The central condominium boiler: management and maintenance

The central condominium boiler is the plant that produces heating for all the units of the building from a single generator. Its management touches several fronts: metering of consumption, allocation of expenses, the possible disconnection of an owner and maintenance of the plant. Knowing the rules helps the administrator set correct allocations and avoid disputes among owners.

How heat metering works

In central plants, heat metering allows you to measure how much each unit actually consumes. A thermal energy meter measures the total energy produced by the boiler, while the heat cost allocators fitted on the radiators, or direct meters, record the consumption of the individual units. This system moves beyond allocation based on millesimal shares alone and ties much of the expense to each person's real consumption. Introducing metering responds to a legal obligation aimed at energy saving: where it is technically possible and economically worthwhile, central plants must be fitted with systems that measure individual consumption, so as to make each household accountable for its own draw.

Voluntary and involuntary consumption

The heating expense is split into two components. The voluntary consumption share depends on how much each owner chooses to use the plant and is allocated based on the allocator readings. The involuntary consumption share covers the losses of the distribution network and the common consumption independent of the individual's will, and is allocated according to millesimal or table criteria. This split, defined by the sector's technical standards, prevents those who consume little from paying like those who consume a lot, and vice versa. The percentage to attribute to the involuntary share depends on the building's characteristics and must be determined on the basis of a specific diagnosis or the values set by the technical standard, so that the criterion is defensible and not the result of an arbitrary choice by the meeting.

Disconnection from the central plant

The single owner may give up the use of the central plant and disconnect, provided that the disconnection does not cause notable operating imbalances or additional expense for the other owners. Verifying these preconditions is normally done with a technical report drawn up by a professional, certifying the absence of imbalances and additional costs. Disconnection concerns the right not to use the plant, not the right to escape any contribution, and it must be notified to the administrator so that it is taken into account in later allocations.

The expenses borne by the disconnected owner

Whoever disconnects is still required to contribute to some expenses. In particular, the disconnected owner continues to contribute to the extraordinary maintenance of the plant, to its preservation and to bringing it up to standard, as well as to the involuntary consumption share. Installing an autonomous boiler, therefore, does not exempt the owner from contributing to the replacement of the central boiler nor from the expenses on the common networks: these items remain the responsibility of all owners served by the plant.

Ordinary and extraordinary maintenance

Maintenance of the central boiler is divided into ordinary and extraordinary. Ordinary maintenance includes cleaning, periodic checks and adjustments that keep the plant efficient; extraordinary maintenance concerns major repair works or replacement of the generator. The ordinary maintenance expense normally follows the heating allocation, while extraordinary maintenance and replacement of the boiler fall on all owners according to the millesimal shares, including those who have disconnected. It is therefore important that the resolution approving a work on the plant correctly classifies the nature of the expense, because who pays and to what extent depends on that classification, and a mistake on this point is among the most frequent causes of dispute between served and disconnected owners.

Checks, the plant logbook and responsibility

The central boiler is subject to obligations to check energy efficiency and emissions, at intervals set by the rules. The plant must have an up-to-date plant logbook, which gathers the technical data and the works carried out. For plants above a certain power, the appointment of a third party responsible for operation and maintenance is required. Keeping checks and documentation in order is the administrator's task, who answers for it to the owners and to the supervisory authorities. Failure to carry out the mandatory checks or the absence of an up-to-date logbook can lead to penalties, as well as exposing the condominium to risks in the event of an accident.

Managing the central boiler with management software

Condominium management software lets you set the heating allocation criteria, distinguish the voluntary share from the involuntary one, manage the positions of disconnected owners and keep track of maintenance and inspection deadlines. Having the readings, the tables and the deadlines in one place makes allocations transparent and reduces disputes in the meeting.

AmministraPro lets you allocate heating expenses between the voluntary and involuntary shares, manage disconnected owners and record the plant's maintenance deadlines. You can see how it works on the features page or compare the plans in the pricing section.
