Underfloor Heating Maintenance: How to Keep Your System Running Efficiently for 20+ Years

Underfloor heating is often described as a fit-and-forget system, and while it is true that it requires far less maintenance than traditional radiators or forced-air systems, it is not entirely maintenance-free. A simple annual maintenance routine can keep your system running at peak efficiency for 20 years or more, preventing costly repairs and ensuring consistent comfort. This guide covers the essential maintenance tasks for both electric and water-based underfloor heating systems.

Annual Maintenance for Electric Systems

Electric underfloor heating systems require minimal maintenance, but an annual check can identify potential issues before they become problems. Start by visually inspecting the thermostat for any signs of damage or malfunction. Check that the display is functioning correctly and that all buttons or touch controls are responsive. Verify that the floor sensor is reading accurately by comparing the displayed floor temperature to an infrared thermometer reading. If there is a discrepancy greater than 2 degrees, recalibrate the sensor offset in the thermostat settings.

For WiFi-enabled thermostats, check for firmware updates through the companion app. Manufacturers regularly release updates that improve performance, add features, and address security vulnerabilities. Review the energy usage data in the app to identify any unusual patterns that might indicate a problem with the system. Compare current energy consumption to the same period in previous years to detect any efficiency degradation.

Annual Maintenance for Water-Based Systems

Water-based underfloor heating systems require more attention than electric systems due to the presence of circulating fluid. Check the system pressure on the manifold pressure gauge, which should be between 1.5 and 2.5 bar when cold. If the pressure has dropped, top up the system through the filling loop. Investigate the cause of any pressure loss, as it may indicate a leak in the system that requires professional attention.

Inspect the manifold for any signs of leakage, corrosion, or damage. Check that all flow meters are reading correctly and that the valves operate smoothly. Operate each thermal actuator manually to verify that it opens and closes fully. Listen for any unusual noises from the circulation pump, which might indicate wear or air in the system. If the pump is making grinding or whining noises, it may need to be replaced.

Descaling and Water Treatment

In areas with hard water, limescale can accumulate in the heating circuits over time, reducing flow rates and heat output. If you notice reduced flow rates or uneven heating, descaling may be necessary. This should be performed by a qualified heating engineer using a power flushing machine and appropriate chemical cleaners. After descaling, add a corrosion inhibitor to the system water to prevent future scale formation and protect the internal components from corrosion.

Thermostat Software Updates

WiFi thermostats, like any connected device, benefit from regular software updates. These updates can improve energy efficiency through better algorithms, add new features such as integration with additional smart home platforms, and address security vulnerabilities. Check for updates through the thermostat companion app at least twice per year. If automatic updates are available, enable them to ensure your thermostat always runs the latest firmware.

Seasonal Preparation

Before the heating season begins, typically in early autumn, perform a system test. Set the thermostat to 25 degrees and verify that the floor warms up within the expected time frame. Check for any cold spots that might indicate a problem with a specific circuit or heating element. For water-based systems, bleed any air from the system using the air vents on the manifold. For electric systems, verify that the RCD trips correctly by pressing the test button.

When to Call a Professional

While most maintenance tasks can be performed by the homeowner, certain situations require professional attention. Contact a qualified technician if: the system fails to heat despite power being available, the circuit breaker or RCD trips repeatedly, there are visible signs of damage to the floor surface (cracking, lifting, or discoloration), the system pressure drops repeatedly despite topping up, or there are unusual noises from the manifold or pump. SunAura Thermal provides technical support and can recommend qualified service partners in your area.

Conclusion

With proper maintenance, an underfloor heating system can provide 20-30 years of reliable, efficient service. The key is regular inspection, prompt attention to any issues, and professional servicing when needed. By following this maintenance guide, you can ensure that your SunAura Thermal heating system continues to deliver optimal comfort and efficiency throughout its long service life.
