Saving on Electricity and Water is Worthwhile
Especially Economical Household Appliances 2006/07

Consumer Information

Refigerators and freezers, wahsing machines and dishwashers, as well as washerdryers and driers, are purchases for many years of service. Along with good performance, above all they should be reliable and have a long life. Furthermore they should be economical. Low power and water consumption leads to lower operatoing costs and less environmental loading For many appliances, the operationg costs over their lifetime are higher than the purchase price. Especially economic appliances thus save more on power and waters costs over the years than the purchase price. In Germany, in the fall of 2006 roughly 2,100 different refrigerators and freezers, 500 washing machines, 600 dishwashers, 190 driers, and 40 washer-driers are offered. Among these are some especially economic models many with moderate, and still a certain number with high power and water consumption. The differences in consumption are often only in terms of "decimal places". However, one should not be deceived here: For washing machines, 20 liters more water each use causes additional costs of 234 over 15 years. For refrigerators and freezers, 100 kWh more cause additional electricity costs of 225 over 15 years, plus possible price increases. The most economical tabletop refrigerator with */*** compartment saves about 400 over 15 years, compared with the model with the highest power consumption. A higher price of e.g. 200 is therefore a very prifitable investment. This leaflet summarizes especially economical models of the common designs and size classes. It should serve as orientation for taking low power and water consumption into account. The information is based on market data from 2006. Should you read this brochure at a much later time or not find the information you seek here, please look in the Internet under www.spargeraete.de. In this online database, you will find the entire up-to-date German offering known to the authors of this brochure.

Energy Efficiency and the "EURO label"
Consumers require simple orientation in order to be able to compare the power and water consumption of household appliances without complicated calculations. For different designs, sizes and performance, this is often difficult. At first glance the Euro label, with its simple A - G classification for energy efficiency appears to be helpful. One would think that A units would be altogether efficient in their energy consumption and G units, on the other hand, grossly wasteful, with B units presumably well above the average. Unfortunately, this is very deceiving, since the A - G scale agreed on more than 12 years ago in connection with the energy consumption labeling ordinance is entirely obsolete for many designs. It is more often deceiving than showing the way to savings. The extended scale with A+ and A++ introduced at the beginning of 2004 is helpful only in connection with refrigerators and freezers.

For washing machines, n.e.= not existing in this size. Source: NEI household appliance database, August 27, 2006 there are also A - G labels for washing effectiveness and spinning effectiveness at maximum speed. These data apply to the Cotton 60 washing program. How economically or cleanly a washing machine washes with other programs can not be recognized on the basis of this label. A criterion for how well the washing powder is rinsed away the end does not exist at all. For driers, an A to G scale exists only for energy efficiency. This applies to the drying program "Cotton completely dry" and for laundry previously spin-dried at 800 rpm. Caution, however: The consumption data in kWh in the catalog apply, depending on the manufacturer, for laundry spin-dried at 800, 1000 or even 1400 rpm and can therefore often not be directly compared. Whoever spin-dries laundry at a higher speed achieves increasingly lower rates of consumption. For washer-driers (washing machines with a drying function), an A to G scale applies for the energy efficiency and the washing effectiveness. The values apply for the overall washing and drying process in the program combination "Cotton 60C" for washing and "Cotton cabinetdry" for drying. For dishwashers, there are A to G values for the energy efficiency and for the cleaning and drying effectiveness. Other than for washing machines, here the manufacturers themselves can define the appropriate dishwashing program, but must specify this.

A number of factors determine the power consumption of refrigerators and freezers: the technology, the thermal insulation of the housing, the efficiency of the cooling system, the ambient temperature at the given location, and the type of use. The cooler the location, the lower the power consumption. However, it is also necessary to pay attention to the climatic category of the unit. Units of climatic category SN (subnormal) are suited to use with temperatures from 16C to 32C, e.g. in normal kitchens. For warmer locations, the climatic categories ST (subtropical), suited for ambient temperatures from +18C to +38C, or T (tropical), suited for ambient temperatures from +18C to +43C, may be appropriate. At excessively cold ambient temperatures, the thermostat of the unit may not function correctly. At excessively high ambient temperatures, the power consumption increases drastically and it may not be possible to maintain the required inner temperature, or the unit may be overloaded. Locating the unit next to a stove, dishwasher, heating or under direct sunlight is therefore always unfavorable.
Climatic categories and location
It is also important that sufficient air can reach the heat-exchanging surfaces of the unit, which are usually located on the rear of the unit, but occasionally also on the sides. This requires sufficiently large air openings, which must be kept open at all times. The power consumption required for operation can be kept to a minimum by opening the door as infrequently as possible and not leaving open when not necessary, as well as placing food into the unit only after it has cooled off. In this way, less warm, moist air and water vapor enter the unit, reducing the frequency of defrosting.

