🏊 Scenario 1: Seasonal Residential Pool (6 months operation)

• Daily runtime: 8 hours
• Operating season: 180 days (April – September)
• Annual running hours: 8 × 180 = 1,440 hours
• ✅ Annual cost: 1.55kW × 1,440h × £0.2635 = £588.10

♨️ Scenario 2: Year-Round Heated/Indoor Pool

• Daily runtime: 10 hours
• Operating period: 365 days
• Annual running hours: 10 × 365 = 3,650 hours
• ✅ Annual cost: 1.55kW × 3,650h × £0.2635 = £1,491.43

🏢 Scenario 3: Commercial Pool (Extended Hours)

• Daily runtime: 12 hours
• Operating period: 365 days
• Annual running hours: 12 × 365 = 4,380 hours
• ✅ Annual cost: 1.55kW × 4,380h × £0.2635 = £1,789.72
