Stainless Stainless Vacuum Tube Solar Water With Small Tank

1. Working pricinple:

Low pressure solar water heater with assistant tank is scientifically designed and it is very popular in the international market. The cold water can flow through the assistant tank and fill into the main tank. When it main tank of our solar water heater is full, the floating ball in the assistant tank rises and the water channel is blocked, thus the water feeding process is stopped. If the hot water in the main tank is used, the water level will descend, and the floating ball drops down, thus the water channel is open again, and the cold water will flow into the heat automatically. In this way, the circulation is formed and the hot water will be supplied continuously.

6.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
