🎯 Real World Examples & Applications

🏊‍♂️ Medium to Large Residential Pools

The 15m³/hr flow rate is ideally matched to pools between 60,000 and 90,000 litres, providing complete water turnover every 4-6 hours as recommended by pool industry guidelines. Perfect for larger family pools measuring approximately 10m × 5m with depths up to 2m, or kidney-shaped pools with similar volumes.

🌊 Counter-Current & Swim Spa Systems

Where higher flow rates are required for counter-current swimming units or integrated swim spa jets, the 5P2RE-1 delivers the necessary volume and pressure. The high-head capability (up to 22.5m) ensures consistent performance even with additional system resistance from jet nozzles and pipework.

🏢 Small Commercial Applications

Ideal for holiday cottage pools, B&B guest facilities, small hotel pools, and rental property installations where reliability is paramount. The robust construction, thermal protection, and extended warranty provide peace of mind for property managers who cannot afford equipment failures during peak letting seasons.

🛁 Large Hot Tubs & Swim Spas

For commercial-grade swim spas or large hot tub installations requiring dedicated circulation pumps, the 5P2RE-1 offers the flow capacity and continuous-duty rating needed. Salt resistance ensures compatibility with modern saltwater sanitisation systems increasingly popular in the spa industry.

🌊 Water Features & Fountains

The exceptional head capability makes this pump suitable for ambitious water features requiring significant lift – elevated fountains, multi-tier cascades, and decorative waterfalls. The quiet motor operation remains unobtrusive even in garden settings where noise would detract from the ambiance.

🔄 Direct Replacement & Upgrades

As a like-for-like replacement for ageing Sta-Rite 5P2R series pumps or equivalent 1.0HP models from other manufacturers, the 5P2RE-1 offers improved efficiency and comprehensive warranty coverage. Standard 1½” BSP connections ensure straightforward installation with existing pipework.

💡 Cost Savings Examples

📍 Scenario: Upgrading from an Inefficient 15-Year-Old Pump

The situation: Your original 1.0HP pool pump has been running since 2010 and efficiency has degraded significantly.

Factor	❌ Ageing 1.0HP Pump	✅ New 5P2RE-1
Power consumption	~1.45 kW (degraded)	1.18 kW
Annual energy cost	£550.22	£447.78
Reliability	Increasing failures	3-year warranty
Noise level	Increasingly loud	Quiet operation
Seal condition	Likely leaking	New precision seal

💰 Annual energy saving: £102.44 📈 5-year energy saving: £512.20 ⏱️ Typical payback period: 2-3 years on energy savings alone (before accounting for avoided repair costs)

📍 Scenario: Right-Sizing from an Oversized 1.5HP Pump

The situation: Your 70,000-litre pool was fitted with a 1.5HP pump by an overly cautious installer. Your actual circulation need is 12-14m³/hr.

Factor	❌ Oversized 1.5HP	✅ Correctly-Sized 5P2RE-1
Power consumption	1.43 kW	1.18 kW
Annual energy cost	£542.76	£447.78
Flow rate	18 m³/hr (excessive)	15 m³/hr (optimal)
Filter wear	Accelerated	Normal
Noise level	Higher	Lower

💰 Annual energy saving: £94.98 📈 5-year energy saving: £474.90 💷 10-year saving: £949.80

💡 Additional benefit: Correctly-sized pumps reduce wear on filters, heaters, and pipework, extending the life of your entire pool system.

📍 Scenario: New Build 10m × 5m Pool Installation

The situation: You’re installing a new 75,000-litre residential pool and need to select the right pump.

Circulation requirement: Pool volume ÷ 5 hours = 15,000 litres/hr = 15m³/hr 5P2RE-1 delivery: 15m³/hr at 10m head ✅ Perfect match

Option	Flow Rate	Annual Running Cost	Suitability
❌ 0.75HP pump	12 m³/hr	£359.93	Undersized – poor circulation
✅ 5P2RE-1 (1.0HP)	15 m³/hr	£447.78	Optimal choice
❌ 1.5HP pump	18 m³/hr	£542.76	Oversized – wasted energy

💡 Recommendation: The 5P2RE-1 provides the ideal balance of adequate flow, energy efficiency, and purchase cost for pools in the 60,000-90,000 litre range.

📍 Scenario: Holiday Let Property – Maximising ROI

The situation: You own a holiday cottage with a pool and need reliable equipment that minimises both running costs and maintenance call-outs.

Annual letting period: 30 weeks (April–October) Pool pump operation: 8 hours/day × 210 days = 1,680 hours

Cost Factor	❌ Budget Pump	✅ Sta-Rite 5P2RE-1
Purchase price	Lower	Moderate
Annual energy (1,680 hrs)	£598.46	£522.41
Typical lifespan	3-5 years	8-12 years
Warranty	1 year	3 years
Emergency call-out risk	Higher	Lower

💰 Annual energy saving: £76.05 📈 Energy saving over 10-year life: £760.50 ⏱️ Avoided emergency repairs: Potentially £200-400+ per incident

💷 True cost of ownership: When factoring in reliability, longevity, and the cost of emergency repairs during peak letting season, the Sta-Rite 5P2RE-1 delivers superior value despite a higher initial purchase price.
