Looks like the Aqua Cal is more efficient than the Raypak but the Raypak is 3k vs 5k for the AquaCal. That 2k would pay for most of a solar heater which might be more efficient overall and have more heating power.

Pool info:
20k gallons in ground
Pentair intellicenter
3HP VS pump
600ish square feet
In central Texas
We do keep it covered.

Check that the company you buy the HP from can service it and has EPA 608 certified technicians who can handle the refrigerant. Seems like many pool companies sell HPs that they cannot service.
