The furnace
The furnace is the heart of the Tigchel heater and the Tigchel finoven. Over the years, the particular shape of the combustion area has developed to become an optimal system able to sustain high temperatures. Also because of dozens of small air nozzles, the wood is entirely used up for generating heat with only a small amount of ash remaining.

 The benefits of this furnace include:

  • All the wood is used for heating
  • Low flue gas emissions
  • Economical in the use of fuel
  • A relatively small amount of combustion air is required
  • Low maintenance
  • Long life
