Powerful 13 kW heating output for large projects
The Viessmann AWO-E-AC 151.A13 represents a powerful solution for apartment buildings, commercial properties, and demanding residential projects. With a nominal heating output of 8.1 kW at A7/W35 conditions and a maximum output of up to 13.4 kW, it reliably covers even the highest heating requirements.
Outstanding efficiency values in the high-performance class
Despite its high output, the Viessmann AWO-E-AC 151.A13 achieves an excellent COP value of 4.9 at A7/W35 conditions. The seasonal coefficient of performance (SCOP) of 4.52 for low-temperature applications and the A+++ energy efficiency rating demonstrate the unit's economical operation. Even at extreme outside temperatures of -7°C, 11.1 kW of heating output is still provided.
Optimized dual fan concept
The robust outdoor unit of the Viessmann AWO-E-AC 151.A13 features an optimized dual fan system that ensures a high air flow rate of 4188 m³/h. The two EC fans operate at controlled speed and automatically adapt to operating conditions, maximizing efficiency and minimizing noise.
Extended power modulation for flexibility
The inverter-controlled double-roller compressor of the Viessmann AWO-E-AC 151.A13 offers a wide modulation range from 3.0 to 13.4 kW. This flexibility enables precise adaptation to different load profiles and operating conditions. The stepless control reduces cycle losses and significantly optimizes annual energy consumption.
Professional system integration
The Viessmann AWO-E-AC 151.A13 is designed for integration into complex heating systems. The fully equipped indoor unit with a 16-liter buffer tank, 8 kW instantaneous heating water heater, and intelligent control system forms the heart of the system.
