A+++ Efficiency at 35°C & 55°C

To adapt to local climate conditions, the compressor of the Ultra-Silent Series is precisely optimized. Combined with:

• High-efficiency DC inverter fan

• Fin-and-tube heat exchanger with optimized refrigerant flow paths

• CFD-designed air duct system

the Ultra-Silent Series achieves ErP A+++ energy efficiency at both 35°C and 55°C, based on EN 14825 / EN 14511, representing a leading performance level in the heat pump industry.

With a SCOP exceeding 5.1 (A7/W35), the system maintains high efficiency throughout the entire heating season.

In 2025, the Ultra-Silent Series was successfully certified by AIT (Austrian Institute of Technology), a national-level laboratory, further reinforcing performance credibility and market confidence.

High Performance in Extreme Conditions

The Ultra-Silent Series delivers stable heating performance even at –25°C ambient temperature, ensuring reliable comfort in cold-climate regions.

• Maximum water outlet temperature: up to 75°C

• Suitable for both new installations and renovation projects

• Designed with a strong focus on efficiency, durability, and long-term reliability

  
  

• Core Noise Reduction Technology

• Despite its strong performance, the Ultra-Silent Series achieves ultra-low operating noise levels, reaching as low as 35 dB(A) under optimized conditions.

• Advanced acoustic design, vibration isolation, and airflow optimization ensure quiet and unobtrusive operation, making it ideal for residential environments.
