We're looking at a 120 volt, 3600 watt, 30 amp insta-hot water heater for a shower. The 30 amp branch circuit is ~200' and the contractor used #10 conductors. As you may guess the water is not hot making this an insta-luke warm water heater. Would it be possible to use a buck/boost transformer at the shower end to get the voltage up to 120 volts? My quick calculation shows a voltage of ~108 volts at the HWH. If so how would you size the buck/boost trans?
