ABSTRACT:
The apparatus of the present invention comprises a hydronic distribution system using prefabricated, flexible cable containing plastic tubing to provide liquid supply and return conduits for the hydronic system. The plastic conduits are enclosed in a foam thermal insulation material which is encased in a flexible, moisture impervious shell. In an alternate embodiment of the invention, the flexible cable includes electrical conductors for supplying power to a fan and for carrying an electrical control signal from a thermostat. The flexible cable thus described can be installed in a building easily and quickly in a manner similar to that currently used for electrical cable.
