--Solar energy from hot attic air.
Advantages:The SolarAttic™ PCS1 pool heater uses your roof and attic as the solar energy
collector. The system takes advantage of solar energy (hot attic air) without having to use any type
of solar panels. To heat the pool, the system converts the heat in hot attic air to warm water for the
swimming pool. Inexpensive to purchase, install and operate. The heat exchanger [PCS1] fits in
the attic, protected from external elements, and invisible from the outside. Cools the attic as it
heats the pool. Non-polluting and renewable -- like other solar energy systems. And, this form of
renewable solar energy does not have the aesthetic problems that are associated with roof mounted
solar panel systems. The PCS1 fits into standard attic crawl spaces that have 3-4 feet inside the
attic from its floor to its peak.
Disadvantages:As with any solar energy application, there is no available energy to heat the pool
when the sun doesn’t shine. In situations where pool waters must be maintained at specific
temperatures, back-up fossil fuel heaters are recommended. Very small homes may not have an
adequate roof or attic space. The PCS1 requires an attic at least as large as the pool’s surface area
which is usually not a problem. In the case of a small attic opening, adequate attic access may have
to be constructed before the PCS1 can be installed which usually involves enlarging the existing
