Combi Boiler

Smart-HV &
Nano-PK

The choice is yours
Energy efficiency class: A+

  • Perfect heating with logs and pellets
  • Extremely compact overall system
  • Smart-Touch-Display
  • Automated pellet supply system

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.

  • Unique comfort
  • Minimise fuel costs and be able to react to market price
  • Highest controllability and maximum efficiency
  • Fuel supply security for the future
  • Two seperate, efficient heat exchanger systems for just one chimney
  • Fully automatic fuel detection and switchover
  • Individual installation possibilities
  • Perfect price-to-performance ratio
  • Energy efficiency class: A+
