Audited planning profile
This conservative weekly profile applies a 1.2× editable baseline across 7 model periods to the heating appliance use breakeven model.
Compare the break-even period with the time you realistically expect to keep or use the option. Use this profile when protecting downside matters more than optimizing the headline result. Account for weekday/weekend variation and incomplete weeks.
Local tariffs, taxes, seasonal efficiency and regulated charges are not inferred automatically.
