I am planning to install a heat pump with chilling option for my inground diving pool in Phoenix AZ. I will use a solar blanket when heating the pool.
I would like to make the system as efficient as possible and was told that I may want to replumb my main drain back to the pump area. Currently my main drain is plumbed to the skimmer which may not provided the best circulation when heating. This is a concern of mine since the diving pool is fairly deep.
I believe my installer may also have been suggesting to reverse flow of the main drain.
If I don't replumb the main drain will the heater only heat the top of my pool?
