Air/water heat pump WAB series

propane (R290)hot waterlow-temperature

Overview
The Weishaupt Aeroblock® WAB air-to-water heat pump uses outdoor air energy for space heating and domestic hot water (DHW) production. Monobloc design groups all components into a single outdoor unit. Standard supply includes cooling function. Direct connection to heating circuit and DHW systems.

Key points

• High energy efficiency: from 1 kW of electricity the unit delivers between 4 and 5 kW of thermal energy.
• Modulating capacity: the unit adapts to the thermal demand to avoid full-load cycling, improving efficiency and reducing noise.
• Low-temperature operation: operable down to −22 °C outdoor temperature.
• Natural refrigerant: R290 (propane) with GWP ≈ 0.02.
• Maximum supply temperature: 70 °C (enables DHW comfort and renovation of existing buildings).
• Cooling function: can be used for cooling (underfloor cooling or fan coil units depending on variant).
• Acoustic comfort: optimized compressors and fans, vibration dampers and modulation mode reduce noise emissions.
• Complete solution possible: integration with Weishaupt multifunction storage (WKS) including hydraulic connections and control.
• Materials and quality: aluminium, stainless steel and premium coatings for durability.
