In the last two years, people have learned to think more about what appliances they buy for their homes. They exchange old washing machines, refrigerators and lighting for more economical ones, but they often do not realize that the biggest energy guzzlers have to be looked for completely elsewhere. They are surprisingly outdated circulation pumps that are safely hidden in the bowels of our homes. This is shown by the ranking of the five most uneconomical devices in European households, where outdated circulation pumps took first place.
Considering the constantly rising electricity prices, the topic of energy consumption is becoming more and more relevant not only for ecological reasons, but also for economic reasons. Here is the complete ranking of the 5 biggest energy guzzlers.
Old circulation pumps
These inconspicuous components, responsible for the circulation of heating water, can have a significant share in the total electricity consumption of the heating system. The problem with many of these pumps is that they run continuously, regardless of whether heat is needed or not. Older models are particularly inefficient and can use between 550 and 800 kWh per year. But technology has advanced. Modern highly efficient pumps are able to adapt their performance to current needs. This significantly reduces energy consumption.
The five biggest guzzlers of electricity:
Electric stove
Depending on the use and model, an electric stove consumes between 200 and 700 kWh per year. With regard to energy consumption, ceramic and induction cookers are often compared. While ceramic stoves heat using electric heating elements under the glass-ceramic plate, induction stoves use electromagnetic waves to heat the bottom of the container directly. This generally makes induction cookers more energy efficient and faster than ceramic ones. Consumption can be reduced, for example, by short preheating, using residual heat or cooking with a lid.

Freezer
Keeping food well below freezing at all times is not cheap. The compressor must work at high power, especially if the freezer is opened frequently or when warm food is being frozen. Depending on the model and size, consumption varies between 150 and 500 kWh per year. But there are modern technologies that, for example, prevent the formation of ice on the inner walls of the freezer. Without ice build-up, energy consumption remains consistently low because the freezer can work more efficiently.
Refrigerator
While modern refrigerators are significantly more energy efficient thanks to modern technology, they still need to run continuously. This leads to significant energy consumption. Depending on the size and the specific model, this can vary between 100 and 400 kWh per year. Consumption can be minimized by avoiding frequent and long door openings, proper food storage, not overfilling and setting the optimum temperature – usually between 5 and 7 °C.
Lighting
Proper lighting plays an important role in our everyday life. Today’s market is dominated by LED bulbs, which not only have a longer lifespan, but are also more energy efficient than conventional bulbs. Despite these advances, lighting in the average household still uses around 1 kWh per day, which is around 10% of total electricity use. Dimmable lights, motion detectors or consistently turning off lights when lighting is not needed can reduce energy consumption even more.
