Sauter heat pumps
Hot water 2 series
Sauter is a French brand of electric heating, water heaters and ventilation that belongs to the family-owned Groupe Atlantic (La Roche-sur-Yon); it is sold by Société Commerciale Groupe Atlantic (SCGA), the same company that sells Thermor. Not to be confused with the Swiss building-automation company Sauter (sauter.fr). Sauter's only heat pumps for heating water are two hot water heat pumps made by Groupe Atlantic in France: the R290 Saturnia (200 and 270 l, room or ducted air) and the Takhini (200 and 250 l, room air), whose published figures are identical to Thermor's Aéromax Access. Its other heat pumps are air-to-air air conditioners. Both water heaters connect to the group's Cozytouch app.

Zerofy has no integration for Sauter 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.
Sauter heat pump types
Sauter 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.

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.
