💡 Product Description
Solar Hot Water Heater

Our pump-free household solar water heater features an open water tank for heat storage and a closed coil for heat exchange. Utilizing 20-second rapid heat exchange technology, hot water is available quickly while maintaining fresh water quality.

Constant Pressure: Hot water pressure is derived from the municipal cold water pressure, ensuring consistent temperature and flow.
Maintenance Friendly: The tank uses flange connections, allowing it to be opened and maintained easily at any time.
Modular Design: Expandable water tanks to meet higher consumption needs.
High Efficiency: Cold water flows through stainless steel bellows, heating up in just 20 seconds.

Frequently Asked Questions
How does the 20-second rapid heat exchange work?
Cold water flows through high-efficiency stainless steel bellows inside the tank. The stored thermal energy is transferred instantly to the flowing water, providing hot water almost immediately.
Can the system operate in freezing climates?
Yes, the system is designed to withstand extreme outdoor temperatures as low as -40ºC, making it suitable for cold regions.
Is a booster pump required for hot water pressure?
No, this is a pump-free system. The hot water pressure is directly powered by your municipal cold water pressure, ensuring a strong and steady flow.
What is the advantage of the open tank with flange connection?
The flange connection allows the tank to be opened for cleaning and maintenance at any time, extending the lifespan of the equipment and ensuring water hygiene.
Can I use this with my existing gas or electric heater?
Absolutely. This solar heater can act as a pre-heating system and can be seamlessly combined with gas boilers, electric heaters, or air source heat pumps.
Is the water safe for kitchen use?
Yes, because the water for use is exchanged through a closed stainless steel coil, it does not mix with the stored water, ensuring the water remains fresh and pollution-free.
