The FEDERICA BUGATTI indirect boiler is made of stainless steel, water-jacketed tank. The efficiency of heat exchange is maintained for the entire service life of the boiler due to the special finned tank. FEDERICA BUGATTI INOX ensures quick water heating and proportionate mixing of hot water with the heated water in the boiler. The internal coating of the tank is made entirely of "food grade" AISI 304 chrome-nickel steel. We confirm the high quality of our products with a five-year warranty.
