1. 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.
