Solar stainless steel water heater
Solar stainless steel water heater Solar stainless steel water heaters absorb water by absorbing the heat of sunlight, with zero combustion and zero emissions. They are energy-saving, environmentally friendly and safe. After years of promotion and use, they have become household names. In addition to being used in households, solar stainless steel water heaters can also be used in large-scale hot water supply projects, such as schools, hospitals, enterprises, factories, construction sites, bathing centers, water parks, etc., for daily bathing, washing, domestic water, Production of hot water, etc....

Solar stainless steel water heater is a heating device that converts solar energy into heat energy, which heats water from low temperature to high temperature to meet the hot water use of people in life and production. Solar stainless steel water heaters are divided into vacuum tube solar stainless water heaters and flat solar stainless water heaters according to the structure, mainly vacuum tube solar stainless water heaters, accounting for 95% of the domestic market share. The vacuum tube type household solar stainless steel water heater is composed of heat collecting tubes, water storage tanks and brackets and other related parts. The conversion of solar energy into heat energy mainly depends on the vacuum heat collecting tube, and the vacuum collecting tube uses the principle of hot water floating on the cold water sinking to make the water generate microcirculation. And get the hot water you need.

Solar stainless steel water heater

Solar stainless steel water heaters are generally divided into a forced circulation type and a natural circulation type according to the circulation method:

1. The forced circulation system generally uses a header to connect a plurality of solar collectors in parallel, and then connects the upper and lower circulation pipes to the stainless steel insulated water tank, and the lower circulation pump is based on the temperature difference between the solar collector and the water tank (5) °C~10°C) to decide whether to start: when the water temperature in the solar collector is higher than the water temperature in the water tank, the circulation pump works, pumping the water in the water tank to the bottom of the solar collector, and the heat in the upper part of the solar collector The water is pushed into the water tank; when the water temperature in the solar collector and the water tank is basically balanced, the circulation pump stops working, and the action is repeated to ensure that the water temperature of the required hot water is constant.

2. The natural circulation system is made up of a solar collector and a stainless steel insulated water tank. The liquid level difference caused by the change of the water temperature of the solar collector generates a thermosiphon effect. The high temperature water rises into the upper part of the water tank, and the low temperature water flows into the vacuum tube. This reciprocating cycle increases the temperature of the water in the tank to achieve the desired temperature. However, in the system, the water tank is required to be placed in the upper part of the solar collector and kept at the same level, which is difficult. Therefore, it is generally adopted that multiple households are used in series, and it is not suitable to make a large solar water heating system.




By comparison, the natural circulation type solar water heating system has a small initial investment, low operating and maintenance costs, but the water temperature is slow to increase and the thermal efficiency is low, so it is widely used in ordinary households.


After the forced circulation solar water heating system is put into operation in the early stage, it is necessary to increase the operating cost of the circulating pump. However, the water tank can be separated from the solar collector. The position of the stainless steel insulated water tank is more flexible. During the use, the circulating pump can increase the heat exchange frequency and the water temperature. The lifting is fast, and it can always maintain a high temperature, which is more suitable for the supply of a large number of constant temperature and constant pressure hot water in large places.
