The ProWarm™ Water Underfloor Heating Multi Room Systems are the ideal choice for homeowners and tradesmen looking to install a premium branded water underfloor heating kit. These systems provide efficient and comfortable heating for your entire home, ensuring a cozy and inviting atmosphere.

This multi-room water underfloor heating kit includes all the necessary pipe and fittings to cover your chosen zone size, allowing you to create a customized heating solution tailored to your specific needs. Whether you have a small or large space to heat, this comprehensive kit ensures a hassle-free installation process.

Note: ProWarm™ Water Underfloor Heating kits feature water temperature control, which is an essential feature to consider. Be cautious of systems without this facility. ProWarm™ only uses high-quality European Standard Pex-Al-HDPE pipe. The aluminium layer acts as an oxygen barrier, preventing oxygen diffusion through the polymer matrix and protecting the metal components in the system from corrosion.

✅ 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 are examples of all the products that could be included in your ProWarm™ Water Underfloor Heating Kit. To find the exact manifold size and pipe length for your chosen kit, please refer to our handy kit content comparison table below.

Grundfos Mixing Unit

An A-rated UPM3 Grundfos Manifold Pump/Mixing Valve Unit is included in the kit. This unit ensures efficient circulation and temperature control of the water in the underfloor heating system.

Manual Thermostat

By default, the kit includes a manual thermostat. However, for a small additional fee, you can upgrade to a digital, programmable, wireless, or touchscreen thermostat, providing enhanced control and convenience.

Manifold

The kit includes a stainless steel manifold with an adjustable flow meter. The manifold is factory assembled on a fixing bracket, making installation easier and more efficient.

Wiring Center and Actuators

The kit includes a wiring center and actuators. Please note that the wiring center image is generic and may change depending on the thermostats purchased.

ProWarm™ European Standard Pert-Al-Pert Pipe

The kit includes 16mm (outside diameter) ProWarm™ European Standard Pert-Al-Pert pipe. This high-quality pipe ensures optimal heat distribution and durability.

Edging Insulation

Edge insulation is included in the kit and should be used around the edge of the room to minimize unwanted heat loss and allow for expansion.

Tools

The kit includes essential tools such as a pipe re-rounding tool, pipe staples, pipe cutters, nuts and olives, valves, and all other items required for a successful installation.
