Really? My wife and I take 2 good showers every morning and we've never ever run out of hot water. She takes her's first then me.
Even if from time to time we did manage to run out it would not justify the expense of buying, installing and operating a propane tankless water heater.
So two things:
1. An electric water heater has a 'tank' and water will eventually run out at some point if you keep using hot water for a certain period of time VS tankless water heater where that does not happen. I did not say that you will run out of hot water after 2 showers.
2. I made no comments about justifying the cost of a tankless water heater.
Decision with going with a tankless is based on several factors like, family size, how much hot water is utilized, can you wait a littler longer (20 sec or so) for the hot water to reach the faucet? Do you want to make room for other stuff and get rid of that big tank, how good was the sales pitch of the guy selling you the product etc
