Protherm Lev and Panther Condens KKV – Older Versions of Flow-Through Boilers
This category contains an older generation of Protherm condensing boilers with flow-through hot water heating (KKV) – specifically the Lev and Panther Condens lines. These are combi boilers that both heat and prepare DHW directly without needing a storage tank. Panther Condens is also available in a set with the Thermolink P controller for more comfortable heating control. These models are suitable especially for replacing an existing installation of the same generation, or if you are looking for a proven boiler at a lower price.
