Sinclair in Zerofy

Zerofy has no integration for Sinclair 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.

Sinclair 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.

Sinclair 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.

Sinclair 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 4, 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.
