    Beast of a heater!

    Shipping was great, it arrived on time and looks awesome! It's huge btw, pictures don't do it justice. We had it installed right away and it's working like a charm. Easy to operate and program, runs very quietly. Can't think of one bad thing to say about it.

    Waaaaayyyy better than my old heat pump

    I have been running this on my pool for about 3 months now and it makes a considerable difference compared to my old heat pump. Installation was easy with the help from my buddy and we got it installed in a few hours. It is a very sleek design and is very straightforward. I highly recommend this product for someone looking for a heat pump for a new pool or to replace an old heat pump.
