How to Maintain Your Underfloor Heating System Year-Round
Underfloor heating is low-maintenance by design—but “low” doesn’t mean “no” maintenance.
Whether you have an electric or water-based system, a little TLC goes a long way in maximising efficiency, preventing issues, and extending lifespan.
Annual Underfloor Heating Maintenance Checklist
1. Check Your Thermostat Settings
Ensure timers and temperature zones match your seasonal needs.
2. Visually Inspect the Manifold (Wet Systems)
Look for leaks, corrosion, or debris around valves and gauges.
3. Test Each Zone
Turn the system on for a full cycle and walk each area. Any cold patches may indicate an airlock or wiring issue.
4. Bleed the Loops (Water Systems)
If you notice gurgling sounds or uneven heat, bleed each loop to release trapped air.
5. Clean Around Sensors and Thermostats
Dust or blocked sensors can reduce heating accuracy.
Signs You May Need Professional Help
- Cold spots that don’t resolve after bleeding
- No response from thermostat or controls
- Sudden spikes in energy bills
- Water leaks near the manifold or boiler

How Often Should You Service the System?
- Water systems: Full service every 1–2 years including pressure check and inhibitor top-up
- Electric systems: Visual inspection every 1–2 years
