Our vertical air source heat pump series features an upright, compact cabinet that occupies just 0.8 m² of floor space. The top‑discharge fan optimizes airflow while minimizing debris intake. Despite the small footprint, these units deliver full-rated capacity with DC inverter compressors and low‑noise fans (<38 dB). Maintenance access is front‑facing, simplifying filter changes and refrigerant checks. Vertical air source heat pump models suit apartments, rooftop units, and mechanical closets where space is limited but heating demands remain high.
