You may not understand what is happening. Its current situation is as follows: the cold water tank (relatively large) is located higher than the solar water tank. Water can be fed into the solar system via the water mixer, so that it can be used as tap water. Additionally, after the water in the vacuum tube is heated, the hot water becomes less dense and rises toward the water tank. The cold water in the water tank becomes denser and flows to the vacuum tube. The tank becomes hot. These are the upper and lower parts of the water tank. The temperature difference is very small and can be ignored. Installation method: 1. Run a water pipe from the cold water tank to one end of the mixer. 2. Open the bottom outlet of the solar water tank (the upper and lower water outlets, one or two on the top of the solar water tank). the solar water tank ares exhaust ports or overflow ports, (Signal for full water, cannot be blocked)) Direct a water hose to the other end of the mixer, [use the mixer switch ( must have a water pump switch) to supply water by solar power and turn off the switch when the water is full. ]. (If the mixer does not have a water supply switch, a three-way connection should be connected at both ends and a ball valve switch should be connected in the middle to supply water to power solar.); The cold water tank has two ports, they can be connected to a water pump. A tube directly supplies water to the cold water tank. Otherwise, add a tee to the connecting pipe between the mixer tap and the cold water tank to connect to the water pump (add a check valve or ball switch between the water pump and the tee to prevent the water to flow back to the water pump).Instructions for use: 1. If you want to collect water from a cold water tank, simply pump it directly with a water pump. When the water is full, turn off the ball valve switch. It is easier to use a check valve and simply. turn off the water pump. 2. If you collect water in a solar water tank, just use the water pump. The mixer water supply switch is used to supply water by solar energy. When the water is full, turn it off. the switch.
How to connect gas water heaters and solar water heaters when installed at the same time?
A pipe is directly connected to the water pipes upstream and downstream solar panels, and a three-way connection is directly connected to the mixing valve in the middle room.
1. To use home solar energy, you must first open the cold water valve, adjust the temperatureure the appropriate cold water, let the cold water flow out slowly, then open the hot water valve to release the water. flowing water, which mixes with cold water to form hot water. Pay attention to the hot water valve every time. Open it a little less to avoid burns.
2. The water supply for domestic solar water heaters should be determined based on the weather. The water tank should be filled on sunny days, half the water should be filled on cloudy days and not. water should be refilled on rainy days. If there is hot water left in the water tank after use, it should be filled with cold water to cool the temperature to avoid affecting the service life.
Detailed information:
International research tends to use the same materials in heat storage and heat conduction processes to reduce the complexity of the heat exchange system, thus achieving the goal of reducing the cost of the system. The challenge of the future is the research and development of new heat transfer media such as ionic fluids and new heat circulation pipe materials such as metallized plastic pipes.

Add a 3-way connection under the solar water supply valve, one end is connected to the water inlet, and the other end is connected to the water supply valve solar water supply. One end is connected to the gas water heater and a valve is added. When using solar energy, the valve is closed. to the hot water pipe and a 3-way connection is also added, it is very practical.
As shown in the figure below, the outlet pipes of the two water heaters are connected to the pipe leading to the faucet with a tee. A valve is installed in front of the tee and on the side leading to the tee. the water heater.
When using a solar water heater, simply close the valve leading to the electric water heater; otherwise, close the valve leading to the solar water heater; The water supply pipe (cold water) does not need to install a valve here.
The gas water heater, also known asgas water heater, uses gas as fuel and transfers heat to flow through heat exchanger via combustion heating A. gas appliance that uses cold water in a device to prepare water hot.
The solar water heater is a device that uses sunlight to heat water.
Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters which account for 95% of the domestic market share.
