How the maths works

Room volume × user-chosen watts per cubic metre. A rough sizing assumption; not a heat-loss survey.

Inputs are editable estimates. Financial results are scenarios, not forecasts or personalised advice. Absurd animal calculations are comparisons only.

One calculation leads to another.

That’s how you go from your electricity bill to a bath full of ducks.
