Kostrzewa heat pumps

Air/water monobloc 2 series

Kostrzewa (PPH Kostrzewa sp.k.) is a family-owned Polish maker of pellet boilers based in Giżycko, founded in 1978. It started developing heat pumps in 2020 and names itself as their manufacturer. The range consists of R290 air-to-water monoblocs of its own patented design with a stainless-steel tower casing: the on/off HPR 400, 500 and 600 Deluxe with the HB 1 or HB 2 hydrobox, and the new inverter HPRi 510 Deluxe with the HB 4 hydrobox. Kostrzewa sells no hot water heat pumps.

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.

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.
