Decide for yourself

You decide whether automated with pellets or manually with logs

Thanks to the perfect combustion technology of both boilers and the arrangement with two separate heat exchangers, the highest system efficiencies are achieved and maximum comfort is attained. If the buffer tank is empty and the wood log boiler Neo-HV (which is the first to be activated) is not in operation, the system switches automatically to the Smart-PK pellet boiler.

This combination consists of the manually fillable, compact Smart-HV log boiler and the Nano-PK pellet boiler with automatic heat exchanger cleaning and innovative and convenient discharge system. The compact and small design is ideal for anyone who mainly heats with pellets and occasionally wants to use logs. This gives you perfect control over your heating costs.
