Cast-iron energy-efficient & thermodynamic fireplace HKD 2.2 TUNNEL

Code: HKD-2.2-Tunnel

Cast-iron energy-efficient & thermodynamic fireplace HKD 2.2 TUNNEL

Cast-iron hearth with cast-iron detachable Φ180 cone. A damper can be fitted to the cone for manual adjustment of the flue gas output flow.

The combustion chamber has Chamotte (compressed fire-resistant brick) lining, with high heat accumulation capacity, and the cone is shielded with isothermic material.

It is possible to create many variants with the two doors available for this hearth (f/d-f/d: straight opening door/straight opening door, r/d-r/d: circular opening door/circular opening door, f/d-f/s: straight opening door/ straight sliding door ("easy lift" mechanism) and reclining door (klick-klack mechanism), f/s-f/s: straight sliding ("easy lift" mechanism) and reclining door (klick-klack mechanism)/ straight sliding ("easy lift" mechanism) and reclining door (klick-klack mechanism). Each door is equipped with ceramic glass (resistant to 800 Cο), and detachable metallic frame that ensures a perfect aesthetic result when installed, depending on its shape (straight or circular).

Manual adjustment of combustion air. Supplied with a metallic adjustable base.

  • Nominal thermal output : 9 kW (average value over three eight-hour periods)

  • Flue gas mass flow : nominal load 10 g/sec        accumulation mode 17 g/sec 
  • Weight : hearth199 kg / chamotte 46 kg
  • Germany: BlmSchV 2.stufe
  • Austria: 15aBVG
  • Switzerland: LRV

Tested according to: EN 13229W, EN 13229WA

  • INOX version
  • "EAS" electronic combustion air adjustment system 
  • "MAS" ceramic rings system for heat accumulation

MAS ceramic ring system for high heat accumulation and release thereof into the room for 3 to 6 hours after the fireplace has been put out (lower temperature of flue gas by approximately 200 ΟC during output).

Water assist system (radiator) that transfers 30% of the produced heat to the water and increases hearth output by approximately 7 kW.
