Abstract: A kit for constructing a de-aerator for a fluid distribution system includes a gas concentrator adapted to be received in chamber of a T-coupling provided with the kit. A cap is provided that closes a cap connector integrally formed with the T-coupling. The cap supports a valve that opens and closes in response to fluctuations of a level of the fluid in the cavity as air is accumulated in the cavity and discharged by an opening of the valve.

Abstract: A multi-purpose hanger includes a helical support structure for supporting pipe, tubing, conduit or cable against a support surface in any one of a plurality of orientations. The hanger includes an anchor block to which the helical support structure is affixed. The helical support structure spirals 360° between first and second ends to define a gap between the first and second ends that is about equal to an outer diameter of the pipe.

Abstract: A kit for constructing a de-aerator that includes a concentrator is adapted to be connected to a standard pipe coupling. The concentrator is inserted in the path of liquid conveyed through the pipe coupling for aggregating gas, and directing the gas to a cavity. The cavity is encased by the fitting which is a vertical, cylindrical sheath with one end adapted to be inserted into standard pipe couplings, and the other end adapted to be connected with the cap. The cap includes a vent adapted to open and shut in response to lowering and raising of the level of the liquid in the cavity below/above a threshold, respectively.

Abstract: A twist clip for attaching a heat-radiating fin to a conduit of a hydronic heating system includes an upper gripping member, a lower gripping member connected to the upper member by an upright support member, and a handle portion looping downwardly from the lower gripping member to enable a user to hold the clip and to manually twist the clip to cause the upper and lower gripping members to rotate relative to the fin and conduit such that the fin and conduit are clipped together. This twist clip enables quick and easy attachment of fins to conduits, which greatly reduces the time and effort required to install a hydronic heating system.

Abstract: A heat-transferring fin is attached to an electric cable or to a packaged double cable of an electric radiant heating system. The fins can be attached using twist clips. Each twist clip includes an upper gripping member, a lower gripping member connected to the upper member by an upright support member, and a handle portion looping downwardly from the lower gripping member to enable a user to hold the clip and to manually twist the clip to cause the upper and lower gripping members to rotate relative to the fin and cable such that the fin and cable are clipped together. This twist clip enables quick and easy attachment of fins to cables, which greatly reduces the time and effort required to install an electric radiant heating system. This technology can be used in electric radiant floor heating or electric radiant wall heating.
