ProWarm™ Water Underfloor Heating Systems are the perfect choice for homeowners and tradesmen seeking a premium branded water underfloor heating kit. These systems provide unparalleled performance and efficiency, ensuring optimal comfort throughout your home.

ProWarm™ Water Underfloor Heating Single room kits are specifically designed to combine water underfloor heating in one area, such as a living room, with a standard radiator system. Each kit is carefully designed to cover a specific area in square meters when the pipe is spaced at 250mm apart. This spacing provides an output of 115W per square meter, depending on the floor covering. If you require a higher output, we offer high-output kits to meet your specific heating needs.

It's important to note that ProWarm™ Water Underfloor Heating kits feature water temperature control, ensuring precise and efficient heating. Be cautious of systems that lack this essential facility. Additionally, ProWarm™ only uses high-quality European Standard Pert-Al-Pert pipe. The inclusion of an aluminium layer acts as an oxygen barrier, preventing oxygen diffusion through the polymer matrix. This effectively stops corrosion of the metal components within the system, ensuring its longevity and performance.

✅ 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.

The ProWarm™ Water Underfloor Heating Kit is WRAS approved. WRAS approval demonstrates it is of a suitable quality and standard against the Water Supply (Water Fittings) Regulations and Water Supply (Water Fittings) (Scotland) Byelaws, provided it is installed and used in accordance with the installation and requirement notes and any other restrictions within the approval. Any water fitting, which when installed, will carry or receive water from the public mains water supply in the UK, must comply with these regulations. They require that a water fitting should not cause waste, misuse, undue consumption or contamination of the water supply and must be ‘of an appropriate quality and standard’.
