What information do the energy labels on your household appliances actually contain?

Energy labels inform you how much energy a device consumes, so that you can take this information into account when making a purchase.

Knowing exactly how to decipher them, is indeed very important! Below is an overview of the most common labels.

Energy labels on household appliances

The EU mandated energy labels are the best known. They divide your dishwasher, air conditioning installation, television, electric heating, etc. into letters and colours, ranging from extremely energy-efficient (green) to extremely energy-consuming (red).

Currently household appliances are classified with letters ranging from A+++ (most energy-efficient) to D (less energy-efficient). With effect from March 2021, however, this labelling will change into letters ranging from A to G.

Energy labels for heating installations

According to a European directive, as of September 2015 heating systems must be classified on a scale of A to G, by analogy with the household appliance.

Gas boilers

Only condensing boilers satisfy the label's strict criteria and are awarded the Class A energy label.

If your boiler predates 2015, then it may have the Belgian HR+ label (traditional heating boilers) or HR Top label (condensing boilers).

Oil boilers

Pre-2015 installations have the Optimaz or Optimaz Elite label:

  • The Optimaz label applies to boilers with an efficiency of less than 93%
  • The Optimaz Elite label applies to boilers with an efficiency of less than 97.5%

Energy labels for air conditioning and cooling

Eurovent Certification is based on European and international standards for classifying the performance of air conditioning and cooling installations.

Energy labels for sustainable installations

The European Union Ecolabelling Board has an eco-label that applies to high-efficiency heat pumps which work with environmentally friendly cooling gases. It applies to heat pumps operating on natural gas or electricity.

The Quest label enables the distinction between small installations with renewable energy that satisfy extremely precise technical requirements. In Belgium there are 3 Quest/Construction Quality labels:

  • SOLAR PV for installers of solar panels
  • SOLAR THERMAL for installers of solar boilers
  • HEATPUMP for installers of heat pumps
