So its our first year with a heat pump. Works great, very happy with it. But I'm also trying to be as efficient as possible with it, since it's most efficient maintaining temps (As opposed to bringing them up). What I've been doing up to this point is running my normal pump cycle for six hours during the day. During that time, the heat pump is set with its thermostat and comes on when it sees water flow. The heat pump runs for about three hours to bring the pool back up the three degrees it lost overnight. So every day, it's working to bring the temps back up.
Pump and heat pump running costs about a dollar an hour. Pump alone costs $.14/hr.
So - if I wanted to leave the heat pump running all the time to maintain the temp through the day and night, I'd have to leave the pump on all the time as well. At $.14/hr, that's $3.36 for the pump alone over 24 hours. Whereas if I let the heat pump run for its three hours, and the pump for six, that only costs about $3.23.
Really didn't expect those results.
Now, if I wanted to take it a step further, I thought about automatic. But every component in my system is from a different maker; I assume the pool installer got deals on whatever was around. So I have an Intelliflow VS pump, Aquacal heat pump, Fiberstars LED lights and Hayward Aqua Rite. I don't care much about the LEDs, but is there something out there that will interface with all the rest AND give me support for the VS pump to actually control it more than on and off?
