A+++ High Efficiency Gas Combi Boiler
Designed and produced by China Baedin, a specialized manufacturer of wall-mounted heating boilers, the A+++ High Efficiency Gas Combi Boiler adopts an optimized dual heat exchanger system. Fitted with a stainless steel plate heat exchanger and precision three-way valve control, it realizes fully separated operation of heating and domestic hot water loops for efficient heat transfer and stable outlet temperature. Supported by gas proportional control, high-sensitivity NTC temperature management, full-range safety protection, a stainless steel burner and premium core parts, it runs steadily with great durability and wide applicability, serving as the top choice for whole-house heating and constant-temperature hot water supply.
The A+++ high efficiency gas combi boiler offers six power options: 20KW, 24KW, 28KW, 32KW, 36KW and 40KW. It can be reasonably configured according to the heating area and hot water consumption of different house types, satisfying most daily household heating and water needs.
Application Scenarios
Integrating efficient space heating and constant domestic hot water supply, the A+++ high efficiency gas combi boiler is applicable to apartments, large homes, villas and other residential buildings. It maintains stable performance under different installation environments, climate conditions and frequent daily operation. With accurate temperature control, high heat exchange efficiency, quiet and steady operation, and complete safety functions, it is also equipped with anti-electromagnetic interference and circulation pump anti-seize protection. It can continuously meet families’ long-term needs for reliable heating and steady hot water.
Core Strengths
Separate Dual Heat Exchanger for Consistent & Comfortable Water Temperature
Thanks to an independent dual heat exchanger structure, the heating and hot water systems work individually without cross-influence. The high-efficiency stainless steel plate heat exchanger delivers outstanding thermal conductivity, stabilizes water temperature effectively, reduces temperature swings, and greatly improves bathing comfort.
High-Grade Construction for Extended Durability
The stainless steel burner features outstanding heat and corrosion resistance with good anti-aging performance, ensuring even and stable combustion and prolonging the service life of the whole unit. All key components are produced under strict quality control to ensure reliable long-hour operation.
Complete Functions & Improved Operating Stability
With anti-electromagnetic interference design, the boiler stays stable in complex household power conditions and reduces failures caused by external signal interference. The circulation pump anti-lock function ensures easy start-up even after long-term non-use and avoids pump blockage, significantly enhancing the stability of the whole system.
