Heat Cost Allocator vs. Heat Meter – Which Is Best for Your Apartment Building?

Heat cost allocator and heat meter are two of the most widely used technologies for tracking heat consumption and ensuring fair billing in multi-apartment buildings. As heating continues to be one of the biggest recurring expenses, finding a smart and efficient solution is no longer optional — it's essential.

In many buildings, heating costs are still divided equally among residents, regardless of how much heat each apartment actually consumes. This outdated method leads to frustration, overpayments, and a lack of motivation to save energy.

In this article, we compare heat distribution meters and heat meters — their functions, benefits, limitations, and which solution may be better suited to your building's technical setup and future compliance with EU regulations.

What Is a Heat Meter?

A heat meter is a device that precisely measures energy consumption in kilowatt-hours (kWh). It is typically installed on the building’s main heating pipe or on individual apartment inlets — if the system supports it.

Advantages of Heat Meters:

  • Accurate energy measurements in real units (kWh)
  • Easy integration with centralized billing systems
  • Compliance with EU energy regulations
  • Clear billing methodology that’s easy for residents to understand

Limitations:

  • Only compatible with horizontal heating systems
  • May require additional technical modifications
  • Cannot measure consumption per individual radiator

What Is a Heat Cost Allocator?

A heat distribution meter is a compact electronic device installed directly on each radiator. Instead of measuring water flow, it detects the radiator’s heat output and calculates the apartment’s share of total heating based on these readings.

Advantages of Heat Cost Allocators:

  • Pay only for the heat your radiator emits
  • Compatible with most heating systems, including vertical systems
  • No need to reconfigure the existing heating system
  • Easily combined with thermostatic radiator valves (TRVs) for savings of up to 22%

Limitations:

  • Readings are relative, not in kWh
  • Requires calibration and a standardized distribution model across the building
  • Cannot track individual radiator performance in absolute units

Comparison Table

Criteria Heat Meter (kWh) Heat Cost Allocator
Measurement type Absolute (kWh) Relative (heat distribution)
Installation in apartments Limited (horizontal only) Possible in almost all cases
Heating system requirements Horizontal systems only Also works with vertical systems
Installation cost Higher Lower
Integration with TRVs Easy and effective Easy and effective
EED 2027 compliance Yes Yes (with remote reading)

Which Option Should You Choose?

If your building doesn’t support individual meters in each apartment — which is often the case in Latvia and many other EU countries — heat distribution meters are a more practical and economical choice.

When paired with thermostatic radiator valves, allocators provide:

  • More accurate heat distribution
  • Fair and transparent billing
  • Up to 22% savings on heating bills
  • Full compliance with EED 2027

The EED 2027 Directive: Are You Ready?

Starting in 2027, the European Union mandates that all residential buildings must have remote and transparent heat metering systems. Heat cost allocators with wireless data transmission already meet this requirement — meaning you’ll avoid last-minute installations or regulatory risks.
