Miele received the Eco Design Prize for its G 6000 EcoFlex dishwasher with heat store technology. The prize has jointly been awarded by the Federal Ministry for the Environment, Nature, Construction and Reactor Safety, the Federal Environmental Agency and the International Design Centre Berlin. The award was presented in Berlin by Maria Krautzberger, President of the Federal Environmental Agency. The EcoTech heat store is a device that utilises heat from rinse water from the previous water intake to preheat the water for the next main wash, thereby reducing energy consumption considerably. The EcoTech heat store is located in the side panel and consists of two separated water circuits. One of these circuits transports fresh tap water; the other constitutes a series of loops. The latter contains hot water from the last programme stage which is circulated to pre-heat the fresh water in the reservoir. This means that less electricity is required to heat the incoming water to the required temperature, improving the energy efficiency rating from A+++ to A+++ minus 20%. Besides, all EcoFlex dishwashers can be connected to a hot water supply for further savings.
