Kostrzewa

What Kostrzewa does

Kostrzewa (legal entity PPH Kostrzewa sp. k.) is a family-owned Polish manufacturer of biomass heating systems headquartered in Giżycko, Poland, founded in 1978 by Tadeusz Kazimierz Kostrzewa. The company designs, manufactures, and sells automatic pellet boilers (8-330 kW), high-temperature air-to-water heat pumps (HPR Deluxe with R290 refrigerant), electric boilers (ELE series, 2-24 kW), and pellet burners (Platinum Bio VG and Spin). Its technical differentiation rests on patented variable geometry (VG) burner technology (Patent No. 228615), the OMS operating monitoring system (Patent No. 235699), and the HPR Deluxe heat pump (Patent No. 72619). Production is conducted at a single facility in Giżycko supported by an in-house R&D laboratory operational since 2014.

The business operates a distributor-led go-to-market model exclusively, selling through local partners in Poland and 19-21 European countries with 200+ authorized service technicians delivering post-warranty support. Revenue is generated through one-time hardware sales of boilers (PLN 13,400-38,500), heat pumps (PLN 25,830-33,210), burners (PLN 7,000-13,900), and accessories, supplemented by service contracts and an online spare parts shop. Approximately 80,000 pellet boilers have been produced cumulatively, heating ~350,000 people, alongside 1,000+ industrial-scale projects up to 300 kW. Customer segments span residential homeowners (primary), agricultural facilities, and industrial/commercial buildings. Products are listed on Poland's ZUM register for the Czyste Powietrze government subsidy program and certified to Ecodesign 2020 and PN-EN 303-5:2021 Class 5 standards.

Ownership is concentrated 100% in the founding family (Tadeusz, Barbara, Paweł, and Monika Kostrzewa) with no external equity investors; financing has come from EU operational and R&D grants totaling over PLN 15 million across multiple programs. The company employs approximately 180 people and has pursued a measured expansion path through product line extension (heat pumps, electric boilers), geographic buildout across Central and Eastern Europe, and a factory expansion completed between 2019 and 2021.
