If your underfloor heating system is 20+ years old, chances are itβs not performing how it should.
We were recently called to a property in Budleigh Salterton with a 28-year-old Nu-Heat underfloor heating system that wasnβt heating evenly and had slow warm-up times.
Older underfloor systems can suffer from:
β’ Sludge and magnetite build-up
β’ Blocked loops
β’ Poor flow rates
β’ Unbalanced circuits
β’ Inefficient pump performance
β’ Reduced heat output
Instead of replacing the system (which would be extremely disruptive and costly), we carried out a full professional power flush, system balance, and health check to restore performance.
π§ What We Did
β Connected professional high-flow power flushing equipment
β Carried out chemical clean to break down 28 years of sludge build-up
β Flushed each underfloor heating loop individually
β Cleared blockages and restored circulation
β Refilled with fresh inhibitor protection
β Balanced all manifold circuits for even heat distribution
β Completed full thermal imaging before & after checks
Thermal imaging clearly showed improved heat spread across the floor after flushing and balancing.
π‘ Why Underfloor Heating Needs Maintenance
Underfloor heating systems are often forgotten because you canβt see them. But they still require maintenance β especially older systems.
Without servicing:
β’ Sludge restricts flow
β’ Pumps work harder
β’ Energy bills increase
β’ Rooms heat unevenly
β’ System lifespan reduces
A power flush and balance can dramatically improve efficiency and comfort β often without the need for expensive upgrades.

β‘ Is Your Underfloor Heating System Underperforming?
If your floors take ages to warm up, certain rooms feel cooler, or your system hasnβt been serviced in years β it may just need a professional clean and balance.
Restoring performance is often far cheaper than replacing the system.
