Re: [GBlist] tankless water heaters

Brian I thought the Takagi was off the market now, sure didn't know that
Aquastar had taken it over.  In any case, I would definitely get make-up
air for it from the outside not from inside your house.  I would also
consider isolating it in insulated space and put in a damper over the
opening required for the make-up air.  Just make sure it doesn't freeze.
We installed our Aquastar this way and it works well.    Sacie Lambertson

"I'm looking to install a propane-fired tankless water heater in our
off-grid house now under construction. I'm particularly interested in the
the Takagi TK-1 (aka Aquastar 240 FX) because of its high output.  Its
specifications show that it requires 110v ac power, at a maximum of 0.8
amps for electronic ignition and computerized controls.  Apparently a power
vent exhaust would use additional electricity.   This model is not
direct-vented, so I'll have to supply fresh air for combustion via vents
from the outside or from other rooms. "
