The ErP Directive for Heat Pumps

The deadline for the energy efficiency of space and combination heaters to be labelled EU-wide is 26 September 2015. The benefits of heat pumps are immediately visible, unlike fossil-fuelled or pellet-fired heating systems. Heat pumps consistently achieve green ratings (A+ or better).

The Energy Labelling Directive relates to units with a nominal output of up to 70 kW. What is crucial here is that a single annual energy consumption figure does not work on labels, unlike say on a washer-dryer or refrigerator. The consumption of a heating unit always depends on the building in which it is installed, explaining why the classification is based on “seasonal space heating energy efficiency”.

We have made available all the technical data sheets on our air conditioning and heat pump systems.

To the data sheets

A Focus on Efficiency and Comfort

The ErP Directive also defines the maximum sound power level for heat pumps depending on the heat capacity of the heat pump. The energy label carries the figures. The label shows the sound power level of the indoor and outdoor unit in decibels as an objective acoustic variable.

Schalldruckpegel - Heizen

Sound Pressure Level dB(A)

The sound pressure level is a sound field variable and gives the operating noise of an indoor or outdoor unit perceived at a specified distance.

Schallleistungspegel - Heizen

Sound Power Level dB(A)

The sound power level is an acoustic variable that defines the source strength of the sound generator and thus is independent of the distance to the receiver.

The technical data sheets for the units give the sound power level as well as the sound pressure level. It describes in acoustics the metrologically recorded level generated by a sound source at a specific distance.

Climate Zones for Heating Mode

Climatic conditions play a key role in evaluating heat pumps. They are split into three climate zones on the energy label: cold, moderate and warm. The measuring points are at -7 °C, 2 °C, 7 °C and 12 °C. Unlike with air conditioning units, the climate zones on the energy label for heat pumps are coded in shades of blue.
