Frequently Asked Questions

Multiply the annual energy consumption (in kWh/a) found on the energy label by your local electricity price (per kWh). Since a freezer runs 24/7, even small differences in efficiency lead to large savings over time.

Older freezers (10+ years) often consume 2-3 times more electricity than modern A-rated models. In many cases, the electricity savings can pay back the cost of a new freezer within 5 to 7 years.

NoFrost prevents ice from building up on the cooling coils. While these machines use slightly more power to run the fan, they stay efficient. A traditional freezer's energy consumption increases by up to 30%% if just 5mm of ice builds up.

Chest freezers are generally more efficient because cold air stays inside when you open the top lid. Upright freezers lose cold air faster when opened but offer much better organization and take up less floor space.

Keep the freezer full (use water bottles if empty) to maintain thermal mass, ensure the door seals are tight, and place the appliance in a cool, well-ventilated spot away from heat sources like ovens or direct sunlight.

Multiply the annual energy consumption (in kWh/a) by your local electricity price (per kWh). This calculator also factors in initial purchase and potential repair costs.

Yes, especially for appliances that run 24/7. An A-rated freezer can save significant costs over its 10-15 year lifespan compared to an older or less efficient model.

Detailed Methodology & Calculation Logic

Energy Consumption Logic

Unlike other appliances, freezers run 24/7. The calculator uses the standard annual kWh rating (typically found on the energy label).

  • Annual Energy Cost: Calculated by multiplying the device's annual kWh rating by your local electricity price per unit.
  • Constant Load: The model assumes a steady-state operation, though actual consumption can vary slightly based on ambient temperature and door openings.
Total Cost of Ownership (TCO)

We project the cumulative expense of operating the freezer over its typical 15-year lifespan.

  • Cumulative Costs: Includes the initial purchase price, annual electricity, and estimated long-term maintenance.
  • Guarantee & Repairs: Includes periodic repair costs (e.g., every 5 years) that are factored in once the manufacturer's guarantee period expires.
