Decision-making aid for buying a new heating system: The new energy efficiency identification, standardised throughout Europe, is coming for heating systems too.


Refrigerators, televisions and washing machines have been identified with an energy efficiency label for several years now. From 26 September 2015, this identification will also be compulsory for heating technology. Individual components – heat generators and DHW cylinders – as well as complete heating systems will be identified with energy efficiency labels in future.

Making energy consumption more transparent

The new designation of heating technology with efficiency labels is based on directives and regulations from the European Union (EU). This means that the designation is standardised throughout Europe and that the calculation is based on procedures defined by the EU Commission. This provides you with a basis for comparison and hence a decision-making aid for new purchases or modernising a heating system.

Everything from a single source: matching heating systems for greater efficiency

Energy efficiency labels provide good guidance. Nevertheless, you should never make the decision to buy a heating system solely based on the label. Heating systems are complex. Their efficiency is not only influenced by the individual product, but also by the perfect coordination of all components.

Efficiency label for heating systems

Different information can be found on the efficiency labels. The example here is for a condensing boiler. Not only do they specify the energy efficiency class, indicated with a black arrow, but also the rating or noise emissions of the appliance.
 


Product labels and their efficiency classes

The individual components of a heating system are provided with a product label. For heat generators, the best efficiency class is designated with A++ and the worst with G. For DHW cylinders, the scale extends from A to G. On combi boilers used for both central heating and DHW heating, the classification is indicated separately for the two applications.

More informative than the product label: the composite label

Heating systems consist of several components, all of which influence the efficiency of the overall system. For this reason, product labels have been supplemented with composite labels. They indicate the energy efficiency of the system as a whole. Consequently, for example, a Smart Home system can increase the efficiency of a heating system.

If all components are perfectly matched, the composite label frequently indicates a better energy efficiency than that of the individual product labels. Only the composite label provides you with an indication of how efficient a heating system really is in.
