Since 26.09.2015, the ErP Eco-Design Directive (ErP = Energy related Products) has been binding for heat generators and water storage facilities in Europe. This means that the energy efficient design and labelling of energy related products, which we already know from refrigerators, washing machines, etc., will also apply to heat pumps and water heaters.
The EU directive focuses on improved energy efficiency and environmental compatibility of energy-related products . These minimum requirements for environmentally design are communicated transparently with the ErP label and its mandatory technical data.
The most important and best-known specification is the energy efficiency class. Heaters are rated on a scale from G to A++. Domestic hot water tanks are classified from G to A.
The highest level A+++ is currently only given to devices that use a large proportion of renewable energies, such as the heat pump.
Heat pump owners therefore opt for one of the most sustainable solutions.
