Product Q&A

Q:How does the solar water heater work?

It adopts simple thermal circulation where cold water is heated by solar vacuum tubes, and hot water rises to the tank while cold water flows down, creating a natural thermosyphon effect.

Q:What is the warranty period?

We provide a 5-year warranty for this solar water heater.

Q:What materials are used for the tank?

The inner tank is made of 0.41mm SUS304-2B food grade stainless steel (with optional SUS316L), and the outer tank is 0.41mm SUS304-2B stainless steel.

Q:Does the system require a pump?

No, the system uses a simple structure where the solar collector and water tank are connected directly, requiring no pump to push fluid.

Q:What is the maximum capacity?

The maximum capacity of this solar water heater is 300L.
