The standby heat for an elec. tank heater at 15 cents/kwh may cost you $65/year. I assume 50w for 8700 hours.
How much you pay for NG, per CCF?
I pay $1.60 per CCF = $1.60 per therm and so my standby for NG would be $23/year.
A therm = 100,000 BTU = 29.3 kwh.
Here's some prices -

Figure on 100 gals per person per day and a bathtub may fill at 6 GPM.

Thanks wazzat & nealtw!
When I lived in Indonesia for a year there was one in the house where I stayed. That was 20 years ago and I didn't pay much attention to what it was but I remember it well. I never ran out of hot water. Ran out of water once in a while when they didn't fill the water tank though. It never failed but was kind of ugly inside the western style bathroom.
I've talked to a couple plumbers and they aren't very pro-tankless. Have either of you used one? I'd sure like to hear some firsthand experiences.
Thanks guys!
