BAM investigates energy efficiency of heat pumps

For energy-efficient heating pay attention to the energy efficiency label when buying heat pumps or other heating devices.

The Bundesanstalt für Materialforschung und -prüfung (BAM) has been checking the energy consumption of heat pumps. A team of BAM experts has commissioned the testing of 20 prominent models from different manufacturers at independent, accredited laboratories. BAM’s conclusion is that there is no deviation between measured values and declared energy values on the labels for all models checked so far.

In winter, a warm home is indispensable. But those who heat their house extensively are often surprised when looking at the bill because heating consumes the most energy in the household. An intelligent heating technology can help reduce energy consumption. Using a heat source from the environment is both efficient and environmentally friendly. A heat pump can extract heat from the soil, groundwater or outdoor air and use it for space heating or to produce hot water.

In Europe, heating systems are divided into energy efficiency classes to make it easier for consumers to choose the right system. These classes have been mandatory for heat pumps since 2012. Using the example of heat pumps, BAM scientists are currently investigating as part of the NAPE project "Market Surveillance Support” if the product information on their energy consumption is correct. They want to assess weaknesses of the test methods and improve the tests. This also helps support market surveillance.

"Compliance with ecodesign and energy labelling requirements needs to be monitored effectively. This requires extensive technical testing so that market surveillance authorities can prove to the courts that the product does what it says on the label and that includes energy efficiency," said Dr. Floris Akkerman, head of Ecodesign and Energy Labelling at BAM.

Because market surveillance in Germany falls under the states’ authority, BAM scientists are cooperating closely with them in the project. The project’s findings are meant to assist market surveillance authorities and help create equal competition on the market. At the same time, it aims to increase consumer confidence in the energy efficiency label on products and in datasheets.

The Market Surveillance Support project is one of many measures in the National Energy Efficiency Action Plan (NAPE) of the Federal Government. NAPE’s goal is to halve primary consumption by 2050.

About BAM

BAM promotes safety in technology and chemistry.
As a BMWi departmental research institute, BAM performs research, testing and offers advisory support to protect people, the environment and material goods. Its activity in the fields of materials science, materials engineering and chemistry is focussed on the technical safety of products and processes.

BAM’s research is directed towards substances, materials, building elements, components and facilities as well as natural and technical systems important for the national economy and relevant to society. It also tests and assesses their safe handling and operation. BAM develops and validates analysis procedures and assessment methods, models and necessary standards and provides science-based services for the German industry in a European and international framework.

Safety creates markets.
BAM sets and represents high standards for safety in technology and chemistry for Germany and its global markets to further develop the successful German quality culture "Made in Germany“.
