💰 Usage Costs & Running Expenses
The Sta-Rite HD 1.0 HP delivers impressive flow rates from a remarkably efficient 0.75 kW motor. Here’s what it costs to run in real-world scenarios.
📊 Annual Running Cost Calculation
Base Parameters:
- Power consumption: 0.75 kW
- Current UK electricity rate: £0.2635 per kWh (Ofgem Price Cap, Q4 2025)
🏊 Scenario 1: Seasonal Residential Pool (May–September)
Typical UK outdoor pool operation during the swimming season.
Calculation:
- Daily runtime: 8 hours
- Swimming season: 150 days (May–September)
- Annual operating hours: 8 × 150 = 1,200 hours

- ✅ Annual running cost: 900 × £0.2635 = £237.15
💵 Monthly cost during season: approximately £47
♨️ Scenario 2: Year-Round Heated/Indoor Pool
For pools operating throughout the year with consistent filtration.
Calculation:
- Daily runtime: 10 hours
- Operating days: 365 days
- Annual operating hours: 10 × 365 = 3,650 hours
- Energy consumption: 0.75 kW × 3,650 hours = 2,737.5 kWh
- ✅ Annual running cost: 2,737.5 × £0.2635 = £721.33
💷 Monthly cost: approximately £60
🏢 Scenario 3: Extended Daily Operation
Holiday lets, rental properties, or heavily-used pools requiring longer filtration cycles.
Calculation:
- Daily runtime: 12 hours
- Operating days: 200 days
- Annual operating hours: 12 × 200 = 2,400 hours
- Energy consumption: 0.75 kW × 2,400 hours = 1,800 kWh
- ✅ Annual running cost: 1,800 × £0.2635 = £474.30
💰 Monthly cost during season: approximately £79

🎯 Real World Applications
🏊♂️ Medium Residential Pools (70,000–120,000 Litres)
The Sta-Rite HD 1.0 HP is perfectly sized for typical UK domestic pools. With 21 m³/hr flow, an 80,000-litre pool achieves complete turnover in under 4 hours—ideal for maintaining crystal-clear water quality without excessive energy consumption.
🌊 Saltwater Pool Installations
With certified salt resistance up to 0.40%, the Sta-Rite HD is purpose-built for salt chlorination systems. The PPO resin impeller and stainless steel components resist the corrosive effects that destroy lesser pumps in saltwater environments.
🏠 Holiday Let & Rental Properties
The XL pre-filter basket and tool-free ¼ turn lid make maintenance quick and simple—essential for properties where guests or cleaning staff handle routine pump care. The 3-year warranty provides peace of mind for rental investments.
🔄 5P6R Series Replacement
The Sta-Rite HD is a direct replacement for the popular 5P6R series, featuring the same connection sizes and mounting dimensions. Upgrading delivers improved efficiency, enhanced flow rates, and modern construction without pipework modifications.
🌿 Pools with Heavy Debris
Gardens with overhanging trees or significant leaf fall benefit from the XL basket capacity. Longer intervals between cleaning mean less maintenance disruption and more consistent filtration performance.
☀️ Outdoor Installations
The IP-X5 weather protection rating ensures reliable operation in exposed locations. The stainless steel locking clamp and corrosion-resistant construction handle UK weather conditions year after year.
💡 Cost Savings Examples
📍 Scenario: Upgrading from an Ageing 1.0 HP Pump
Older pumps typically consume 25–35% more electricity than modern designs due to worn components, degraded bearings, and outdated motor technology.
Example comparison:
- ❌ Aged pump power draw: approximately 1.00 kW
- ✅ New Sta-Rite HD 1.0 HP: 0.75 kW
- Usage: 8 hours/day × 150 days = 1,200 hours annually
Annual energy consumption:
- ❌ Old pump: 1.00 kW × 1,200 = 1,200 kWh = £316.20
- ✅ Sta-Rite HD: 0.75 kW × 1,200 = 900 kWh = £237.15
💰 Annual saving: £79.05
📈 5-year savings: £395.25
⏱️ Payback on efficiency gains: approximately 8 years (energy savings alone)
Note: When replacing a failing pump, the full purchase price is justified by avoiding pool downtime and water quality issues—energy savings are an additional bonus.
📍 Scenario: Choosing Quality Over Budget Equipment
Budget pumps often have poor hydraulic efficiency, inferior bearings, and shorter lifespans. The total cost of ownership tells the real story.
5-year comparison (8 hours/day, 150 days/year = 1,200 hours annually):
| Factor | Budget 1.0 HP | Sta-Rite HD 1.0 HP |
|---|---|---|
| Purchase price | £400 | £629.00 |
| Power consumption | 0.90 kW | 0.75 kW |
| Annual energy cost | £284.58 | £237.15 |
| 5-year energy cost | £1,422.90 | £1,185.75 |
| Expected lifespan | 3–5 years | 8–12 years |
| Warranty | 1 year | 3 years |
| 5-year total cost | £1,822.90 | £1,814.75 |
💷 The Sta-Rite HD costs LESS over 5 years—with double the expected lifespan remaining
📍 Scenario: Right-Sizing from an Oversized Pump
Many pools have oversized pumps installed by builders who specified “bigger is better.” Downsizing to the correct capacity saves energy without sacrificing water quality.
Example comparison:
- ❌ Oversized 1.5 HP pump: 1.10 kW
- ✅ Right-sized Sta-Rite HD 1.0 HP: 0.75 kW
- Year-round operation: 10 hours/day × 365 days = 3,650 hours
Annual energy consumption:
- ❌ 1.5 HP pump: 1.10 kW × 3,650 = 4,015 kWh = £1,057.95
- ✅ Sta-Rite HD: 0.75 kW × 3,650 = 2,737.5 kWh = £721.33
💰 Annual saving: £336.62
📈 3-year savings: £1,009.86
⏱️ Payback period: under 2 years
