I've gotten 4 therm gas bills for most summers. Oddly enough my pilot keeps the water hot enough for showers in the summer. Add a therm or so for cooking on the stove with no oven use in the summer(don't heat the house), and it comes to about 3 therms per month from the pilot light and I'm getting 3-5 min daily showers off that pilot too. I use a 1.25GPM showerhead and a flow valve, it provides a reasonable shower when turned to about 1GPM. Anything less and the water don't hold solid streams out of the head. So it keeps up to a month of about 150 gallons of hot shower water, water from the kitchen sink and 6 gallons per dishwasher load about once a week.

300,000 BTU/month / 31 days / 24 hours = 403. Seems 400-500BTU/hr is a good figure. The water heater was installed in 2008. 36 therms per year. If we figured 4 therms per month, that's 48 therms per year.
