Pressurized Solar Water Heaters:

1. System with 1.5mm 316L stainlesss or SUS-304 stainless steel, closed-loop system, with stand Max.1.2Mpa
2.The storage tank is pressurized, meaning it can hold water under pressure, similar to a conventional water heater.
3.Pressurized systems are generally more efficient and suitable for use in areas with cold climates or where water pressure is inconsistent.
4.There are 316L marine grade stainless steel sleeve inside the water tank work as heat exchanger between HEAT PIPE vacuum tube and water tank
5.They tend to be more expensive and complex to install due to the additional components required.

Non-Pressurized Solar Water Heaters:

1.Also known as “passive” or “compact” systems, non-pressurized solar water heaters rely on natural convection to circulate water.
2.These systems don’t have a pump and rely on gravity to move water between the solar collectors and the storage tank.
3.The storage tank is open to atmospheric pressure, and water flows into it as it heats up in the collector and becomes less dense.
4.Non-pressurized systems are simpler and more cost-effective, making them suitable for regions with consistent sunlight and moderate climates.
5.They may not be as efficient as pressurized systems, particularly in colder climates, and may require additional insulation to prevent heat loss.

Choosing between pressured and non-pressurized solar water heaters depends on factors like climate, water quality, available space, and budget. Pressurized systems are generally more versatile and efficient but come with higher installation costs, while non-pressurized systems are simpler and more affordable but may be less suitable for certain conditions.
