Disconnecting from central heating: imbalance and costs

An owner may disconnect from the central heating system, but only under precise conditions. Article 1118 of the Italian Civil Code allows waiving the use of the system if the disconnection does not cause significant operating imbalances or extra costs for the other owners. Anyone who disconnects still remains bound to pay for extraordinary maintenance, conservation and bringing the system up to standard. The burden of proving the absence of imbalance falls on the party requesting disconnection.

What Article 1118 of the Civil Code provides

The rule, as amended by the condominium reform, provides that an owner may waive the use of the central heating or air-conditioning system when disconnection does not cause significant operating imbalances or extra costs for the other participants. The legislator thus balanced two needs: the individual's freedom to choose an independent system and the protection of the condominium community, which must not suffer a worse service or higher costs.

The concept of significant imbalance

An imbalance occurs when removing one user alters the proper functioning of the system for the others: for example when the radiators of the remaining units no longer reach the design temperature because the boiler was sized for all users. Case law has noted that the imbalance may not be significant with one or two disconnections, but becomes so with the third or fourth, depending on the number of units served. The first owners may therefore disconnect, while later ones may not be able to.

The burden of proof on the disconnecting owner

The Court of Cassation clarified that the owner intending to disconnect bears the burden of showing that disconnection produces no significant operating imbalance nor extra cost for the others. This proof cannot be generic: it must be provided with specific technical documentation, normally an expert report drawn up by a qualified professional analysing the system and certifying the absence of negative consequences. Without such proof the disconnection is not lawful and the condominium may object.

The costs the disconnected owner still pays

Disconnection does not free the owner from every obligation. Even after disconnecting, they continue to contribute to certain cost items because they remain co-owner of the common system:

• Extraordinary maintenance of the central system
• Costs for conservation of the system
• Compliance work required by law

Excluded, on the other hand, are the consumption and ordinary maintenance costs tied to running the heating, which the owner no longer uses. The distinction between consumption costs and conservation costs is delicate and must be handled carefully in the allocation.

The correct disconnection procedure

An owner intending to disconnect should notify the manager in advance, attaching the technical report certifying the absence of imbalance and extra cost. The manager brings the matter to the meeting, which reviews the documentation. Strictly speaking disconnection does not require the meeting's authorisation when the legal conditions are met, but a prior discussion reduces the risk of litigation. In case of dispute the decision rests with the judge, who assesses the report.

Why transparency pays off

Handling a disconnection without adequate documentation almost always generates conflicts and challenges. The manager has every interest in keeping a trail of the report, the notice and the subsequent allocation tables that account for the disconnected owner's position, separating conservation costs from consumption costs. Orderly management protects both the condominium and the individual.

AmministraPro lets you manage differentiated allocations for disconnected owners, keeping conservation costs separate from consumption costs and archiving the technical documentation linked to the system.
