Description
Energy Conservation Solar Water Heater Features:
1) Inner and outside water tank shell all are made of SUS3042B food grade stainless steel plates, welded by argon arc. Water is pure and drinkable
2) Heat insulation of water tanks adopts polyurethane foam and the thickness is 55mm
3) Silicon rings to connect and seal them
4) The tubes and supports are adjustable. The power bearing is average and can assure the vacuum tubes to use for a long time
5) Whole glass vacuum tubes adopt super hard borax and silica glass
6) Absorption rate: =93%, thermal radiation rate: =6%
7) It resists 25mm hail and the using life can last 15 years
8) Temperature when exposed to sun without water: 250oC, 2.5 hours to boiling point if using single tube
9) If you use electrical appliances to aid heating and to switch off the power supple before bathing
10) Please test the water temperature before using, in order to avoid scalding
Working Theory:
Since the density of hotter water is much small than colder water, the hotter water is always floats upon colder water.
The coat of vacuum tube absorbs solar irradiation to warm water inside tube, hotter water rises from tubes to storage tank, and the same time colder water in storage tank sinks down to vacuum tubes, this natural convection will last till the water in whole system reaches the highest temperature due to local solar irradiation and duration in a single day.
Advantages:
The most economical solar water heater for domestic hot water;
Simple structure with very easy installation and pipeline connection;
INLIGHT argon-arc welding and in-house testing ensures a long lasting tank without any leakage problem;
INLIGHT makes a high-density integral PU insulation layer for a long time heat preservation 75~80 hours;
INLIGHT solar vacuum tube is made of high borosilicate glass with stable performance and no blasting problem for 15 years;
INLIGHT stainless steel frame for both slope and flat roof installation, with stainless steel fastener to protect device from rusty problem;
INLIGHT non-pressure solar water heater can be equipped with many optional devices to make an automatic-operating system;
We install sample solar water heater for every order before delivery to ensure no mistakes or missing parts for customers.
Optional Device:
Assistant tank, a device installed on top of storage tank, with a float ball valve inside to control water refill for storage tank automatically.
Electrical heater, an electricity based heating device installed in storage tank to assist solar water heating in cloudy or rainy days.
Intelligent controller, a device with sensor and valve for automatic water refill and temperature display, if necessary control electric heater.
Anode magnesium: A device installed in hot storage tank to effectively prevent solar system from generating water scale.
