How Green is Thermomix?

Thermomix is an ultra energy-efficient kitchen appliance.Thermomix Energy Efficient Kitchen Appliance

It’s not only Thermomix users who know this fact — we’re heard that the offices of Hydro Tasmania use Thermomix as a shining example of energy-efficient cooking because of its many unique attributes. (Now if we could just get our local BC Hydro to pay attention to the Bimby Phenomenon…)

It took 120 engineers and years of development time to arrive at the simply sophisticated   Thermomix TM31 model we enjoy today.  (Remember too, this is a prize-winning design.)  The Vorwerk company in Germany is very serious about maintaining the highest standard of efficiency in all apects of use and performance. Heating of the TM31 is constantly and precisely monitored and controlled throughout the entire cooking process. Due to the multi-patented advanced heating system of the TM31, heat energy is able to be delivered and applied directly to the food with minimal thermal loss. This is due to the the localised heating element being integrated into the base of the Thermomix bowl, made of surgical stainless steel.

Energy efficiency and conservation of resources

  • Patented technology  generates even heat distribution with adaptable power density. Low thermal mass of the heating system ensures quick reaction time, thus preventing overcooking after heating stops.
  • According to Thermomix head office: The TM31 consumes only the amount of energy that is needed to reach and keep the preset temperature level. A stovetop, for example, keeps on supplying energy even when the water is already at boiling point unless you reduce the setting manually. The TM31 detects when the preset value is reached and reduces the heating power automatically thus saving energy.
  • Processing and cooking times for most food are greatly reduced and this saves both time and energy. Constant stirring of ingredients while cooking distributes heat very efficiently and evenly to reduce the cooking time required.
  • The extended heating element at the bottom of the mixing bowl allows for much more efficient preparation of small quantities. This energy conserving attribute is particularly noticeable when cooking for one or two people only.
  • The ability to control temperatures accurately within a concentrated area to allow steam-cooking above, while direct-cooking takes place simultaneously below makes for a doubling of results from a single energy source.
  • TMX uses about 500W for cold preparations and 1000W for heat whereas a normal stove top is 1500-2000W

Environmental benefits

  • According to Thermomix head office: The reluctance motor and advance heating system in the TM bowl work together to minimize the time required to cook foods. Heat is controlled at a constant temperature and with the sealed lid there is less energy escape.
  • Using only one pot also reduces requirement for multiple pots and pans on the stove and in the kitchen. Less storage space is needed.
  • Using fewer pots and pans also means less dishwashing is needed. This saves time and saves water! Thermomix uses about 600ml of water to ‘wash itself’ followed by a quick rinse.
  • Using fresh natural ingredients means purchasing less packaged foods, thereby reducing unnecessary packaging waste.

    I’m going to print this one. The energy-saving and the money-saving are, along with healthier eating, one of my best arguments for selling the Thermomix when people freak about the price.
    Your blog is most helpful Helene, thank you SO MUCH.
