    Not normally, no.
    An electric water heater is a 240v circuit. There is no neutral in this circuit, which you need to get your 120v.
    Also, a water heater is a 30A, 240v, circuit. You CANNOT power general use receptacles and/or lighting off a 30A circuit.

    Sounds like you have a basement or crawl space-"under my home". Better off to pull a wire from a lightly used wall outlet into the basement/crawl and go from there. In a crawl space you need to use UF cable, not NMC.
