PHNIX in Zerofy

Zerofy integration

Zerofy reads PHNIX heat pumps through the manufacturer's cloud (PHNIX Cloud), with the account the heat pump is already registered with. Autopilot then moves heat into the building and the hot water tank when your own solar power is available or the electricity price is low.

PHNIX 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.

PHNIX Hot water heat pumps

A small heat pump built onto a hot water tank. It heats drinking water only and is a good way to turn surplus solar into stored heat – or to add hot water to a house that is otherwise heated differently.

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.
