Underfloor Heating System Upgrade
An underfloor heating system upgrade improves the performance and controllability of an existing wet (water-based) system. It focuses on getting each heating circuit flowing correctly, modernising controls where needed, and resolving faults so rooms heat evenly at lower temperatures.
More information
What an underfloor heating system upgrade includes
An upgrade is tailored to your current system and the issues you are seeing. Work can include:
- System assessment and fault-finding across manifolds, pumps, valves and pipe circuits.
- Manifold upgrades or repairs, including flow meters, isolating valves and air vents.
- Pump checks and replacement where performance is poor or noisy.
- Actuator and wiring checks to ensure each zone opens and closes correctly.
- Thermostat and control upgrades for better zoning and quicker response.
- System balancing to match flow rates to room demand for more even heat.
- Cleaning and water quality improvements, such as flushing and inhibitor dosing where required.
- Commissioning and testing, with clear handover guidance on settings and operation.
When an upgrade is the right option
This service is a good fit if your underfloor heating is working, but not working well. Common signs include cold patches, rooms that never reach temperature, frequent airlocks, noisy pumps, stuck actuators, or zones that behave unpredictably. It is also useful when you want better control, for example adding or improving zoning, or making the system run more efficiently alongside a modern boiler or heat pump.
How the upgrade is delivered
The process starts with a site visit to inspect the manifold area, controls and visible pipework, then a structured set of checks to pinpoint restrictions, air ingress, control issues or circulation problems. You will then receive a clear scope of works, with options where there is more than one sensible approach. Once approved, the system is isolated and drained as needed, components are repaired or upgraded, then the system is refilled, purged, balanced and tested zone by zone.
After the upgrade: getting the best results
After commissioning, you will get practical guidance on thermostat settings, warm-up expectations and how to avoid common issues like over-adjusting flow rates. Where relevant, follow-up checks can fine-tune balancing after the system has run through normal daily use. Ongoing maintenance, such as periodic checks of the manifold, pump operation and inhibitor levels, helps keep performance stable over the long term.
