Miele Professional has a new range of commercial tumble dryers which are heated using waste or spare hot water.

The H2O dryers, designed to reduce heating and running costs, can use water from a variety of sources including solar-thermal energy, district heating, an on-premise co-generation plant or residual heat from a laundry.

The hot water is used to heat air in a heat exchanger. This new type of heating will be available on tumble dryers with various load capacities, ranging from 325 l to 800 l models for 10 to 32kg of laundry. All models feature Miele's honeycomb drum.
