On Demand Heater vs Water Tank
The house we bought has a rental hot water tank $34/month.
It's a total waste of money, so we're going to replace with a better unit, purchased at a good price from a friend in the industry.
However, I briefly - VERY B R I E F L Y - entertained the idea of getting an on demand unit, mainly to save space in our laundry room.
Until I found out they start at $3600 and go up from there!
What's the payoff? Maybe they have a 5x longer life expectancy to match their 5x+ larger price tag?
