this is my second pump the first one was pretty basic one speed. This one is great i have it on 24/7 and you set the speeds by percentage of power or by watts. I also have an electric heater which has a heat pump built in. My pool is an inground 14 by 30 and 6ft deep at the deep end, with this set up it cost me about 75 to 100 bucks. That is the heater set at 75 F and it usually warms up to 80 F on its own on a sunny day

The pump controller is highly intelligent and will auto-prime and throttle itself according to various load conditions. There is a button to allow you to clean the pool at higher suction. The pump will automatically resume normal speed if you forget to turn it off. It also defaults to the normal slow speed when you turn it back on after cleaning the basket anyway. If you are concerned about the significantly higher cost of the pump, there is more to consider than just the savings on the electric bill. The pump runs almost 24 hours a day, though at substantially less power than a single speed pump. Therefore, the water surface is skimmed and the water is circulated almost constantly. The amount of chemicals required is significantly reduced. After an entire season of use and despite the hottest summer on record, the pool has easily been the cleanest it has been in over 25 years.

After first experimenting with using this pump with my existng pool system pump controller I determined that my existing system really did not offer the level of control I wanted. I switched to using the built in pump timer and controller. The built in control is easy to use and offers the ability to program 8 different time schedules, each operating at a different speed. I use all 8 to operate my pump for about 18 hours a day.

We researched pumps comparing between thge 2 speeds and variable speed pumps and went with the variable speed from Hayward. Its so quiet we don't even know its running sometimes. Runs great!
