Questione giuridica chiave
Whether the installation of a speckstone stove instead of a fireplace qualifies as an energy-saving measure deductible for tax purposes.
Decisione estratta
No. Replacing the fireplace while keeping the heat pump in operation was not a measure of rational energy use within the applicable ordinance.
Motivazione estratta
The measure was not listed among deductible energy-saving installations, and the evidence did not show a comparable energy-balance improvement; the existing heat pump remained the main heating system.
