ProWarm™ Water Underfloor Heating Systems are the perfect choice for both homeowners and tradespeople seeking a Premium Branded water underfloor heating kit.

Our High Output - Water Underfloor Heating Single room kits are specifically designed for areas with high heat loss, such as conservatories, where you wish to combine the underfloor heating with a standard radiator system. Each kit is tailored to cover a specific area in square meters when the pipe is spaced at 200mm apart, providing an output of 125w per square meter. If you require a lower output, we also offer standard output kits for your convenience.

Please Note: ProWarm™ Water Underfloor Heating kits are equipped with advanced water temperature control, a feature to be cautious of when considering other systems. Our commitment to quality is evident in our choice to use only high-quality European Standard Pex-Al-HDPE pipe. The inclusion of an aluminium layer acts as an oxygen barrier, effectively preventing oxygen diffusion through the polymer matrix, and thereby eliminating corrosion risks for the metal components in the system.
