The 70s
From a small workshop to European markets
The history of Kostrzewa starts with the manufacturing of simple central heating boilers in a workshop and ends with an automated factory of equipment that has gained great popularity on European markets.
In 1978 Tadeusz Kazimierz Kostrzewa established a Locksmith Workshop and Boiler Factory in Spytkowo near Giżycko, where he made boilers, domestic hot water exchangers and blowers for agricultural purposes. For the first six months of activity, the founder designed prototypes of his machines. After that he hired his first employer. The production amounted to about 150 boilers per year.
Decades of hard work finally bore fruit
The company would not exist were it not for the construction talent and inventiveness of Tadeusz Kazimierz Kostrzewa. It took years to form a team of specialists highly engaged in development. Tadeusz Kazimierz Kostrzewa was also greatly supported by his wife, Barbara (who handled the company's accounting and finances from the very beginning), his son Paweł with his wife (research and development department, web sales development, service department) and numerous other specialists. Thanks to their joint work, the company is now very dynamically entering its fifth decade of activity.
The 80s
Production mechanisation
During the time of the People's Republic of Poland, private entrepreneurs were treated by the government as an "unwanted element". Launching mass production under those circumstances was almost impossible, because state enterprises always had priority buying production machinery and materials. Achieving the specified production quota was just as difficult. Tadeusz Kostrzewa learned it the hard way. This is why all devices were made manually at first.
The purchase of first machines - guillotine and press brakes - was a breakthrough for the company, allowing to launch mass production of boilers with power range between 11 and 300 kW. Employment increased.
50 boilers per month
After the cessation of the martial law in the early 80s, the company's seat was moved to Giżycko. There, Tadeusz Kostrzewa built an impressive workshop which allowed him to modernise and intensify production. The company was able to make fifty small or ten large boilers per month.
In the late 80s, the company greatly suffered from hyperinflation. All earned money had to be immediately invested, because its value dropped by the hour.
The 90s
Democracy brought new life to craft
The period of democratic transformations finally gave craftsmen hope for development. After the fall of the communist regime, private businesses started competing with state enterprises under free market principles. Anyone who had the means could now acquire all required production tools. Thanks to the equipment purchased in the 90s the company earned enough money to build a modern machine park and new, larger headquarters, where it is based to this day.
The secret of the lit flue
From the very beginning Kostrzewa's priority was to systematically improve his products.
"You can tell that fuel is inefficiently burned in a boiler room if you see dark smoke rising from the chimney", says the company's founder. "This was unacceptable in my boilers, and the flue did not shine in the dark. In 1993 I invented a solution which was implemented by other companies only much later. For upper combustion boilers, I installed an additional air intake in the back, which allowed for the ignition of gases entering the upper part of the boiler. Other manufacturers placed the air intake in front, which did not yield the desired effect. My solution turned out to be a huge success."
The strategy of prioritising product improvement and production development remains effective to this day
2000-
The first Polish pellet boiler
Poland's EU accession was a true breakthrough. Thanks to the received funding, Polish economy accelerated visibly, and Kostrzewa started competing with western manufacturers.
Even before the EU accession, the company caught wind in its sails. All thanks to Paweł, son of Barbara and Tadeusz, who became deeply engaged in its development. In 2000 Kostrzewa, as the first company in Poland, introduced pellet boilers for heating single family homes. Four years later it launched Pellets Plus, a boiler with automatic fuel ignition function. Among other models, the Mini Bio (2009) became the company's flagship and bestseller - highly reliable, low on emissions, and very cost effective.
Vilnius as the window to European markets
A family business operating on the local market turned into a full enterprise with multiple departments: research and development, construction, technical, customer service, marketing, domestic and foreign sales, as well as its own laboratory.
It expanded thanks to the Internet and the company's first branch established in Vilnius with the help of Paweł Kostrzewa's friend from university days - Dariusz Pleskaczewski. Thanks to the engagement of Dariusz and his partner, Robert Stasilowicz, Kostrzewa is currently the most recognisable pellet boiler brand in Lithuania.
2010-
Kostrzewa's warmth for thousands of families
In the period between 2000 and 2017 Kostrzewa has made over 60 thousand pellet heating devices for single family homes, which means that they keep 300 thousand people warm. The company participated in 1000 large projects involving boilers with power up to 300 kW.
This motivates Kostrzewa to redouble its efforts and seek even better solutions, such as boilers with the innovative Platinum Bio VG variable geometry burner, adjusting the device's power to the current heat demand.
We are working on new ways to heat
In 2014 the company launched its own modern research laboratory. The research facility allows to test the designed devices for important parameters (efficiency, emissions, power consumption etc.) before they are delivered to our Clients. KOSTRZEWA's laboratory also works with several research facilities in Poland.
Practically maintenance free and cost effective, safe and low on emissions - all for the client's comfort and satisfaction. These are not promises, these are facts. They are guaranteed by, among other things, the meeting of the strict requirements of the so-called EU Ecodesign, confirmed by certified of accredited external laboratories. Certificates are important, but satisfied clients are even more important.
KOSTRZEWA has production and storage buildings with the total area of 15 140 m².
Currently, the factory of clean heat biomass devices is being significantly expanded.
At the same time, new technologies for producing heat from renewable energy are being developed.
