Carrier heat pumps

Air/water monobloc 2 series

Carrier is the heating and cooling brand of the US group Carrier Global Corporation, which also owns Viessmann Climate Solutions and Riello. In Germany the residential Carrier brochures are issued by Viessmann Deutschland (Allendorf/Eder). The residential range is two R290 air-to-water monoblock lines: AquaSnap 30AWH-P (4 to 14 kW, flow temperature up to 75 °C, built in Europe) and AquaSnap AWH-NG/NGA (4 to 16 kW, outdoor unit with a wall-hung or all-in-one indoor unit with a 190 l tank). Carrier's other heat pumps (AquaSnap 61AQ, 30RQ and 30WG chillers and heat pumps, 30XWH, VRF) are commercial units.

Carrier Air-to-water monoblock

The whole refrigerant circuit sits in one outdoor unit; only water pipes run into the house. The most common choice for retrofits, because no refrigerant lines need to be installed inside.

Heating output is the figure in the manufacturer's datasheet; the basis (nominal output at A7/W35 or B0/W35, or design heat load) differs between brands, so check the datasheet before comparing. * = design heat load Pdesignh at 35 °C from the BAFA portal.

Sources

Specifications come from the manufacturer's datasheets linked above, grant status from the official lists below, checked November 2, 2026:

SG Ready is a label of the Bundesverband Wärmepumpe (BWP) e.V.; “Yes” means the manufacturer documents the two-input interface or declares it on the BAFA portal, not that the series carries the BWP label – the label list is at waermepumpe.de. EEBUS is a standard of the EEBus Initiative e.V.; Modbus is a registered trademark of Schneider Electric, licensed to the Modbus Organization. Product names, logos and photos belong to their manufacturers and are shown to identify the products. Grant data: BAFA Wärmeerzeuger-Portal and Lista ZUM (IOŚ-PIB) as of the dates shown; the SCOP at 55 °C in the BAFA tables is calculated by Zerofy from the portal's ηs value.
