The 90L solar water heater is made of 10 glass tubes.
1. Under normal circumstances, ordinary solar water heaters are one and eight meters large tubes. long. There are 20 vacuum tubes, the water tank capacity is about 180 liters net capacity, the price is about 2800, 24 tube type, the water tank capacity is about 220 liters net capacity, the price is around 3500, For 30 tube type, the water tank capacity is around 270 liters. Net capacity, the price is about 4200. The total capacity is calculated approximately by the product of the number of vacuum tubes by 11. Under normal circumstances, we calculate based on the total capacity. Although this method is not very practical, it is beneficial for sales based on the area calculation, 5 large tubes are approximately one square meter.
2. I don't know if you are north or southsouth. Try to buy bigger ones in the north. In the south, around 16 or 18 is good. The further north, the better. Otherwise, it won't be very useful in winter. If that doesn't work, you can add an electric heater.
Water temperature depends on conditions. If there is little water on a sunny day, it often exceeds 90 degrees. Not necessarily if you use a lot of water. Because after use, the temperature of the cold water will drop. The sun will warm up a little. If it's cloudy and there's no sun at all, it won't heat up.
3. As far as I know, solar water heaters can usually hold 20 tubes. They convert solar energy into thermal energy, thereby reducing harmful gas emissions. It is a new type of renewable energy and the source of much of the energy on earth. However, the biggest disadvantage of solar water heaters is that its are strongly affected by the external environment, such as: directly affected by day and night, season, climate, geographical environment and geographical location, and cannot be used 24 hours a day.
I hope the editor's response can be helpful to you!
How many liters does a solar water heater cost?
6 kWh. The water volume of 20 solar tubes is 200 liters. To raise 200 liters of water by 10 degrees requires 1.5 degrees of electricity. The normal water temperature is 20 degrees. It must therefore be heated to 60 degrees. you have to heat it to 40 degrees for heating, which consumes 6 degrees of electricity. Solar energy refers to the energy of thermal radiation from the sun (see the three modes of propagation of thermal energy: radiation). Its main manifestation is often called solar rays.
Capacity of 12 tube solar water heater
1. The liters neckrants of water heaters are: 10 liters, 11 liters, 13 liters, 16 liters. , 20 liters, 24 liters and other liters. Ordinary families often buy 10 liters, 11 liters, 13 liters and 16 liters.
2. 11 liters: suitable for situations where the kitchen and bathroom are not far from each other, less than five meters, and there is only one bathroom.
3. 10 liters: suitable for apartments where the kitchen and bathroom are separated by a wall and there is only one bathroom.
4. 16 liters: suitable for situations where there are two bathrooms and the distance between the bathroom and the kitchen is relatively large.
5.13 liters: suitable for situations where the kitchen and bathroom are far from each other. Or if there are two bathrooms and the distance between the bathroom and the kitchen is not particularly large, it will not affect whether one of the bathrooms has a bathtub.ire.
120 liters. According to the query on Yiyi Decoration Network, 1 tube is 10 liters and 12 is 120 liters, so the capacity of the 12 tube solar water heater is 120 liters. Solar water heater is a heating device that converts solar energy into thermal energy, heating water from low temperature to high temperature to meet people's use of hot water in life and production .
