💰 Usage Costs & Running Expenses

Understanding your running costs helps you budget effectively and appreciate the value of an energy-efficient pump.

📊 Annual Running Cost Calculation

Motor Power Consumption: 0.37 kW (approximately 0.5 HP)

Current UK Energy Rates (Q4 2025): Based on the Ofgem Energy Price Cap effective 1 October – 31 December 2025, the average electricity rate is £0.2635 per kWh for households paying by direct debit.

🏊 Seasonal Pool Operation (6 Months)

Typical residential usage: 8 hours per day for 180 days (April–September)

• Daily running hours: 8 hours
• Swimming season: 180 days
• Annual operating hours: 8 × 180 = 1,440 hours
• Energy consumption: 0.37 kW × 1,440 hours = 532.8 kWh
• ✅ Annual running cost: 532.8 × £0.2635 = £140.39

♨️ Year-Round Spa/Hot Tub Circulation

Continuous low-speed circulation: 4 hours per day for 365 days

• Daily running hours: 4 hours
• Annual operating hours: 4 × 365 = 1,460 hours
• Energy consumption: 0.37 kW × 1,460 hours = 540.2 kWh
• ✅ Annual running cost: 540.2 × £0.2635 = £142.34

🏢 Extended Commercial Use (10 Hours Daily)

Commercial pool or busy residential: 10 hours per day for 200 days

• Daily running hours: 10 hours
• Operating season: 200 days
• Annual operating hours: 10 × 200 = 2,000 hours
• Energy consumption: 0.37 kW × 2,000 hours = 740 kWh
• ✅ Annual running cost: 740 × £0.2635 = £195.00

💡 Cost Savings Examples

Upgrading from an older, less efficient pump or switching from a higher-powered unit can deliver significant savings over time.

📍 Scenario 1: Upgrading from an Older 0.75 HP Pump

Many older pool pumps were oversized for residential pools, consuming more energy than necessary.

Comparison with typical 0.75 HP older pump (0.55 kW):

Assuming 1,440 hours seasonal operation:

• ❌ Old 0.75 HP pump: 0.55 kW × 1,440 hours × £0.2635 = £208.76/year
• ✅ Malawi Adapt Pro ST 0.5HP: 0.37 kW × 1,440 hours × £0.2635 = £140.39/year
• 💰 Annual saving: £68.37
• 📈 5-year saving: £341.85
• ⏱️ Payback period: If pump costs £300, payback achieved in approximately 4.4 years through energy savings alone

📍 Scenario 2: Replacing a Failed Sta-Rite 5P2R

The Malawi Adapt Pro ST is designed as a direct replacement for Sta-Rite 5P2R pumps, offering comparable performance with modern efficiency.

Benefits of like-for-like replacement:

• ✅ No plumbing modifications required
• ✅ Standard 1½” BSP connections
• ✅ Identical mounting footprint (254mm hole spacing)
• ✅ Same flow characteristics for your existing filtration system
• 💰 Installation savings: £150-£300 versus non-compatible pump requiring pipe modifications

📍 Scenario 3: Running Cost Comparison – Monthly Breakdown

For typical 8-hour daily seasonal operation:

Month	Hours	kWh Used	✅ Monthly Cost
April	240	88.8	£23.40
May	248	91.8	£24.19
June	240	88.8	£23.40
July	248	91.8	£24.19
August	248	91.8	£24.19
September	216	79.9	£21.05
Total	1,440	532.9	£140.42

🎯 Real World Examples & Applications
