If the ground you live on is far from the roof, you will need to drain some cold water when using a solar water heater, which can be put into a bucket or other container for washing if you wish eliminate it completely. In this situation, you can install antifreeze. With the drain device, the water from the bathroom connection pipe to the roof water tank is drained, so that when the water is drained, the water from the water tank flows directly in the bathroom. , and of course it will be hot water directly. The cost is around 200 yuan. You can go to a store that sells solar water heaters to check carefully. General solar power can be installed as a device. This device was first used to prevent freezing in winter in the north, but it can be made. the advantages of direct hot water production. In the south it can also be installed andused in various areas to avoid problems with frozen water pipes in winter.
The characteristics of the new solar antifreeze device are: (1) It can be installed and used without changing the original structure of the solar water heater (2) Hot water comes immediately, without necessity; to put cold water, energy-saving and efficient; (3) ) Effective antifreeze in winter, allowing the water heater to serve you all year round (4) The product is exquisite, high quality and low price, suitable; for consumption from all walks of life
The cold water pipe is connected to the cold water outlet.
Solar water heaters have two pipes. Generally, the hot water outlet is on the left and the cold water inlet is on the right. When installing, connect the cold water pipe to the cold water. the inlet and the hot water pipe to the hot water pipe. The mouth is closed and the two interfaces of the water pipe will be equalement marked.
In addition to the upper and lower pipes, the solar water heater also has an overflow pipe, which is mainly used for drainage. When the water heater is full, the excess water will be discharged through the overflow pipe and then simply turn off the water tap.
Working principle of solar water heater
Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural forms. main ones, representing 95% of the domestic market share.
Home evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum tubes which use the principle that hot water is used. floats and cold water sinks, causing microwater circulation to obtain the required hot water.
Solar energy generally refers to the radiant energy of sunlight. Solar energy is a renewable energy source in a broad sense, solar energy is the source of many energies on earth, such as wind energy and biomass energy. , tidal energy and potential energy of water, etc.
The basic methods of using solar energy can be divided into four categories: using light and heat, using light and electricity, using light and chemicals and use of light and biology. Among the four types of solar energy utilization methods, light-to-heat conversion technology is the most mature, has the most products, and is relatively inexpensive.
