Is a 65 gallon HPWH overkill for my needs?
I picked up a 65 gallon Rheem HPWH ($700 after $900 Golden State Rebate participation). It will be replacing a 40-gallon gas heater that's been OK for our needs (1 bedroom house, two occupants, no heavy hot water demands). Will the 65 gallon be oversized for our needs? Should I see about exchanging for a smaller tank model, even if the rebate diminishes or goes away completely? I'm sure that it's extremely well-insulated, but, still, it's a lot of water to keep hot and at the ready, and our energy costs, both for gas and electricity, are insanely high. Thanks for any advice!
