304 Stainless Steel Low Pressure Solar Water Heater System

 

1. Working pricinple:

 

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 wan work indepently as well as work together with controller. Electric heater can be installed when it is rainy or claudy day.

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
