When you bought your swimming pool, you knew the summer fun involved additional costs. First in line is the cost of the pool. Next there is maintenance and pool chemicals. Then you received your summer electric bills.
You cannot eliminate the electric costs of running your pool, but you can minimize them. Swimming pool pumps consume a lot of electricity, second only to home air conditioning. Is your swimming pool pump sized correctly? The larger the pump the greater your maintenance costs will be. Most private residential pools require .75 horsepower pumps or less. Consider the following chart.

10 174 262 334 460 597
