Abstract:
A hydronic heating system having a source of hot supply water and a reservoir of cooler return water, a supply water line from said source, a return water line to said reservoir and one or more heating loops through which water flows from said supply line to said return line, said heating loop including a heating element that is a length of tubing that conducts water from said supply line to said return line and said length of tubing is mounted in a floor, wall or ceiling of a room heated by said system by RFH, RWH or RCH, respectively, of said room, the improvement comprising:(a) a highly thermally conductive radiation plate having an elonaated slot on one side thereof and a corresponding elongated protuberance on the other side thereof, providing a radiating surface on the same side thereof as said elongated slot therein, mounted in said room floor, wall or ceiling, adjacent a surface thereof, with said radiating surface and said slot thereof facing said room,(b) a plate support of relatively low thermal conductivity material providing an elongated space in which said elongated protuberance of said plate fits,(c) said tubing being inserted into said elongated slot and held against said plate in intimate thermal contact therewith,(d) whereby said plate is heated by conduction of heat from said tubing and radiates heat to said room and(e) means providing a direct thermal conduction barrier between said tubing and said floor or wall surface,(f) whereby excessively high floor or wall surface temperature immediately adjacent said tubing are avoided.
