Audited planning profile
This couple five-year profile applies a 2× editable baseline across 60 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. Agree on shared inputs and ownership before comparing the two-person result. Treat maintenance, replacement and compounding assumptions as material over five 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.
