Standard boilers
Luna3
Heating only and combi - fanned and open flue
READ MOREThe 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.
