We will be putting in a pool and spa this summer and plan to install a heat pump. I see that most of the heat pump companies offer at least one model that can heat a spa and a pool. I have looked at the installation info for these heat pumps and have a rather naive question.
The plumbing diagrams for the heat pumps that I have seen show a single return to and a single output from the heat pump. There are valves that connect the returns from the pool and spa to the heat pump, and the same configuration for sending the heated water to the spa and pool.
How does the heat pump monitor and control separate temperatures for the pool and spa? I would think the heat pump would need separate returns and outputs for the pool and for the spa.
Thanks for any help you give to this pool newbie.
