Product Description

High efficiency Solar Hot Water Heater for Home, Hotel, School, and Factory Supply.

The 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 ready for immediate use with fresh water quality. The hot water pressure is derived from the municipal cold water pressure, ensuring a stable temperature without sudden fluctuations.

Key Features:

Maintenance: The tank end cover uses a flange connection, allowing for easy opening and maintenance at any time.
Modular Design: Expandable water tank capacity to meet high consumption needs.
Rapid Exchange: Stainless steel bellows heat exchanger turns cold water into hot water in just 20 seconds.
Versatility: Can be combined with electric heaters, gas boilers, or air source heat pumps as a pre-heating system.

Frequently Asked Questions

How does the pump-free system work?

The system uses natural thermal circulation for heat storage and municipal water pressure for delivery, eliminating the need for an external booster pump.

Is the water quality safe for kitchen use?

Yes. Because the system uses a rapid heat exchange coil, the hot water is never stagnant in the tank, ensuring fresh, pollution-free water.

Can this system operate in extremely cold weather?

Yes, the vacuum tubes and insulation are designed to withstand outdoor temperatures as low as -40ºC.

Can I connect this to my existing gas or electric heater?

Absolutely. It is designed to work seamlessly as a pre-heating equipment for conventional electric, gas, or heat pump systems.

What maintenance is required?

Maintenance is minimal. The flange connection design allows for easy access to the tank interior for cleaning or inspection when necessary.

How quickly does the water heat up?

Our 20-second rapid heat exchange technology ensures that cold water turning into hot water happens almost instantly as it flows through the exchanger.
