I can afford one but wouldnt buy one. its not just a matter of the up
front cost. our incoming water is near 40 degrees after zero weather.
for tankless we would need 2 high btu tankless in series. and a new
gas line to the other side of the street, the entire incoming line and
meter are too small for the flow.

but even if it were all upgraded at a cost of 5 grand i wouldnt want
waiting for hot water, or wasting water every time we turn it on, or
in a power failure having no hot water, let alone in this day and age
the tank water might no be tasty, but drinkable if terrorists somehow
took out the water system.....

geez my 50 gallon 75K BTU tank serves us very well, and frankly the
projected savings isnt worth the draw backs

I should not have said you cant afford one, that was wrong. But you
can get a 460$ Bosch as I did and leave in your old tank to temper
water. Even so 90f rise gets me a fine hot water shower with 34f
incomming. Did you ever actualy measure the shower water as it exits
the shower head, I need only maybe 106f, thats a 66f rise for you,
even if you need more its the units capicity if you use a standard not
full flow head. I use mine without the unit on high but maybe 80-90%
on. My gas supply was fine as is, I switched from electric to gas
tankless and just ran 3/4". Only with a manometer test will you know
supply is inadequate. A power failure, mine uses battery ignition, 2 C
cells which last so far 1 year. Wait for hot water, I wait maybe 5
seconds more, you still with your tank have to push out cold water in
the line. 5000$, mine installed cost me maybe $900 and my payback is
4-5 years.
