Aermec heat pumps

Air/water monobloc 4 series

Aermec is an Italian HVAC manufacturer from Bevilacqua near Verona, founded in 1961 by Giordano Riello and the main company of the family-owned Giordano Riello International Group. Most of its output is commercial (chillers, large heat pumps, fan coils, air handling units); the residential air-to-water range is the R32 HMI family, sold as HMI, HMI_1 (4 to 16 kW, single or three phase) and the three-phase HMI T units for 18 to 30 kW. In Germany the heat pumps are listed under Aermec Deutschland GmbH.

Aermec 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.

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.
