KALDAIA 24/30 MTN
CONDENSING
Wall-mounted boilers:
Thirty years of experience in designing and creating solutions for space heating and domestic hot water have allowed us to create two ranges of high-quality boilers: condensing, both indoor and outdoor, and open-chamber with low NOx emissions. INNOVITA products are designed, tested, and manufactured entirely in our laboratories in Bosisio Parini (LC), thus guaranteeing a high level and quality of Made in Italy.
Features:
• Kaldaia is designed, tested, and entirely produced in our Bosisio Parini factory, thus guaranteeing a high level and quality of Made in Italy
• The primary exchanger is made with a single stainless steel coil with a large internal section to ensure high efficiency and reduced pressure drops; moreover, the coil structure ensures easy maintenance and reduced impurity deposits
• The high-efficiency, low-consumption class A circulator ensures significant electricity savings
• The active combustion control system regulates the gas flow to maintain a constant air/gas ratio, thus achieving reduced gas consumption and continuous monitoring of polluting emissions
• Very quiet
• Modulation up to 1:9
• Kaldaia is equipped with high-performance components
• The layout of Kaldaia allows for quick disassembly of the main components
• Kaldaia is perfect for replacements and offers high performance on new and old generation systems
• Simplified gas conversion: no mechanical operation on the product is required.
User interface:
Equipped with an easy-to-use digital display, Kaldaia is easily managed by the user in a clear and intuitive way. The presence of function-specific keys allows you to adjust the temperatures of the domestic hot water system and the heating system and monitor the operation of the appliance.
