A household appliance for drying a laundry item, the household appliance comprising:

• a treatment chamber to receive the laundry item;
• a closed process air circuit to feed process air through the treatment chamber, the closed process air circuit comprising:
• a blower to move the process air;
• a condenser to condense out moisture carried in the process air;
• a heater to heat the process air;
• a first measurement device to determine a temperature of the process air when the process air enters the treatment chamber and to provide a first measurement signal;
• and
• a controller to control the blower and the heater as a function of the first measurement signal;
• an analyzer associated with the controller, the analyzer to determine an energy requirement to dry the laundry item prior to initiating a drying process for the laundry item;
• an integrator to determine an energy input to the process air via the heater up to a respective measurement time;
• and
• a comparator to compare the energy input with the energy requirement and to end the drying process when the energy input matches the energy requirement.
