Boiler energy label

Boiler energy label

Boiler energy label, how to read the energy label of these appliances and information on the labeling of biomass boilers.

The energy labeling of allthermal plantsfor heating and the production of domestic hot water is mandatory since September 26, 2015, as required by EU regulation 811/2013.

The legislation provides for a doublelabelingone refers to the production of heat and the other to the system, so we speak of the system energy label.

L'energy label for heating systemsis related to:

  • Boilers
  • Water heater or boiler
  • Thermal plants
  • Biomass boilers (introduced on 1 April 2017).

The label applies to all heating systems up to 70 kilowatts of nominal power and to solar panels with tanks with a capacity of up to 500 liters.

How the energy label of a boiler is made

Like the energy label of household appliances, the first information we can identify concerns the energy class and the name of the manufacturer.

  • Name of the manufacturer and identification number of the device
  • Presence of a pictogram showing that the boiler can operate for the production of domestic hot water and / or for the production of heat.

Of fundamental importance is the energy efficiency class to which the appliance belongs. When there are two pictograms on the label and therefore the appliance in addition to producing heat also produces hot water, there are two scales of energy efficiency classes, one indicating the efficiency for heating and one referring to the efficiency for heating domestic water.

For mixed boilers (i.e. hot water production and space heating) the efficiency classes range from A +++ to D while for appliances that only provide water heating (water heater, boiler ...) the class goes from A + to F.

Like other household appliances there is no lack of pictograms that indicate:

  • the sound power level, to indicate the noise level, indecibel.
  • The rated heat output inkW.
  • The possibility of programming the production of hot water.

For more information on boilers or water heaters, please refer to the page: electric water heater, energy class.

Biomass boiler energy label

L'energy label for the biomass boilerwas introduced starting from 1 April 2017 by means of directive 2010/30 / EU. Thanks to'boiler energy label, consumers will be able to choose thethermal systemmore consciously.

Producers and distributors must comply with objective and uniform standards forenergy labeling of biomass boilers.

The label must explain to the consumer the energy performance of the system while the State, with random checks, will have to deal withto checkthat the information entered on the label corresponds to reality.

EEI index and energy class

Finally, as with alldomestic appliances, Even thepellet boilersthey must have an energy label.
The first information we find onenergy label of boilerscorresponds to the Energy Class, calculated according to the energy efficiency index (EEI).
This index depends on the energy performance of the boiler at partial power and at nominal power, in relation to electricity consumption, always at partial, nominal power and in stand-by phase. The higher the EEI, the higher (and more efficient) the energy class assigned to the heating system will be.

  • EEI greater than 150 corresponds to a class A +++
  • EEI between 125 and 150 corresponds to a class A ++
  • EEI between 90 and 125 corresponds to a class A +
  • EEI between 90 and 82 corresponds to a class A

The energy classes of pellet boilers can reach class G with an EEI below 30.

The energy label of the biomass boiler must comply with the energy labels of the household appliances, therefore contain information on:

  • Manufacturer's name and model identification code
  • Energy efficiency class
  • Consumption on an annual basis expressed in kW

In case ofenergy label of combined biomass plants, i.e. related to an energy accumulator in the form of hot water (puffer) or a solar collector system ... The label must also indicate the associated systems. In this case, the energy label must contain:

  • Manufacturer's name and model identification code
  • Heating function
  • Heat generation efficiency class
  • System energy efficiency class
  • Solar collector
  • Puffer
  • Adjustment
  • Additional heating
