How to read this page
- Direct electric heating is simple and cheap to buy, but cost per day rises fast when runtime is high.
- A mini split usually needs more initial investment, yet its running cost can stay much lower over a season.
- Use this comparison to frame bill impact, not total payback, because installation and purchase price are outside this calculator.
