Home Solar Water Heater (compact non-pressurized system) Galvanized
SF-1800-58-470-12-SCN 100L , 25mm diameter hail resistance
Thermosyphon solar water heater (compact non-pressurized system) is
comprised of three parts: water tank, vacuum tubes (collector), and
Working principle: Non-pressure solar heating is a kind of solar
water heating systems that the bellow collector directly connects
with the above water tank.
This solar water heater do not need to run the pump to force and do
not require pipeline connections between the collector and the
water tank. It is a simple and secure way to collect solar energy.
The working principle of solar water heater is to make a natural
circulation between the water tank and the collector.
a. The high quality vacuum tubes absorb the solar ray to heat the
cold water in the vacuum tube.
b. The hot water rises in the top of the water tank from the vacuum
tubes, and the cold water from the water tank sinks to the vacuum
tubes to be heated by solar collector. So the whole system is
always circulating continuously.
c. You can use a controller or an auxiliary tank to let the water
fill the water tank automatically.
1. Lowest price. Most family can afford it.
2. Highest efficiency. The water fills the whole system, so that
the heat loss is the least.
3. There is no need to wait and the hot water is available
4. Three target vacuum tube: more efficient
Thermosyphon solar water heaters can be used for ordinary families,
Several solar water heaters can also be installed in array to form
a solar project.