Refrigerators and freezers have seven different temperature zones, suited to the storage or freezing of different foodstuffs. The classic freezer compartment has +5C inner temperature and can keep milk products, cold cuts and cheese fresh over a few days' time. The somewhat warmer main storage compartment has a temperature of +8C to +14C and is suited to the storage of fruits and vegetables, as well as keeping drinks cooled. Colder is the "cold storage compartment" or "fresh compartment" at about 0C, intended for the temporary storage of meat, cold cuts, mushrooms and wild fruit. Multi-zone units therefore usually consume more power then pure refrigerators, refrigerators with a (***/*) compartment or refrigerator-freezer combinations. Whether these have advantages in the household depends on the possibilities for storage, as well as on shopping and cooking habits. In addition to freezer and special compartments, there are also ice compartments and star compartments with from one to four stars. Ice compartments are often not exactly defined. If these have no (*) designation, one should assume that they are in the temperature region of 0C, that is not suited top either the storage or the freezing of foodstuffs intended for deep freezing. (*) compartments with -6C inner temperature and (**) compartments with -12C inner temperature are suited only to the short-term storage of already frozen deep freeze goods before using within a time of one to a few days. One can not freeze fresh foods in this compartment. Whoever wishes to store frozen goods longer requires at least a (***) compartment with -18C or preferably a (*/***) compartment with -18C. The difference between (***) and (*/***) compartments has to do with their freezing behavior. Only (*/***) compartments can coll fresh goods fast enough so that other already frozen goods in storage do not thaw in the meantime and spoil. Whoever wishes to freeze fresh foodstuffs therefore requires a (*/***) compartment. Units with a (*/***) compartment are in fact usually more economical than units with a (**) or a (***) compartment.

Defrosting, No-frost or Low-frost
Ice forms in refrigerators and freezers when humid air flows in on opening the door or when foodstuffs are stored. A small amount of ice is not a problem, but a large amount of ice increases power consumption when it covers the surface of the inner heat exchanger or hinders closing the door. Defrosting is then necessary.
No-frost units have a small blower for the permanent circulation of an air current to prevent the formation of ice within the unit. This may be convenient, however the fan requires 10 to 30 percent more power. On the other hand, no power is consumed for cooling down the unit again, as is otherwise required following manual defrosting. Low-frost units or stop-frost units reduce the intake of air from the outside and the expulsion of air from within during the temperature change, without additional power consumption. The frequency of defrosting can be reduced by loading and unloading as quickly as possible, preferably once over a longer time than opening the door several times in rapid succession. Especially with freezers, one should ensure that no ice forms on the door seals. If these do not seal correctly due to the presence of ice, ice then forms faster in the rest of the unit.

The cooling circuits and insulating materials of older refrigerators and freezers usually contain fluorinated-chlorinated carbohydrates (CFCs) or fluorinated carbohydrates (FCs), which are very damaging to the environment. In order to prevent the release of these substances to the atmosphere, old units may not be disposed of as bulky refuse or placed at the edge of the curb, but must be correctly disposed of. This entails the removal by suction of the harmful substances, eliminating potential environmental damage. Your town or city administration and your disposal company can tell you who is able to properly dispose of old units. Today, the use of CFCs in new units is forbidden, and FCs are fortunately only rarely used. If you want to contribute to environmental protection, look for the property "CFC and FC - free" at the time of purchase.

qualities should be given a higher priority. Differentiated quality criteria for environmentally sustainable washing machines have recently been formulated in a study of the Ecological Institute or EcoTopTen. The list of criteria and the research report can be found under the address www.ecotopten.de, under Downloads. Also worth reading are the Stiftung Warentest (in the September edition) and ko-Test (consumer advice magazines) test reports about washing machines. For the future, for all washing machines it would be desirable to declare the rinsing effectiveness and the consumption values for the most frequently used 30C and 40C washing programs. The tables differentiate between 4.5 kg, 5 kg and XXL units with 5.5 kg or 6 kg loads. The 4.5 kg units often have a higher consumption level than the 5 kg models and are therefore not recommended. Whether large 5.5 kg or 6 kg XXL units are meaningful must be carefully considered, since these are often more economical only when fully loaded.

