Yes, the circulator works! It increases the flow of water so you can run your pump less each day and save $$! By moving the water around the pool heat is more evenly distributed and the pool heats faster.

I love the return in our pool. I get colder than most,and that’s where you’ll find me,next to the return! They also make these circular floating rings that are heated by the sun.Look in Outdoors.com. I hate those blankets! They are cumbersome,and the heat from the sun , deteriorates the solar bubbles on the cover.Soon you have a pool full of little plastic pieces,floating everywhere.You need to sweep them out with a net, as those are bad for the pool pump.You never,never,never get them all out.Makes Me Mad! Don’t get one, there a waste of your money!

there are a lot of different ways to heat your pool from a roof pipe connection to a blanket it all comes down to how fast you want to heat your pool the blanket works well but takes a while to heat up the water a pump will work faster but you will use more engery running it i would just get a blanket and put it on and then take it off when your not usein it and then replace it telll you get the right water temp
