Boiler Defro Optima Komfort Plus 20 kW
Structure of OPTIMA KOMFORT PLUS boilers ensures two-system operation and combustion of all types of fuels - fines in case of firing from top (with operation time up to 20 hours) and the remaining solid fuels (coal, wood, mix of coal and fines) in case of firing from bottom. Electronic control of air blowing for combustion, allowing more precise temperature adjustment and increasing servicing comfort, are used in the boilers. Multi-point air supply system to the fuel charing zone increases stability and efficiency of boiler operation.
- mix of coal and fine coal,
- wood in pieces,
- edgings and chips.
- 4 years for tightness of the boiler's exchanger.
- 2 years for other elements.
