Hello, I recently leased a new shop and inside is a giant electric water heater, about 50-60 gallons I think. The only reason it is there is for hand washing in the bathroom, obviously I don't need one that large for that purpose.
I'm wondering, can anyone tell me roughly how my kwh a water heater of that size uses when it's just sitting there staying hot? I know it could vary quite a bit but I'm just looking for an estimate - I'm thinking about replacing it with a much smaller one. It's a 1994 vintage and the EPA estimated KWH/year is 4775, but that's for a whole family.
