Lengths are available in different specifications. If the specifications are the same, the length and thickness will be the same. If the specifications are different, the length and thickness will be different.
The only difference between 18 tubes and 20 tubes is the number of tubes. The capacity of 18 tube water tank is relatively smaller, generally around 150 liters, and can be used by 3 tubes. 5 people. The choice should be based on the size of the family and the amount of water consumed.
How many liters do the 18 tubes of a solar water heater hold?
In total, 18 tubes can store 239 L of water.
A total of 478 kilograms, but generally solar water can only be released from the water tank, and the vacuum tube water cannot be released. The net weight of a general solar water heater tank is about 20kg. Calculated based on a water capacity of 150 kg,the total weight of the tank is approximately 170 kg depending on the water capacity.
47 thin tubes and 18 branches are approximately 110 liters, and 58 tubes and 18 branches are 135/140/145/150/170. Different manufacturers produce different water tank diameters and vacuum tube hole spacing. i.e. the diameter of the water tank. The diameter and height are different, so the water capacity is not necessarily the same.
Solar water heater is a 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. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the domestic market share. Water heatersHousehold vacuum tube heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum heat collecting tubes which use the principle of hot water floating. and cold water flows to cause microcirculation in the water.
