Non Pressure Water Heater Working Principle

The vacuum tube absorbs the sun’s rays and turns it into heat energy, heating the water in the 

tubes. As the temperature of the water rises it becomes less dense, so the hot water in the tubes

 float into the tank, and the cold water in the tank travels down into the tubes. This natural cycle

 keeps repeating and the water in the tank gets hot. This unit will work below freezing 

temperatures as the glass tubes are sealed and heat can only enter and not escape from them. 

Non pressure system drains by gravity, unit must be placed at high place above supply line

Non Pressure System Advantages:

1. Lowest cost per gallon to heat water

2. Can operate in freezing temperatures; glass tubes are vacuum sealed. Due to special coating 

   on tube heat is only able to enter and not escape.

3. Tank is insulated to keep hot water for days

4. Less components and faster install time

5. Small tank mixes cold water gradually to larger tank

8,we could product for customer'special need

It has 15years long life span ,and the vacuum tubes can work individually,

so if the only one of them can't work,it won't influence on the others.

The spare parts can be changed freely .it is suitable for the many resident

buildings.
