How does solar work?
A solar hot water system captures solar
radiation through a collector and transfers
that energy to a fluid that flows to your
domestic hot water (DHW) tank. Other
common uses are radiant space heating and
pool heating.
These systems can be installed as a
preheater to an existing DHW tank, or can be
used with a stand alone dual coil tank. The
dual coil tank option would make sense for
someone who is looking to eliminate a costly
electric or gas fired tank.
While a properly designed and installed
system can produce over 70% of a home's
hot water needs, all systems require a back
up to cover gaps in solar production.
