Solar hot water pipes on top or cold water on bottom

The solar water heater is to first feed the cold water into the hot water storage tank, and then deliver the heat to the insulated water tank through the collector.

Solar water heater is a device that converts sunlight energy into heat energy, heating water from low temperature to high temperature to meet the use of hot water in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters according to their structural form, mainly vacuum tube solar water heaters, accounting for 95% of the domestic market share. The vacuum tube household solar water heater is composed of heat collector tubes, water storage tanks and brackets and other related spare parts, and the conversion of solar energy into heat energy mainly relies on vacuum collector tubes, which use the principle of hot water floating and cold water sinking, so that the water produces microcirculation and achieves the required hot water.

The solar water heater is to first feed the cold water into the hot water storage tank, and then deliver the heat to the insulated water tank through the collector. The hot water storage tank is connected to the indoor cold and hot water pipelines, so that the whole system forms a closed loop. Well-designed, properly connected solar pipes are critical to the optimal functioning of the solar system.

Solar pipes must be insulated, and heat tracing needs to be laid on the outer wall of the pipes in cold areas in the north to ensure that users can also use solar hot water in the cold winter.

What's going on with the hot water from the solar cold water pipe Hello dear, reason 1: The vacuum tube is broken empty-handed. If you do not use water for a long time, such as business trips and travels, the water tank will be in a state of high temperature and high pressure for a long time, which will make the aging of the sealing ring, accelerate the aging and shrinkage of polyurethane, and sometimes the exhaust is not smooth, and the pressure is too large to make the water tank swell, and it will form scale, shorten the life of the water tank.

Reason 2: High water pressure in tap water. Nowadays, people always do not care very much about their household appliances, such as water heaters, in addition to maintenance, we should also pay attention to its environmental sanitation and temperature changes, now we use water heaters gradually increase the frequency, at this time we have to pay attention to the water pressure, in order to lose the loss of water pressure is too high.

Hope it helps. If my answer is helpful to you, please give a thumbs up (in the lower left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress. Finally, I wish you good health and a good mood!

Summary. The upper and lower water pipes of the solar water heater are not the same, and he has two pipes, the cold water inlet pipe and the water heater inlet and outlet pipe, and everyone must make corresponding differences when using it. Adjust its switch position to prevent adjustment errors and seriously affect the normal heating of water purification, water and solar water heaters.

Hello, dear, after inquiry, the solar water pipe and the hot water pipe are one.

Tank inlet and sewer pipes of a solar water heater with an automatic controller installed.

The upper and lower water pipes of the solar water heater are not the same, and he has two pipes, the cold water inlet pipe and the water heater inlet and outlet pipe, and everyone must make corresponding differences when using it. Adjust its switch position to prevent the adjustment from making mistakes and seriously affecting the normal heating of water purification, water and solar water heaters.

Because the solar water and the dust are both pipes, the cold water flows from the water pipe.

The most fundamental reason for the heat of the water supply pipe is that the "water supply pipe" of the tap water and the "water pipeline" of the hot water share the same pipeline. And the tap water pressure is too small, even less than the downward pressure generated by the manuscript beam under the action of gravity of hot water.

When the temperature set by the user is lower than the temperature of the pipeline, the circulating pump will sense the start of work, and the cold water of the pipeline will flow to the solar water heater through the return pipe, if there is no return pipe, the water from the hot water pipe will be directed to the cold water pipe, and then flow to the water heater for circulating heating.

At this time, the cycle time can be delayed for a period of time according to the user's setting, so that the circulating pump continues to work until the set time, and the hot water flows out soon as the user turns on the faucet.

Summary. Hello you can use a pipe, but there are many hidden dangers, such as in the bath can not be on the water, if 2 pipes, bathing automatically on the water, there is no need to manually water operation, it should be noted that even if there is an inlet and outlet pipe, the position of the two pipes close to the water heater must add valves, otherwise any waterway maintenance and transformation, the water of the entire solar water heater must be released.

Water supply: tap water valve, after opening the valve, the water flows to the water storage tank of the solar water heater because of the pressure and is heated by the solar water heater, when the water is full, there is a pipe back to the water overflow, so that you can judge that the water storage tank of the solar water heater is full, so close the water valve for water.

Can the inlet and outlet pipes of a solar water heater be used with the same pipe?

Drainage: The heated tap water is stored in the water heater storage tank, and when the bathroom shower or hot water valve is opened, the hot water flows down through the previous water supply pipe due to gravity and is supplied to us.

Depending on the type of solar water heater, some solar water heaters have the same pipe for water and some are not. Because of the different structures, flat plate solar water heaters must distinguish between upper and lower water, and vacuum tube solar water heaters do not need to distinguish between upper and lower water, and the upper and lower water can be used with the same opening.

Because of the structure of the water tank, the liquid level of the inlet of the flat panel solar water heater is much higher than the liquid level of the outlet, so it is necessary to distinguish between the inlet and outlet, but both methods are possible.

The difference is that if the same tube is used, there will be problems in the later stage, which is convenient for inspection and maintenance. However, when using water, the water supply and water discharge cannot be carried out at the same time, and there will be an automatic shut-off. This is not the case if a different tube is used, but if it is, it is not so easy to repair.

Summary. It may be that the weather is too hot and the water from the cold water pipes is being heated.

It may be that the weather is too hot and the water from the cold water pipes is being heated.

Can you elaborate on that a little bit more?

If it is not due to the weather, it may be due to the following reasons:1The temperature of the tank is too high:

When the solar water heater is exposed to high temperatures for a long time, the water temperature in the tank may rise, even exceeding the set temperature range. At this time, even the cold water pipe from the solar collector to the water tank can be affected by the heat energy, resulting in hot water in the cold water pipe. 2.

Design or installation issues: There may be problems with the design and installation of the solar water heater, resulting in improper connection between the cold water pipe and the flush hot water pipe, or improper arrangement of the pipes inside the tank, resulting in hot water in the cold water pipe. 3.

Solar water heater service life is too long: After the service life of solar water heater is too long, the performance of the collector, water tank and other components of the tribe may decline, resulting in poor heat energy transfer, resulting in hot water in cold water pipes. In this case, you can consider the following workarounds:

1.Adjust the temperature of the water tank: Adjust the control system of the solar water heater to limit the water temperature in the tank and avoid exceeding the set temperature range.

2.Check the design and installation: Check whether there are problems in the design and installation of the solar water heater, and if there are problems that need to be repaired or improved in time.

3.Replace old equipment: If the life of the solar water heater is too long, you need to consider replacing it with a new one to ensure normal use.
