I'm on the hunt for a new water heater. The problem I'm finding is that most that fit my size need use two separate 4500w heating elements totaling 9000w. My current hot water heater is a kenmore 30 gallon that has been using a SINGLE 3500w universal element. The problem I'm face with now is I don't know if my fuse box is set up to handle the dual 4500w elements. I live in a trailer built around the mid 80's (I'd have to look in the closet at the sticker to find out) And I'm pretty sure this is a 100amp breaker box instead of a 200 amp. I did find a water heater online that uses a 1650w single element but it's 28 gallons. And sometimes when I take a hot bath that extra 2 gallons comes in handy. So I think I explained this all pretty clear. Any advice?
