This HPWH made by Rheem requires only a 120VAC wall outlet. It requires a plastic condensate drain tube. It uses about 350 to 450 Watts. Theirs drew 65 kWh for the month of August. Their electric resistance water heater used 290 kWh average per month. The water heater cost $2533.00 from Home Depot. This article
