So I know heating a pool cost a lot, but If these calculations are within this range it might be ok.
I'm in northern california. our natural gas is provided by PG&E. I checked my bill and found that we pay $1.36 cents to $1.89 per therm, up from 92 cents – $1.40 in 2012. In addition, there is a 4 cents per therm surcharge for “PPP” (per my bill: Gas Public Purpose Program Surcharge: “Used to fund state-mandated gas assistance programs for low-income customers, energy-efficiency programs, and public-interest research and development.”)My calculations come out to $1.63 per therm plus the $.04 surcharge equals a gas cost of $1.67 per therm, on average. A 100,000 BTU heater uses 1 therm of natural gas per hour, so a 400,000 heater consumes 4 therms an hour. 4 therms an hour x $1.67 = $6.68 per hour. So the magic number based on the most common 400,000 BTU pool/ spa heater is $6.68 per hour in gas cost to run your heater. Keep in mind, we’re not talking about how long it takes but how much it costs. So I know heating a pool cost a lot, but If these calculations are within this range it might be ok.
My pool is 25 x 15 but Baja shelf is 5x8 so realistically swim area is I would estimate 21 x 15 and It's 3.5 to 6' deep.

Raising from 60 degrees to 85 degrees and having solar cover. And purchasing a 300K BTU heater it would take 5 hrs. So about $40 to heat the pool. I feel I could live with that for special occasions,
