Low presure solar water heater
1. Working pricinple:
Â
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.
