Integrated and pressurized solar water heater I combined the Advantages of Non-pressure solar water heater and separated pressurized solar water heater together. This system adopts heat pipe instead of evacuated tube combined with pressure-bearing storage tanks, this product improves the problems, such as, limited hot water volume, long heat time, few water output etc.The twice heat exchange technology makes the high temperature, high efficiency and fast & large amount hot water circulation come true.

The system can bear certain amount of pressure thus the running water can directly connector with the inlet, when opening the valve, cold water flow through the inlet and then to the cooper coil, the hot water inside the water tank play the role as hot resource and do heat exchange via copper coil with the cold running water, during this process the cold running water been heated to hot water.(The temperature maybe ≤5℃ lower than the hot water in the water tank).All the storage tanks should be tested as tested pressure of 1.2 MPa(12 bar) and the working pressure is 0.6MPa(6 bar).The daily efficiency is over or equal to 55%.

Note: all the accessories (intelligent controller, assistant tanks etc.) can be installed according to different needs.

Specification: (we can customize according to customers’ requirement)

Comments

The basic Non-pressure system SWH is a passive system, which relies on a natural principle-Theermosiphon.There is water in evacuated tubes and free to flow into tanks. When the water in tubes is heated by sun’s rays firstly, this makes water in the tubes lighter.

Therefore the cold water in the tank move downwards and hotter water move upside into the tank. It is an open circuit since the air vent and the overflow pope is open to the air.

All the storage tanks are tested before leaving with tested pressure of 0.05Mpa (0.5bar).But the operation pressure should be 0 Mpa. The daily efficiency is over or equal to 50% normally and 42% in winter. We welds the inner tank by high-frequency ring or argon arc techniques.

1. with intelligent controller
Advantage: automatic supplying water into the tank when the water in the tank is below a certain value.Also.other functions includes water temperature, water level display, auto power-off the electronic heating device.
2. with assistant tank
Advantage: Automatic supply water is conducted through mechanical way by installing an assistant tank (5L,8L and 10L).in addition,com-bined valve could mix hot water with loading cold water fully, preventing shower water now hot now cold.
