Single Zone Water Underfloor Heating Kits

Single Zone Underfloor Heating Kits – 15m² & 20m² Wet Heating Systems

Looking for a convenient, affordable way to install water underfloor heating in a single room or extension?

Our Single Zone Water Underfloor Heating Kits provide a practical solution for adding comfortable, even floor heating to smaller domestic projects without the complexity of a multi-zone installation.

At Underfloor Heating Trade Supplies, we specialise in supplying quality underfloor heating products to professional installers, builders, heating engineers and homeowners throughout the UK.

Available in 15m² and 20m² options, our single-zone kits contain the essential heating and installation components needed to help you create a reliable, professionally installed wet underfloor heating system.

What Is a Single Zone Underfloor Heating System?

A single-zone underfloor heating system is designed to heat one room or individual heating area.

Warm water circulates through pipework installed beneath the floor, distributing heat across the floor surface to create consistent, comfortable warmth.

Unlike multi-zone underfloor heating systems, which use separate controls for different rooms, a single-zone system operates as one heating area when connected to suitable room temperature controls.

This makes single-zone water underfloor heating particularly useful for kitchens, bathrooms, conservatories, extensions and other individual rooms.

What's Included in Our Single Zone Underfloor Heating Kits?

Our kits feature quality components selected to provide a convenient solution for smaller wet underfloor heating installations.

Both sizes include:

• A-Rated Low-Energy Grundfos 3-Speed Circulation Pump – Helps circulate heated water through the underfloor heating pipework.

• Automatic Water Temperature Control Mixing Valve – Regulates the mixed water temperature supplied to the floor heating circuit.

• NovaTherm MLCP Underfloor Heating Pipe – Flexible multilayer composite pipe with an aluminium oxygen barrier, designed for compatible wet underfloor heating systems.

• Connector Cores – Provide suitable pipe connections within the heating assembly.

• 50m Edge Insulation Roll – Helps accommodate screed expansion and reduce perimeter heat loss.

• High-Grip Pipe Clips – Secure the underfloor heating pipe to suitable floor insulation before screeding.

• Pipe Reamer Tool – Helps prepare the pipe ends for correctly matched fittings.

Our kits contain the main heating components and installation accessories, helping reduce the time spent sourcing individual products.

Choose the Right Single Zone Underfloor Heating Kit

We offer two kit sizes to suit different heating requirements.

15m² Single Zone Underfloor Heating Kit

An excellent choice for smaller kitchens, bathrooms, utility rooms and compact home extensions.

Supplied with 80 metres of NovaTherm multilayer pipe, this kit provides a practical solution for heating smaller individual rooms.

20m² Single Zone Underfloor Heating Kit

Ideal for larger kitchens, dining areas, modest extensions and other appropriately designed single-room installations.

Supplied with 100 metres of NovaTherm multilayer pipe, this kit offers additional pipe length for larger heated floor areas.

The actual area covered by either kit depends on pipe spacing, the available heated floor area, room heat loss and system design.

Underfloor Heating Pipe Spacing & Floor Coverage

Correct pipe spacing is important for achieving the required heat output from a water underfloor heating system.

Closer pipe spacing may be necessary in rooms with higher heating requirements, while wider spacing may be suitable for lower-output applications.

The nominal kit sizes are based on typical installation arrangements, but the actual floor coverage can vary.

These are indicative coverage figures. Wider pipe spacing does not necessarily provide sufficient heat output for every room.

For best results, the installation should be planned using appropriate room-by-room heat-loss calculations.

Ideal for Kitchens, Bathrooms & Home Extensions

Our single-zone underfloor heating kits are particularly useful for smaller renovation and extension projects.

Kitchen Underfloor Heating

Enjoy comfortable warmth beneath your kitchen floor while reducing the need for traditional wall-mounted radiators.

Bathroom Underfloor Heating

Create a pleasantly heated floor in a correctly designed bathroom installation, using suitable controls and floor finishes.

Home Extensions

A single-zone wet underfloor heating system can provide an effective way to heat a newly constructed extension, subject to the heating system design.

Conservatories

Underfloor heating may be suitable for conservatories, although their potentially higher heat losses must be considered when determining whether the system can provide sufficient heating.

Single-Room Renovations

Our compact kits are ideal for compatible renovation projects where the floor construction can accommodate water underfloor heating pipework and screed.

Quality NovaTherm MLCP Underfloor Heating Pipe

Our single-zone kits contain flexible NovaTherm multilayer composite pipe, designed for use in compatible water underfloor heating systems.

The multilayer construction incorporates an aluminium core that provides an effective oxygen barrier, helping reduce oxygen diffusion into the closed heating system.

The pipe also offers good dimensional stability and shape retention, making it a practical choice for professional installations.

The 15m² kit contains 80m of pipe, while the 20m² kit includes 100m.

Low-Energy Grundfos Circulation Pump & Automatic Temperature Control

Each kit includes an A-rated low-energy Grundfos three-speed circulation pump and an automatic water temperature control mixing valve.

The circulation pump moves heated water around the underfloor heating circuit, helping distribute warmth evenly across the floor area.

The mixing valve regulates the water temperature supplied to the underfloor heating pipework, helping maintain suitable operating conditions.

This combination makes the kits suitable for integration into compatible heating systems when correctly designed and installed.

Thermostats & Room Temperature Control

Please note: Thermostats are not included as standard in either single-zone underfloor heating kit.

Suitable thermostat options can be selected separately when ordering.

Adding an appropriate room thermostat allows the heating system to respond to the required room temperature, helping maintain comfort and avoid unnecessary heating.

We offer a selection of compatible heating controls, including digital and programmable thermostat options.

Benefits of Single Zone Water Underfloor Heating

A correctly designed and installed wet underfloor heating system offers several advantages:

• Comfortable, even heating – Distributes warmth across the floor surface.

• Discreet installation – Heating pipework is concealed beneath the finished floor.

• Greater room layout flexibility – Reduces reliance on wall-mounted radiators.

• Convenient individual room heating – Particularly useful for extensions and single-room renovations.

• Flexible heating controls – Allows temperature control when connected to suitable equipment.

• Quality system components – Includes NovaTherm pipe, a Grundfos pump and essential installation accessories.

• Competitive installation costs – Convenient kit contents help reduce the need to source individual components separately.

Actual heating efficiency, running costs and room comfort depend on the heating source, insulation, floor construction and system design.

Free Underfloor Heating CAD Design Service

Choosing the correct underfloor heating kit involves more than measuring the floor area.

Pipe spacing, room heat loss, heating circuit length and floor construction all influence the heating performance of the installation.
