My pool builder uses Jandy equipment. I think PoolDoc doesn't prefer/recommend the Jandy (Zodiac) brand, but that's what my builder used, and because he uses Jandy, my equipment warranty is 3 years not the standard 1 year. Works for me!

While my SWCG's sensor failed a few months ago, I haven't had any issues with the Jandy heat pump. It just works. We use it year-round, but only 1 or 2 times a week. In the summer, I may fire it up to heat the spa. In the winter I still use it primarily to heat the spa, but we used it occasionally to heat the pool, too (though I found that using a "bubble-wrap" pool cover did a very good job of heating the pool during this past winter, so we only heated the entire pool during the holidays or when a family member was visiting us for an extended stay.

The Jandy heat pump is pretty simple, really. Two buttons to turn it on, one for the spa, one for the pool. Set the temperature you want and it turns off when it gets to that temperature (turns back on when the pool water falls below the preferred temperature).
