The cost savings can be quite substantial too. Here’s one example - let’s say you have a single speed 1hp pump - a 10,000 gallon pool, with an energy cost of .12c / Kwh running 6 hours a day for the summer (4 months) - you are looking at an energy cost of $210 / year. With a variable speed pump, you’re looking at an annual bill of $18 with the same parameters. That’s a savings of over $190 / year! Check out the calculator at Pentair’s website to figure out the potential savings in your scenario.
The downside to the variable speed motors is the upfront cost. They tend to cost around $500-$900, roughly double what a non variable speed motor costs. To help with this, many manufacturers and energy utilities are providing rebates to help you with the cost. Here are some that we found at the time of publishing this article. Do a quick google search to find out if there are incentives available in your area. Here are some great incentives that we found:
