💰 USAGE COSTS & RUNNING EXPENSES

📊 Annual Running Cost Calculation

Understanding the true cost of pool pump operation helps you make informed decisions and budget effectively. Here’s a realistic cost analysis for the Argonaut AV75-2DN-S:

🏊 Seasonal Pool Usage Scenario:

• Power consumption: 0.60 kW (P1 input power)
• Typical usage: 8 hours/day during swimming season
• Swimming season: 180 days (May through October)
• Total annual runtime: 8 hours × 180 days = 1,440 hours/year
• UK energy rate: £0.24 per kWh (November 2024 average)

✅ Annual Running Cost: 0.60 kW × 1,440 hours × £0.24 = £207.36 per year

💷 Daily Operating Cost (During Season): 0.60 kW × 8 hours × £0.24 = £1.15 per day

---

💡 COST SAVINGS EXAMPLES

📍 Scenario 1: Upgrading from an Older 0.75 HP Pump

Many older pool pumps consume significantly more energy due to outdated motor technology and lower efficiency ratings.

❌ Old 0.75 HP pump (typical P1: 0.85 kW):

• Annual cost: 0.85 kW × 1,440 hours × £0.24 = £294.00

✅ New Argonaut AV75-2DN-S (P1: 0.60 kW):

• Annual cost: 0.60 kW × 1,440 hours × £0.24 = £207.36

💰 Annual Savings: £86.64 📈 3-Year Savings: £259.92 ⏱ Payback Period: Approximately 2-3 years (depending on pump price)

---

📍 Scenario 2: Year-Round Heated Pool/Spa Operation

For heated pools or spas requiring continuous circulation:

• Extended usage: 6 hours/day, 365 days/year
• Total annual runtime: 6 hours × 365 days = 2,190 hours/year

✅ Argonaut AV75-2DN-S Annual Cost: 0.60 kW × 2,190 hours × £0.24 = £315.36

❌ Compared to a less efficient 0.75 HP competitor (P1: 0.82 kW):

• Annual cost: 0.82 kW × 2,190 hours × £0.24 = £430.90

💰 Annual Savings: £115.54 💷 5-Year Savings: £577.70

---

📍 Scenario 3: Reducing Runtime with Efficient Filtration

The Argonaut’s high flow rate (136 LPM) means you can achieve effective filtration in shorter periods compared to lower-flow pumps.

❌ Lower-flow pump (100 LPM): Requires 10 hours/day for complete turnover ✅ Argonaut AV75-2DN-S (136 LPM): Achieves turnover in 7.5 hours/day

Energy Savings from Reduced Runtime:

• Old pump: 0.65 kW × 10 hours × 180 days × £0.24 = £280.80/year
• Argonaut: 0.60 kW × 7.5 hours × 180 days × £0.24 = £194.40/year

💸 Annual Savings: £86.40 ⚡ Added benefit: Less wear on pump components, extending service life

🎯 REAL WORLD EXAMPLES & APPLICATIONS

🏊‍♂️ Medium-Sized Residential Swimming Pools Ideal for pools ranging from 30,000 to 50,000 litres (approximately 6m × 4m × 1.5m depth). The 0.5 HP motor provides sufficient circulation for effective filtration without excessive energy consumption. Typical installation includes connection to a sand or cartridge filter with automated timer control for 8-hour daily cycles during swimming season.

🛁 Hot Tubs & Spa Systems Perfect for medium-capacity spas (1,500-3,000 litres) requiring continuous water circulation for heating and sanitization. The pump’s chemical-resistant construction handles spa chemicals including bromine and chlorine, while the quiet operation (60-62 dB) won’t disturb relaxation. Self-priming capability simplifies installation in spa cabinets below water level.

🌊 Koi Ponds & Water Features Excellent choice for decorative ponds and water features requiring reliable circulation. The robust strainer basket captures leaves and debris, while the corrosion-resistant components withstand continuous outdoor exposure. Self-priming function enables installation at various heights relative to water level, providing design flexibility.

🔄 Replacement & Upgrade Projects Common replacement for aging Sta-Rite, Hayward, or Pentair pumps in the 0.5-0.75 HP range. Standard 2¾” BSP connections ensure compatibility with most existing plumbing systems. The compact dimensions (164mm × 533mm) fit easily into existing pump housings, making retrofit installations straightforward.

🏢 Light Commercial Applications Suitable for small commercial installations including hotel spas, gym pools, and guest house water features. TÜV certification and IPX5 motor protection meet commercial safety requirements, while the maintenance-friendly design minimizes service costs and downtime.
