Naples households can switch on heating from 15 November under the ordinary seasonal calendar, according to Il Mattino and the Comune di Napoli. The ordinary season runs through 31 March, subject to statutory exceptions.
Naples is in climate zone C, with ordinary use limited to a maximum of 10 hours per day, according to Il Mattino. The Comune di Napoli says heating systems are covered by energy-efficiency control requirements, including requirements for qualifying systems above the stated power thresholds.
The average household heating expenditure is estimated at €645 under the tariff assumptions considered, according to the Facile.it estimate cited by Il Mattino. The figure is approximately 25% higher than the previous year at the same consumption level.
The €645 figure is an estimate based on selected fixed-price free-market offers, not a bill that applies to every household. Actual spending varies according to dwelling size, system efficiency, thermostat settings, consumption and the energy tariff.
ENEA considers 19°C generally adequate for indoor comfort and reports potential fuel savings of 5–10% for each degree of reduction. It recommends regular maintenance, keeping radiators unobstructed, limiting ventilation to brief periods, screening windows at night and using thermostatic valves.
ENEA states that thermostatic valves can reduce consumption by up to 20%. Energy-efficiency interventions can reduce heating costs by up to 40%, depending on the intervention. The available sources do not establish the exact annual saving a specific Naples household would obtain from each measure.
