A radiant heating installation system is provided herein. The system includes a radiant heating tubing defining a tubing run. The system can include a first removable positioning fixture that receives a portion of the radiant heating tubing and temporarily restrains the radiant heating tubing in a deflected configuration. The system can also include a second removable positioning fixture configured to that receives a second portion of the radiant heating tubing and temporarily restrains the radiant heating tubing along a run of the radiant heating tubing.

A radiant panel having a channel or groove is manufactured using, for example, a simple U shaped channel with substantially parallel vertical sides is one embodiment. Because varied diameter tubing pressed into curved channels of varying radius will change their shape from round to oval by different amounts, channel width will be reduced at curved channel areas as appropriate, in light of tubing size and channel radius. This reduction in curved channel width compared to straight channel width will allow for a consistent friction force to be developed upon pressing the tubing into a channel, for retention purposes, regardless of whether the channel is straight or curved. In other embodiments the depth of groove may be varied as well to allow for the increased vertical dimension of tubing which is deformed from round to oval by bending forces. By varying the depth as necessary, tubing can be installed consistently flush with the surface of the radiant panel which enhances the installation of covering materials whether they may be finish floor materials or wall or ceiling finishes. Varying width and depth will also tend to maximize the contact area of tube to conductive surface, thereby improving the flow of heat from tube to radiant panel.

A universal membrane is configured to be installed between a subfloor and floor tiles to allow movement of the floor tiles relative to the subfloor. The universal membrane includes a base layer, a plurality of studs projecting from the base layer, and a plurality of sidewalls projecting from the base layer and disposed between adjacent ones of the plurality of studs. Each sidewall of the plurality of sidewalls forming a perimeter of a pocket. The base layer forms a bottom wall of the pocket.

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.

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 planting system having a plurality of potting trays that can be interconnected in a modular fashion to create a multitude of different configurations. Each potting tray has a plurality of holes operatively connected with a conduit through which plumbing can be incorporated into the planting system to water plants in the potting trays via the plurality of holes. A plurality of pedestals may be used to elevate the planting system. Lateral braces may be used to interconnect the plurality of pedestals.

Provided is a self-assembly hot water mat capable of extending through assembly. A 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 hydronic floor heating system as it relates to an HVAC apparatus, approach and system. Aspects of the present system and approach may include a radiant floor optimization mode, low floor temperature in vacation mode, modifying a 300 Hz, or so, reading principle base on implementation of Pseudo-random jittering of a reading event improving short-term accuracy of the individual readings, and a combination of hardware and software filters for using thermal sensors with extended cable length.

A support structure for a heating or cooling system includes a plurality of projections designed to be capable of retaining one or more thermal elements positioned adjacent thereto. The projections are positioned so as to form a first set of substantially parallel undulating channels, each channel having one of the projections forming at least a part of the inner radius of each undulation, with each projection having a recess formed in a side wall thereof facing said channel. The undulations of the channel ensure that a thermal element positioned in the channel will make contact with the projections each time it has to bend around one, without requiring spacing of the projections to squeeze the thermal element. The thermal element can thus be held securely without any play (unwanted lateral movement) in a channel that is slightly wider than the thermal element. Recesses in the channels at the contact points also restrict movement in the vertical direction, thus preventing the thermal element from popping out of the channel, while not requiring any restriction narrower than the thermal element.
