Description
The Vaillant aroSTOR VWL BM 270/5 is a compact hot water heat pump with 265 l storage volume and an integrated additional heat exchanger. It efficiently uses ambient air for hot water preparation, can intelligently cooperate with a PV system, and is ideally suited for operation in modern, energy-conscious buildings thanks to SG-Ready. Due to the refrigerant R290 (very low global warming potential) and energy efficiency class A for hot water preparation, the system is designed for economical, future-proof operation.
