Abstract

Abstract The present invention provides, as one embodiment thereof, a hot water heat panel which includes a wooden board; a wooden frame fixed onto the wooden board; a grid-like support unit having a number of compartments standing normal to the surface of the wooden board within the wooden frame; a plurality of parallel grooves extending from one of the side edges of the wooden frame to another opposing thereto, so as to pass through the surface of the support unit and the surface of the wooden frame continuous therewith, the grooves being suitable for receiving a hot water pipe; an undulated metallic plate fixed to the wooden frame so as to continuously cover the surface of the wooden frame, the surfaces of the grooves and the surface of the gridlike support unit. Further, the invention provides, as another embodiment thereof, a hot water heat panel which includes a wooden board; a wooden frame fixed onto the wooden board; a plurality of supports extending from one of the side edges of the wooden frame to another opposing thereto to form spaces between the supports and the frame; a plurality of parallel grooves extending from one of the side edges of the wooden frame from a point other than that from which the supports extend, to another opposing thereto, in spaced apart relationships with one another, the grooves being suitable for receiving a hot water pipe; and an undulated metallic plate fixed to the wooden frame so as to continuously cover the surface of the wooden frame, the surfaces of the supports and the grooves.
