Audited planning profile
This couple daily profile applies a 2× editable baseline across 1 model period to the home hot water 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. Use a typical day and separately test peak or exceptional days.
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.
