Powerflushing Leicester
Cold radiators?
Let's get the heat moving.
Professional central heating system cleaning for homes across Leicester and Leicestershire. Remove sludge, improve circulation and get your heating working as it should.
Instant price
How many radiators?
That's pretty much all we need to give you an instant guide price.
Count the radiators and heated towel rails in your home, then use the + and − buttons.
Build your price.
Start with the number of radiators in your home.
What type of pipework do you have?
This doesn't change the instant price here — it helps us know how we'll approach the job.
Do I need a powerflush?
Your heating usually gives you clues.
You don't need to complete a questionnaire. These are simply the common signs we look for when deciding whether system contamination could be part of the problem.
Radiators cold at the bottom
A common sign of deposits settling inside the lower part of a radiator.
Black or dirty system water
Dark heating water can indicate corrosion products circulating around the system.
Slow or uneven warm-up
Some radiators getting hot while others struggle can point towards poor circulation.
Noisy or troublesome heating
Circulation problems and contamination can contribute to noise and recurring system issues.
Worth knowing
Not every cold radiator needs a powerflush.
Cold radiators and poor circulation can be caused by sludge — but they can also be caused by air, balancing, valves, pumps, controls or another heating fault.
That's why we'd rather understand what your heating is doing than automatically recommend a system clean.
If contamination is the problem, we'll clean it. If it isn't, we'd rather point you towards the actual fault.
It's to get the heating working properly.
Powerflushing explained
What's actually inside the system?
Over time, corrosion inside a wet central heating system can produce magnetite and other deposits.
That material can settle inside radiators and restrict the movement of water through the heating system.
A powerflush uses specialist equipment, water and cleaning chemicals to loosen and remove contamination rather than simply leaving it circulating through the boiler and radiators.
Once cleaning is complete, the system is refilled, protected with inhibitor, checked and balanced.
What happens
Cleaning the system properly.
It isn't simply a drain and refill. We work through the heating system to remove contamination and get the water circulating properly again.
Check the system
We look at the heating, circulation and condition of the system before starting the clean.
Connect the equipment
Specialist flushing equipment is connected to circulate water and cleaning chemicals through the heating system.
Work through the radiators
The system is worked through methodically to help loosen and remove accumulated deposits.
Remove contamination
Dirty water and loosened debris are flushed out rather than left circulating around the system.
Protect & balance
Inhibitor is added, the heating is checked and the system is balanced before completion.
8mm & 10mm systems
Got microbore?
That's okay.
Microbore heating systems can still be suitable for powerflushing, but the method needs to suit the smaller pipework.
Heat adapts the flushing process for 8mm and 10mm systems rather than treating them exactly like standard 15mm pipework.
Why Heat Leicester
Heating engineers first.
Flushing machine second.
The useful bit isn't owning the machine. It's understanding why the heating isn't working properly in the first place.

Not sure?
Tell us what the heating is doing.
You don't need to diagnose the heating system yourself.
Tell us which radiators aren't heating, whether they're cold at the top or bottom and anything else you've noticed.
We'll help work out whether system cleaning is the sensible next step.
