💰 Usage Costs & Running Expenses

One of the PPG Pump 6’s greatest advantages is its exceptionally low running costs. At just 0.37kW, this pump delivers meaningful water circulation while consuming a fraction of the electricity required by larger models.

📊 Annual Running Cost Calculation

Base Parameters:

• Power consumption: 0.37 kW
• UK electricity rate: £0.2635 per kWh (Ofgem Q4 2025 price cap)

🛁 Scenario 1: Hot Tub Filtration (Year-Round)

Typical residential hot tub with daily filtration cycles:

• Daily usage: 6 hours filtration
• Operating days: 365 days
• Annual hours: 6 × 365 = 2,190 hours

Calculation:

• Energy consumption: 0.37 kW × 2,190 hours = 810.3 kWh
• ✅ Annual cost: 810.3 × £0.2635 = £213.51

💰 That’s just £17.79 per month for year-round hot tub filtration!

🏊 Scenario 2: Seasonal Small Pool Use (6 Months)

Small above-ground or plunge pool during summer season:

• Daily usage: 8 hours filtration
• Season length: 180 days (April–September)
• Annual hours: 8 × 180 = 1,440 hours

Calculation:

• Energy consumption: 0.37 kW × 1,440 hours = 532.8 kWh
• ✅ Annual cost: 532.8 × £0.2635 = £140.39

🌊 Scenario 3: Water Feature/Continuous Circulation

Garden water feature or continuous low-flow circulation:

• Daily usage: 10 hours
• Operating days: 200 days (spring through autumn)
• Annual hours: 10 × 200 = 2,000 hours

Calculation:

• Energy consumption: 0.37 kW × 2,000 hours = 740 kWh
• ✅ Annual cost: 740 × £0.2635 = £195.00

♨️ Scenario 4: Extended Hot Tub Use (Heavy User)

Frequent hot tub users running longer filtration cycles:

• Daily usage: 10 hours
• Operating days: 365 days
• Annual hours: 10 × 365 = 3,650 hours

Calculation:

• Energy consumption: 0.37 kW × 3,650 hours = 1,350.5 kWh
• ✅ Annual cost: 1,350.5 × £0.2635 = £355.86

🎯 Real World Examples & Applications

🛁 Hot Tubs & Compact Spas

The PPG Pump 6 is perfectly sized for standard residential hot tubs requiring reliable filtration and circulation. The 6 m³/h flow rate provides adequate turnover for most domestic spas while the whisper-quiet operation ensures your relaxation isn’t disturbed by pump noise. The Viton seals and salt compatibility make it ideal for hot tubs using bromine, chlorine, or salt-based sanitisation systems.

✅ PPG Pump 6 (0.37kW – correctly sized):

• Power: 0.37 kW
• Annual hours: 2,190
• Energy: 0.37 × 2,190 = 810.3 kWh
• ✅ Annual cost: 810.3 × £0.2635 = £213.51

💰 Annual Saving: £219.29 📈 5-Year Saving: £1,096.45

📍 Scenario: Reduced Maintenance & Longevity

❌ Budget Pump Typical Costs:

• Average lifespan: 2-4 years
• Replacement cost: £150-250 every 2-4 years
• Seal failures: Common within 1-2 years
• Warranty: Typically 1 year only
