Comprehensive heating solution from Vaillant – aroTHERM Split VWL 125/5AS

This kit is a complete, high-performance air-to-water split heat pump designed for both new and modernized buildings. The aroTHERM system combines efficient heating, cooling and domestic hot water preparation, offering significant savings and user comfort. Utilizing renewable energy from the air allows for a reduction in operating costs of up to 75% and a decrease in harmful emissions.

The kit consists of an outdoor unit VWL 125/5AS, an indoor unit VWL 127/5IS, a hot water tank VIH RW 300/3BR, a buffer tank VPS R 100/1M and an advanced sensoCOMFORT 720 controller. The whole system ensures reliable and efficient operation of the heating system for many years.

Technology and performance

The aroTHERM Split heat pump is characterized by quiet operation, which is particularly important in densely populated areas. Quick and easy installation – the units can be located up to 25 meters apart – translates to lower installation costs. The system is characterized by high efficiency, and its components work together in an optimized manner. Heating power at 11.9 kW at a temperature of 7/35°C ensures thermal comfort even on colder days. A COP of 5.8 (for Tj = +7°C) confirms the high energy efficiency of the device.

Thanks to the use of R410A refrigerant, the system ensures reliable operation in various climatic conditions. Additionally, the active cooling function allows for comfortable maintenance of the optimal temperature inside the premises during heat waves.

User comfort and control

The sensoCOMFORT 720 controller allows for precise control of the heating system and adaptation to the individual needs of users. The ability to remote control increases convenience and allows you to monitor the system's operation from anywhere. Compatibility with other Vaillant devices allows you to create a comprehensive heating system that will meet the expectations of even the most demanding customers. The system is also ready to cooperate with photovoltaic installations and heat recovery ventilation systems, which further increases its energy efficiency.
