Maintenance is free of charge.

The structure is uncomplicated and does not contain glycol. There is no need for annual or periodic check-ups or maintenance. The heat pipe is designed with a blind sleeve to prevent pollution and leaks, making installation easy. The vacuum tubes do not contain water, so if one tube breaks, it will not affect the overall system’s performance.

Exceptional Performance

Utilizing advanced vacuum-tube technology, more than 92% of solar energy is efficiently converted into thermal energy for heating without any loss during circulation. The system features a thicker insulation layer, enabling it to function effectively even in winter and in extreme temperatures as low as minus 30 degrees.

Reliable Operation

The system operates simply by utilizing city net water without the need for pumps. The inner tank is constructed from 1.2mm thick stainless steel (SUS316-1.2mm). It operates under high pressure and is directly connected to the running water supply, functioning automatically. Equipped with a T/P valve and exhaust valve, it safeguards the tank from shrinkage.

Year-round Functionality

Designed and installed to operate in all seasons, the system incorporates freezing-proof technology. Optionally, an electric heater can be used to ensure an ample supply of hot water on rainy days.


The vacuum tubes are directly connected to the tank, resulting in minimal heat loss. The blind sleeve design and SUS316 inner tank make it suitable for areas with low-quality water supply. Additionally, an aluminum alloy frame is available as an option. The installation angle can be set at either 30 or 45 degrees, and the pipe location on the tank is flexible. This system is more affordable than a split pressurized system.
