Solar Heaters for Swimming Pools
If you have an above
ground swimming pool, the
new solar swimming pool
heaters are an easy, cost
effective way to raise the
temperature of your pool by
10 degrees or more.
This is often the difference
between a refreshing dip
and the plunge that takes
your breath away.
Solar heaters for swimming
pools are sold as 2’x20’
panels for around $150
each. Two sets of panels 4’
x20’ sell for about $250.

A 4’x20’ panel is enough to heat an 18’-24’ round pool. “Junior” systems are also
available. These smaller 4’x10’ panels are enough to heat a 16’ round pool. A 10 year
warranty is common with the larger 2’x20’ panels.
For areas where the swimming season is year round, or your pool is in the shade, an
additional panel may be needed to heat your pool during the cooler months.
Installation is simple and should take only 30 minutes. Simply connect one hose from
the pool filter to the system inlet, and a second hose between the system outlet and
the pool inlet. Unroll the solar panel and you're done.
Although it isn't necessary to permanently mount the solar panels, plans are available
from the pool dealer or manufacturer to build a platform or rack. Mounting the panels
on the garage roof is also an option.
If you are installing the panel far away from your equipment, you will need to purchase
extra hose.
When you first turn on the panels they will be hot to the touch for the first fifteen
minutes. Thereafter they will be cool to the touch. The difference in temperature is the
heat being transferred to the water in your pool.
While solar heaters can significantly reduce energy costs, there are non-solar steps
you can take to help reduce the heating bill.
One overlooked cost is the power required to run the filter circulation system.
Purchasing a high powered pump will save money. The faster the pump works, the
less time it will need to be on.
Next, make sure you use a pool cover. A pool cover prevents evaporation loss,
particularly at night. The cover traps the solar heat that has been added during the
day. This is very complementary to the solar system. The solar system can be viewed
as actively adding heat. The cover retains that heat passively.
When pool season is over, roll up the panels and store them away until next year. If
you don’t they will freeze and crack.
