One big water tank or two separate tanks

[Wilson Rith]

Bought a duplex last fall. I share a 70 gallon tank water heater with the tenants that needs to be replaced. There was enough hot water to go around for the most part with the 70 gallon tank, but I’m leaning towards the idea of getting two separate 40 gallon tanks so we don’t have to worry about sharing hot water with the tenants.

I haven’t received a quotes back yet from the company that serviced the tank, but I’m thinking for the one tank it should cost 1500 to 2000 to do the job. And for two tanks I’m looking at 3000 to 4000. Does that sound right?

Thank you.
