I live in Michigan and use the pool for 3 to 4 months a year. I have a 20x40 pool with about 36,000 gallons of water. I am in need of a new pump. Are the energy savings of a variable speed pump worth the extra cost? If I only use it for such a short time each year should I even be concerned about the energy efficiency? I am more concerned about the finances rather than saving the planet. Are there other advantages of the more expensive pumps I should be looking for? I don’t like wasting money but if I have the pump for a long time a couple hundred bucks probably doesn’t make much of a difference if I get some value.
