Charging Boilers

Optima Komfort Plus

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 charging zone increases stability and efficiency of boiler operation.

4 lata gwarancji na szczelność wymiennika ciepła, 2 lata na pozostałe elementy i sprawne działanie kotła 4 years of warranty for heat exchanger tightness, 2 years for the remaining components and efficient operation of boiler
wymiennik ciepła wykonany z atestowanej stali kotłowej /gat. P265GH/ o grubości 6mm heat exchanger made of certified boiler steel /grade P265GH/ of 6 mm thickness
