I've had a heat pump in Maryland for 6 years. It cost more than double the price of a propane heater. Now it needs a $1500 repair, and I'm going to get rid of it and switch to propane. For me, I think the up front additional cost was greater than any savings I may have had from using a heat pump. With the house and pool using electricity, I can't say how much it cost to run the heat pump, but I doubt I saved at least $500 per summer, and it only lasted 6 years until the expensive problem. What I dislike is that it only raises the pool temperature a few degrees per day, even running nearly 24 hours per day and using a cover. Last fall, it couldn't even maintain the temperature at the end of the season. I need to run my pool a lot more than I would run it with a more powerful heater, so this is an additional cost. Whatever you choose, the solar cover was a big help, and they don't cost much.
