Tradition and Innovation in Building Technology
Fellner GmbH is a family-run building technology company headquartered in Lübeck with a branch in Dunkelsdorf. Founded in 1968 by Kurt Fellner as a gas and water installation and plumbing business, it has developed into a modern service company in the HVAC and plumbing sector. Its core competencies include heating technology (heat pumps, wood heating systems, gas condensing boilers), plumbing installation including bathroom planning, solar thermal, and biomass heating systems such as wood gasification and pellet systems. The company supports projects from consulting and individual planning through professional execution to service and maintenance. Customers are private households and businesses in the Lübeck region and the Baltic Sea region. Since 2024, John and Edward Fellner have led the company in the second generation; installation of battery storage systems, commissioning and grid connection of solar systems are carried out by an external electrical contractor.
