Talked to my older brother and he replace 2 water heaters with one tankless water heater. He as 3-1/2 baths and 2 utility rooms. He often has guests, his upstairs is two guest suites each with their own full bath and a common laundry closet with a small washer and dryer. He didn't put in the tankless for economy, he put it in because sometimes all three showers and a washer is going and the two tanks would run out and go cold. Says the tankless is big and fast enough that they can run all three showers and both washing machines without anyone getting goose bumps.

I just don't need that much hot water at a time.
