Just a total of around 15 hours. Should mention I also have Solar so that helps with raising the pool temp while heating. I was paranoid with getting a $200-300 heating bill, but again, running the spa about 2 times a week for about an hour or two only cost around $60-70. My neighbor has had a couple of $300 bills, but he has an older 300K BTU heater and no solar, and it takes him a full day to heat the pool. My solar keeps the pool about 10+ degrees hotter than his. Right now he's at 63 and I'm at 78 at the end of a 6 hour cycle with solar. Same size pool and sun exposure...
