If you're gonna spend lots of money on a water tank you might as well
get an oil fired demand water heater. Gives you unlimited hot water and
no cost to maintain a tank of hot water. If you want to put a tempering
tank in your hot attic save even more.

my tankless add on was only for use when familiy is visiting, the
remainder of the time my 50 gallon high btu tank is fine.
now 7 people pile in here, and it can become a problem espically when
incoming water temperature is 40 degrees

Its alot of money to put in a tankless and not get the savings year
around, first you need to get the supply tested with all other gas
apliances running to be sure no upgrade is neded. Do 2 people shower
now at the same time, I dont think you will benefit having a tankless
before a tank and it will actualy cost more to run since both units
burners are probably near in efficency, I put my tankless after my
tank with bypass valves incase my old tank leaks, but i havnt used it
since installing the tankless, the cheap Bosch.

its more of a idle thought, the minor standby losses of a regular tank
dont bother me, and our tank is plenty big enough, except when family
visits. with washing clothes, doing laundry and showering its a busy
hot water using place. and our showers have the flow restrictors
removed.....
but a new kitchen dining room gut job is a lot more likely and
probably better of use of money:) kinda nervous the economy may hurt
our income:( and gasoline is killing my service business
