Absolutely love our new Apollo iGX heat pump! It heats the pool quickly, runs quietly, and has already made a noticeable difference in our energy bills. Highly recommend!

Installed last month and could not be happier. The touchscreen controller is intuitive, the unit is super efficient, and it looks great next to our pool. Smooth operation and very low noise — perfect for our backyard.

Really impressed with the performance of the Solara Series. The side-discharge design made installation easy, and the controller is intuitive and simple to use. Energy bills have already dropped noticeably!
