Ceiling Heating kit for Clay Plaster, Lime Plaster or Gypsum Plaster

Retrofitting a naturally healthy room climate

The FLEXIRO water-bearing ceiling heating kit allows the ceiling to be used as a heating surface. It is installed using special honeycomb elements into which a 10 mm PE-RT composite pipe is inserted. This results in a low installation height of 11 mm and, depending on the thickness of the plaster layer, relatively high heating outputs. The low height enables installation in rooms with low ceilings.

Clay, gypsum or lime plasters that are suitable for surface heating are used. The kit includes an RTL valve for connection to conventional heating systems. Special plug-in connections for the heating pipe allow easy installation with few tools. 

Plaster ceiling heating is always the right choice when users are familiar with plastering techniques and high heating outputs are required. The use of natural materials such as clay helps to create a healthy indoor environment by improving humidity control and providing even, dust-free radiant heat. Ceiling cooling is also possible with the system.

Yes, it is possible to use the ceiling heating kit for cooling in summer. Sufficient cool water supply is required though. Further details can be found at: How to use a ceiling heating as cooling ceiling

If there is an unheated room above the planned ceiling heating and the old ceiling has no thermal insulation or the heat transfer coefficient of the ceiling is unknown, we recommend installing an additional layer of insulation. In any case, thermal insulation above the ceiling heating will improve the response time of the heating.

The substructure for the ceiling heating should comply with the dry construction guidelines for suspended ceilings. When using CD profiles and direct hangers, a suspension height of approx. 5 cm can already be sufficient. A small distance to the raw ceiling is also required for the installation of the FLEXIRO connection pipes and plug connections. The dry construction guidelines also permit the use of wooden beams as a substructure for the plasterboard. However, their stability and torsional stiffness is usually less good compared to CD profiles made of metal.
