Modular underfloor heating system, uses pipework fed through multiple channels in prefabricated concrete floor blocks

摘要

Each module (1) of concrete flooring has slightly chamfered edges to allow for grouting. Through the length of each module are a large number of identical channels (2). Flexible pipes with a circular cross section are fed through each channel. The pipes are connected in series by additional pipes in transverse grooves in the blocks. The gaps between the flexible pipes and the walls of the channels can be filled with a heat-conducting filler.
