Sun Energy Solar Water Heater non-pressure type(300L)

Product Description

solar water heater

Working pricinples

1 .This solar water heater also relies on the natural circulation of water between the collector and the tank (that is tubes absorb solar energy,and heats the water inside the tube,hot water rises,cold water flows down)

2 . It differs from compact non-pressurized solar water heater, because it has a copper coil inside the inner tank. The hot water rises from the tube into the tank, and heats the copper coil and finaly heats the water inside the copper coil . Therefore the water tank is just as a heat storage tank.

3 .So the hot water we use is actually from the copper coil, it is more clean,and even drinkable(as the copper can purify the water.).The whole system also works at 0.3MPA

advantages

1 .A copper coil is installed inside the tank as the heat exchanger

2 .when water flows into the copper coil,it absorbs heat from the water in the tank,therefore,the water tank is just a heat stotage.

Feature:

1 .It can withstand pressure of tap water when it works, and copper coil in tank bear pressure.

2 .Storage tank is used to heat water floeing through copper coil, water absorbers much heat when flowing through the copper coil, hot water is available immediately when you need.

3 .High quality SUS304-2B stainless steel for water tank, processed by argon arc welding technique, under strict quality control system, tank will never rust and leak.

4 .High borosilic all glass vacuum tube has selective absorbing surface, absorptivity above 0.93 and emissivity below 0.05, it enables vacuum tubes to have good absorb and transmit performance.

5 .Relevant accessories are optional instead of compulsory, client can choose some or none according to actual need.

6 .Its indirect solar system, so water quality is superior, much cleaner than direct solar system.

7 .Life duration:15 years, warranty 5 years.
