Energy and environment tips

Here you can find tips on how to save energy when baking and 

roasting in the oven and when cooking on the hob, and how to 

dispose of your appliance properly.

Saving energy with your oven

■

Only preheat the oven if this is specified in the recipe or in 

the operating instruction tables.

■

Use dark, black lacquered or enamelled baking tins. They 

absorb the heat particularly well.

■

Open the oven door as infrequently as possible while 

cooking, baking or roasting.

■

It is best to bake more than one cake, one after the other. 

The oven is still warm. This reduces the baking time for the 

second cake. You can also place two loaf tins next to each 

other.

■

For longer cooking times, you can switch the oven off 

10 minutes before the end of the cooking time and use the 

residual heat to finish cooking.

Saving energy with the hob

■

Use pots and pans with thick, even bases. Uneven bases 

increase energy consumption.

■

The diameter of pan bases should be the same size as the 

hotplate. In particular, small saucepans on the hotplate cause 

energy losses. Note that cookware manufacturers often 

indicate the upper diameter of the saucepan. This is usually 

bigger than the diameter of the base of the pan.

■

Use a small saucepan for small quantities. A larger, less full 

saucepan requires a lot of energy.

■

Always place suitable lids on saucepans. When cooking 

without a lid, four times the energy is required.

■

Cook with only a little water. This will save energy. Vitamins 

and minerals in vegetables are preserved.

■

Switch to a lower heat setting in good time.

■

Use the residual heat. For longer cooking times, you can 

switch the hotplate off 5-10 minutes before the end of the 

cooking time.

E no.

FD no.
