A thermal wall system may include a plurality of blocks configured to interconnect with each other forming a monolithic wall. The plurality of blocks form a series of vertical interior cavities that each extend from a top of the plurality of blocks to a bottom of the plurality of blocks, and tubing vertically extends through the series of vertical interior cavities.

A hydronic panel and system for heating and/or cooling a room is disclosed. The hydronic panel includes a plurality of contiguous channels. A first chamber is located at a first end, preferably the upper end, of the panel and includes an inlet and communicates with a first subset of the channels. A second chamber is located at an opposite end of the panel and communicates with the first subset and also with a second subset of the channels. A third chamber is located at the first end of the panel, the third chamber communicates with the second subset of the channels and includes an outlet. In this configuration, heated or cooled water flows from the inlet into the first chamber, through the first subset of the channels, to the second chamber, through the second subset of the channels, into the third chamber and out the outlet. Consequently, the heated or cooled water can heat or cool the space. In addition to at least one hydronic panel, the system includes a source of heated and/or cooled water under sufficient pressure to cause the water to flow through the panel. The system also includes a controller to control one or both of the temperature of the water and the flow rate of the water through the panel.

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.

The present invention relates to a slidable mounting block for insertion into a rail having a partially closed profile, the mounting block having a front face and a rear face opposite to the front face, the front face facing an open part of the partially closed profile when inserted into the rail. The mounting block comprises a first hole accessible from the front face in a first fixing area of the mounting block and configured for screwing in a threaded part of a first fastener, a recess accessible from the rear face in a second fixing area of the mounting block and configured for holding a head of a second fastener, and a second hole accessible from the front face in the second fixing area, the second hole being co-aligned with the recess and configured for passing a shaft of the second fastener through the mounting block.

Building heating and/or cooling methods are provided that can include: distributing fluid from within conduits within a concrete floor of a building to conduits within grounds surrounding and/or supporting the building; diverting at least some of the fluid exiting the conduits within the grounds surrounding and/or supporting the building to a dehumidifier operably associated with the interior of the building; and returning the at least some of the fluid from the dehumidifier to the conduits within the grounds surrounding and/or supporting the building.

A support for the heating elements of radiant coverings and floors is disclosed. One example of a support disclosed herein includes bosses having a concave portion. In some examples, defined on the surface of the concave portion is at least one adhering low relief, for example four adhering low reliefs may be provided per concave portion.

The present invention provides a flexible mat with fluid conduit, methods of manufacture thereof and apparatus for the manufacture thereof. In an embodiment, the mat comprises a base layer, one or more fluid conduits and a thermoplastic bonding tape that attaches the fluid conduits to the base layer. The base layer can be a textile fabric, mesh or netting, or a flat flexible sheet. The base layer is preferably also formed of a thermoplastic layer. The fluid conduits can carry heated or cooled fluid, such as water, that can be used for heating or cooling an environment in which the device is deployed. For example, the device can be used for heating or cooling in a greenhouse environment. The fluid conduits can additionally or alternatively carry irrigation fluids, such as water or treated water, for irrigating plants and crops. The fluid conduits can additionally or alternatively carry gases, such as carbon dioxide (CO.sub.2) or carbon dioxide mixed with other gasses, for treating plants and crops.

A thermal transfer panel is provided, wherein the thermal transfer panel is vacuum formed from separate precursor sheets to form an integral thermal transfer panel. The integral thermal transfer panel defines both fluid flow channels and an interconnecting web, wherein the interconnecting web defines a structure or fastening beam for accommodating fasteners than can retain the thermal transfer panel relative to a building structure, such as a joist. The thermal transfer panel includes surface indicia to allow an installer to determine the location of at least one of the fluid flow channel and the interconnecting web in the thermal transfer panel. Traditional flooring can be fastened to the thermal transfer panel without damaging the integrity of the fluid flow channel.

A membrane system includes a base membrane and a cover membrane. The base membrane is configured to be installed between a subfloor and floor tiles to allow movement of the floor tiles relative to the subfloor. The base membrane includes a base layer and studs projecting from the base layer. The studs are configured to hold a heating cable in place when the heating cable is positioned between adjacent ones of the studs. The studs have free ends that define pockets therein. The cover membrane is configured to be coupled to the base membrane to encapsulate the heating cable between the base membrane and the cover membrane. The cover membrane includes a cover layer and studs projecting from the cover layer. The studs on the cover membrane are configured to fit within the pockets in the base membrane to couple the cover membrane to the base membrane.
