You are talking about insulation pipes. Domestic pipes generally use inner diameters of 16mm, 20mm and 25mm. Insulation pipes are generally selected based on the thickness of the pipes. , and 40 mm, ranging from 50 mm. In order to prevent freezing in the north, "heating tape" must be installed on the pipes inside the insulating pipes, so there is a certain danger. Nowadays, many solar cells have the function of draining pipes (for example, Jindian Juneng Solar), which eliminates the need for insulating pipes and heating tapes.
Solar energy can- Can it be used in Shandong in winter when temperatures are around minus 10 degrees Celsius? What will the water temperature be that day?
It is best to visit old users, they have the most say. I recommend the "Jindian Juneng Solar", which has an aluminum coating.food grade 304-2B stainless steel. Solar water can be drunk with confidence. The price is moderate, around 1000-3000 yuan for home use. It comes with a one-year warranty, a ten-year repair warranty and a thirty-year warranty (due to different designs, the lifespan of solar generally does not vary) . exceed 15 years). It is suitable for any difficult environment and has good management skills. The road drain function is particularly suitable for users who experience freezing conditions outdoors in winter. There's usually no water in the pipes, and of course there isn't. afraid of frozen pipes. You don't have to worry about solar problems and troubles if you have no one at home for several days (travel, visiting relatives, etc.). mechanical automatic function, very convenient to use (all solar energy canbe installed automatically with a computer). If you can't buy this brand where you are, visit past users to see which solar power brand in your area is best). in winter. It is important to understand the problem of frozen pipelines. Most solar energy pipes are attached with heating tapes and then insulated. If the pipes are frozen, they can be heated with heating tapes to thaw them. This method can also be used, but it carries some risks. defrost the pipes in time, otherwise the pipes will freeze and crack.
I come from Yantai, Shandong. I use "Jindian Juneng Solar Energy". The pipes have a drainage function and no auxiliary electric heating device. is used. I have been taking baths at home for a month (about 3 days). Wash once), the water temperature is between 60-70℃. The water temperature has increased over the last few years.last few days and is expected to reach 80°C within the year.
