Why System Flushing is Essential for Your Heating System
Over time, central heating systems accumulate sludge and debris, leading to reduced efficiency and potential breakdowns. Regular system flushing removes these contaminants, ensuring
-
Improved energy efficiency
-
Extended system lifespan
-
Reduced risk of costly repairs
- Enhanced heating performance
Our Advanced System Flushing Method
At The Heat Network, we don’t just follow one method—we combine the best of both. By using Thoroughflush and MagnaCleanse together, we remove more sludge, rust and debris than either system alone.
This dual approach gives your heating system a powerful clean that restores efficiency and helps prevent future blockages.
How We Do It
What is Thoroughflush?
Thoroughflush uses your home’s mains water pressure to flush out radiators one at a time, without chemicals or disrupting the system layout. It’s quick, clean and highly effective at shifting sludge and debris from individual radiators and pipework.
What is MagnaCleanse?
MagnaCleanse uses a powerful magnetic filter to extract metallic sludge (magnetite) while circulating water through the system. It’s ideal for deep cleans—especially when used alongside a chemical cleaner and radiator agitator tool.
Why We Combine Both
Using Thoroughflush on individual radiators gives us full control and precision. Adding MagnaCleanse allows us to pull out fine debris and magnetic sludge during circulation. Together, they deliver:
-
Faster heat-up times
-
Reduced boiler strain
-
Lower energy bills
-
Longer system life

How do I know if my system needs flushing?
Look out for these common signs:
Cold patches on radiators
Noisy boiler or pump
Radiators heating slowly (or not at all)
Dirty brown or black water when bleeding radiators
Boiler locking out or heating bills creeping up
If you’ve got any of these, your system may be struggling with internal sludge.
Are Thoroughflush and MagnaCleanse safe for older systems?
Yes — in fact, they’re safer than old-style power flushes. Both methods use lower pressure and gentler agitation, making them ideal for ageing pipework and radiators.
Will flushing my system fix my heating issues?
If sludge is the root cause — absolutely. A proper system flush can restore flow, balance radiator heat, reduce boiler strain, and bring your heating back to life.
If there are other faults (like failed valves or airlocks), we’ll diagnose those during the visit and advise on the best fix.
How long does the process take?
Most homes take 3–6 hours, depending on the number of radiators and how blocked the system is. We’ll always give you a time estimate upfront.
Will it be messy?
Not at all. Our equipment connects cleanly to your system with no mess or water on the floor. Everything is contained — just cleaner radiators and clearer pipes by the end.
What’s included in the flush?
Pre-flush system inspection
Full system flush with Thoroughflush and/or MagnaCleanse
Chemical inhibitor added after to protect against future build-up
Optional magnetic filter install (recommended)
How much does a flush cost?
We price transparently based on the number of radiators and any extras (e.g. filter install). No hidden fees. Just get in touch for a fixed price.
How often should I flush my heating system?
We recommend every 5–7 years, or when fitting a new boiler. If you’ve never had one done, now’s the time — it’ll improve performance and protect your system investment.
What areas do you cover?
We cover Dunfermline, Kirkcaldy, South Queensferry, Lochgelly, Broxburn, and surrounding areas. If you’re unsure, just give us a ring.
