WORKING PRINCIPLE
Non-pressure system is based on the natural circulation-thermosiphon phenomenon. It is the most economical type of solar systems for hot water application. Depending on the different density between hot water and cold water, a water flowing cycle is created in the tube. Hot water flows automatically upwards while the cold water flows down. The water in the storage tank will be heated from this natural circulation.
It has the feature as the most economic type. It can work independently as well as work together with controller. Electric heater can be installed when it is rainy or cloudy day.
