Underfloor Heating Installation & Upgrades

Underfloor heating provides efficient, even heat and a clean, unobtrusive finish for modern living spaces. At Heatworks Plumbing and Heating, we design and install underfloor heating systems across South Wales, delivering comfortable, energy-efficient heating tailored to each property.

Whether you’re renovating, extending, or building from scratch, we provide properly designed systems that integrate seamlessly with your heating setup.

Wet Underfloor Heating Systems

We install water-based underfloor heating systems across Bridgend, Port Talbot, Neath, Swansea and Cardiff.

Wet underfloor heating connects to a central heating system and is suitable for whole-house heating, extensions, renovations and new-build properties.

Wet underfloor heating offers:

  • Even and consistent heat distribution
  • Lower operating temperatures
  • Improved heating efficiency
  • Compatibility with boilers and heat pumps
  • Independent temperature control for different zones
  • Clear walls and floorspace without radiators

Every system is designed around the property, its heat requirements and the proposed floor construction.

Underfloor Heating Design & Installation

Underfloor heating only performs properly when it is designed and installed correctly. We carry out detailed assessments to ensure the system provides consistent comfort without unnecessary energy use or overheating.

Our installation process includes:

  • Property and floor construction assessment
  • Heat loss calculations
  • Pipe layout design and zoning
  • Manifold selection and positioning
  • Integration with the existing heating system
  • Pressure testing and commissioning
  • Heating control setup

We work with homeowners, builders, architects and other trades to ensure the underfloor heating is installed at the correct stage of the project.

Where required, the underfloor heating can be designed as part of a complete central heating installation.

Underfloor Heating for Boilers & Heat Pumps

Wet underfloor heating can operate with modern boiler systems and air source heat pumps.

It works particularly well with heat pumps because underfloor heating can provide comfortable room temperatures while operating at lower flow temperatures.

A properly designed system can:

  • Improve heating efficiency
  • Provide consistent heat throughout the room
  • Reduce reliance on high flow temperatures
  • Improve comfort in open-plan areas
  • Support future heating system upgrades

The heat source, pipe spacing, floor finish and required room temperature must all be considered when designing the system.

Underfloor Heating for Existing Homes

Underfloor heating can be installed in some existing properties, although suitability depends on the floor construction, available build-up height and the wider heating system.

Before recommending an installation, we assess:

  • Existing floor construction
  • Available floor height
  • Insulation levels
  • Heat loss from the room
  • Existing boiler or heat source
  • Required heating output

Where a traditional in-floor system is unsuitable, we will explain the available options clearly.

New Builds, Renovations & Extensions

Underfloor heating is well suited to:

  • New-build properties
  • Home extensions
  • Full property renovations
  • Open-plan living spaces
  • Kitchens and bathrooms
  • Self-build and development projects

We can integrate underfloor heating into an existing heating system or design it as part of a complete new installation.

For larger renovation projects, we can also coordinate the heating work alongside our bathroom installation, kitchen installation and general plumbing services.

Underfloor Heating Controls & Zoning

Correct heating controls allow different rooms or areas to be managed independently.

A zoned underfloor heating system can help:

  • Maintain different temperatures in different rooms
  • Prevent unnecessary heating
  • Improve comfort throughout the property
  • Match heating times to how each room is used
  • Improve overall system efficiency

Controls are selected and configured as part of the system design.

Designed for Whole-Home Efficiency

Underfloor heating works best when it is designed as part of the property’s complete heating system. We assess heat loss, insulation levels, floor construction, room layouts, zoning requirements and controls before recommending the most suitable setup. Where appropriate, we can also consider how MVHR ventilation systems may support a more comfortable, energy-efficient and well-balanced home. By correctly sizing each zone and coordinating the heating, controls and ventilation, we can deliver consistent warmth and reliable performance throughout the property.

Underfloor Heating FAQs

Is underfloor heating suitable for existing homes?

Yes, although suitability depends on the existing floor construction, available build-up height, insulation and required heating output. We assess these factors before recommending a system.

Can underfloor heating work with my existing boiler?

In many cases, yes. The system may require suitable controls, a manifold and adjustments to operate at the correct flow temperature.

Does underfloor heating work with an air source heat pump?

Yes. Underfloor heating is particularly suitable for heat pumps because it can provide effective heating at lower operating temperatures.

Is underfloor heating efficient?

A properly designed system can operate efficiently at lower temperatures while providing consistent heat throughout the room.

Can different rooms have separate temperature controls?

Yes. Underfloor heating can be divided into zones so individual rooms or areas can be controlled separately.
