Not much I suppose, especially with the 30% tax credit. Say it costs $1600 w/tax vs. say $400 w/tax for an electric. Subtract out the credit and the cost difference and you have delta of about $720.How many cents/kwh does it take to pay back this price within 10 yrs at a COP of 2.0?
Is that the average? Summer? Seems like an awful lot of gas for two. Are you filling big sauna tubs or using high flow (or multiple) showerheads? The highest non-heating season hot water gas consumption I've had in the past 7 years was 24 ccf (this included some regions where the heating season was only 4 months.)The two of us use 35 therms/month for hot water.
It's summer because otherwise the NG also goes into the furnace and so I can't tell. We each use about 100 gals/day. Bathtub, dishwasher, washing machine, 2 GPM showerhead [which I probably will drill out].Is that the average? Summer? Seems like an awful lot of gas for two.

You have links to percentiles for water heater energy used in the US?
Nah, it's a 2200 sq. ft. house.Do you have a housewide recirculation system?
This is awkward, but...
