Working pricinple:
Non pressure solar water heater whose full name is directly inserting type full glass vaccum tube solar water heater,can't bear pressure due to the O-ring seal between vaccum tube and water tank. It is the most economical type of solar systems for hot water application.This solar water heater should be used in the non pressure situation, and it relies on the natural circulation of water between the tube and the tank. There are inlet/outlet pipe and overflow pipe under the tank. If the tank is filled with water,the water will flow through the overflow pipe and warming messege is sent, also, the water feeding valve needs to be turned off. When using this product, the hot water will flow through the inlet/outlet pipe because of the gravity effect, and at this time, the overflow pipe is mainly used to supply air. There is water in the vaccum tube, thus the water inthe tank will spill out under the condition that one tube is broken. In addition, electric heater can be installed to guarantee the hot water supply when it is rainy or cloudy.
