Anonymous users2024-01-24That's the brand that a friend of mine uses, and he said it's pretty good, and it's enough for a family of three.
Not recommended for you, I'll just say my experience.
My friend's house has one that he puts in the position under the plastic steel window outside the balcony window. >>>More
The price in each region is different, and it also depends on what the capacity is, so it is recommended to consult local agents or manufacturers.
In fact, the two main differences lie in the later use, in terms of heat collection efficiency, the vacuum tube must be higher than the flat plate, but in terms of endurance and overall aesthetics, the superiority of the flat plate is shown! And flat panel solar installation and maintenance are also relatively convenient!
There are a lot of accessories, screws, nuts. Pipes, insulation cotton, brackets, etc.
Because the working fluid in the plate collector is a low-temperature resistant liquid, it can be kept at minus 40 degrees without freezing, so there is no accuracy, generally at 110 degrees.
