Modules for underfloor heating and/or cooling systems and system comprising such modules

摘要

A heating and/or cooling module (1) for use in an underfloor heating and/or cooling system and system comprising such modules. Each module comprises a continuous length of plastics tubing (2) laid in a serpen_- tine configuration on a thermally conductive support (3) for the passage of water through the tubing. The tubing (2) and support (3) are prefabricated as a portable unit which, because the support is flexible, can be folded about an axis parallel to the length of the tubing. The tubing (2) has an internal bore which is sufficiently small to prevent air from becoming trapped in the tubing. The tubing (2) and support (3) may be encapsulated in a flexible envelope to accomodate expansion and contraction movements (figure 1).
