Selection Criteria Coffee Machines

Methodology

Scope

Topten.eu – Best Products of Europe – presents the best fully automatic coffee machines and portioned machines for capsules and pads. Not considered are filter coffee machines, machines with piston lever, combi-machines and (commercial) appliances with a permanent water supply.

Technical Criteria

In order to be displayed on topten.info, coffee machines must meet the same technical criteria as required by the Blue Angel. For its new label for coffee machines The Blue Angel has overtaken the energetical criteria developped by Topten (see RAL-UZ 136). The criteria are:
  • Auto-power-down function switching off the permanent heating of the water after a certain time lag to standby or off
  • Time lag of the auto-power-down, factory setting:
    • Portioned machines: max. 15 minutes
    • Fully automatic machines: max. 1 hours
  • Time lag of the auto-power-down, programmable by the users
    • Portioned machines: max. 30 minutes
    • Fully automatic machines: max. 4 hours
  • Power consumption in standby (or sleep) following the auto-power-down: max.1 W
  • Electricity consumption for ready mode:
    • max. 35 Wh: fully automatic, piston hand-operated machines
    • max. 30 Wh: portioned machines
    Machines with flow-type heater do not consume heating energy in "ready" mode. Therefore they comply with the ready mode criterion although it can not be measured according to the measurement method.
  • maximum annual consumption limit
    • 45 kWh for fully automatic
    • 35 kWh for portioned machines
  • Available in at least one European country
  • Relevant values have to be provided by the suppliers. Suppliers who are not able to provide these values cannot claim to have their appliances displayed on topten.info. All declarations can be verified by random measurements.

    Data sources

    Order of presentation

    The products are ranked according to their electricity costs during 10 years. The order of presentation can be changed by clicking on the headings of the tables.

    Glossary

    Brand, Model, Similar Models

    The brand names and model names are on the list. Products of similar construction and identical technical values are displayed only once. Similar models’ names are listed under ‘similar models’.

    Pump Pressure (bar)

    Preparing a "real" espresso requires at least around 8 bars, while coffee machines that work with lower pressure produce more a kind of filter coffee.
    Electricity Costs
    Assumptions:
    • Product’s lifetime: 10 years
    • Yearly electricity consumption according to the typical usage pattern described in the Euro-Topten-Measuring Method and Calculation Formula for the Electricity Consumption of Coffee Machines for Household Use.
    • Tarif of electricity: 0.15 €/kWh, (this value should be understood as order of magnitude as there can be large differences depending on country or electrical utility).

    Energy

    Energy consumed during a year according to the Euro-Topten-Measuring Method and Calculation Formula for the Electricity Consumption of Coffee Machines for Household Use.
    The following typical usage pattern is assumed:
    • The coffee machine is being used in the factory setting.
    • Twice a day, 3 cups of coffee are produced within 1 hour (coffee period).
    • 2’190 cups are being produced per year, using 20 kWh (the number of cups has been identified in a representative survey in Switzerland in 2002).
    • Time in the ready mode (keeping hot) depends on the auto-power-down delay. Standby is assumed for the rest of the time in a year.

    Standby Mode

    Power consumption in standby mode (watts). When a machine is in standby mode, the water heating elements are inactive. Accordingly, coffee can only be produced after the heating element has been heated up to the temperature needed. The machine’s control unit is supplied with electricity, allowing for instance a mode indication to be visible or a time-controlled activation function to operate in the background. Some coffee machines have two different standby values, e.g. before and after the auto-power-down.

    Switch-off Delay

    Delay in minutes to activation of the switch off (auto-power-down) after the machine has last been active or manipulated (factory setting).

    Countries available

    Countries in which a product is available according to producers delarations; country codes according to ISO.
    EU = available throughout the European Union
    On demand = producers could not indicate the availability and consumers have to ask on their own
