The collective heating meter to reduce energy consumption

The collective heating meter to reduce energy consumption. The energy consumption of buildings is the workhorse of today’s green administrations. To limit household expenses, regulations have therefore evolved in order to encourage the French to monitor and reduce their heating consumption. Details.

The individualization of heating costs, a regulatory obligation


Only condominiums whose consumption is less than 80 kWh per square meter, buildings that do not allow the installation of collective heating meters at the individual level or even professional hotel premises are exempt from this measure.

On the other hand, it is necessary to have a collective heating meter installed at the entrance to each apartment, making it possible to measure its heating consumption. These continuously measure the temperature difference between the radiator and the housing to deduce the energy consumption.

Differences between a Heating Cost Allocator and a Thermal Energy Meter


To reduce the energy consumption of collective housing, you may come across 2 different systems.

The thermal energy meter (CET) will make it possible to know the real consumption of a household, in order to individualize the invoices, but also to be able to take actions in order to reduce its consumption. For this, the heat meter will measure 2 things, namely

  • water flow
  • the temperature of the water when it enters and leaves the circuit

The CET is preferred in the case of a collective heating system with horizontal distribution, in other words by closed-loop. For the first, it is radio relief, in other words, radio waves. This requires the trip of a technician. He can do the reading from the outside thanks to his PDA. The second solution is remote reading. Everything is done remotely and in real-time.

Again, the RFC will also work with 2 probes. To take the reading of all the dispatchers in the building, it is identical to the CET.

In terms of the costs generated by these installations, there is also a difference in terms of the subscription, but also on the installation. On average, the subscription is more expensive by just over 10 euros for the CET. The installation will also be a little expensive with the CET, in particular because of the compliance visit.

The individualization of heating costs, an effective device?


According to the French Environment and Energy Management Agency, this regulation would reduce the average household heating bill by 15%. The idea here is to allow each household to take responsibility and not pay for the entire community of its habitat. The individual collective heating meter, like the heating cost allocators, makes it possible to apply temperature recommendations and therefore save money!
