Boiler room costs: how they are split

The boiler room of a condominium generates several categories of cost that the manager must know how to distinguish and allocate correctly. These range from the cost of fuel or energy to running the system, from ordinary to extraordinary maintenance, up to mandatory checks and certifications. Each item follows a different allocation criterion: some are split by consumption, others by thousandths, and others still involve disconnected owners too. Orderly management avoids errors and disputes.

The main cost items

Managing a boiler room includes recurring and occasional items. Among the main ones:

• Fuel or energy for heat production
• System operation and third-party responsible service
• Ordinary maintenance of boiler, burner and components
• Energy efficiency checks and flue gas analysis
• Extraordinary maintenance and component replacement
• Insurance and system safety obligations

Distinguishing these items is the first step to applying the correct allocation criterion to each.

Ordinary and extraordinary maintenance

Ordinary maintenance covers the periodic work that keeps the system efficient and safe: boiler cleaning, burner checks, seal inspection, flue gas analysis. These are recurring, predictable costs. Extraordinary maintenance instead concerns non-repetitive, high-value work such as replacing the boiler, the burner or major parts of the system. This distinction is crucial, because the owner disconnected from the system continues to contribute only to extraordinary maintenance, conservation and compliance costs, not to ordinary operating costs.

How the fuel cost is split

The cost of fuel or energy is the most significant item and must be split by distinguishing voluntary from involuntary consumption, under the rule that at least 50% of the total cost of the service is attributed to actual consumption measured by the meters. The remaining fixed share is split by heating thousandths or the criterion approved by the meeting. In condominiums without metering, pending compliance, allocation is by thousandths alone, with the risk of resolutions that do not comply with the rules.

Operation and the third-party responsible

Operating the system covers switching on, switching off, supervising and regulating the boiler room during the heating season. For systems above certain power thresholds, the rules provide for a third-party responsible, a qualified technician to whom the condominium entrusts the operation and maintenance of the system. Its cost is an ordinary management expense, normally split by heating thousandths.

Mandatory checks and the plant logbook

The rules require periodic energy efficiency checks and keeping the plant logbook, with inspections whose frequency depends on the type and power of the generator. These obligations fall on the condominium and generate recurring costs that the manager must schedule to avoid the system falling out of compliance and incurring penalties. Keeping track of inspection deadlines is an integral part of good management.

The importance of orderly accounting

The variety of items and allocation criteria makes the boiler room one of the most delicate accounting sections. Confusing an ordinary cost with an extraordinary one, or applying the wrong criterion, leads to allocation errors and disputes at the meeting. The manager must keep the items separate, document the work and produce a clear statement showing how each unit's cost was calculated.
