Do I need to add water or fluid first for wall mounted solar?

Add the liquid first. It is not possible to add water to the wall-mounted solar water heater before adding liquid. A medium liquid should be added. Before moving in, the wall-mounted solar power is not filled because it will evaporate a lot and damage the machine if not used for a long time. When turned on, water cannot be filled directly. Wall-mounted solar water heaters are specially designed and developed for large and small buildings, making up for the regret that traditional solar water heaters cannot integrate perfectly with buildings and the environment due to defects inherent.

< p>1. In the north, antifreeze is ethylene glycol (propylene glycol or glycerol) antifreeze. Heat exchange fluids with different freezing points are selected based on different latitudes. 2. In areas south of the Yangtze River, it is appropriate to useUse antifreeze that does not freeze at -10°C. 3. In areas north of the Yangtze River, antifreeze that does not freeze at -20°C should be used. 4. In areas north of the Yellow River, use antifreeze that does not freeze at -30°C. Make sure the system does not freeze in winter. 5. In Yunnan and elsewhere, pure water is also used as a heat transfer fluid.
