A hydraulic manifold for a hydraulic heating and/or cooling system includes a feed conduit (212) and a return conduit (216). The feed conduit (212) includes at least one feed connection (258), and the return conduit (216) includes at least one return connection (260), for the connection of a load circuit (228). A load module (204), in which a section of the feed conduit (212) with the feed connection (258), and a section of the return conduit (216) with the return section (260) are formed, includes at least one mixing device with a pump (232) and with a regulating valve (230), to admix fluid from the return connection (260) to a fluid flow from the feed conduit (212) to the feed connection (258). The section of the feed conduit (212) and the return conduit (216) in each case include an additional contact for connection with a further load module.

An uncoupling mat includes a flexible layer made of a film-like plastic with structuring that defines indentations provided with undercuts on a first, top side and a series of annular cavities formed on an opposite second, bottom side. The annular cavities on the bottom side each define a recess on the first side. The indentations have a cross-section adapted to receive a heating cable therein such that the cable can be held in position by the indentations. A plurality of weakening zones each extends between two rows of annular cavities in a straight line to allow the plastic layer to move substantially transversely to the direction of extension of the weakening zones.

A flooring underlayment comprises a membrane that includes a body panel having a panel top surface and a panel underside surface spaced apart from the panel top surface by a panel thickness. The membrane further includes a plurality of dimples projecting downward from the panel underside surface, each dimple having a dimple upper end open to the panel top surface, a closed dimple lower end spaced apart from the dimple upper end by a dimple height, and a dimple sidewall extending between the dimple upper end and the dimple lower end, the dimple sidewall configured to inhibit collapse of the dimple height when a load is applied to the flooring underlayment during use. The membrane includes a plurality of grooves open to the panel top surface and formed within a groove body projecting downward from the panel underside surface, each groove shaped to receive an elongated heating element therein.

An uncoupling mat includes a flexible plastic layer (2) made of plastic film with structuring that defines indentations (6) provided with undercuts (5) on a first, top side (4) and cavities (8) positioned between the indentations (6) on an opposite second, bottom side (7). A fleece or fabric (3) is securely connected to the bottom side (7) and covers the cavities (8). A cross-section of the indentations (6) in at least some corner regions (10) increases from the bottom side (7) toward the top side (4).

An uncoupling mat includes a flexible plastic layer having indentations provided with undercuts on a first, top side and cavities positioned between the indentations on an opposite bottom side. A fleece or fabric is securely connected to the second side and covering the cavities. A plurality of weakening zones is formed in the top surface of the film-like plastic, which each extend between two rows of indentations in a straight line between opposing side edges of the plastic layer and allow the plastic layer to move substantially transversely to the direction of extension of the weakening zones. Some of a first group of weakening zones extend parallel to one another across the top surface of the film-like plastic. Some of a second group of weakening zones extend parallel to one another across the top surface of the film-like plastic and intersecting the first group of parallel weakening zones.

A hydraulic manifold for hydraulic heating and/or cooling systems includes a feed conduit and a return conduit. The feed conduit includes at least one feed connection and the return conduit includes at least one return connection, for the connection of a load circuit. The manifold has a modular construction with a main module and connected load module(s). The main module includes a section of the feed conduit and/or of the return conduit as well as an electric connection. The load module includes a section of the feed conduit with a feed connection, and/or a section of the return conduit with a return connection, as well as at least one regulating device for regulating the flow through a load circuit connected to the feed connection and to the return connection. The main module includes a manifold control device for the control of the regulating device in the load module(s).

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.
