Outdated Product
$855.48 up to $926.90
High-performance Italian double-circuit gas boiler of the third generation with a turbocharged (closed) combustion chamber. It features relatively small dimensions, low noise level and efficient microprocessor control system. The manufacturer is positioning itself as a product of the middle price category, intended for organizing heating and hot water supply of a large city apartment or a detached house up to 232 m². High heat output (31 kW) provides up to 18 L/min of hot water up to 65 °C (when heating water from the initial temperature of 25 °C). The design of the BAXI LUNA-3 310 Fi boiler is optimized for operation in two modes of operation of the heating circuit. In the first mode, a coolant with a temperature of up to 85 °C is circulated through the system with conventional wall-mount...ed radiators, and the second mode is intended for underfloor heating systems, especially for which the maximum coolant temperature is limited to 45 °C. A microprocessor control circuit and a modulated burner with flame ionization control allow automation to quickly change the thermal power of the device, preventing gas overruns. Advanced engineering solutions provide high efficiency (93.1%) and significantly reduce the overall installation and maintenance costs of the heating/hot water supply system. The boiler is equipped with a complete set of security systems and safety devices.
