10tubes solar water heater
Description:
10tubes solar water heater :Small capacity ,popular for small family use.
This type is a compact non-pressurized system. The design of this type uses
the all-glass evacuated solar collector tubes as the heat absorb element. There
is a natural circulation system that works on a light absorption principle.
Depending on the different density between hot water and cold water, a
water flowing cycle is created in the tubes. Hot water flows automatically
upwards while the cold water flows down. The water in the storage tank will
be heated from this natural circulation.
This model is one of the most favorite on the international market.It was
scientifically and specially designed,is easy to install and operate.The
important point is it can feed water automatically and ensure the outlet water
as stable temperature,it will always provide you hot water.
Thermo siphon Solar Water Heater relies on the natural circulation of water
between the collector and the tank or heat exchanger. As water in the vacuum
tubes is heated, it rises naturally into the elevated tank while cooler heavier
water in the tank flows down to the bottom of the vacuum tubes, causing
circulation throughout the system. Greater height differential will result in
greater flow. Larger pipe, shorter runs, and gentle bends will make for an
adequate flow rate.
