I don't know what that one customer wrote--my Sq120 has a pool option and a spa option. This thing is awesome it heats the spa really quick and hardly makes any noise at all, If I did not feel the water the only way to tell if it is running is to walk over and see if the fan is spinning. I would defiantly purchase again!!

Have an AquaCal for 25years and it is still working! It is a great product with awesome support team. They now have a loyal customer!

My wife needed our pool heated to enjoy it year round in central Florida. I installed this unit Sunday afternoon mid April 2016 and turned it on. No problem at all everything was straight forward. Set temp to 90 as a test with a pool blanket for our 15000 gallon pool. I was pleasantly surprised that the original 72 temp went to 90 in about 36 hrs. I've lowered the temp setting to 80 and enjoying it. This unit is super quite standing next to it. By comparison, my neighbors pool pump is 40 feet away and clearly audible over the SQ 120. Also, had a question and called the customer service number. I got an immediate response and answer to my question on the phone. I'm sold on this product and would recommend it to my friends and neighbors.

Great product, works well, easy to turn on and off and set the heat level.

This heat pump works great!! It heats about one (1) degree per hour, it does consumes about 7.5 Kwh in case you're wondering, I wish it would be a little more energy efficient, but all the other features and the way it heats up the pool is great. I have a 12,000 gal pool so it heats it up relatively fast. I would definitely recommend this heat pump, or any AquaCal heat pump.
