Air to water heat pump > Renewable Energy



European Directive 2009/28/CE, dated 23 April 2009, defines the air to water heat pump as a renewable energy.

In 2007 the European Union determined certain targets to gradually reduce the emission of greenhouse gases, to look for alternatives to use instead of current energy sources and to achieve greater efficiency and improved performance in the use of new products.

Our responsibility to the environment, the efficient use of scarce energy sources and the growing price of energy attract the public’s attention more and more towards efficient energy systems and the use of renewable energies in the heat generation market.
The “20:20:20” target fixed by the EU should be reached by 2020:

Reducción de las emisiones de dióxido de carbono en un 20% en relación a 1990

Aumento del porcentaje de energía renovable sobre el consumo total de energía en un 20%

Aumento de la eficiencia energética en un 20%

Part of this European strategy foresees that heating systems in buildings will also use renewable energy sources in addition to traditional fossil fuels. This will help achieve the target of increasing energy efficiency in homes and offices, requiring less energy to reach the same level of comfort. This is what efficient and modern heating systems like air to water heat pumps do.

The Ecodesign ruling (ErP) establishes minimum requirements for energy efficiency, NOx emission and noise levels for heating systems made in Europe. The idea is to reduce the emission of adverse and greenhouse gases in order to limit the environmental impact of the whole life cycle of a product, with special emphasis on the design and manufacturing stage in order to improve energy efficiency.

The energy label provides information about the energy efficiency of each product. There are two different classifications for heating and hot water. On products that provide both services the labels should indicate both classifications.

The classification system distinguishes between heat pumps for central heating in energy efficiency categories from A++ to D for heat pumps, and from A to G for DHW tanks. In August 2019 a more rigorous scale will be introduced, from A+++ to D for heat pumps and from A+ to G for DHW tanks.

La norma de etiquetado energético tiene como objetivo proporcionar información sencilla al consumidor sobre la eficiencia de los productos de calefacción que desea adquirir.
