ProWarm™ Water Underfloor Heating Systems are the ideal choice for homeowners and tradesmen wishing to install a Premium Branded water underfloor heating kit.

ProWarm™ High Output - Water Underfloor Heating Single room kits are ideal for combining one area of water underfloor heating in a high heat loss area (eg. conservatory) with a standard radiator system. Each kit is designed to cover an area in square meters when the pipe is spaced at 200mm apart. This spacing provides an output of 125w per square meter. If you require a lower output please choose a standard output kit.

Please Note : ProWarm™ Water Underfloor Heating kits feature water temperature control, beware of systems without this facility. ProWarm™ only use high quality European Standard Pex-Al-HDPE pipe. The aluminium layer acts as an oxygen barrier, preventing the oxygen diffusion through the polymer matrix, which stops corrosion of the metal components in the system. Visit prowarm.com for more details.
