Both of these will allow for use of 30% up to $1500 tax credit.

I hear awful things about on demand heaters, especially with hard water.

Further on demand claims only a $50 less per year water bill. I would imagine I will save $50 alone just in switching from a pilot light ignition heater to an electric ignition heater (which the power vented one is).

Further, on demand will require me to get a new gas meter, as my limit is 275 CFH (275CFH - 150K [on demand water] - 20K [stove] - 40k [Clothes dryer] - 110k furnace] = -45). Without the on demand I've got about 65,000 BTU to spare.

My goal is to vent out the side of the house to get rid of the chimney for purposes of adding a closet and finishing attic.

Does this seem like a no brainer? I can also "upgrade" from a 40 to 50 gallon heater while I'm at it.

Water heater

The power vent unit is the best choice if you have hard water and need to stay within the limitations of your gas service. With 65,000 btu left on your gas service, you can get a 50 gal heater. You will need a 115vt electric socket installed within 6' of the heater for the electronics and fan. Good Luck

Thanks, I didn't explain well - 65K remaining actually includes the 40K BTU for the (existing) water heater and that is what the new one uses as well, so we are all set. Electric is already right there also!
