Product Q&A

Q:How does the copper coil heat exchanger work?

Cold water in the vacuum tube is heated by sunshine and circulates to the tank. The hot water in the tank then transfers heat to the water inside the copper coil, allowing users to draw fresh hot water directly from the coil.

Q:Is the hot water fresh and safe?

Yes, the hot water inside the copper coil is fresh without secondary pollution, making it suitable for use as portable water.

Q:Can this system handle mains pressure?

Yes, the system is designed to accept mains pressure cold water, and the copper coil can take pressure and connect directly to tap water.

Q:What materials are used for the tank?

The outer tank is made of SUS304-2B/316L stainless steel or powder-coated color steel. The inner tank is made of 0.5mm thick SUS304/316L food-grade stainless steel.

Q:What is the warranty period for this product?

We provide a 5-year warranty for this pre-heated solar geyser.
