Thermosiphon - SUNSIPHON
Manufactured by SunEarth Inc. at 4315 Santa Ana Street
in Ontario, CA 91761. This is a high performance
passive system with no pumps or controls.
The thermosiphon
design allows the natural heat convection movement
to provide circulation between the solar collectors
and the solar tank.
As the sun strikes the collectors copper absorber,
the fluid rises to the top of the collector, exits
the collector and
enters the top end of the storage tank.
The solar
tank is marine grade stainless steel for long life.
The system
uses
an edible glycol solution between the collector
and solar tank loop for freeze protection.
This is the
state of the
art for passive solar hot water systems. 10 Year
Limited Manufacturers Warranty. Click

Active
Domestic Hot Water System -
Manufactured by Heliodyne Inc. at 4910 Seaport Avenue
in Richmond, CA
94804. An “active” solar
system uses a pump to circulate water between the solar
collectors and a separate solar storage tank located near
the conventional
back-up water heater.
In most cases, the solar
collectors are located on the roof. Appropriate plumbing
connects the
solar
collectors to the pump and control.
The differential
controller has two sensors; one on the collectors and
one located
at the bottom of the solar storage tank.
Whenever the collector
sensor
is hotter than the tank sensor the system turns on.
When the bottom of the tank reaches 160 degrees the system
turns
off.
One of the key benefits to the active system is that
the individual components are easy to replace.
The
pump and controls
are warranted
for 18 months, the solar tank for 5 years. The Gobi
collectors carry a 10 Year Limited Manufacturers Warranty.
