My house water heater recently failed. The existing water heater was a 50-gallon storage-type gas heater. It’s an older house with no recirculation system. I want to replace the old one with something more efficient, like a heat pump.
The easiest path would be to replace it with the exact same type. It would be cheap and involve little downtime and hassle. It would be a quick fix, and would for good for another 10 to 15 years, but where's the fun in that?
