Buying household appliances online: A guide to choosing the right products

Anyone looking to buy household appliances online will quickly find a wide range of kitchen appliances, cleaning equipment and products designed to create a more comfortable indoor climate. However, price alone says little about whether an appliance is suitable for your home, electrical connection and daily usage habits. What really matters is clear technical information, suitable dimensions and a realistic view of maintenance and ongoing costs.

Common pitfalls when buying household appliances online

1. Performance figures without the right usage context

High wattage, bar or pascal values may seem convincing at first. However, they do not automatically indicate how suitable an appliance is for everyday use. With a vacuum cleaner, brush design, filter maintenance, battery life and cable length also matter. With an espresso machine, grind size, controls and water-tank capacity all affect how easy it is to use.

So make sure you check which measurement is actually relevant and whether it suits the size of your home and your household.

2. Dimensions and installation type are underestimated

A fridge with the right width may still be unsuitable because of the door hinge, depth or required ventilation clearance. With a dishwasher, the niche height, appliance width, water connection and door-panel fixing all need to match. A cooker hood also requires the specified clearance above the hob and, where applicable, an extraction duct.

Before buying, measure the niche, door-opening area and connections, then compare them with the technical data sheet.

3. Energy efficiency is judged only by the letter rating

The EU energy label ranges from A to G. However, actual consumption is also important for running costs, for example kWh per 100 wash cycles or kWh per year. Despite having the same energy rating, a larger appliance may use considerably more electricity than a compact model.

Always consider the energy rating, consumption figure, capacity and your actual usage together.

Key parameters at a glance

Energy consumption and running costs

For energy-efficient household appliances, the stated consumption should be considered in relation to the appliance’s size. A dishwasher using 75 kWh per 100 cycles requires less energy per standard cycle than a model using 92 kWh per 100 cycles. For a rough cost estimate, multiply the consumption by your electricity tariff and the expected number of uses.

Small appliances can add up too: a 120-watt heated blanket, an air purifier using 21 or 25 watts and a 550-watt vacuum cleaner will have very different effects on electricity consumption depending on how long they are used.

Noise levels and your living situation

Noise is generally specified in dB or dB(A). Dishwasher noise levels of 44 to 48 dB may be important in open-plan kitchens. A fridge rated at 39 dB or an appliance rated at 40 dB may be perceived differently in a kitchen-diner than in a separate utility room.

Bear in mind that noise levels can depend on the programme, surface and installation location. For bedrooms and home offices, a night mode and timer function may also be relevant.

Maintenance, filters and connections

An appliance with a washable filter can reduce the need to buy replacement filter inserts regularly, provided the filter is designed to be washed according to the instructions. With air purifiers, check the filter class, replacement interval and availability of spare parts. For cooker hoods, check whether the grease filter is dishwasher-safe and whether a carbon filter is required for recirculation mode.

The manufacturer’s installation instructions apply to water and electrical connections. Built-in appliances such as dishwashers and fully integrated fridges should be connected by a qualified professional.

Pre-purchase checklist

  • Check the dimensions: Compare width, height, depth, door hinge position and ventilation clearances.
  • Calculate energy consumption: Consider not only the energy rating, but also the kWh figure and frequency of use.
  • Assess the noise level: This is particularly important for open-plan kitchens, small homes and appliances used in bedrooms.
  • Check consumables: Filters, carbon filters, vacuum bags, descaling agents and replacement brushes.
  • Consider safety: CE marking, instructions in German, EU responsible person and professional installation.
  • Assess the maintenance requirements realistically: Removable parts and dishwasher-safe components can make regular cleaning easier.

Frequently asked questions about buying household appliances online

Which household appliances use the most electricity?

Consumption depends on both power and operating time. Fridges and freezers run continuously, while vacuum cleaners, espresso machines and heated blankets are generally used for shorter periods. For large appliances, compare annual consumption; for smaller appliances, compare the wattage with the expected duration of use.

How long do household electrical appliances last?

Lifespan depends on the design, usage, maintenance and availability of spare parts. Regularly cleaning filters, seals and collection containers can help maintain performance. Before buying a fridge, dishwasher or cooker hood, check the maintenance instructions and warranty conditions.

What do I need to consider when installing a dishwasher?

Measure the standard width and niche height, and check the water and electrical connections as well as the hose lengths. With fully integrated appliances, the furniture door must also be compatible. The connection should be carried out in accordance with the instructions and local safety requirements.
