The data relating to the production of hot water were measured with the setting of the hot water temperature at 55°C,
with the cold water inlet temperature at 15°C and with the boiler at maximum power.
* The fire and rated power as well as the efficiency are measured in a lab test in optimal installation conditions.
** The data was recorded in a lab test in optimal conditions. Hourly consumption can vary according to the type of
pellets used and the installation.
*** The heatable volume is subject to variation according to installation conditions, type of house insulation and
external climatic conditions connected with the geographic location.
N.B.: The fuel humidity must not exceed 25%.
