I am thinking about having some sort of heat exchanger for our swimming pool so that we can extend the use of it during the Spring and Autumn months. Has anyone any knowledge or used /purchased one these for their pool. I am thinking of having a Nirvana Pool Heater. Any information would be helpful. Thanking you in anticipation of your help.