(1) Tabletop unit, can be installed as under-table unit, 82 cm high after removing working plate. (2) Consumption data for pre-spin drying of laundry at 800 rpm. (3) 1 cm3 gas assumed to be 9.35 kWh. This value can vary slightly from one gas supply region to another. (4) For integration as an under-table unit, furniture front must be provided.
The energy consumption for drying depends on the efficiency of water removal by spin drying, the drying technique, the unit size, and the efficiency of the respective drier. While in earlier times nearly all consumption data applies to pre-spin drying of laundry at 800 rpm, in 2006/2007 as a result of new regulations for measurements there are unfortunately three parallel consumption values, for pre-spin drying of laundry at 800 rpm, 1000 rpm and 1400 rpm. This can cause confusion. Around the middle of 2007, the data will probably be uniform once again. Since the differences in consumption are very different according to the speed of the spin-dry process, households with large amounts of colored and hightemperature laundry should use washing machines with at least 1200 rpm, preferably 1400 rpm.

Gas driers, Heat pump driers and Drier cabinets
From the technical standpoint, gas-driven and heat pump driers consume the least primary energy and have the lowest operating costs. At the same time, the purchase prices for these units are higher. Among conventional driers, air-vented driers are more economical than air condensation driers. For operation in a heated apartment, however, it is necessary to consider that air-vented driers blow warm air out of the room in winter requesting additional heating. Still more economical than all drum driers are drier cabinets with a built-in fan that blows only cold air around the laundry hanging in it for 12-20 hours. Such units are available from NIMO and TPS (see page 16 for addresses). Using these however with hot air, with heating, results in considerably greater consumption of power than with comparable drum driers. Remember that the least amount of electricity is consumed by a wash line.

Hot water connection for washing machines and dishwashers
Washing machines and dishwashers require the greatest part of the power consumed for heating the water. For washing machines, part of this can be saved by using units having an additional hot water connection in addition to the cold water connection (see page 11, above) or retrofitting with a hot water mixing unit (see page 15, below). Most dishwashers can be directly connected to hot water (see data in the column "Hot water connection"). Not recommended for hot water connections are dishwashers with internal heat recovery, e.g. many 45 cm models of Siemens-Bosch. since this technology is designed for use with a cold water connection only. The use of hot water is recommended when this is taken from solar systems, district heating, modern central heating, or suitable gas flow heaters. The feeder lines should be short and well insulated, and the hot water kept at a temperature not above 60C. For washing machines, not more than two liters, and for dishwashers not more than one liter, cold water should flow from the faucet before hot water begins flowing. Whether a model is technically designed for a hot water connection should be clarified or read from the user manual. Older models may have supply hoses, water valves and automatic controls that are not suitable for connection to hot water.

(1, 2, 3) See page 14
Many washing machines having only a cold water connection can be supplied with hot water for hot water by installing a cut-in unit before the feeder hose usage with washing machines for mixing hot and cold water to give the required temperature. This saves on electricity and reduces environmental loading. It must be clarified in advance whether the feeder hose, solenoid valve, switching program and possibly other components of the washing machine are compatible with this. Manufacturers of such cut-in units are: - Martin Elektrotechnik GmbH, Buchwaldstr. 53, 97769 Bad Brckenau (www.ms1002.de) - OLFS & Ringen, Richtweg, 27412 Kirchtimke (www.olfs-ringen.de) - Schwab & Wilms Energie-Beratungs-Service, 60596 Frankfurt, Tiroler Str. 61 - Stemberg Solar- und Gebudetechnik, 32791 Lage, Im Seelenkamp 7 (www.Stemberg-Solar.de)
