In-Screed Underfloor Heating Kits
New builds, extensions and new screeded floor constructions.
UFH pipe is fixed to the floor build-up before screed is laid, creating a strong wet underfloor heating system for total room heating.
Each kit is designed to bring together the main components required for a typical water underfloor heating installation.
Suitable for Different Floor Builds
Choose in-screed kits for new floors, overlay kits for low-profile retrofits, or routed board kits for timber and chipboard floor constructions.
Even Room-Wide Warmth
Water underfloor heating spreads heat across the floor area, helping reduce cold spots and improving comfort throughout the room.
Low-Profile Options Available
ThermRite PRO overlay kits are designed for projects where a screeded floor build-up is not practical or where floor height needs to be reduced.
Compatible with Modern Heating Systems
Wet UFH systems are commonly used with boilers, heat pumps and low-temperature heating designs when specified and installed correctly.
Convenient Kit Sizes
Select the kit size that best matches the heated floor area, helping simplify product selection for installers and homeowners.
What’s Included in a Complete Underfloor Heating Kit?
A complete water underfloor heating kit normally includes pipework, fixings or routed panels, manifold components, connector cores and pump pack options. The exact contents depend on the kit type, floor construction and selected kit size.
Component
Purpose
Typical Use
UFH Pipe
Carries warm water through each floor heating circuit.
Used in all water underfloor heating systems, with pipe size depending on the chosen kit type.
Overlay Panels or Boards
Hold pipe in position and help support heat transfer through the floor build-up.
Used in ThermRite PRO overlay kits and HeatBoard Thermo routed board systems.
Pipe Clips or Fixings
Secure UFH pipe before screeding or covering.
Commonly used in in-screed heating kits where pipe is fixed before the screed is laid.
Manifold Components
Distribute water to each pipe loop and allow the system to be balanced.
Used on manifold-based water underfloor heating systems with multiple circuits.
Connector Cores
Help connect UFH pipework to the system components.
Supplied according to the manifold and pipe circuit requirements of the kit.
Pump Pack or Temperature Control Unit
Helps circulate water and regulate the flow temperature through the underfloor heating system.
Commonly fitted with manifold-based wet UFH systems, depending on the selected kit.
Compare ThermRite Underfloor Heating System Types
The best underfloor heating kit depends on the floor structure, available build-up height, insulation levels, heat loss and final floor finish. The table below explains where each system is commonly used.
System Type
Typical Floor Build-Up
Best Application
In-Screed UFH Kits
Pipe fixed before a screed layer is installed.
Best for new builds, extensions and projects where a new screeded floor is being created.
16mm Overlay UFH Kits
Slim routed overlay panels with 12mm pipe.
Best for low-profile retrofit projects where floor height is restricted.
20mm Overlay UFH Kits
Routed foil-faced overlay panels with 16mm pipe.
Best for renovations and retrofit projects requiring a practical overlay system with strong heat transfer.
HeatBoard Thermo UFH Kits
Routed chipboard panels with UFH pipe and cement cover boards.
Best for timber floor projects, chipboard floor build-ups and fit-from-above routed board installations.
Best Uses for Complete Underfloor Heating Kits
New Build Homes
In-screed UFH kits are a strong choice for new homes where the floor build-up can be designed around the heating system from the start.
Home Extensions
Underfloor heating kits are commonly used in kitchen extensions, open-plan spaces, garden rooms and living areas.
Renovation Projects
Overlay UFH kits are ideal where an existing floor is being upgraded and a low-profile floor build-up is required.
Timber Floor Installations
HeatBoard Thermo kits are suitable for projects where routed chipboard panels are required as part of the floor deck and heating system.
Trade Installations
Complete UFH kits help installers, plumbers and heating engineers select compatible components for common floor heating projects.
Frequently Asked Questions
What is a complete underfloor heating kit?
A complete underfloor heating kit is a packaged wet UFH system designed to include the key components needed for a typical installation, such as pipe, boards or fixings, manifold components and pump pack options.
Which underfloor heating kit is best for a new build?
In-screed underfloor heating kits are usually best for new builds and new floor constructions where UFH pipe can be installed before the screed is laid.
Which kit is best for a retrofit project?
Overlay underfloor heating kits are commonly used for retrofit and renovation projects because they are designed to keep the floor build-up lower than a traditional screeded system.
Can underfloor heating kits be used with tiles, wood or laminate?
Yes, many water underfloor heating systems can be used with tile, wood, laminate or vinyl floor finishes when the correct installation method and floor build-up are followed.
Do I need a screed with every UFH kit?
No. In-screed kits are designed for screeded floors, while overlay panel kits and routed board systems are designed for projects where a traditional screed build-up may not be required.
How do I choose the correct kit size?
Choose the kit size that most closely matches the heated floor area, allowing for fixed units, unheated areas and the final UFH design. Always check the individual product listing for the exact kit contents before ordering.
