Hot Sales Low Pressure Solar Water Heater

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.

7. common troubles and shooting methods

Phenomena	Cause Analysis	Methods
Cold water on sunny day	1. There is something above water tank or dense smog or stained 2. The inlet valve fasten incompletely and cold water take the place of hot water in tank	1. Remove the hinder or install another place 2. Change inlet valve
Fail to fill water fully	1. Low pressure of running water 2. Leakage of inlet pipe 3. Leakage of water tank	1. Install a small water pump 2. Change inlet pipe 3. Replace a water tank
Leakage from the tank	1. Broken of seal or water tank installed incorrectly 2.The crack of inner tank	1. Exchange a new seal or adjust the water tank 2. Replace a water tank
Unstable water temperature	Unstable pressure of running water	Adding an assistant tank that can store water, stable the pressure and mix cold water or using a thermostatic valve
Failed to get hot water in winter	1. Frozen of inlet or outlet pipe 2.It's too cold 3. No insulation through pipes	1. Asking for help from supplier 2. When hot water used at night, please let water tank empty and input water next morning 3. Open the heater valve to keep worm at the coldest days
