Keeping things simple... usually works best.
Going GREEN with today's Tankless heaters reminds me of my "solar water heater " days. It's all the same "tall tales" on energy savings, the same "fuzzy math" on payback, and the same "tax credits " to convince you to buy one.
l really love trees too, but folks, you are not going to save the planet by getting a tankless water heater.
It is much wiser to take that money and put more insulation or better windows in your home. I can 100% guarantee that you would see a dramatic savings doing this vs $3800 into a tankless water heater.
If you really have the need, desire, and urge to feel "all green and fuzzy" about yourself, why not save that money and just go out in your back yard and plant some trees??.
If you absolutely must do something green, planting trees for future generations to enjoy would be a much more "green" and rewarding thing to do instead of throwing away $3800 for a tankless heater.

1. The payback
takes 22++ years!! This is totally insane, you might save up to 8 bucks a month !!
Folks, the numbers don't lie.
If you live in your home till the day you die, once you add in the de-scaleing costs, you can never break even!
----------------------------------------------------------------------------------------
2. In INDIANA , with BITTER COLD -- ROCK HARD -- LIME --IRON -- MINERAL infested water, they CANNOT MAINTAIN their efficiency without bi-annual maintaince...$$
All brands state in their fine print...
The heating coil should be flushed out with a de-scaling solution and cleaned "periodically " by a qualified service tech to maintain good performance, if the heating coil limes up due to hard water, this VOIDS the warranty!!!
What will it cost to clean the heating coil in your tankless water heater and how often should it be done??
What will happen to your FLOW RATE if the tankless unit is not de-limed "periodically".
Can you "de-lime" your tankless unit yourself once, or twice a year??
Does $250 once a year to de-lime your tankless heater sound economical??
remember to factor in the "de-scaling service" into that huge savings of about $8 bucks a month you get from a tankless heater!!

3. In INDIANA you MUST have a water softener to get lime out of the water. You MUST maintain very low hardness level of your water. http://www.complaints.com/directory/2006/june/14/26.htm
4. Tax credits have been extended to 12-31-11 .. then the fat lady sings.....
you now only get a tax credit of only $500 from the feds....next year ..on your taxes. So you spend $3800 now, for a promise of .. up to the max of $500 off your tax bill ..... next year.
WOW....what a deal.
I'll gladly pay you double tomorrow for a hamburger made today.
Remember Wimpy, that their is no guarantee you will be satisfied with this product.
.5. Finding a repair man for a tankless heater could be very difficult . Finding parts asap could also be fun .
http://www.my3cents.com/showReview.cgi?id=48140
If its going to be a week for parts to arrive or the next appointment for the only good service man in 75 miles is next Friday, you are sunk....sunk...sunk
6 Will you be able to run more than one shower at the same time?? Can it handle that or will you have to modify your life-style and take turns in the bath to accommodate the tankless unit??
Here are more " hard numbers"
