Rental water heaters are some weird Canadian scam.
My ~70 year old water heater failed 5 years ago. I drove to the nearest hardware store, paid $700 for a new one, and installed it myself.
Comparing efficiency between electric and gas is complete nonsense. You need to compare operating cost. In my market, with very high electric prices, it’s $60/yr for gas tank, and $1,100/yr for electric tankless.
This isn’t the first implementation of wordfilters. Fifteen years ago, if I’d called someone a roody-poo candy-ass anywhere other than 4chan, I’d have needed to kms.
