The Hep2O® system is particularly suitable for domestic hot and cold water supply including potable water, central and underfloor heating.

Hep2O® pipe used in underfloor heating systems is backed by a proven track record of over 25 years experience of the production of flexible pipe for heating and cooling applications.

Advantages of Hep2O® Underfloor Heating System

  • Energy efficient ‘invisible’ warmth – up to 70% savings on running costs compared to radiator systems
  • Uniform heat – good distribution over the whole room
  • Greater level of comfort – the temperature profile is very close to ideal human comfort levels
  • No cold floors – stone and ceramic floors are more pleasant underfoot when warm
  • Complements the operation of condensing boilers – underfloor heating is designed to operate at lower temperatures than radiator systems
  • Ideal for modem lifestyles – allows total freedom on furniture layout and room utilisation
  • Clean interior design – no dusting behind radiators required
  • Safe for children, elderly and the less able – no exposed hot surfaces to create a burn hazard
  • Low allergy – convected airborne dust levels reduced and underfloor heating discourages house dust mite within floor coverings
  • Low maintenance – no decoration or renewal of radiators, and no radiators to ‘drop’ to enable redecoration of rooms
  • No staining of walls – convective air currents above radiators often stain decorations
  • No visible second fix piping – less trade co-ordination problems
  • Less likelihood of insurance leak claims – no risk of leaks from radiators and associated connections
  • Silent running – no expansion creaking or water flow noise via radiators
  • Ideal for high ceilings – maintains the heat at the same level as the occupancy



Ideally the manifold should be located in the centre of the building in order to minimise unequal circuit lengths.


Hep2O Underfloor Heating Pipe is laid into the conductor plates and pipe clips used to fix pipe to insulation.


The flooring material is laid on top of the joists.
