Frequently asked questions
What formula does the Heat Pump Savings Calculator use?+
It uses saving = E·r·(1 − 1/COP). The steps section shows the formula with your actual numbers substituted, so you can follow (and verify) every stage of the calculation rather than trusting a black box.
What should I keep in mind when using this calculator?+
30 kWh of daily winter heating at ₹8/unit: ₹240 resistive vs ₹69 with a COP-3.5 heat pump — over ₹5000 saved per winter month. COP drops as outdoor temperature falls, so use a seasonal average; even COP 2.5 still pays for most climates.
Is the Heat Pump Savings Calculator free to use?+
Completely free, with no sign-up or limits. All computation happens client-side in your browser, so it is fast, private, and works even on slow connections once the page has loaded.
Can I use this for homework, teaching or exam prep?+
That is exactly what it is built for. The step-by-step working mirrors how solutions are presented in class, so you can check homework, build worked examples for teaching, or practise method recall before exams.
