Abstract

A shaped mounting module for a liquid-type panel heating system is provided on which a heater pipe is mounted by means of discrete holder devices. In one embodiment, the panel is provided with a grid of flanges for supporting the heater pipe above the surface of the panel. In another embodiment, the panel is provided with a plurality of protrusions having their upper surfaces approximately level with the top of the mounted heater pipe to form a plurality of intersecting channels through which the heater pipe passes. Each of the holder devices has a plurality of opposite paired axially symmetrical openings formed by a plurality of axial symmetrical fingers having recesses therebetween. The heater pipe is either pressed into or passed through a selected pair of openings during assembly of the heating system. The holder devices are affixed to the panel either during the panel forming process or by adhesive bonding of the base into circular depressions on the panel during assembly of the heating system.
