The Best Energy Saving Tips for the Refrigerator


In many households, the refrigerator often has to do its work all year round. Consumers who use their device as energy-efficiently as possible can significantly reduce their electricity bills.

The refrigerator is one of the household appliances in addition to a washing machine. Especially older devices often consume 300 kilowatt hours of electricity and more per year - the equivalent of electricity costs of around 100 euros. It will be even more expensive if measures to save energy are disregarded and the devices are operated incorrectly.

Consistently dispose of old devices

New refrigerators typically consume 25 to 50 percent less electricity than they do comparable old appliances. However, one of the major energy-related problems in the household is when the aged kitchen veteran is given a second life as a drinks cooler in the basement or in the garage. Instead of one device, there are now two - so you can not save electricity.

It's all about temperature and location

It often happens that the temperature of the refrigerators is not set correctly is. A rule of thumb is that around six percent more electricity is needed per degree of additional cooling power. Experts estimate seven degrees in the refrigerator and -18 degrees in the freezer. For a model with 250 kilowatt hours of electricity per year, each one-degree drop in temperature leads to additional costs of four to five euros per year.

In addition to the temperature, the location of the refrigerator should be selected correctly. Just places next to heat sources such as stove, washing machine or dishwasher and radiators are to be avoided. Optimal is a free, shady footprint without direct sunlight. Important is also enough free space to the rear. If the ventilation openings are delivered or covered, the waste heat can no longer flow unhindered. The result: The cooling unit heats up and has to spend about 10 percent more power for cooling.

No "No Frost" yet? Then regular defrosting is mandatory!

Most older devices do not yet have no-frost techniques. A regular defrosting of the freezer compartment is obligatory here. With iced-up freezers, the energy efficiency of the refrigerator drops and the power requirement increases significantly. In particular, the holiday season is a great way to pull the plug and to check the device carefully. In particular, the rubber seals on the doors should be regularly checked and replaced if they are brittle or defective.

Full Refrigerators Use Less Energy

A full refrigerator consumes less energy than an empty one. Air is a good conductor of heat compared to food. If the door of an empty refrigerator is opened, there is a faster heat exchange, in the wake of which more energy must be expended to reach the set temperature again. Too long opening the refrigerator door is poison for the energy balance. Therefore, the refrigerator door and freezer door should never be left open unnecessarily.

Another way to reduce energy consumption is to keep food from the freezer thawed in the refrigerator rather than at room temperature. The frozen food releases cold to the appliance and the cooling demand drops. On the other hand, of course, only foods cooled to room temperature are in the fridge, as the cooling down of heated food is very energy-intensive.

Energy efficiency classes: Who says "A" must also say "A +++"

If you decide to buy a new fridge, you should pay close attention to the energy-saving label. Originally energy efficiency class A was considered the best category, today the scale ranges from A +++. According to the Federal Environment Agency, an efficient new appliance can save up to 60% of the electricity costs compared to a ten-year-old model.
