ProWarm™ Water Underfloor Heating Systems offer the perfect solution for homeowners and tradesmen looking to install a premium branded water underfloor heating kit. These systems are designed to provide efficient and effective heating throughout your home, ensuring optimal comfort in every room.

Our multi-room water underfloor heating kit includes all the necessary pipe and fittings to cover your chosen zone size. With this comprehensive kit, you can easily and seamlessly install the underfloor heating system in multiple rooms, creating a consistent and cozy environment throughout your home.

It's important to note that ProWarm™ Water Underfloor Heating kits feature water temperature control, which is a crucial feature to consider when selecting a system. Be cautious of systems that lack this facility, as temperature control plays a key role in ensuring optimal comfort and energy efficiency. Additionally, ProWarm™ only utilizes high-quality European Standard Pex-Al-HDPE pipe in our kits. The inclusion of an aluminium layer in the pipe acts as an effective oxygen barrier, preventing oxygen diffusion through the polymer matrix. This barrier significantly reduces the risk of corrosion in the metal components of the system, ensuring its durability and longevity.

✅ The ProWarm™ Water Underfloor Heating Kit is WRAS approved, this indicates the product has been thoroughly tested to demonstrate it is of suitable quality and standard against the requirements of the Water Fittings Regulations and Scottish Byelaws.

ProWarm™ Water Underfloor Heating Kit Components

Below, we provide examples of the components that could be included in your ProWarm™ Water Underfloor Heating Kit. For precise information on the manifold size and pipe length suitable for your chosen kit size, please refer to our convenient kit content comparison table.

Grundfos Mixing Unit: A rated UPM3 Grundfos Manifold Pump/Mixing Valve Unit, which ensures efficient mixing and distribution of the heated water within the system. It plays a crucial role in maintaining the desired temperature and providing even heat distribution.
Manual Thermostat: For a small additional fee, you have the option to upgrade your thermostat to a digital, programmable, wireless, or touchscreen one. This allows you to have precise control over your underfloor heating system, adjusting the temperature according to your preferences and schedule.
Manifold: A stainless steel manifold with an adjustable flow meter. The manifold is factory assembled on a fixing bracket, simplifying the installation process and providing convenient control over the water flow.
Wiring Center and Actuators: Please note that the image of the wiring center is generic and may vary depending on the thermostats purchased. The wiring center and actuators are essential components for controlling and regulating the operation of the underfloor heating system.
ProWarm™ European Standard Pex-Al-HDPE Pipe: Our kits include high-quality 16mm (outside) diameter Pex-Al-HDPE pipe, adhering to the European standards of quality and performance. This pipe is specifically designed for water underfloor heating systems and ensures efficient heat transfer throughout the system.
ProCrate Egg Crate: The ProCrate Egg Crate system provides a quick and simple installation process, featuring ready-made pipe spacing and pipe retaining fixings. It streamlines the setup of your underfloor heating system, making it more convenient and efficient.
Edging Insulation: Edge Insulation is used around the edge of the room to minimize unwanted heat loss and allow for expansion. It plays a crucial role in maximizing the overall performance and efficiency of the underfloor heating system.
Tools: Our kits include essential tools such as a Pipe Re Rounding Tool, Pipe Staples, Pipe Cutters, Nuts and Olives, and Valves. These tools are necessary for a smooth and successful installation process.
