Our water underfloor heating systems are suitable for both homeowners and tradesmen wishing to install a premium quality water underfloor heating kit.

The water underfloor multi-room water underfloor heating kit will supply all the pipe and fittings you'll need to cover your chosen zone size.

Key features:

  • Water underfloor heating kits feature water temperature control
  • The aluminium layer within the pipe acts as an oxygen barrier, preventing the oxygen diffusion through the polymer matrix, which stops corrosion of the metal components in the system
  • European standard Pex-Al-HDPE pipe
