Hello friends, the water temperature of solar panels increases very slowly when the weather is bad. At night, if it is too cold outside in winter, the water temperature in the unit will generally drop. solar panel with water so that when used it is filled with water. It can be washed more often without adding cold water.
The add water button is used to add water by solar power. is only an auxiliary function and does not want to be as fast as a special electric water heater. For example, the water temperature is only 30 during the day and night. You can then use electricity to heat it to 40 or 45 degrees. add cold water. It can be used in general. If the sun is good, it can reach 70 to 80 degrees in a day. In summer, it is normal to adjust the temperature when the pot is on. adjust the temperature to stop heating. What time does the heatinge start? For example, from 3 p.m. and the temperature is 60 degrees, the heating will automatically stop when the time reaches the temperature.
The cycle is activated. the daily cycle you set
中科How about the Sunshine solar water heater? Is the temperature high in winter?
The models are:
Solar water heater collector tube, Sangao Zijin vacuum tube 47*58 *1.8 rice glass tube.

The choice of ordinary three-tube and purple gold tubes
As for after-sales, you don't need to worry about it. there aren't many good stores in China. They sell it and forget about it.
If it's broken, it's hard to repair, so you don't have to worry about which company has good service and which has bad service . service. As long as the price is reasonable, everything is fine.
As long as it's sold, it doesn't matter. This is basically what I encountered
So this time when I bought a water heater, I ordered it online. Sanyang brand is very small, anyway, it is cheaper than the real store, so if you want to buy it, buy the best.
Ground tubesAreas are mainly divided into three categories: ordinary tubes, three high. purple gold tubes and tubes
Let me talk about the prices first. I know
Most of the products sold in China are ordinary pipes. An ordinary 200L pipe costs more than 3,000. Many people don't understand and listen to the nonsense of people selling water heaters. This is obviously the worst in the sky.
The most high-end are the three senior executives.
I really don't know why those who sell water heaters in Guangzhou are so dark
I saw it. Most urban areas are ordinary tubes with a small amount.The three high-end package installed (ordinary 200L costs 3,000). I don't know how much I was defrauded. Of course, it's because of the price in Guangzhou. This is impossible because the prices in Guangzhou are the same. so I have the possibility. Do not buy any after-sales service in Guangzhou. S'it breaks, it can be fixed.
That's bullshit. Is there a store that sells it to customer service. ? You can sign up and I will go and see)
Many people say that solar energy is not good and that there is no water in winter. That's because it's a regular pipe. Do not compare it with a three-cylinder pipe. Not to mention the purple gold level.
In short, ordinary pipes are very poor
But they are very expensive in Guangzhou, so they usually buy ordinary pipes. A lot of people don't buy them. I don't even know the difference between these pipes. That's because the seller deliberately bragged that they were rich.
I've yet to see a few with three-tube purple gold tubes (I don't think I do it). (I've seen them, after all, I don't really see all the water heaters)
Needless to say, ordinary pipes are the ones used lorwhen there is no water in winter
Three-pipe pipes
High temperature resistance, high cold resistance and effective absorption (12% increase in calories) ) When do you get a high fever?
The three-tube high temperature special effect tube is resistant to high temperature and attenuation
● Patented interference coating technology
● The layer absorption is made of stainless steel aluminum nitride, which is resistant to high temperatures, even The glass does not fall when it melts
●It avoids degradation of the performance of heating vacuum tubes -ordinary water that is exposed to air for a long time and has a longer lifespan
●It can also be used in high temperature power generation, refrigeration and desalination sea water
And other areas
Three. -Very cold pipes may still have hot waterfrom to extremely cold temperatures
●Unique ultra pure copper mirror, low reflection and low heat loss
p>
●The inner tube is cleaned, the exhaust process is strict, the vacuum layer is pure
clean and free of impurities, the vacuum degree is high and durable
●The heat collection effect in a very cold environment, it is good, even if the temperature is extremely low
There is always hot water
The high-efficiency three-tube pipe has higher absorption rate and significantly increases heat gain
●Adopts new interference coating process, better than ordinary gradient films
The heat collection performance of vacuum tubes
● The emission rate is reduced by 30-40% and the heat gain is increased.
12% higher, higher water temperature, more hot water
● When the sun is not prLooks good, there is still hot water available
Under the same lighting, more hot water than usual. The tube can produce more hot water with higher water temperature and can still work normally in hot and cold environments. produce hot water at minus 30 degrees as usual
water!
Purple gold tube
Further improved based on the three-tube tube. The film layer contains a variety of rare metal substances with diffuse reflection to ensure the rapid absorption of solar energy. The inner layer of silver and titanium metal plating
The film layer doubles the conversion of geothermal energy, and the thermal efficiency increases rapidly to a temperature close to the boiling point. At the same time, the inner layer vacuum. The process and special coating wrap heat energy tightly, making it difficult
To dissipate.
The violet gold tube adopts PEPAC multi-target interference film technology and adds violet gold coating under the same conditions, it heats up more than 12% faster than ordinary three-dimensional tubes. Faster. When using
The new coating materials and production processes have maximized the three technical parameters of heating, heat collection and service life. The solar absorption rate of the purple gold tube is 0.97.
11 percentage points higher than the national industry standard. The heat collection technology is close to the theoretical limit of vacuum tube heat collection performance, reflecting the highest level of the local solar power industry!

To the naked eye, ordinary tubes and the appearance of the three-tube tube are dark blue, and the appearance of the purple gold tube is dark black (seen without sunlight)
When seenfrom the inside of the tube under the sunlight, the ordinary tube is bluish, the three-tube is reddish, and the purple gold tube is dark blue. The tube is very red.
The tube appears purple gold. like gold when exposed to the sun. It looks red inside (the mix of red and gold is very beautiful and hard to describe. Actually it looks red from the outside
But it looks to gold, I I say it's gold, but it looks like red, I'm dizzy, I can't describe it anyway.)
The Ordinary tubes look like this
It's very beautiful. , is not it ? It's used to deceive people.
Three senior executives
It looks pretty good, but not necessarily taller than me
Zijin Guan
I still like this one
Three senior managers
Looks pretty good, but not necessarily taller than me
Zijin Guan
I still like this one

Those qThose who are rich can use three-pipe tubes, and those who are richer can find Zijin tubes to avoid running out of water in winter
Those who have a little money can still use ordinary tubes
Most solar Most water heater users have more than 20 pipes
There are also those who have less than 20 pipes, but I have since those with more than 20 pipes are usually ordinary pipes.
After all, the price here is too high. There are not many rich people in Guangzhou who are so full that they can spend thousands of dollars to buy more than 20 purple pipes. gold tubes
They don't understand that no matter how many ordinary tubes they install, they will only get ice in winter,
Come to think of it, it seems to be one. A water heater is not necessary to install cold water in winter.
Overall
There aree very many ordinary tubes
There are very few, very few three-tube tubes
Violet gold tubes are even fewer, therefore expensive
p>
Let me tell you, a purple gold coin costs 80 yuan (don't tell me when you buy it, it's as beautiful as I said. It's about this price .The actual selling price in various places is difficult to tell
Just double it for reference)
Also, it is better to use l. stainless steel for the support. Although it can be 500 to 1,000 times more expensive (compared to colored steel), it will not rust or break easily if used. it is placed on the roof. If you don't plan to use it for too long, you can also use galvanized steel (it's a little worse than colored steel, the most commonly used steel is colored steel, which is recommended by traders as a good colored steel.t). It will be fine for two or three years.
