Sonoff won't handle the amperage required by a water heater.  You could place a 2 pole HVAC contactor  rated for continuous duty with contacts rated equal to or greater than your heater's circuit breaker current in a proper enclosure and use Sonoff to control the coil.   A possible circuit is below.  As always, consult a qualified electrician and use at your own risk.
