It can steadily meet households’ long-term demand for reliable heating and consistent hot water supply.
Core Advantages
Dual Heat Exchanger Structure for Steady & Comfortable Water Temperature By adopting a separated dual heat exchanger design, the heating and domestic hot water systems operate independently without mutual interference. The high-quality stainless steel plate heat exchanger ensures high heat exchange efficiency and excellent thermal conductivity, maintaining stable and uniform hot water temperature. It effectively eliminates temperature fluctuations and provides an improved bathing experience.
High-Grade Materials for Extended Service Life The stainless steel burner features outstanding heat resistance, corrosion resistance and anti-aging performance, ensuring even and stable flame combustion and prolonging the overall service life of the appliance. All core components are produced under strict quality standards to guarantee dependable long-term operation.
Comprehensive Functions & Stable Operation Built with anti-electromagnetic interference performance, it maintains stable working status in complex household power environments and avoids operational failures caused by signal interference. The circulation pump anti-lock function ensures smooth startup even after long-term shutdown and prevents pump seizing, greatly enhancing the overall stability of the boiler.
