As autumn temperatures begin to fall, knowing when you can turn on the heating in Italy becomes increasingly important. Whether you live in Rome, Milan or somewhere in the Italian Alps, there are national regulations governing when heating systems can be used, how many hours they can operate each day and the maximum permitted indoor temperature.
The rules apply to both homeowners and tenants and are primarily established by Presidential Decree No. 74 of 16 April 2013 and Presidential Decree No. 412 of 26 August 1993. Italy is divided into six climate zones, each with its own heating season and daily operating limits.
However, the rules can vary depending on the municipality, and there are additional considerations for people living in apartment buildings with shared heating systems.
Here’s everything you need to know about Italy’s heating regulations for the 2026–2027 winter season.
Italy heating rules by climate zone
Italy is divided into six climate zones, from A to F, according to the climatic conditions of each municipality. The classification is based on gradi giorno (degree days), a measure of how much heating a building typically needs throughout the year.
The colder the area, the earlier residents can switch on their heating and the longer they can keep it running.
The national heating calendar for 2026–2027 is as follows:
Zone A – warmest areas
- Cities: Lampedusa, Linosa and Porto Empedocle.
- Heating period: 1 December – 15 March.
- Daily limit: 6 hours.
Zone B
- Cities: Agrigento, Palermo, Catania and Reggio Calabria.
- Heating period: 1 December – 31 March.
- Daily limit: 8 hours.
Zone C
- Cities: Naples, Salerno, Cagliari and Taranto.
- Heating period: 15 November – 31 March.
- Daily limit: 10 hours.
Zone D
- Cities: Rome, Florence, Genoa and Pescara.
- Heating period: 1 November – 15 April.
- Daily limit: 12 hours.
Zone E
- Cities: Milan, Turin, Bologna and Venice.
- Heating period: 15 October – 15 April.
- Daily limit: 14 hours.
Zone F – coldest areas
- Cities: Belluno, Trento and Cuneo.
- Heating period: No restrictions.
- Daily limit: No restrictions.
These are the standard national dates. Individual municipalities can introduce local variations, so it’s always worth checking with your local council before switching on the heating.
What time can you turn on the heating in Italy?
As well as determining the heating season, Italian regulations limit the number of hours heating systems can operate each day.
For climate zones A to E, heating can generally operate between 5am and 11pm, subject to the maximum daily allowance for each zone.
The permitted hours can be distributed throughout the day rather than used in one continuous period. For example, a household in Milan (Zone E) can use its 14 daily hours in several intervals, such as in the morning and evening.
It’s important to remember that these are maximum limits, not minimum requirements. There is no obligation to keep the heating running for the full permitted period.
In Zone F, there are no national restrictions on operating hours.
Centralised vs independent heating: what are the rules?
One important distinction in Italy is whether your property has centralised or independent heating.
This is particularly relevant if you live in an apartment building (condominio).
Centralised heating (riscaldamento centralizzato)
In buildings with centralised heating, a single system supplies heat to several apartments. The operating schedule is generally established by the condominium, which must respect the national and local regulations.
The condominium assembly (assemblea condominiale) can decide how to distribute the permitted heating hours, taking residents’ needs and running costs into account.
For example, the building might operate its heating for a few hours in the morning and again in the evening rather than using all the permitted hours continuously.
The building administrator (amministratore di condominio) is responsible for implementing the agreed schedule and managing the system.
Independent heating (riscaldamento autonomo)
If your property has its own independent heating system, you generally have greater control over when you switch it on and off.
You can manage the heating schedule yourself, provided you stay within the legal heating period and daily operating limits for your municipality.
The distinction is important: condominium schedules apply to residents using the shared heating system, whereas those with independent systems manage their own operating times within the applicable regulations.
Who decides when the heating comes on in a condominium?
For apartment buildings with centralised heating, the condominium assembly is responsible for deciding how the shared system operates, within the limits established by national legislation and local ordinances.
The assembly can agree on the daily operating schedule and make changes through a formal resolution, provided these decisions comply with the applicable regulations.
The building administrator then implements the decisions, including adjusting the heating system’s timers and informing residents of the agreed schedule.
Where no specific decision has been made, the administrator must ensure that the system operates in accordance with the applicable legal requirements.
Residents who are unsure about their building’s heating schedule should contact their condominium administrator.
Can Italian municipalities change the heating dates?
Yes. Although the national heating calendar provides the standard framework, local authorities can introduce changes through municipal ordinances.
These adjustments may be made in response to unusually cold or warm weather, environmental concerns or air pollution.
For example, Rome normally falls within Climate Zone D, meaning heating can operate from 1 November to 15 April for up to 12 hours a day.
However, for the 2026–2027 season, the city has introduced a different schedule through Municipal Ordinance No. 145/2026:
- Heating period: 15 November – 8 April.
- Daily limit: 11 hours.
- Maximum indoor temperature: 19°C, with a 2°C tolerance.
This demonstrates why residents should always check their local council’s latest announcements rather than relying exclusively on the national calendar.
What is the maximum permitted indoor temperature in Italy?
Italian heating regulations also establish maximum indoor temperatures to help reduce energy consumption.
Under Presidential Decree No. 74/2013, the weighted average indoor air temperature must not exceed:
- Residential and most other buildings: 20°C, with a 2°C tolerance.
- Industrial, craft and similar buildings: 18°C, with a 2°C tolerance.
However, local authorities can introduce stricter requirements. For example, some municipalities apply a residential limit of 19°C, plus a 2°C tolerance.
These limits are another reason to check local regulations, particularly if you live in an area affected by air-quality restrictions.
What happens if you don’t follow Italy’s heating rules?
Heating regulations are not simply recommendations. They form part of Italy’s wider energy-efficiency framework, and failure to comply can result in administrative penalties.
The precise penalties depend on the nature of the infringement and the applicable legislation. Building administrators and those responsible for managing heating systems also have obligations relating to their correct operation and maintenance.
If you live in a condominium, it’s worth checking the building’s internal regulations and contacting the administrator if you have questions about compliance.
Energy-saving tips for heating your home in Italy
Following the heating timetable is one way to manage energy consumption, but there are other steps you can take to keep your home comfortable during the Italian winter.
Here are a few practical suggestions:
- Bleed your radiators: Removing trapped air helps radiators distribute heat more efficiently.
- Install thermostatic radiator valves: These allow you to regulate the temperature in individual rooms and avoid heating spaces unnecessarily.
- Maintain your boiler: Regular servicing helps ensure your heating system operates safely and efficiently.
- Improve insulation: Draught-proofing windows and doors and improving insulation can help reduce heat loss.
- Use heating controls: A programmable thermostat can help you coordinate heating times with your daily routine.
These measures can make a difference to both indoor comfort and household energy bills.
