ALL-AROUND RAINPROOF
The FDG-PM180SAW water heater has been carefully designed to provide excellent rainproof performance, enabling it to work stably in a variety of outdoor environments. Even in stormy or wet climates, the rainproof enclosure effectively protects the internal components and ensures the long-term operation of the unit without being affected by the weather.
This protective design allows you to enjoy a reliable and continuous supply of hot water without worrying about the effects of inclement weather on the unit’s performance, providing your family with a worry-free hot water experience.

OXYGEN-FREE COPPER TANK
The water heater utilizes a high-quality copper tank as the main heat exchange material, and the excellent thermal conductivity of copper ensures efficient heat transfer. Compared with traditional materials, the copper tank can heat the water flow faster and more evenly, thus improving the overall combustion efficiency of the water heater.
The use of copper tanks also effectively reduces heat loss, allowing every drop of hot water to reach the ideal temperature, providing users with a more comfortable and efficient hot water experience.

MICRO FLAME COMBUSTION TECHNOLOGY
The FDG-PM180SAW is equipped with advanced micro flame combustion technology, which makes the combustion process smoother by precisely controlling the size and stability of the flame. The miniature flame not only effectively improves the combustion efficiency but also reduces the fluctuation of hot water temperature.
The application of this technology allows the water heater to provide continuous hot water while maintaining a stable water temperature, providing users with a more even and comfortable hot water experience.

BUILT-IN GAS PRESSURE STABILIZER
The water heater has a built-in high-performance gas pressure stabilizer that monitors and adjusts the gas flow in real-time to ensure that the water heater maintains a stable water temperature under various conditions of use.
By automatically adjusting the gas pressure, fluctuations in water temperature due to changes in air pressure are avoided, allowing for consistent hot water temperatures every time the water heater is used. This design not only enhances the comfort of hot water use but also effectively extends the service life of the equipment.
