Air/water heat pump WBB series

hot waterlow-temperatureclass A+++

Overview
The new Biblock® WBB air/water heat pumps combine high performance with low noise levels. They consist of an outdoor unit and an indoor unit and extract energy from the surrounding air. Their design enables ultra-quiet operation, allowing installation at short distances from neighboring buildings.

Main features

• Ultra-quiet operation: example sound pressure level for outdoor unit WBB 12 [A7/W35] = 35 dB(A) at 1.5 m.
• Comprehensive standard equipment: the indoor unit includes deaeration and dirt separation devices, cooling equipment, a flow meter with integrated energy meter and electric backup for space heating and domestic hot water.
• Intuitive control: operation via a colour display with LED status bar; remote control via web browser or smartphone (Weishaupt app).
• Corrosion protection: large 45 m² evaporator heat-exchange surface with BlueFin coating.
• Composite acoustic insulation on the indoor unit for very low noise emission.
• Modulating and reliable operation down to outdoor temperatures of -22 °C.
• DHW comfort: steam injection enabling domestic hot water temperatures up to 65 °C.
• Multifunction cylinder WKS 300/100 LE (heat pump/distribution circuit interface): 300 L domestic hot water cylinder, 100 L buffer, class-A heating circulation pump.
• SG Ready equipped for connection to future smart electrical distribution networks.
