About Kokoszka-Lotz

Kokoszka - Lotz is a Polish family company specializing in the production of heating devices, mainly accumulative fireplaces, water inserts and kitchens.

The company's beginnings date back to 1995, when the fireplace industry was only just entering the Polish market. Our expertise in the production of fireplace inserts is based on our long-term design and construction activities, supported by over a thousand completed jobs. Over 20 years of experience, together with domestic market observation, have highlighted the need to introduce products with high heating parameters, which would be affordable for the Polish consumer.

From our passion and many years of experience, confirmed by numerous certificates and testimonies of our knowledge, we have developed devices with an unique construction - series of Certus, Verus and kitchen furnaces with accumulative capabilities and high heating efficiency.

Having in mind the good and needs of the customer, our company constantly improves its offer, focusing on safety, quality and innovation of its products. The company's goal is to meet the individual expectations of domestic and foreign market customers, as well as to build flexible and lasting business relations with commerce and construction companies.

Environmental care is crucial for us, therefore for many years the motto of the company has been "Heat in harmony with nature", which applies not only to our products, their production process, but also takes into account good regional heating traditions and a lifestyle which is close to nature. The materials used to manufacture the furnaces are fully recyclable and their construction allows total and complete combustion of the fuel, guaranteeing low emissions, low fuel consumption and a clean environment around it.

The products offered by our company are entirely manufactured in Poland and, as a Polish product, are taking into account the specificity and needs of domestic customers. We want our brand to be the most popular choice of customers, and our products to meet all customer expectations.

Kind regards,

Lidia and Jarosław Kokoszka
