Which is the best solar water heater pipe connection

With solar dedicated plumbing, what kind of solar water heater do you want to install? If you want to have hot water in winter, install a flat panel solar water heater, and take antifreeze, and you will not freeze if you have hot water in winter! You can also contact me and I can do technical guidance!

I'm an engineer for a solar producer.

Under normal circumstances, the upper and lower pipes of the solar water heater share the same pipeline, because there is generally no need to use hot water in the process of water supply, so the upper and lower water pipes are actually the same. If you are a user south of the Yangtze River, because you don't have to consider the problem of frost protection, you can use PPR hot water pipes, or aluminum-plastic pipes, of course, you can also use PEX and PERT pipes with better frost resistance.

Hope the above can be helpful to you.

You don't go into detail enough There are only 2 types of solar tubes, 1 is ppc electric heating connection, both hot and cold are OK, and 1 is the hose. Generally hot water about that kind of good. In terms of quality, he 2 is not a type of service life ppc is used for a longer time, but it can't withstand freezing The key is to see what your pipeline site is like to see which one is most suitable If the community is generally soft from each house generally mixed depending on the matter Remember that PPC should use a good pipe A.D. Jinde Rifeng Rifeng Rifeng uses more Pay attention not to buy fake hoses are good or bad Remember to set black insulation cotton Mainly to prevent direct sun powder Insulation is basically useless Good no bird Hey forget to help you.

Oh yes. Which part of the pipe connection do you want to ask?

Water pipe. From the perspective of environmental protection. PPR pipes are composed of carbon and hydrogen, which have no toxic and harmful components, and are safe and hygienic. In addition, the PPR pipe adopts hot melt connection technology, and the pipes are completely integrated together, so once the installation pressure test is passed, there will be no water leakage again, and the reliability is high.

PPR pipe is the hottest water supply pipe at present, PPR pipe has good heat resistance, long-term use temperature can reach 75° is no problem, instant use temperature can reach 95The insulation effect of PPR pipe is also good. In addition, it is corrosion-resistant and lightweight.

2.PEX tubing.

At present, today's market will use PEX as a solar sewer pipe, note that it is because of frost resistance, **low. In order to win the market, many manufacturers have reduced their cross-linking degree a lot, thereby reducing the cost, and at the same time, its frost resistance has also been reduced. Therefore, it is recommended that you choose a good quality PEX cross-linked tube, provided that it is not cheap.

How to choose the material of the solar water pipe.

1.Solar water pipe size.

Normally, the size of the solar water pipe is 20. It is necessary to install which type of water pipe is installed according to the size of the water flow in the customer's home. Before installing a solar water heater, you can ask a solar water heater seller to come to you to design it.

2.Solar water pipe repair.

What to do if the water pipe bursts in winter:

In the case of solar energy in winter, two things should be paid attention to: 1Frequently wipe the dust off the outer wall of the solar glass tube to increase sunlight intake, which in turn raises the water temperature 2

Pay attention to the solar pipeline do not freeze bad, the pipeline is easy to cause accidents after the frozen water flows out (flooding neighbors, water into ice and falling to kill and injure pedestrians and vehicles, solar energy without water is easy to be blown down by the wind, the consequences are unimaginable), the solution is to install heat tracing and insulation layer on the pipeline, it is best to use the pipeline to empty.

3.Solar water pipe insulation.

It goes without saying that the use of materials for thermal insulation is a must. There are many types of pipe insulation materials, on this basis, add a heating belt on the pipe, you can also contact the solar water heater factory to solve it, the heating belt can heat your pipe, plus the insulation material insulation can completely solve this problem.

4.Installation of solar water pipes.

Generally, there are two solar water pipes, one is the hot water under the cold water, the second is the overflow pipe, the first one should be connected to the indoor mixing valve, the general mixing valve has the function of water supply and adjusting the hot and cold water, and the second one is directly from the solar overflow port Next, placed next to the indoor floor drain, the effect is that the solar water is full and flows out of this pipe.

At present, the materials of solar water heating pipes on the market mainly include copper pipes, galvanized pipes, stainless steel pipes and other selling chain materials, and the advantages and disadvantages of these materials:

First of all, copper tube is one of the most widely used materials in solar water heaters, with good thermal conductivity and corrosion resistance, which can guarantee the quality and temperature of water. In addition, copper pipes also have good strength and durability, which is suitable for long-term use in solar water heating systems, but it is relatively expensive.

Secondly, galvanized pipe is also a commonly used solar water heating pipe material, and its advantages are mainly reflected in the relatively low level, which is easier for ordinary families to bear. Galvanized pipes also have high aging resistance and corrosion resistance, which is suitable for use in atmospheric environments, but the control of water quality and temperature and midstream is relatively inaccurate.

Finally, stainless steel pipe is a high-grade material in solar water heating pipes, which has good corrosion resistance and strength, and is suitable for use in high temperature and high pressure environments. The service life of stainless grinding and rolling steel pipe is long, which can meet the needs of long-term use, but it is relatively expensive.

In summary:The selection of solar water heating plumbing materials needs to be considered according to the actual situation, including factors such as budget, water quality and use environment. Although copper and stainless steel pipes are **high, they can ensure the stability of water quality and temperature, and are suitable for families who need high-quality water.

Although the galvanized pipe is lower, the control of temperature and water quality is simpler, and it is more suitable for some small families. In the end, you need to make the best choice according to your actual situation to ensure the good use effect and life of the solar water heater.

Choose the copper talk reputation tube

Copper pipe is a traditional solar water heating pipe material, which has good thermal conductivity and corrosion resistance. The inner wall of the copper pipe is smooth, which is not easy to attach impurities, and is also convenient for cleaning and maintenance. Stainless steel pipes have excellent high temperature resistance and corrosion resistance, and are also relatively strong and durable, but their thermal conductivity is relatively poor.

