Audited planning profile

This lean three-year profile applies a 0.75× editable baseline across 36 model periods to the home hot water projection model.

USE THIS PROFILE TO

Estimate recurring household operating cost and compare practical energy-use choices.

DECISION RULE

Review both the projected result and the assumed recurring change before relying on the forecast. Treat the lean scale as a lower-bound plan and test whether essential fixed costs still fit. Run an adverse case for inflation, downtime and changing demand over three years.

NOT INCLUDED

Local tariffs, taxes, seasonal efficiency and regulated charges are not inferred automatically.

VERIFY BEFORE ACTING

Check a recent bill, device specification and current tariff before committing to a purchase or retrofit.
