Our premiere line of Solar Systems are characterized
as drainback, indirect, active systems.
- Drainback systems are equipped with a small fluid storage
tank used to collect the fluid media from the collectors,
and collector loop plumbing, when the pumps is not running.
In other words, when the temperature on your roof is not
warm enough to heat water, all fluid is drained into the
storage tank to assure that the system cannot freeze.
While the collector on the roof is empty the back up heating
element wiil heat your water at the desired temperature.
- Indirect (closed-loop) systems use a heat transfer fluid
(water or diluted antifreeze) to collect heat and a heat
exchanger to transfer the heat to household water.
- Active systems use electric pumps, valves and controllers
to circulate the heat-transfer fluid through the collectors.
The drainbackSolar System is our most popular solar water
heating system and an intelligent choice for climates susceptible
to freezing temperatures. In addition, it easy to retrofit
because their storage tanks do not need to be installed
above or close to the collectors.
Proper sizing and selection of your system will insure
years of trouble-free hot water service to your home. A
good rule of thumb for sizing your system consists of two
parts; Collector size and Solar storage.
Collector size is calculated at about 20 ft² of collector
area for each of the first two family members and 8 ft²
for each additional family member if you live in the south. |