Generally speaking, high-quality solar water heating pipe materials need to have the following characteristics: first, good heat preservation, which can effectively prevent the water temperature from dropping; Second, it is resistant to high temperature, able to withstand long-term high temperature irradiation, and is not easy to age; the third is corrosion-resistant, which can withstand the corrosion of water quality; Fourth, it has good pressure resistance and can withstand the impact of water pressure.

Generally, the commonly used materials for solar water heating pipes include galvanized steel pipes, stainless steel pipes, copper pipes, etc. Among them, galvanized steel pipes are cheap, but easy to rust; Stainless steel pipes are durable and corrosion-resistant, but they are high; The thermal conductivity of copper pipes is good, but the price is also high.

OK. 2. Use solar water heaters, gas water heaters and circulating pumps in series.

The outlet pipe of the solar water heater is connected to the inlet of the gas water heater after passing through the circulating pump, and the outlet pipe of the gas water heater is connected to the household hot water pipe network. The end of the domestic hot water pipe network is connected to the return pipe of the solar water heater. When the sun is full and the water temperature of the solar water heater is high, turn off the power and gas source of the gas water heater (do not close the water valve), and the domestic hot water system uses the hot water supplied by the solar water heater without energy consumption.

When the sunlight is insufficient or there is no sunlight, and the water temperature of the solar water heater is low, turn on the gas water heater to heat, and the fire power can be adjusted according to the temperature of the inlet water of the gas water heater, which is more energy-saving.

Solar water heaters.

There are also many options for installing water pipes nowadays, such as:

PPR water pipes, copper pipes, copper-plastic pipes (aluminum-plastic pipes), PVC

pipes, iron pipes, and so on.

In fact, from various factors to be considered, PPR

Water pipes are ideal. The reason is also very simple, first of all, it is good.

PPR water pipes are reliable in quality and can be completely comparable to copper pipes; There is also ** is more acceptable, much lower than copper pipes; It is also important to be healthy, without any rust and patina.

Note that the water pipes must be.

6 points. PPR water pipe is divided into cold water pipe and hot water pipe, the key is that the thickness of the pipe wall is different, it is recommended that everyone use hot water pipe at home to discharge, the pipe wall is thicker, the quality is better, and the price is not much expensive.

Considering that the solar water supply and water pipes must be freeze-proof, that is to say, they cannot freeze and crack under normal circumstances, there are only three kinds of pipes on the market: real PEX cross-linked pipes, PERT pipes, and PB pipes.

At present, most of the market will use PEX as the upper and lower water pipes of solar energy, because it is frost-resistant, and it is relatively low, but in the past two years, many manufacturers have reduced their cross-linking degree in order to win the market, thereby reducing the cost, but at the same time, its frost resistance has also been greatly reduced, if used, it is recommended that you do not choose less than 140 yuan; Pert is frost resistant better than PEX, but the cost is relatively higher, so there are few solar energy on the market now; The PB pipe should be said to be the best antifreeze pipe on the market at present, and now many high-end floor heating projects are in use, of course, its cost is higher, and it cannot be promoted in the solar energy industry at present.

Therefore, it is recommended that you choose a good quality PEX cross-linked tube, provided that it is not cheap.

PPR can never be used as a solar water supply pipe, it can freeze and crack in a winter in the north (it can be used in the south), we have used the best, not the original.

Aluminum-plastic pipes are not good, Foshan Rifeng, Jinde have been used, the north and south of the Yellow River will be used for four or five years, and the northeast may be two or three years.

But indoors, for the sake of aesthetics, and the indoor temperature is also high, you can choose PPR or aluminum-plastic pipe.

Answer: There are many options for installing water pipes in solar water heaters, such as PPR water pipes, copper pipes, copper-plastic pipes (aluminum-plastic pipes), PVC pipes, iron pipes, etc. In fact, PPR water pipes are ideal for a variety of reasons. The reason is also very simple, first of all, a good PPR water pipe is very reliable in quality, which is completely comparable to copper pipes; There is also ** is more acceptable, much lower than copper pipes; Another important point is that it is healthy, without any rust and copper.

Hello, <>

According to the position where you install the water heater, connect the hot and cold water pipes, and add valves to the cold water pipes or cold Zhaozai Reshan Chai Xiang water pipes, so that you can switch with the water of Tai Neng Yang at any time, and it is also convenient for maintenance.

The first is to install a three-way switching water valve, which can be adjusted and switched according to the needs of the use through the tung type portable switching water valve.

The second is to install a tee, and the water heater rental number and the solar water heater are respectively equipped with a local volt control water valve.

The first is to install a three-way switching water valve, and adjust the switching state by switching the water valve according to the needs of use.

The second is to install a tee, and the water heater and the solar water heater in the town are respectively equipped with a sail control car water valve.

What is the function of the tube in the solar water heater Hello dear, I am glad for your question: The vacuum tube of the solar water heater mainly plays the role of absorbing heat and keeping warm The vacuum tube has the role of absorbing heat energy. Vacuum tubes are generally composed of vacuum glass tubes.

After the water absorbs heat in the vacuum tube and heats up, the hot water above enters the water tank, and at the same time, the coarse cold water in the water tank enters the middle and lower part of the vacuum tube to form a natural circulation. When the ambient temperature is relatively low, the thermal efficiency of the delayed vacuum tube is higher than that of the yard peiyou, which is due to the good thermal insulation performance of the vacuum tube itself and is not afraid of freezing, so it is suitable for the ambient temperature of 0°. Cons:

Seals that do not have a blowdown function and vacuuming are easily damaged.
