Patent number: 10072852Abstract: A mat includes a base and a plurality of studs that together may position an electric radiant heating element within a floor or wall, and may protect the electric radiant heating element as the floor or wall are constructed. The base extends in at least two directions that define a plane. Two or more of the plurality of studs has a cylindrical body that includes a surface and a top, the surface extends from a respective portion of the base in a third direction that does not lie within the plane and that is at an angle between and including 84 and 96 degrees relative to the respective base portion, and the top includes a hole to allow air to pass from outside the stud to an interior region. By using the mat one can quickly install a plurality of positioning devices to hold the electric radiant heating element at desired locations in the floor while the floor is constructed.Type: GrantFiled: March 25, 2015Date of Patent: September 11, 2018Inventor: Michael Fuhrman

Patent number: 10072853Abstract: A water heater is provided having an insulated tank having a water inlet and a water outlet, and further defining an interior volume to contain a quantity of water. A primary heating arrangement applies heat energy to the water so as to heat the water. In addition, the primary heating arrangement is configured to maintain the water during standby periods between upper and lower set point temperatures. A supplemental heating arrangement is operative to supply additional heat energy to the water in order to lessen energy usage by the primary heating arrangement during the standby periods. In accordance with a preferred embodiment, the supplemental heating arrangement includes at least one photovoltaic panel and a supplemental heating element. Control electronics are operatively interposed between the at least one photovoltaic panel and the supplemental heating element.Type: GrantFiled: January 4, 2016Date of Patent: September 11, 2018Assignee: RHEEM MANUFACTURING COMPANYInventors: Raheel A.
