Calmar Pannan V33 is a Swedish-made boiler, designed in accordance with European environmental requirements. All heating surfaces are made of 5 mm structural steel.
Three-stage combustion for optimal heating result and minimal environmental effect:
  1. The logs are vaporized on the ceramic rost in the fire place, from where the exhaust gas is led down to the convection section.
  2. By means of the secondary air the exhaust gas will reach a nearly complete combustion in the convection section, where the exhaust gas temperature is 900-1000 °C.
  3. The exhaust gas will then pass through six water-cooled tubes in the rear smoke chamber. The exhaust temperature is 220-230 °C when leaving the boiler.
