We invite you to visit the KOSTRZEWA booth at this year's ISH 2025 trade fair in Frankfurt am Main – the most important event for the HVAC and heating industry in Europe!

The innovative system controls the amount of fuel and ash in boilers. Until now, users had to remember to refill fuel and clean the ash pan. KOSTRZEWA's OMS system, which is available in our equipment, informs the user in advance about planned activities, presenting this information on the boiler and room regulator screen. The OMS makes boiler operation convenient, easy and safe, especially for the elderly.

KOSTRZEWA company has 40 years of experience in manufacturing central heating boilers. We were the first company in Poland to manufacture pellet boiler for a single-family house in 2000. For a long time, we were the only company in the country, who “believed” in the pellet. Other manufacturers have quite recently “convinced themselves” to implement such method of heating.
