💰 Usage Costs & Running Expenses

Understanding the true cost of pool pump ownership helps you make informed decisions. The Sta-Rite 5P2RC-1’s efficient 0.37kW motor delivers significant savings compared to older or oversized pumps.

📊 Annual Running Cost Calculation

Power consumption: 0.64 kW (input power) UK electricity rate: £0.2635 per kWh (Ofgem Price Cap, Q4 2025)

🏊 Scenario 1: Typical Residential Pool (Seasonal Use)

• Usage: 8 hours/day × 180 days (April–September)
• Total hours: 1,440 hours/year
• ✅ Annual running cost: 0.64 kW × 1,440 hrs × £0.2635 = £242.69

☀️ Scenario 2: Extended Season Pool

• Usage: 8 hours/day × 240 days (March–October)
• Total hours: 1,920 hours/year
• ✅ Annual running cost: 0.64 kW × 1,920 hrs × £0.2635 = £323.58

🔄 Scenario 3: Year-Round Indoor Pool

• Usage: 6 hours/day × 365 days
• Total hours: 2,190 hours/year
• ✅ Annual running cost: 0.64 kW × 2,190 hrs × £0.2635 = £369.38

⚡ Energy Efficiency Comparison

Pump Type	Power Input	Annual Cost (1,440 hrs)	vs. 5P2RC-1
✅ Sta-Rite 5P2RC-1	0.64 kW	£242.69	—
❌ Older 0.75HP pump	0.90 kW	£341.17	+£98.48/year
❌ Oversized 1.0HP pump	1.18 kW	£447.43	+£204.74/year
❌ Inefficient budget pump	0.85 kW	£322.22	+£79.53/year

💡 Key Insight: Correctly sizing your pump to your pool’s actual circulation needs prevents energy waste. An oversized pump doesn’t clean better – it simply costs more to run.

🎯 Real World Examples & Applications

🏊‍♂️ Residential Swimming Pools

The 7m³/hr flow rate is perfectly suited for domestic pools up to 40,000 litres, providing complete water turnover every 5-6 hours. Ideal for standard rectangular pools measuring approximately 8m × 4m with average depth of 1.4m. The self-priming design handles above-ground installations where the pump sits higher than the water level.

🛁 Hot Tub & Spa Circulation

For larger swim spas or hot tub circulation requirements, the 5P2RC-1 provides reliable continuous-duty performance. The thermal protection ensures safe operation even during extended spa sessions, while salt resistance accommodates modern saltwater sanitisation systems.

🌊 Water Features & Fountains

The high-head capability (up to 22.5m) makes this pump suitable for water features requiring significant lift, such as elevated fountains, cascades, and decorative waterfalls. The quiet motor operation is essential for features near living areas where noise would be intrusive.

🔄 Pool Upgrade & Replacement

As a direct replacement for ageing Sta-Rite pumps or equivalent 0.5HP models, the 5P2RC-1 offers improved efficiency and extended warranty coverage. Standard 1½” BSP connections ensure compatibility with existing pipework, minimising installation complexity and cost.

🏠 Small Commercial Installations

Suitable for small commercial applications such as holiday let pools, B&B guest pools, or rental property swimming pools where reliability and low maintenance are priorities. The clear strainer lid allows quick visual inspections without tools.

Typical repair cost	£150-200	Minimal (warranty)

💰 Annual energy saving: £98.48 📈 5-year energy saving: £492.40 ⏱️ Typical payback period: 3-4 years on energy savings alone

---

📍 Scenario: Right-Sizing from an Oversized 1.0HP Pump

The situation: Your pool installer fitted a 1.0HP pump “to be safe” but your 35,000-litre pool only needs 6-7m³/hr flow.

Factor	❌ Oversized 1.0HP	✅ Correctly-Sized 5P2RC-1
Power consumption	1.18 kW	0.64 kW
Annual energy cost	£447.43	£242.69
Filter wear	Accelerated	Normal
Noise level	Higher	Lower

💰 Annual energy saving: £204.74 📈 5-year energy saving: £1,023.70 💷 10-year saving: Over £2,000

---

📍 Scenario: New Pool Installation

The situation: You’re installing a new 8m × 4m residential pool (approximately 45,000 litres).

Circulation requirement: Pool volume ÷ 6 hours = 7,500 litres/hr = 7.5m³/hr 5P2RC-1 delivery: 7m³/hr at 10m head ✅

Option	Initial Cost	Annual Running Cost	5-Year Total Cost
❌ Budget pump (0.75HP)	Lower	£341.17	Higher
✅ Sta-Rite 5P2RC-1	Moderate	£242.69	Lower
❌ Premium variable speed	Higher	£180-200	Highest initially

💡 Recommendation: The 5P2RC-1 offers the optimal balance of purchase price, running costs, and reliability for standard residential installations.
