Clay Heating Panels – Thermal Heating System

  • Designed to carry hot or cool water through walls or ceilings.
  • Not suitable for areas where there is contact with running water.


Clayworks Clay Heating Panels are clay and wood fibre dry-lining boards with integrated heating pipes, designed to carry hot or cool water through walls or ceilings. The panels thereby act as the heating or cooling element within a building.

The panels have a sandwich construction. The integrated heating pipes are identical to those used in underfloor heating and require no specialist plumbing.

Once installed, the system sits within the walls or ceilings. The application of a thin layer of fresh clay plaster completes the installation, creating a seamless and healthy finish. Once linked to a heat source, the panels warm up gently to radiate heat either downwards or across the room. The individual heating loops are linked to thermostats which allow the end user to control the temperature as they would do with conventional heating systems.

Features and benefits:

  • Due to the breathability of both wood fibre and clay, the panels help minimize damp, aid thermal comfort and help protect the structural integrity of the building.
  • No volatile organic compounds (VOCs), toxins and no off-gassing.
  • Clay can help to keep room humidity at between 40% and 70%, the level at which the majority of adverse health effects are kept at bay including asthma. At these levels the likelihood for airborne infectious bacteria and virus to survive is the lowest.
  • The panels are also suitable for use as a cooling system: if cold water is sent through the water pipes, the system functions as gentle air conditioning without the noise, drafts and high maintenance associated with traditional air conditioning systems.
  • In warmer climates, running cold water through the pipes offers a gentle and healthy alternative to mechanical air conditioning.
  • The panels are particularly valuable for historic building refurbishments due to their permeability. Clay plaster allows walls within buildings to breathe. The system also offers an alternative to underfloor heating where historic floors need to be preserved and areas of walls or ceilings are more suitable for integrated heating.
  • Removes the need for radiators.
  • Targeted heating.
  • Energy saving.
  • Absorbs and stores indoor air pollution (odours and smells).
  • High inherent stability – good for stud constructions.
  • High level of sound insulation. Sound can be reduced by high mass material or soft wave reducing material.
  • Can be fixed on ceilings or to the underside of rafters or on walls.
  • The system includes end panels and connecting panels.
