnose it before quoting anything.
Not routinely. A system with a filter, correctly dosed with inhibitor and checked annually, should not need flushing again for many years, if ever.
Call 07519 665062 and we will test the system water and tell you whether it needs a flush.
