The benefits at a glance: • Low-emission combustion burner (oil- or gas-fired) and optimized combustion chamber geometry. • Extremely economical and environmentally friendly through modulating boiler water temperature; the boiler switches off completely when no heat is required. • Reliable heat transfer due to wide water jackets and large water content. • Highly effective boiler insulation for negligible standby losses. • Easy installation and start-up: all Viessmann burners are factory tested and adjusted to the rated output.
