Comfortable heating and cooling with the Vaillant aroTHERM heat pump

This kit is a comprehensive heating solution, combining high efficiency, savings and user comfort. The Vaillant aroTHERM split VWL 125/5AS air-to-water heat pump is an ideal choice for both new and modernized buildings. The system utilizes energy from the air, offering significant savings in heating and cooling costs, as well as reducing emissions of harmful substances. The kit includes all the necessary components for smooth operation – the heat pump itself, a wall module, a domestic hot water tank and a controller, ensuring precise control over the system.

The split technology allows for flexible installation – the outdoor unit can be placed on the wall or on the ground, and the indoor unit takes up little space. This makes the aroTHERM heat pump fit perfectly into the building's architecture. The system is quiet in operation, which is particularly important in densely populated areas.

Technical specifications and application

The VWL 125/5AS heat pump is characterized by a heating power of 11.9 kW (at a temperature of 7/35°C). It uses R410A refrigerant, which is commonly used in such devices. Liquid lines with a diameter of 3/8 inches and gas lines with a diameter of 5/8 inches ensure optimal refrigerant flow. The kit is designed for central heating and domestic hot water preparation. Thanks to the ability to control room temperature and remote control, the system offers full control over thermal comfort in the building. The VIH RW 400/3BR tank allows for storing 375 liters of domestic hot water, providing comfort even with higher water consumption.
