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 a space defined at least in part by said plate, in which the length of tubing is held and a compliant filler material fills the space between the tubing and the plate, so that the tubing is held in the space 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.
