AroTHERM heat pump basic system VWL-155/2 Vaillant

AroTHERM air-water heat pump is the perfect solution as a renewable system both for the new building and for the renovation of an existing installation. It provides heating, cooling and DHW service, maximizing efficiency and guaranteeing maximum comfort. The inverter technology ensures that the energy production is adapted to the demand of the installation and guarantees a long duration of the system. In addition, compact air-water heat pump systems are exempt from meeting the annual maintenance requirements established in the Fluorinated Gas Regulations, since they are characterized by being hermetic. Another advantage is that there are no refrigerants to handle during installation, which means that the installer does not need a refrigerator certificate.

Lower noise emissions
The sound level of aroTHERM is only 44 dB (A) at a distance of 3 m from the building, or even below 30 dB (A) in silent mode. By choosing the installation site well, there is no problem in installing aroTHERM in densely populated areas.

Long useful life
aroTHERM is energy efficient and meets the requirements of the new construction and comfort of the future NZEB today. The aroTHERM system with uniTOWER provides planning security, as the system can be installed easily and quickly in one day with two operators. This minimizes installation costs.

The perfect complement: the uniTOWER hydraulic tower:
The uniTOWER compact hydraulic tower contains a 190 l DHW tank - perfect for newly designed single-family homes with medium DHW needs. aroTHERM in combination with uniTOWER provides you with the necessary ACS performance. As an alternative to uniTOWER, the monobloc can be combined with a separate DHW tank with a capacity of 150 to 500 liters. For solar DHW support, use the 500-liter auroSTOR SW, available in the "plus" and "exclusive" lines. For larger systems we recommend the allSTOR exclusive multifunction tank.
