Non-pressurized compact solar water heater is a kind of solar water heating system that solar collector and storage water tank are connected together, water tank on the top and collector panel on the bottom. It relies on the natural circulation of waters between the collector and the water tank. As water in the vacuum tubes is heated, it rises naturally into the tank, while cool water in the tank flows down to the bottom of the vacuum tubes, causing circulation throughout the system. It moves household water or a heat-transfer fluid through the system without pumps. It is a simple and safe solution to get heat power from the sun.
Features:
☆ Cheap and reliable solution, Simple structure, Easy installation
☆ High efficiency
☆ Withstands water pressure no more than 0.1MPa
☆ Operated without any power supplying
☆ Electric heater can be used 1500W or 3000W
☆ Hot water can be used directly, or can be used as a pre-heat
Typical installation configuration:
Here is the simplest of installation configurations for the classic solar water heaters. The tank is low pressure, open vent. The tank is manually filled by opening a tap in the house. Once the tank is full, water runs out through an overflow pipe which is fed back down into the house. As using water, the tank gradually drains until it is empty. Users can fill it up at the appropriate time according to how much the water left.
