Just got my pool finished and located this place with a wealth of information. I'm in the market for a pool/spa heater heat pump. I'm leaning toward Hayward for several reason, one it extends my warranty because I have thee Hayward components and two I have Hayward automation. I'm leaning towards the Hayward/Summit SUM8TA 140,000 BTU. I know it's larger than I need but I'm looking at a little faster heating = less run time = lower electricity bill. I'm aware that gas is much better for faster heating but I don't have gas and would have to bury a tank and from what I understand gas can get expensive, I'm looking to heat the entire pool not just the spa. Anyone have any experience with the Summit line of heat pumps?
