Underfloor Heating

Underfloor Heating Installation (Wet System)

Wet underfloor heating is a water based heating system fitted beneath your floor to provide steady, even warmth at lower flow temperatures than many radiators. This service covers the design and installation of a wet underfloor heating system that suits your property layout, heat source and floor build up, then commissioning it so it performs as intended.

More information

What wet underfloor heating installation covers

A complete, end to end installation designed for comfort, efficiency and dependable day to day control.

  • System design and layout planning (pipe spacing, circuit lengths and zoning)
  • Manifold selection and positioning
  • Pipe installation to suit your floor build up (screed or retrofit style solutions)
  • Connection to your boiler or heat pump
  • Pumps, mixing controls and actuators where required
  • Thermostats and wiring coordination for room by room control
  • Pressure testing before the floor is closed up
  • Filling, flushing and commissioning
  • Balancing and temperature optimisation
  • Handover guidance on controls and how to run the system efficiently

When this service is most suitable

Wet underfloor heating is a strong fit when you want consistent warmth and a cleaner look without wall radiators.

  • New builds, extensions and full renovations
  • Kitchen, lounge and open plan refurbishments
  • Bathroom and ground floor upgrades
  • Landlord improvements where reliability and running efficiency matter
  • Small commercial spaces needing even heat and clear zoning

How the installation is delivered

Work usually starts with an assessment of the floor construction, insulation levels, room sizes and your heat source. The system is then designed around sensible zones, practical manifold placement and clear pipe routes.

Installation includes fitting the manifold, laying pipe circuits, pressure testing, and coordinating with other trades before screed or flooring goes down. Once connected, the system is commissioned, balanced and set up so flow temperatures and controls match how you use the space.

After installation: commissioning, optimisation and support

After commissioning, you get guidance on warm up times, thermostat settings and how to run the system efficiently. If needed, follow up visits can fine tune balancing and controls once the building fabric has dried out and the space is in regular use.

Support is also available for fault finding and repairs, such as flow issues, actuator faults, control problems or uneven heating.

Frequently Asked Questions

Can wet underfloor heating work with my existing boiler?
In many homes, yes. The system is designed so flow temperatures and controls suit your boiler, often using a manifold with the right mixing and pump arrangement. A site assessment confirms compatibility and the best approach.
Is wet underfloor heating suitable for a heat pump?
Yes, it is often an ideal match because underfloor heating runs efficiently at lower water temperatures. The design focuses on correct pipe spacing, insulation and zoning so the heat pump can operate effectively.
How disruptive is a wet underfloor heating installation?
It depends on whether the floors are already finished. In renovations it usually involves lifting floors or building up the floor level, so it is best planned alongside other building work. You will be advised on the least disruptive option for your property.
What floor finishes can be used with wet underfloor heating?
Most finishes can work, including tile, stone, engineered wood and some vinyl and carpet systems. The key is choosing materials with suitable thermal resistance and using the correct underlay and adhesives. Guidance is provided based on your chosen finish.
Why is commissioning and balancing important?
Commissioning proves the system is safe, filled correctly and free from air and debris. Balancing ensures each circuit gets the right flow so rooms heat evenly and controls respond properly. It also helps reduce running costs and avoids hot and cold spots.
