Midea heat pumps

Air/water monoblocAir/water split 7 series

Midea is a Chinese appliance and air-conditioning group headquartered in Beijiao (Foshan), founded in 1968; in Germany its heat pumps are sold and registered by Midea Europe GmbH in Eschborn. The current residential range consists of R290 air-to-water monoblocs: M thermal Arctic (4 to 16 kW), M thermal Nature (8 to 16 kW, up to 80 °C) and the larger Mars series (26 to 40 kW), plus the H-Pack, an indoor-installed unit without an outdoor part. The earlier R32 generation (M thermal split with hydro box and R32 monoblocs) is still on the grant lists.

Midea in Zerofy

Zerofy has no integration for Midea yet. Where a series below has an SG Ready input, Zerofy can still switch it through a Shelly relay. The heat pump comparison lists every brand Zerofy supports.

Midea 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.

Midea Air-to-water split

An outdoor unit plus an indoor hydraulic station, joined by refrigerant lines. The pipework inside the house stays frost-free without glycol, and the indoor part is often quieter to place.

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.
