Audited planning profile
This freelance one-time profile applies a 1.5× editable baseline across 1 model period to the heating appliance use buffer model.
Use the buffered result for planning and the unbuffered result as the transparent baseline. Separate personal and business costs, unpaid time and tax reserves. Include setup, transaction and end-of-use costs in a one-time decision.
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.
