Where comfort meets control
Welcome to Warm Grid, your destination for reliable underfloor heating products, intelligent heating controls and practical climate solutions.
We believe creating a comfortable, energy-efficient building should not be unnecessarily complicated. Whether you are installing underfloor heating in a home, specifying products for a commercial project or replacing an individual system component, Warm Grid makes it easier to find the products you need.
Our growing product range brings together heating pipe, manifolds, pumps, mixing units, thermostats, floor systems and installation accessories in one convenient place.
From the foundations of a floor system through to the controls that manage room temperature, Warm Grid helps connect every part of the heating system.
Underfloor heating products for every stage of installation
An underfloor heating system relies on a number of components working together correctly. Choosing compatible, well-suited products can make installation easier and help the finished system perform efficiently.
Warm Grid supplies products for each stage of an underfloor heating project, from pipe routing and floor preparation through to water circulation, zoning and temperature control.
Underfloor heating manifolds
The manifold is at the centre of a water-based underfloor heating system. It distributes heated water between individual pipe circuits and allows the flow through each zone to be controlled and balanced.
Our range includes underfloor heating manifolds, manifold extenders, connectors, flow meters, air vents, mounting brackets and other replacement components.
Whether you are installing a new multi-zone system or maintaining an existing setup, our manifold products help create an organised and dependable distribution system.
Pumps and mixing units
Pumps and mixing units help circulate water through an underfloor heating system and manage the temperature entering the pipe circuits.
Warm Grid offers a selection of pumps, single-zone packs, non-mixing sets, four-way mixing units and valve assemblies for different system layouts.
These products can support installations connected to boilers, heat pumps and other compatible heating sources. Selecting the correct arrangement depends on the required flow rate, temperature and system design, which is why accurate product information is an important part of our range.
Underfloor heating pipe
Good-quality pipework is essential for reliable heat distribution.
Our underfloor heating pipe range includes multilayer PE-RT/AL/PE-RT pipe in a variety of diameters and coil lengths. Multilayer pipe provides a practical combination of flexibility, strength and stability for heating distribution systems.
Different pipe sizes are available to suit underfloor heating circuits, primary distribution pipework and wider heating applications.
Pre-insulated pipe
Warm Grid also supplies pre-insulated pipe for heating distribution and supply pipework.
The factory-applied insulation helps reduce heat loss as water travels between the heat source, manifold and heating system. It can also save time during installation by reducing the need to insulate pipework separately on site.
Our pre-insulated multilayer pipe is available in different sizes, coil lengths and colours, making it easier to identify and plan separate flow and return routes.
Heating controls and thermostats
The right controls help users manage comfort while avoiding unnecessary energy use.
Our controls range includes programmable thermostats, smart Wi-Fi thermostats, electric underfloor heating controls, wiring centres, gateway hubs and manifold actuators.
Smart heating controls allow compatible systems to be managed more conveniently, while programmable thermostats can help maintain comfortable temperatures around daily routines.
Wiring centres and actuators connect thermostats to individual manifold zones, allowing each area of a building to call for heat independently.
Together, these products provide the control needed to create a responsive, zoned heating system.
Floor systems for different projects
Not every underfloor heating installation uses the same floor construction.
Warm Grid offers floor system products for low-profile, dry-build and tile-ready installations. These include XPS insulation boards, transition boards, tile backer boards and gypsum fibre boards.
Pre-routed channels help installers position pipework accurately and maintain consistent spacing across the floor. Transition boards can then support changes in pipe direction and help connect the main heated areas of the floor.
Low-profile floor systems can be particularly useful during renovation projects where available floor height is limited.
Underfloor heating accessories and spares
Small installation components can make a big difference to the speed and quality of a project.
Our underfloor heating accessories include:
- Pipe clips and fixing products
- Pipe bend supports
- Slitted conduit
- Backer board washers and screws
- Pipe repair kits
- Cable clips
- Pipe labels
- Manifold tools and connectors
We also stock manifold spares and replacement components for maintenance, system alterations and repairs.
Bringing these products together in one place helps installers reduce delays caused by missing fittings, fixings or specialist components.
Supporting domestic and commercial heating projects
Warm Grid products can support a wide variety of applications, including new-build homes, extensions, renovation projects and commercial heating installations.
Our aim is to make product selection clearer by providing useful specifications, compatible options and straightforward product information.
Customers can browse products by category, compare available sizes and select the components that suit their project.
As the Warm Grid range develops, we will continue to add new heating, control and climate products to support a broader range of installations.
