* All the data are based on the appliance fuelled with EN 14961-2 standard type-approved pellets.
** Important: take into consideration the fact that the heatable volume is greatly influenced by the insulation of the house,
i.e. the energy class of the building and by the position of the appliance in the planimetry of the house. The indicated
values, therefore, can vary considerably.
*** The value does not take into account the electricity consumption of the circulating pump, as it depends on the
pressure loss in the plumbing system.
