Solar Water Circulators

This issue

Round and round on sunlight

Cover story: a pool turns its water over every sunny day, and a SunRay hybrid does it 100% solar-powered while the light lasts.

Kits from $1,999

Feature: the loop

Water leaves the pool, passes the filter and returns, all day, on panels that come with each kit.

Feature: no outlet in the loop

Inside the loop, no AC is needed for the solar to work.

AC may be added; the circulator moves to it at night by itself.

Feature: the bill

Readers commonly keep $100 to $250 a month.

Up to 30% on the utility bill.
