I. Solar Hot Water Project Solution of Single Heater Serial or Parallel Connected + Waterline Control Box
Working Principle: The cold water goes into the solar heat collectors via the waterline control box, and then is heated by the heat that is transformed by the evacuated tubes from light. The user will know the temperature of the hot water through the temperature sensors and indicators in the tank. When the water becomes hot enough for shower, the user can open the tap and use the hot water. In cloudy and rainy days, the water in the tank can be heated by the electric heaters.
Features: Simple structure, suitable for small-scale users who don’t have a high demand on the quantity and quality of hot water.
II. Solar Hot Water Project Solution of Joint Tubes Serial or Parallel Connected + Waterline Control Box + Storage Tank
Working Principle: The cold water goes into the solar heat collectors via the waterline control box, and then is heated by the heat that is transformed by the evacuated tubes from light. The hot water will be stored in the storage tank. There is auxiliary automatic electric heater in the storage tank. When the temperature in the storage tank is higher than the fixed temperature, the electric heat will remain off; when the temperature in the storage tank is lower than the fixed temperature, the electric heater will be started to heat the water to the fixed temperature. At the fixed temperature, the electric heater will stop working. This system can work in all the four seasons of the year and in all weather conditions.
Features: Reliable system, suitable for large-scale users who have a high demand on the quantity and quality of hot water.
