Standard boilers

Luna3

Heating only and combi - fanned and open flue
READ MORE

The high-performance range of Luna3 gas boilers is appropriate for large spaces with associated high levels of DHW demand.

Ideal in detached houses with multi-zone systems, being able to control multiple temperature deliveries for maximum comfort. Two simultaneous heating temperature ranges: 30/85°C for radiators systems, and/or 30/45°C for floor heating systems.

A simple interface with large LCD display provides comprehensive information and setting options, including weekly scheduling in addition to advanced self-diagnostics.

The brass hydroblock ensures long term reliable performance.

Characteristics
  • Brass hydroblock with flowmeter with turbine (combi models)
  • Steel burner
  • Enhanced primary exchanger made of copper pipes protected with anticorrosion coating 
  • Enhanced stainless steel DHW heat exchanger
  • Low energy circulating pump with automatic air vent
  • Overheat limit thermostat for the water/flue exchanger
  • Hydraulic pressure switch to prevent boiler’s operating in event of low water
  • AFR system, patented by Baxi, that allows the efficiency optimization thanks to a perfect inlet air regulation (fanned flue models with dual flue system)
