Probably true.

But it might pay for itself in energy savings plus water savings.

It would cost me more. I can just about guarantee that we would use more water if we never ran out of hot. Even with a 50 gallon tank, SWMBO and I can empty the tank when taking a shower, either separate or shared.

Heck, on a lazy, winter Sunday morning, we'd probably stay in the shower until noon. ;-)
