Disconnecting from Central Heating: The Rules

An owner may give up the use of the central heating or air-conditioning system by disconnecting his own unit, if the disconnection does not cause significant operating imbalances or extra costs for the other owners. This is provided by Article 1118 paragraph 4 of the Italian Civil Code. Even after disconnection, however, the person giving up remains obliged to contribute to the costs of extraordinary maintenance of the system, its conservation and its compliance upgrading, because he remains a co-owner of the common property. It is a work by the individual that directly affects a shared system.

A conditional right, not a free one

Disconnection is not a free and unconditional choice. The law allows it only if two negative conditions are met: the absence of significant operating imbalances of the system and the absence of extra costs for the other owners. If even one of these conditions is not met, the disconnection is not lawful. Meeting authorization is not required, but the owner must be able to prove that his disconnection does not harm the community.

The role of the technical expert report

To prove the absence of imbalances and extra costs, a technical report drawn up by a qualified professional is generally necessary. The report assesses the behavior of the system after the single unit is disconnected and certifies that operation remains correct for the others and that their costs do not increase. It is good practice to send the report to the manager before proceeding, so as to allow a check and to establish evidence in advance in case of dispute.

• Disconnection is allowed only without significant operating imbalances.
• It must not result in extra costs for the other owners.
• A technical report is needed to certify compliance with these conditions.
• The person giving up remains a co-owner and contributes to conservation and compliance upgrading.

Which costs remain due after disconnection

Whoever disconnects no longer pays the fuel consumption for heating his own unit, but remains liable for some items. In particular he contributes to the costs of extraordinary maintenance, conservation and compliance upgrading of the central system, of which he remains a co-owner and which he could return to using at any time by reconnecting. He also remains liable for operating costs to the extent that the disconnection has not resulted in an actual reduction of the burdens on the others.

The distinction between consumption and conservation

The key to allocating the costs correctly is to distinguish the two components. The share linked to actual consumption follows the real use of the system, measured by metering devices, and does not fall on the disconnected unit for the heat it does not receive. The share for conservation and extraordinary maintenance, on the other hand, concerns the common property in its substance and continues to fall on all co-owners, disconnected ones included. Confusing the two items is the most frequent cause of allocation errors.

Heat metering and regulatory obligations

The rules on condominium heating intertwine with the obligations of heat metering and thermal regulation, which require part of the costs to be allocated according to the actual consumption measured and part according to the thousandths (millesimi) or installed power. The reference technical standard for the allocation is UNI 10200. A system equipped with metering also makes the management of disconnections simpler and more transparent, because it allows the consumption share of the disconnecting unit to be isolated.

Advice for the manager

Faced with a disconnection request, the manager should obtain the expert report, verify the absence of imbalances and extra costs, inform the meeting and update the allocation plan keeping the consumption and conservation shares distinct. A transparent allocation, documenting why the disconnected unit pays some items and not others, prevents disputes and challenges. Keeping the report and the minutes is essential in case of future controversy.

Managing differentiated heating allocations, with consumption and conservation shares distinct for the disconnected units, is easier with specialized software. With AmministraPro you can set allocation criteria consistent with heat metering, archive disconnection reports and produce clear statements for the meeting.
