A support structure for a heating or cooling system, comprising: a base; and a plurality of projections extending from said base, said projections being capable of retaining one or more thermal elements positioned adjacent thereto; wherein each of said projections comprises a wall extending from said base, at least part of said wall having an oscillating form. Forming the wall that extends from the base such that it has an oscillating form increases the crush resistance of the support structure. During installation, there are many potential sources of pressure that can crush and/or damage the structure. For example, an installer may stand on the structure while inserting the thermal elements. Additionally, heavy equipment may be placed upon the structure with its load applied through a small area. The crush resistance of the structure comes largely from the walls of the projections. Oscillating wall provides a wall which has an effective thickness greater than its actual thickness and which increases the crush resistance of the structure without a large increase in material.

An uncoupling mat (1) includes a flexible plastic layer (2) made of a film-like plastic with structuring that defines indentations (6) provided with undercuts (5) on the first side (4) and cavities (8) positioned between the indentations (6) on the opposite second side (7). A fleece or fabric (3) is securely connected to the second side (7) and covers the cavities (8). The plastic layer (2) is provided with a plurality of weakening zones (12) which extend continuously between opposing side edges of the plastic layer (2).

A self-assembly hot water mat capable of extending through an assembly, the self-assembly hot water mat capable of being assembled with other self-assembly hot water mats, having four sides, and including a path for circulating hot water includes a plurality of hot water passages formed in the self-assembly hot water mat to provide a plurality of hot water flow paths, an inlet formed at each of the four sides, through which hot water flows in, and an outlet formed at each of the four sides and paired with the inlet, through which hot water flows out.

A floor support includes a base having a bottom surface and a top surface; a plurality of bosses arranged in an ordered array on the base, the ordered array configured to provide multiple options for routing an electric heating cable among the plurality of bosses; and a thermal insulation layer adjacent the bottom surface. Each of the plurality of bosses includes an upper surface; a perimeter wall extending from the upper surface to the top surface, the perimeter wall sloping underneath the upper surface; and an interior wall sloping continuously toward an interior of the boss as the interior wall as the interior wall extends from the upper surface to the top surface.

A membrane for decoupling heated flooring from a subfloor includes a flexible base and a plurality of projections formed into the base and extending outward from the base. Each projection of the plurality of projections has a perimeter wall defining a height of the projection and a top surface integral with the perimeter wait for supporting a flooring adhesive and/or for bearing a load when the heated flooring is installed. The projections have one flange portion extending from the perimeter wall and effective for retaining a heater cable within a channel formed between each pair of adjacent projections Each channel may have exactly one flange portion extending over it and forming an overhang for retaining heater cables of different diameters. The corresponding flange portions of adjacent projections do not face in the same direction or the opposite direction, providing for a minimum number of flange portions to be used.

A heat exchanger element (1) has a heat-conducting body (2) and a heat-transfer fluid pipe (8) which is connected thereto in a heat-conducting manner and which are embedded in sections in ducts (5) of heat-conducting material in heat-conducting contact, the ducts (5) having a channel-shaped locating section (7) and two tabs (6) connected thereto, so that the ducts (5) are approximately -shaped in cross-section, and wherein the tabs (6) are connected flat to the heat-conducting body (2) in order to establish the heat-conducting connection of the heat-conducting fluid pipe (8) to the heat-conducting body (2). To produce the heat exchanger element (1), foil strips are pressed into grooves so that they each form a section (7) pressed into the grooves (23) in a channel-like manner and laterally projecting tabs (6); sections of a heat transfer fluid pipe (8) are inserted into the channel-like sections (7) of the foil strips; and the tabs (6) are connected flat to a heat transfer body (2). A building panel with an area of at least 1 m.sup.2 comprises a heat exchanger element (1) with a heat exchange surface (14), a cooling device and a collecting device, the cooling device being designed to cool the heat exchange surface (14) in contact with the ambient air to a temperature below the dew point of the water vapour in the ambient air, the contact surface having an inclination to the horizontal so that condensed water can drain from it, and the collecting device being designed to collect and discharge condensed water in a controlled manner. A method of dehumidifying air uses a building panel which lowers the temperature of the ambient air below the dew point so that the air moisture condenses on the building panel, the building panel being so inclined that the condensed water drains into a collecting device.
