Illustrative arithmetic only—the inputs are assumptions, not a savings forecast
4,000 kWh annual consumption • €0.30/kWh average rate
2,000 kWh heating × an illustrative 5% measured reduction × €0.30/kWh
4 kWh/week × 52 × (€0.30 peak − €0.15 off-peak)
20 W avoided × 16 hours/day × 365 × €0.30/kWh
This is not a forecast or guarantee. Replace every assumption with measured consumption, actual tariff spreads, equipment efficiency, and observed before/after data.
