Question 1

How much does a variable speed pool pump save?

Accepted Answer

A variable speed pool pump saves $500–$900 per year compared to a single-speed pump for a typical pool running 8 hours per day. Single-speed pumps run at full power constantly; variable speed pumps run at lower speeds (using the cube law: half speed = 1/8 the power). The DOE estimates variable speed pumps use 65–90% less electricity than single-speed equivalents.

Question 2

What is the payback period for a variable speed pool pump?

Accepted Answer

A variable speed pool pump costs $700–$1,500 installed, compared to $300–$600 for a single-speed replacement. At $500–$900 in annual savings, the payback period is typically 1–2 years — making it one of the best ROI home energy upgrades available to pool owners. Many utilities offer rebates of $100–$400 specifically for variable speed pool pumps.

Question 3

Do pool pump rebates exist?

Accepted Answer

Yes. Variable speed pool pump rebates are widely available from utilities in pool-heavy states like California, Florida, Texas, Arizona, and Nevada. California utilities (LADWP, PG&E, SCE) offer rebates of $100–$400. Florida utilities (FPL, Duke) offer $50–$200. Check the DSIRE database or Enerly's rebate finder for current offers by ZIP code.
