Standard boilers

Heating only and combi - fanned and open flue

Residential

Wall Hung

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.
