Pools can increase electric bills several ways:

The pool filter pump is typically the biggest energy user, accounting for 90% or more of total electric energy.

Electricity use is a function of pool volume, type of pump (single-speed vs. variable speed), and type of filter media.

RANGE: $415 - $900 per year

Some heated pools use natural gas. Most backyard pools in Pima County are unheated or heated in Spring and Fall to extend the swimming season. Most of those that are heated use solar power.
