Hallerb, my Bosch 117000 btu unit has a payback of 4 yrs, I save 20$ a
month, in summer my total Ng bill is now 6$ and that includes cooking
and Ng dryer. I used a 1/2" pipe, no additional work. Tankless are the
way to go, to bad few know the facts.

last time I checked the energy guide label a regular hot water tank
barely uses 20 bucks of gas per month, so please explain how you save
20 buckjs a month? unless you convered from electric to gas
tankless....?
