  • Patent number: 7206506
    Abstract: A fluid heating system includes a fluid supply conduit, a hot fluid conduit, and a fluid heating tube assembly. The fluid heating tube assembly includes an inlet coupling coupled to the fluid supply conduit, an outlet coupling coupled to the hot fluid conduit, and at least one fluid heating tube coupled between the inlet coupling and the outlet coupling. The at least one fluid heating tube includes a tube formed of heat conducting material, a dielectric coating permanently bonded on an outer surface of the tube, and a resistive layer permanently bonded on the dielectric coating. A power distributor is coupled to the fluid heating tube assembly and coupleable to a power source. A switch is coupled between the power distributor and the fluid heating tube assembly to control current flow from the power distributor to the at least one fluid heating tube.

  • Patent number: 7164851
    Abstract: Control circuitry is disclosed for use with a tankless water heater system including a plurality of water conduits connected in series. The control circuitry includes a plurality of water heater elements, one each associated with each of the plurality of water conduits. A controller includes a central processing unit (CPU) with an operating program and each of the plurality of water heater elements are coupled to the CPU. The CPU is programmed to individually activate one of the water heater elements to a predetermined power level in response to a demand for heated water. The number of water heater elements activated and the power level of the activation is determined by the demand for heated water.

  • Patent number: 7088915
    Abstract: A tankless water heater module is disclosed and includes a casing having a first end, a second end and a plurality of conduits formed therein. A top head manifold is coupled to the first end of the casing and includes a port aligned with each of the plurality of conduits. A bottom head manifold is coupled to the second end of the casing and includes a port aligned with each of the plurality of conduits. An immersion heating element extends through each port of the top head manifold and into the conduit aligned therewith. A flow path extends through the plurality of conduits, the plurality of conduits coupled in fluid communication by channels between ports of the top head manifold and a channel between ports of the bottom head manifold.
