We use very little hot water, so we're going to go with the standard tank. My thinking was that since we don't use very much hot water, it would make sense to not keep a 40 gallon tank hot at all times. It turns out the ROI would be about 15 years. Had it been 5 years or less, I would have given it a shot.

the aspect I like about tankless or other electric water heaters in general is that when solar or wind power becomes more economical for your house (I think it wil in the next 5-10 years). you can be self sufficient in heating your water.
