Washing and drying at reduced costs

H2O dryer and other innovations slash consumption

(PresseBox) (Gütersloh, ) Miele Professional optimises energy balance in laundries with innovations such as its new H2O dryers which are heated at little expense using available hot water and with heat-pump dryers which cut electricity consumption by up to 60%. But other Miele laundry machines also help cut costs, too: Tumble dryers, flatwork ironers and washer-extractors can be run on gas. In the case of washer-extractors, a value-for-money hot water connection is also available to further tweak the energy balance in selected programmes.

The new H2O dryers are available with 8 different load capacities ranging from 10 to 32 kg with drum volumes from 325 to 800 l. The principle of operation: Hot water, centrally heated using solar-thermal power or district heating or heated in the laundry itself, or even as a by-product of cooling a co-generation plant, heats the process air in the tumble dryer in its heater bank. The programmes on these machines have been specially designed to operate at lower process air temperatures.

If the source of hot water is a co-generation plant, H2O dryers have virtually no consumption at all. In this case, the hot water is a by-product of cooling the generation plant and does not need to be heated separately. This approach also offers the additional benefit of cooling the water in the H2O dryer for reuse as cooling water in co-generation.

In fact, if the heat produced by a small heating power station cannot be used by, say, a tumble dryer or a swimming pool, the co-generation plant may even have to be switched off with the result that cheap electricity may temporarily be unavailable. Looked at from this point of view, the new dryer makes an invaluable contribution towards the efficient use of existing energy. First pilot units have proved their validity in field trials already.

Energy bills can also be slashed by the three heat-pump dryers available from Miele with load capacities ranging from 6.5 to 16 kg. These operate with a closed air circuit and therefore do not require vent ducting. This also makes them incredibly simple to install. The principle of heat-pump drying revolves around keeping waste heat inside a closed circuit by using heat exchangers. This saves energy, protects the environment and goes easy on both budgets and textiles. Heat-pump dryers operate at lower process air temperatures, thereby ensuring the particularly gentle drying of fabrics. As their rated loads and current consumption lies far below those of comparable conventional electric dryers, they can be deployed wherever circuit fuse ratings are low or where there is a need to avoid peaks in current draw.

Reduced running costs using gas

Switching to gas heating can also reduce operating costs. Miele Professional offers washer-extractors, tumble dryers and flatwork ironers which run on this advantageous source of energy. As the price of gas is considerably lower than that of electricity - in German it costs only around one-third - a switch to gas can result in considerable economies.

Furthermore, washer-extractors from the latest generation offer optimised programme cycles to further reduce energy requirements: The optimised 'Cottons 60°C' programme on a 13 kg machine, for instance, reduces water consumption in combination with a hot-water fill to below 10 l/kg, without compromising either washing or rinsing performance. The new 'Eco' programme requires even less water: Specific consumption is as low as 7.5 l and 0.03 kWh per kg. With additional modules such as the laundry weighing system, washer-extractors from Miele Professional make a further huge contribution towards reducing costs: This feature registers and shows the weight of laundry in the display and reduces running costs on less-than-full loads automatically.
