The so-called non pressurized solar hot water geyser system is friendly environmental. It is really simple and safe to get the heat from solar energy.
Our non pressurized solar hot water geyser system operates depending on gravity and can not withstand pressure. The water is heated by the solar vacuum tubes, and the hot water flows up and the cold water flows down, thus forming a circulation loop. This non pressurized solar hot water geyser system does not require pumps or controllers for proper operation, which makes it very reliable. The open circuit means that even water being boiling does not increase the pressure inside the tank. Thanks to this, this system is trouble-free and safe.
