Cast-iron energy-efficient fireplace Optim 7

Code: Optim-7

Cast-iron energy-efficient fireplace opening door Optim 7

The whole cast iron fireplace inserts in modern design of hearth lined with accumulation material Carcon (ceramic refractory concrete), and printed glass. All models are characterized by perfect conbustion and high efficiency. Matter of course is the external combustion air income. The newly developed system of controled triple combustion (CTC) allowed to adjust the effciency of cast iron fireplaces to 79% and in the same time achieve slow and clean combustion.

  • Whole cast iron fireplace insert, hearth with special accumulating material - long, clean burning and fuel saving External air income
  • Depth adjustable frame
  • IFT – special frame and door profile for directing and leading air, double glass possible
  • Deep hearth with aerodynamic barrier for more comfortable service, control and high quality combustion
  • Stand integrated
