Outdated Product
$827.16 up to $900.37
Performant Italian double-circuit gas boiler with a closed combustion chamber. Designed for wall mounting, it is characterized by relatively compact dimensions, low noise level and an efficient microprocessor control system. It is positioned as a product of the middle price category, intended for organizing heating and hot water supply of a country house, cottage, large city apartment, office or household premises up to 210 m². The high net heat output of 28 kW ensures a decent hot water capacity, delivering up to 16 L/min when the water is heated from a starting temperature of 25°C. The design of the BAXI LUNA-3 280 Fi boiler is optimized for operation in two modes of operation of the heating circuit. In the first case, the coolant is heated to a maximum temperature of 85 °C and gives off...heat through conventional wall-mounted radiators. The second is designed to work with underfloor heating systems, while the water temperature does not exceed 45 °C. An efficient electronic control circuit and a modulated burner with flame ionization control allow automation to quickly change the heat output, preventing gas overruns. Progressive engineering solutions provide a high efficiency of 93% and significantly reduce the overall cost of organizing / maintaining the system.
