Power Flushing · Leicestershire
Cold Radiators?
Bring Your Heating
Back To Life.
Years of sludge, rust and debris drag your heating efficiency through the floor. A proper power flush restores full heat, protects your boiler and extends the life of every component.

Service Overview
Power Flushing:
The Brief, In Plain English.
What It Is
High-velocity, chemically assisted flush of the entire heating system, radiators, pipework, boiler and underfloor, removing sludge, rust and limescale.
Who It's For
Anyone with cold spots on radiators, slow warm-up times, noisy boilers, or planning a boiler replacement that needs the system clean first.
When You Need It
Cold patches on radiators, sludge in the system, planning a boiler replacement, or systems over 10 years old that have never been flushed.
Why It Matters
A new boiler fitted to a dirty system is a warranty void waiting to happen, and the sludge will kill it within years. Flushing now saves thousands later.
What Happens If You Wait
The Cost Of
Doing Nothing.
Black sludge from rust and debris is the silent killer of central heating. It coats the inside of every radiator and quietly destroys the boiler.
Risks Of Ignoring It
- →Cold spots, radiators only heating from the top.
- →New boiler warranty void from inadequate system protection.
- →Pump failure from blocked flow.
- →Heat exchanger damage in modern condensing boilers.
Common Mistakes Customers Make
- ×Adding inhibitor to a dirty system, useless without flushing first.
- ×Bleeding repeatedly without addressing the sludge causing the issue.
- ×Installing a new boiler without flushing the old system, voids warranty.

Why It's Worth It
What You
Actually Get.
Restored Heat Output
Cold radiators warm to the bottom again. Rooms heat up faster, system uses less gas.

Sludge-free system means warranty stays valid and heat exchanger life is extended.
Magnetic Filter Fitted
Includes installation of a magnetic system filter to protect the work going forward.
Inhibitor Dosed
Fresh corrosion inhibitor protects the system for years after the flush.
Before/After Testing
Pre and post-flush temperature readings prove the result.
Fixed Price
Based on number of radiators, no hourly creep, no surprises.

Ask Yours
How long does it take?
+
A typical 10-radiator domestic system takes 4–6 hours. Larger systems can take a full day; complex commercial systems are quoted on inspection.
How often should I have it done?
+
Once every 5–7 years for an average system, or whenever installing a new boiler. Annual inhibitor checks extend intervals significantly.
Is it messy?
+
No, fully contained. Floors protected with sheeting, equipment self-bunded, and the site swept and left as we found it.
Will power flushing damage old radiators?
+
No, we use controlled pressure and chemical inhibitors safe on older systems. Pre-flush inspection identifies any fragile components first.
How do I know if my system needs flushing?
+
Cold spots on radiators, slow warm-up, noisy boilers, brown water from bleeds, or planning a boiler swap, all clear signs sludge is present.
What does power flushing cost?
+
Most domestic flushes are priced per radiator on a fixed basis, no hourly creep. Magnetic filter and fresh inhibitor included as standard.
Will it really fix my cold radiators?
+
In the vast majority of cases yes. Before/after temperature readings prove the result; any persistent cold spot is investigated as a separate fault.
Does power flushing void my boiler warranty?
+
Quite the opposite, manufacturers require system cleanliness for warranty validity. A documented flush is often essential to keep cover in place.
