Abstract
Abstract A hydronic heating system that has a boiler supplying hot supply water, a reservoir of cooler return water, a supply water line, a return water line and one or more heating loops through which water flows from the supply line to the return line, the heating loop including a heating element that is a length of tubing that conducts water from the supply to the return and is mounted in a wall or a floor of an area heated by said system by RFH or RWH has: a thermally conductive plate mounted in the area floor or wall, adjacent a surface thereof and means for holding the length of tubing in intimate thermal contact with the plate, so that the plate is heated by conduction of heat from the tubing and the plate has a radiating surface that radiates heat to the area. The plate with slot is provided as a modular piece and several such modular pieces are arranges in line attached to the sub-flooring for RFH, or the wall studs for RWH, for insertion of the length of tubing in the aligned slots thereof; and following such insertion, the installation is ready for a finishing floor or wall covering. Thus, RFH or RWH is installed "dry" (without wet concrete, cement or plasted) and can be accessed later by removing the finishing cover.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
193 words
In 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 wall or a floor of an area heated by said system by RFH or RWH, respectively, in said area, the improvement comprising: (a) a relatively highly thermally conductive plate having a radiating surface mounted in said area floor or wall, adjacent a surface thereof, (b) means attached to said plate providing an elongated space for holding said length of tubing adjacent said plate and (c) a compliant filler of relatively high thermal conductivity material that fills around said tubing between said tubing and said plate, (d) whereby said plate is heated by conduction of heat from said tubing and (e) said plate radiating surface radiates heat to said area.
Claim 2
Dependent Claim
193 words
In 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 wall or a floor of an area heated by said system by RFH or RWH, respectively, in said area, the improvement comprising: (a) a relatively highly thermally conductive plate having a radiating surface mounted in said area floor or wall, adjacent a surface thereof, (b) means attached to said plate providing an elongated space for holding said length of tubing adjacent said plate and (c) a compliant filler of relatively high thermal conductivity material that fills around said tubing between said tubing and said plate, (d) whereby said plate is heated by conduction of heat from said tubing and (e) said plate radiating surface radiates heat to said area.
Claim 3
Dependent Claim
