The hot water tank in my house is 20 years old and I think it's time to be replaced. It was bought by the previous owner, so would it be a better deal to buy a new one and have it installed, or rent one from Direct Energy for $10-$12 a month? It's a 40gallon tank, and I don't plan on moving in the near future (not within the next 10 years) I'm sure some of you are experts in this area.
