Audited planning profile
This shared ten-year profile applies a 3× editable baseline across 120 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. Define a consistent allocation rule so shared usage is not counted twice. Use a wide uncertainty range; small recurring assumption errors compound substantially over ten years.
Local tariffs, taxes, seasonal efficiency and regulated charges are not inferred automatically.
Check a recent bill, device specification and current tariff before committing to a purchase or retrofit.
