Just got a used 8 yo 50 gallon Rheem water heater and want to put it in my house ( double wide m/h ) to replace the existing 19 yo Rheem 40 gallon wh. The old one is a single heating element 3500 watt unit, the newer unit is a double element 4500 watt unit, both 220v.
My question is; does the extra 1000 watts mean I'll have to upgrade the wiring/breaker?, there is no amperage given on the labels. I could do this my self but need to know if I should be concerned about the existing wiring.
Many thanks, Carroll
