I was thinking of replacing my NG water heater with one of the new
tankless ones until I saw the price, about 2K bucks installed. I took
a look at my gas bill for the summer months and figure my current
water heater is costing me about $220 a year to operated and from the
manufacturere info I could save 10 to 20 per cent if I got with the
tankless unit or 22 to 44 dollars a year. Am I missing something here?
This doesnt seem worthwhile at all. The thing would probably need
replacing before I ever reached a break even point.


No, you aren't On top of the numbers you posted, you also have to take into
account that tankless heaters require recurring maintenance and will liely
require a larger electrical service or gas supply.

That's why 99% of the residential hot water systems in this country are storage
tank.

There are situations where tankless heaters make sense, but overall economics
rarely favor tankless.
