Product Description

Integrated solar heating factory supplied pump-free high quality solar hot water system.

High-Efficiency Solar Hot Water System

This pump-free household solar water heater utilizes an open water tank for heat storage and a closed coil for heat exchange. With 20-second rapid heat exchange technology, hot water is ready quickly while maintaining fresh water quality. The hot water pressure is derived from municipal cold water pressure, ensuring a stable temperature without sudden fluctuations.

1
The end cover of the solar water tank adopts a flange connection, allowing it to be opened and maintained at any time for safety and convenience.
2
The system adopts a modular design; the water tank can be expanded to meet high water consumption requirements.
3
Rapid heat exchange technology: cold water flows through the stainless steel bellows for 20 seconds to instantly convert to hot water.

Frequently Asked Questions
How long does the heat exchange process take?

The system features rapid heat exchange technology that converts cold water into hot water in just 20 seconds as it flows through the stainless steel bellows.

Is the water pressure sufficient for a good shower experience?

Yes, the hot water pressure comes directly from the municipal cold water pressure, providing a surging and sufficient volume for a comfortable experience.

What materials are used for the inner tank?

The inner tank is constructed from high-quality 0.5mm SUS304 stainless steel, ensuring durability and water purity.

Can this system work in extremely cold climates?

Yes, the system is designed to operate in outdoor temperatures as low as -40ºC, making it suitable for a wide range of geographical locations.

Can it be integrated with existing water heaters?

Absolutely. This solar water heater can serve as a pre-heating unit and be combined with electric water heaters, gas boilers, or air source heat pumps.

Is the hot water safe for kitchen use?

Yes, because the system uses a rapid heat exchange through stainless steel coils rather than storing the used water directly in the tank for long periods, the water quality remains fresh and suitable for kitchen use.
