Operating Principle 

A non-powered solar water heating system operates under pressure. It is a solar water heater that integrates solar heat collection, heat storage, and heat exchange.
The system works as follows: vacuum tubes absorb sunlight and convert it into heat energy to warm the water in the water tank. Municipal tap water directly undergoes heat exchange through a single-flow channel/double-flow channel inside the water tank. 

Operational Principles

Both non-powered solar systems and conventional solar water heaters employ vacuum tubes to harness solar energy, utilizing natural circulation to heat water in the storage tank. Neither requires electrical power, relying entirely on solar radiation for heating. The core distinctions lie in their operational mechanisms:
Passive Solar Systems: Function under pressure by allowing municipal tap water to pass through stainless steel pipes inside the tank, where it undergoes secondary heat exchange with the stored hot water. (Note: These systems require access to municipal water supply and are not suitable for areas without it.)
Conventional Solar Water Heaters: The non-pressurized system depends on gravitational water
level differences for water supply, leading to relatively low outlet pressure.
Energy Consumption
‌Passive Solar Systems: Zero energy consumption, completely electricity-free. Features include resistance to tube explosion, freeze tolerance, and minimal energy loss.
Conventional Solar Water Heaters: Require electrically driven circulation pumps and booster pumps, resulting in higher energy consumption.
Water Quality Assurance
‌ Passive Solar Systems: Adopt closed-loop stainless steel 304/316 channel heat exchange with pressurized water outlet, ensuring clean water without secondary pollution.
Conventional Solar Water Heaters: Water stored in the tank for prolonged periods is prone to limescale buildup and other quality issues.
Water Pressure Stability
‌Passive Solar Systems: Operate under constant pressure via municipal water supply, ensuring consistent and sufficient hot water pressure.
Conventional Solar Water Heaters: Non-pressurized tanks lead to unstable water pressure and poor user experience due to low outlet pressure.
Installation Scenarios
Passive Solar Systems support series-parallel connection of multiple modules to meet diverse water demand. Compared to conventional systems, they save on pipes, valves, and pumps, reducing installation costs. Additionally, they eliminate the risk of tube explosion for safer and more comfortable hot water use.
