Underfloor Heating

Underfloor Heating Maintenance

Underfloor heating works best when the system is clean, balanced and correctly controlled. Underfloor heating maintenance is a planned service for wet (water-based) systems that checks key components, fine-tunes performance, and helps reduce the risk of cold spots, noisy operation, or unexpected faults.

More information

What underfloor heating maintenance covers

A maintenance visit focuses on the parts that affect comfort, efficiency and reliability, with clear feedback on what’s working well and what needs attention.

  • Visual inspection of the manifold, pipe connections and accessible pipework
  • Checks on system pressure, signs of leaks and air in the circuits
  • Testing pump operation and verifying correct flow through each loop
  • Flow and temperature balancing to improve even heat across rooms
  • Control checks, including thermostats, actuators and wiring centre connections
  • Basic fault-finding where performance is poor (for example, one zone not heating)
  • Practical recommendations for optimisation or repairs, if needed

When this service is most useful

This service is a good fit if:

  • Rooms are heating unevenly or you are getting persistent cold patches
  • The system takes longer than usual to warm up
  • You have noisy components at the manifold or circulation pump
  • A zone or thermostat is not responding as expected
  • You want reassurance that a new install is running correctly after the first season
  • You manage a rental or small commercial space and need predictable, reliable heating

What happens during the visit

You’ll be asked about the symptoms you’ve noticed and how the system is used day to day. The engineer will then inspect the manifold area, test key components, and take readings to confirm flow and temperatures across circuits. Where possible, the system is balanced and settings are adjusted to improve performance while keeping the low temperature benefits of underfloor heating.

After the maintenance check

You’ll get a clear summary of findings and any next steps, prioritised by urgency. If a repair or part replacement is advised, you can expect straightforward options and an explanation of the impact on comfort, running costs and reliability. Ongoing maintenance helps keep heat output consistent and can extend the working life of pumps, valves and controls.

Frequently Asked Questions

How often should wet underfloor heating be maintained?
For most homes and small commercial systems, an annual check is sensible, ideally before the heating season. If you notice cold spots, noise, or slow warm-up, it is worth booking sooner.
Will maintenance fix cold spots in the floor?
Cold spots are often caused by poor balancing, air in the system, or a control issue, all of which can be checked during maintenance. If the cause is a blockage or a failed component, you’ll be advised on the repair needed.
Do you need access to every room?
Usually access to the manifold, thermostats and the main zones is enough to test operation and make adjustments. If specific rooms are underperforming, access helps confirm temperatures and zone response.
Can you maintain both underfloor heating and radiators on the same system?
Yes, many properties have a mixed system. Maintenance can include checks that the underfloor side is correctly set up for low temperatures and that blending valves and controls are operating as intended.
Is underfloor heating maintenance disruptive?
It is typically low disruption, with most work done at the manifold and controls. Heating may be turned on and off during testing, and some zones may be adjusted while balancing is completed.
