Smart renovation with combi boilers

Find your right heating system with Hargassner!

Ecological energy such as heat from pellets or wood logs remains the first choice for many when it comes to sustainable heating refurbishment.
But which combined heating system is right for you?

The expertise of Hargassner Heiztechnik, your pioneer for biomass, will guide you as a builder, renovator or planner competently on the way to the right climate-neutral biomass heating. The heating with wood in various combinations is very much in vogue. Every renovation project has its own requirements (size, insulation, existing chimney, etc.). Hargassner has the right advice and the right products for you.

We will also be happy to inform you about dismantling the old (oil) heating system, disposing of the tank or calculating the dimensions.

Practical 2-in-1 solutions

Would you like to heat mainly with pellets and only occasionally switch to wood logs?

Then the Hargassner Smart-HV & Nano-PK combination boiler is ideal for you! The duo of the Hargassner wood log heating system Smart-HV 17-23 kW and the pellet boiler Nano-PK 6-15 kW or the “big brother” Nano-PK 20-23 kW is perfect for renovators and combines two highly efficient heat exchangers and targeted heat distribution with minimal heat loss and maximum efficiency. The perfect combination of comfort and crisis-proof heating!

Hargassner offers a further four different combi variants as an option. They can thus be optimally adapted to the customer’s needs. Whether an inexpensive entry-level model or convenient with a large filling chamber and automatic filling with pellets.

Smart duo as a small space miracle

A particularly practical combination heating system: the newly introduced and particularly compact Smart-Duo 17-30 kW combination boiler. It requires only 0.90 m² of space. This saves space in both old and new buildings.

The advantages of the tried-and-tested Hargassner Smart-HV log boiler and the Nano-PK pellet boiler are thus combined in a single appliance. This also applies to the control of the buffer, boiler and two heat circuits. The flue pipe connection height of 50 cm is ideal for renovators. The fully ready-to-use delivery enables quick installation.

Other advantages:

  • Optimised 2-zone fireclay combustion chamber for pellets and logs
  • Filling with pellets is automatic
  • Sophisticated combustion technology
  • modern appearance
  • simple control unit via smart touch display
  • automatic boiler cleaning device for both fuels

Anton Hofer - Product Manager | Hargassner

“The whole thing is designed to be so compact that it is also interesting for the standard detached house or even a holiday home. This product will appeal to many people who are unsettled by the energy crisis, the eco-transition and the turbulent development of fossil fuels.”

Anton Hofer | Product Manager Hargassner Ges mbH

Smoke-free and clean

For wood logs, the Smart-Duo offers an optimum filling chamber size for half-metre logs, filling chamber lighting as standard and – a particularly important issue for end customers – smoke-free reheating thanks to carbonisation gas extraction. Primary and secondary air control is automatic, as is ignition (via the pellet combustion chamber). Like the other Hargassner biomass boilers, the Smart-Duo guarantees clean combustion and highest efficiency.
