DHW Heat Pump Air-to-WateraroSTOR VWL B 80-150l

Compact wall-hung hot water heat pump – powered by renewable energy.

Convincingly efficient, delightfully quiet
Hot water comfort for small families
Compact design, quick installation

Whether you’re modernising your home, building a new one, or living in an apartment, the aroSTOR hot water heat pump lets you harness renewable energy from the air for an eco-friendly and efficient hot water supply. Quiet and highly efficient, it transforms 1 kWh of electricity into more than 3 kWh of heat energy for water heating. When combined with a photovoltaic system for self-generated electricity, you can further reduce both your carbon footprint and your energy costs. Compact, wall-mounted, and featuring a durable stainless steel tank, the aroSTOR meets the needs of families of two to four people — providing reliable comfort while saving space and energy.
