Protherm Condensing Boilers – Older Versions with Tank Connection Option
In this category you will find the older, but still available and serviced generation of Protherm condensing boilers from the Lev and Panther Condens (model KKO) ranges, with the option to connect an external domestic hot water tank. These are proven boilers, suitable especially for households that need to combine heating with their own DHW tank, or for replacing an existing older boiler of the same generation. The Lev 28 KKO and Panther Condens (12, 25 and 30 KKO) boilers are still on sale and fully supported by both the manufacturer and our service.
