From watts to annual cost

Automatic modes vary power, so calculate more than one scenario when possible.

Key points

Turn operating power, daily runtime and tariff into comparable energy scenarios.

How to use this in practice

Measure the room and record the operating conditions first. Compare values at the same speed and under similar conditions. A marketed room area is not universal; volume and target airflow are more transparent.

Limitations

Outdoor conditions, building leakage, open doors, ongoing sources and furniture layout can materially change performance.
