Abstract:
1. A modular tankless water heater system comprising: a power module coupled to a power source; a water heater module including a casing having a first end, a second end, and a plurality of conduits formed therein, extending from the first end to the second end, a top head manifold coupled to the first end of the casing and including a port aligned with each of the plurality of conduits, a bottom head manifold coupled to the second end of the casing including a port aligned with each of the plurality of conduits, an immersion heating element extending through each port of the top head manifold and into the conduit aligned therewith, each immersion heating element coupled to the top head manifold, and a flow path from through the plurality of conduits, the plurality of conduits coupled in fluid communication by channels between ports of the top head manifold and between ports of the bottom head manifold a relay switch coupled to each immersion heating element and to the power module; and a control unit receiving fluid flow data and fluid temperature data from the water heater module, coupled to the relay switches for actuating the relay switches upon selected fluid flow and fluid temperature data.
