Power flushing a central heating system

A flush day in Houghton, from start to finish

We arrive first thing, which is easy when our base is in the same town. Dust sheets go down, and we check the boiler and pump before anything else, since a flush works them hard.

Next the flushing unit is plumbed in and a cleaning chemical goes into the water. It is driven round at high flow and the direction is flipped again and again, so debris lying in bends and at the far ends of radiators gets lifted out. Each radiator has its own turn with the others shut off. Dirty water goes to drain and fresh water comes in until the return runs clear.

To finish, the system is refilled and dosed with inhibitor, and a magnetic filter goes on the boiler return if one is not there already. Then we balance the radiators so heat reaches every room evenly.

Because we are local, popping back later to look at a stubborn radiator is a short trip rather than a special journey.

Houghton housing and why sludge builds up

We see the inside of a lot of heating systems round here, and the houses fall into three rough groups. Each group tends to go wrong in its own way.

Former colliery terraces

The older terraces in Houghton, Newbottle, Philadelphia and Chilton Moor were built long before anyone had central heating. When it went in, the pipes went wherever they could: along skirting boards, through solid floors, up the back of chimney breasts. Pipework buried under a solid floor cannot easily be rerouted, and its low points are exactly where black iron sludge settles. Pouring a cleaner in and leaving it will not reach that. It needs real flow, pushed both ways.

1960s and 1970s estates

Many of the estates around Shiney Row, Penshaw and Burnside have systems that were altered bit by bit over the years. A new radiator here, a replacement boiler there, perhaps a switch from a tank and cylinder to a combi. Every time the water is drained, the protective inhibitor goes down the drain with it. After decades of that, steel radiators corrode from the inside, and the pump, valves and boiler all end up breathing in the result.

Newer private estates

Newer houses around Herrington and Bournmoor usually have plastic pipe and a combi. They sludge up more slowly, but they still do, especially where nobody ever fitted a filter. A modern boiler has narrow waterways, so it does not take much debris to cause trouble.

Check it yourself first

With the heating on for half an hour, run your hand down each radiator. A hot top and a cold bottom is the sludge pattern. Then hold a jar under a bleed valve and open it a touch. Clear water is good news. Dark grey or black water means iron oxide is going round your system, and that is the evidence you want before spending anything.

New boiler on the way?

Manufacturers expect the system to be cleaned to BS 7593 and fitted with a filter before they stand behind their warranty. Cleaning at the same time as the install costs less and protects the new boiler from its first day.

Everything included in a Houghton power flush

Leave out the inhibitor or the filter and the sludge simply comes back, so we treat both as part of the job.

🧪
Water checked before we quote
We look at the colour and condition of the system water first, so you only pay for a flush if you need one.
🔄
Flow in both directions
Our flushing unit pushes cleaner round hard and switches direction to shift sludge lying in low points.
♨️
One radiator at a time
Radiators are closed off in turn so each gets full flow, including the awkward one upstairs at the back.
💧
Flushed until the return is clean
Dirty water goes to drain and fresh water goes in until what comes back is clear.
🛡️
Inhibitor on refill
The fresh water is dosed with inhibitor to slow corrosion right down.
🧲
Magnetic filter
Fitted on the boiler return so loose iron is trapped before it reaches the heat exchanger.
Boiler dead rather than sluggish?

If it has locked out or will not fire at all, you need a repair, not a flush. Our fixed price diagnosis starts from £96 with no call out fee on top, and we are only minutes away.

Houghton le Spring power flush FAQs

Honest answers, including the times a flush is not the answer.

How can I tell if my radiators need a flush? +
Put the heating on, then feel each radiator. Warm at the top and cold at the bottom points to sludge. Bleeding one into a jar confirms it: black or dark grey water is iron oxide. A boiler that fires, cuts out and fires again can be another sign.
What is the difference between a chemical clean and a power flush? +
A chemical clean uses your own pump to move a cleaner round, then drains it. That can be enough for a lightly dirty system. A power flush uses a separate, stronger pump and reverses the flow, which is what shifts sludge lying in pipes under the solid floors of older Houghton terraces.
How much is a power flush in Houghton le Spring? +
From £495 inc VAT. The final price depends on how many radiators you have and how bad the sludge is. We give you a fixed figure first, and most jobs take the best part of a day.
The pump on my system keeps packing in. Could sludge be why? +
Quite possibly. Pumps and motorised valves wear out early when dirty water runs through them. A new pump on a sludged system rarely lasts long, so it is worth cleaning the system when you replace it.
Will a flush definitely fix a cold radiator? +
If sludge is the cause, it usually does. Sometimes the real problem is a stuck valve or a radiator that needs balancing, which costs far less. We find out which it is before quoting.
Do you cover Shiney Row, Penshaw and Fence Houses? +
Yes. They are all a short drive from our base, along with Newbottle, Philadelphia, Herrington, Burnside, Bournmoor, West Rainton and Chilton Moor. The price is the same as in Houghton itself.
Is it worth flushing an old colliery terrace system, or should I just replace the radiators? +
A flush is often enough to bring old radiators back to life. If one is badly corroded or already weeping, replacing that radiator makes more sense. We will tell you which ones are worth keeping.
Can I check you are Gas Safe registered? +
Yes. Our Gas Safe number is 634641 and you can look it up on the Gas Safe Register website.
