A panel comprising a heat providing layer is presented. The panel includes panel coupling means arranged for coupling the panel to adjacent panels. End panel grooves, at least partly extending between first and second opposite longitudinal sides of the panel, are arranged in the end panel coupling means of the panel. In order to provide heat, electrical end connectors are arranged in the end panel grooves of the panel. The electrical end connectors are arranged for being electrically connected to the heat providing layer of the panel, at least partly including an electrically conductive material, and at least partly protruding from the one or more end panel grooves, thereby providing an electrical connection between the heat providing layer of the panel and a corresponding heat providing layer of at least one adjacent panel coupled to the panel.

A deck assembly is formed of a plurality of deck boards spanning across a second of joist members to provide structural support between the joist members. Each deck board includes a base frame with an upper panel having an upper supporting surface and a plurality of support legs extending downwardly from the upper panel in engagement with the joist members to support the upper panel spaced above the joist members. Each deck board also has one or more channels formed in the upper panel so as to define an elongate passage which is recessed downwardly relative to the upper panel and which is open at a top side at the upper supporting surface of the upper panel to receive an elongated flexible heating member within the channels of the deck boards. Panels of finishing material on the upper supporting surfaces span over the heating member.

A circulation pump assembly for a heating and/or cooling system includes an electric drive motor (108) and a connected pump housing (106) in which at least one impeller (118) is situated and which comprises a first inlet (112) and a first outlet (114). The pump housing (106) includes a second inlet (122) which is connected in an inside of the pump housing (106) at a mixing point (130) to the first inlet (112). A regulating valve (134), which is designed for regulating the mixing ratio of two flows mixing at the mixing point (130), as well as a control device, which controls the regulating valve (134) for regulating the mixing ration, are arranged in the pump housing (106). A hydraulic manifold is provided with such a circulation pump assembly.

Heat buffer comprising at least mechanically coupled wall parts, wherein each of the wall parts comprises a substantially plate-like body; a liquid throughflow circuit incorporated in the body; one or more hydraulic couplings accessible from the outer side of the wall part for discharge and supply of liquid to the liquid throughflow circuit and configured for coupling to hydraulic couplings of a similar device; and is coupled at a mutual angle about a substantially vertical axis to a similar wall part, wherein the mechanically coupled devices are connected such that they enclose one space and wherein the heat buffer also comprises a floor and/or cover part for closing the enclosed space on an upper and/or underside.
