Snow Melting, Deicing & Gardens
These applications heat the
earth outside by means of plastic heat exchanger tubing. An advantage is
that the operating temperature will be very low and the solar system can
be put to use on cloudy days when the sun is not strong enough to do a
higher temperature application.
The gardening application extends the season, allows the cultivation of plants
and varieties that would otherwise be impossible to grow, helps protect
against frost and makes everything grow better. Again, this use can make
use of low-grade solar energy that is not useful for anything else.
Pools & Spas
This is a good use for excess
solar energy during the summer. It will extend the season for the pool
and keep the solar panels cool. Your roof will be cooler and your air conditioning
needs may be lower as a result.
