Configuring the UNI 10200 heating table in the software
In a condominium with central heating and heat metering, the expense is not allocated by thousandths (millesimi) but according to the UNI 10200 standard, which distinguishes the voluntary consumption share, tied to how much each unit draws, from the involuntary thermal power share, tied to the system's losses. Configuring this table well in the software is essential to produce correct balancing charges that hold up at the owners' meeting. This guide explains how to set the two components, how to record the thermal-demand thousandths, how to enter the heat allocator readings and how to handle special cases such as a unit disconnecting from the system.
What UNI 10200 provides
The UNI 10200 standard sets the criteria for allocating the costs of winter climate control and domestic hot water production in central systems fitted with metering. The expense is split into two parts: voluntary consumption, measured by allocators on the radiators, and the involuntary share, which covers network losses, running and installed power.
The involuntary share is not allocated by ownership thousandths, but by thermal-demand thousandths computed by a technician, which account for the position and heat loss of each unit. This is the figure that makes UNI 10200 different from an ordinary thousandths table and that must be recorded precisely in the software.
Setting the two components in the software
In the software you create a table dedicated to heating, distinct from the general table. This table is assigned the split percentage between consumption share and involuntary share, as defined by the system's technical report. The percentage is not arbitrary: it derives from the designer's energy calculations.
The consumption share is distributed over the allocator readings, while the involuntary share is distributed over the thermal-demand thousandths. By recording both bases in the software, the calculation sums the two parts for each unit and produces the amount due, ready for the balancing charge.
- Create a heating table separate from the general thousandths
- Set the percentage between consumption and involuntary share
- Record the thermal-demand thousandths for the fixed share
- Link the allocators to their respective units
Readings, balancing charge and advances
During the year owners pay advances based on the budget, while at the end of the season the actual allocator readings are entered and the balancing charge is computed. The software compares each unit's amount due with the advances paid and determines the balance, in debit or credit.
It is important that the sum of the shares matches the actual cost of fuel and running. A gap between the sum of individual readings and the general consumption is normal, and the unmetered part falls within the involuntary share, consistent with the design of the standard.
Special cases and verification
A frequent case is disconnection from the central system. An owner who disconnects remains bound to contribute to extraordinary maintenance and preservation costs, plus the share for imbalances, under Article 1118 of the Italian Civil Code. The software must allow this position to be handled without excluding the unit from the table entirely.
Before the balancing charge it is worth simulating the allocation and checking that it balances. With AmministraPro you can configure the UNI 10200 table with consumption and involuntary shares, handle thermal-demand thousandths and disconnections, and produce the seasonal balancing charge. The features are described on the /funzioni page, the plans on the /prezzi page.
Frequently asked questions
Why is heating not allocated by ownership thousandths?
Because in central systems with metering the UNI 10200 standard requires charging actual consumption, measured by allocators, plus an involuntary share based on thermal-demand thousandths. Ownership thousandths reflect neither the real consumption nor the heat loss of each unit, so they are not the correct criterion.
What are thermal-demand thousandths?
They are values computed by a technician expressing the involuntary thermal power share attributable to each unit, accounting for position, exposure and losses. They serve to allocate the fixed part of the heating expense under UNI 10200, and must be recorded in the software as the basis of the involuntary share.
How do I handle an owner disconnected from the central system?
A disconnected owner does not pay the voluntary consumption share, but remains bound to extraordinary maintenance, preservation and any imbalance costs, under Article 1118 of the Italian Civil Code. In the software you configure this by excluding them from consumption while keeping them in the shares owed, so the allocation stays compliant.
Do I choose the split between consumption and fixed share myself?
No, not freely. The split between voluntary consumption and involuntary share derives from the system's technical report drawn up under UNI 10200. In the software you enter that value. Only where the technical conditions are absent may the meeting resolve a different criterion, with the required majorities.
