Herz Minifire 6-18 kW

HERZ – premium Austrian heating technology. The manufacturer also developed log wood and automatic biomass systems.

Minifire – compact, manually loaded wood-fired boiler. According to the original data plate shown, it is a unit manufactured in 2000. It can be designed for a central heating system based on the use of own firewood.

• Minifire type on the original plate: the specific old unit has been identified.
• Log wood firing: can be used with manual fuel loading, does not include pellet feeding.
• 6–18 kW indicated for wood firing: the data plate marks this with the designation "max. Beheizungsleistung"; we do not claim this to be a verified useful heat output range.
• 3 bar maximum permissible operating pressure: the verified limit data for the heating system design.
• 95 °C maximum permissible operating temperature: safety and control fittings must be adapted to the specific boiler.

Documentation and controls: the old control panel visible in the photo requires a precise model-year manual. The found 2004 HERZ newsletter describes a later BioControl 3000 control system; we do not claim this to be the existing equipment of the 2000 machine. The exact 2000 Minifire user manual is not yet available.

New price – check: 2026.10.06. For the exact 2000 Minifire version, no verified current new price was found in the requested three webshops. Custom quote required, specifying currency, VAT content, regulation, hydraulics, and installation separately. The historical price of a later Minifire Standard or De Luxe is not the current new price of the offered machine.
