Look into Bosch, Takagi or Rinnai, efficiencies go to 94% and energy
factors of 90+ the best Sears for example gas tank is only 63 energy
factor. Takagi and Rinnai make commercial grade units also with remote
thermostats, I have a small 112000 btu Bosch and it heats 35f incomming
for a hot shower not even set to high. You will save alot with a Ng
tankless, I save 25 a month over electric tank.


Only thing holding me back is the simultanious need to replace most of the
gas piping in my house so that I can get enough fuel to the fire. An
additional expense tipping the ROI out of favor. Perhaps I will have the
guts to DIY that someday.



I should've asked a better question: Do these units need to be located right
at the place where they're used? If no, and they can go in the basement, why
would the piping be so expensive? Your heating contractor can install it,
and based on my experience, they're usually cheaper than plumbers.
