💰 Usage Costs & Running Expenses

Understanding the true cost of operating your pool pump helps you make informed decisions and budget effectively. The K-Flo SPK12607XY1’s efficient 820W motor delivers excellent performance while keeping energy costs manageable.

📊 Annual Running Cost Calculation

Power consumption: 0.82 kW (input power P1) UK electricity rate: £0.2635 per kWh (Ofgem Price Cap, Q4 2025)

🏊 Scenario 1: Standard Seasonal Pool (6 months)

• Daily operation: 6 hours (recommended for pools up to 69m³)
• Season length: 180 days (April – September)
• Annual running hours: 6 × 180 = 1,080 hours

✅ Annual electricity cost: 0.82 kW × 1,080 hours × £0.2635 = £233.47

This equates to approximately £1.30 per day during the swimming season.

♨️ Scenario 2: Year-Round Operation (Heated Pool)

• Daily operation: 6 hours
• Operating days: 365 days
• Annual running hours: 6 × 365 = 2,190 hours

✅ Annual electricity cost: 0.82 kW × 2,190 hours × £0.2635 = £473.17

🏊 Scenario 3: Extended Daily Operation

• Daily operation: 8 hours (larger pools or heavy usage)
• Season length: 180 days
• Annual running hours: 8 × 180 = 1,440 hours

✅ Annual electricity cost: 0.82 kW × 1,440 hours × £0.2635 = £311.29

💷 Cost Comparison: K-Flo vs Older Pumps

Many pool owners are still running older, less efficient pumps that consume significantly more power. Here’s how the K-Flo compares:

Pump Type	Power Draw	Annual Cost (1,080 hrs)	Difference
✅ K-Flo 0.75HP	820W	£233.47	–
❌ Older 0.75HP (typical)	950W	£270.53	+£37.06/year
❌ Oversized 1HP pump	1,090W	£310.37	+£76.90/year
❌ Inefficient budget pump	1,100W	£313.22	+£79.75/year

⚡ Motor Efficiency Matters: The K-Flo’s 69.5% motor efficiency (P2/P1 = 570W/820W) means more of your electricity goes towards moving water rather than generating waste heat.

🎯 Real World Examples & Applications

The Hayward K-Flo 0.75HP is engineered to excel across a range of residential and light commercial applications:

🏊‍♂ Residential Swimming Pools

Ideal for family pools up to 69m³ (based on 6-hour turnover). The 11.5m³/hr flow rate ensures complete water circulation, maintaining crystal-clear conditions throughout the swimming season. The quiet operation means you can run the pump during evening hours without disturbing neighbours or family relaxation time.

🌊 Saltwater Pool Systems

The AISI 316 stainless steel mechanical seal and corrosion-proof housing make this pump fully compatible with saltwater chlorination systems. Unlike standard pumps that deteriorate rapidly in salt environments, the K-Flo’s marine-grade components ensure years of trouble-free operation.

🛁 Spa and Hot Tub Circulation

While primarily designed for pool applications, the K-Flo can serve as a circulation pump for larger spa installations. The 35°C maximum water temperature rating accommodates typical spa operating conditions, though dedicated spa pumps may be preferred for high-temperature applications.

🌊 Water Features and Ponds

The reliable flow rate and durable construction make the K-Flo suitable for powering larger water features, ornamental ponds with filtration requirements, and fountain systems. The transparent strainer lid is particularly useful for monitoring debris in natural water applications.

🔄 Direct Replacement for KS Pumps

If you’re upgrading from an older Hayward KS series pump, the K-Flo is specifically designed as a drop-in replacement. The matching footprint and connection sizes mean minimal plumbing modifications, reducing installation time and labour costs.

💡 Cost Savings Examples

Upgrading to a modern, efficient pump like the K-Flo can deliver meaningful savings over time. Here are concrete examples based on real-world scenarios:

📍 Scenario: Replacing an Aging 15-Year-Old Pump

Background: An older 0.75HP pump from 2010 typically draws around 950-1,000W due to motor wear, seal degradation, and outdated design.

Calculation:

• ❌ Old pump power draw: 0.95 kW
• ✅ New K-Flo power draw: 0.82 kW
• ⚡ Power saving: 0.13 kW per running hour
• Running hours per year: 1,080 (6 hours × 180 days)
• Electricity rate: £0.2635/kWh

💰 Annual Savings: 0.13 kW × 1,080 hours × £0.2635 = £37.02 per year

📈 5-Year Savings: £185.10 📈 10-Year Savings: £370.20

📍 Scenario: Downsizing from an Oversized 1HP Pump

Many pools have pumps that are larger than necessary, wasting energy on flow that isn’t needed.

Calculation:

• ❌ Oversized 1HP pump: 1.09 kW (K-Flo 1HP specification)
• ✅ Right-sized K-Flo 0.75HP: 0.82 kW
• ⚡ Power saving: 0.27 kW per running hour
• Running hours per year: 1,080

💰 Annual Savings: 0.27 kW × 1,080 hours × £0.2635 = £76.86 per year

⏱ If pump costs £350, payback period: approximately 4.5 years through energy savings alone

📍 Scenario: Commercial Holiday Let Property

A holiday rental property with a pool runs longer hours to maintain pristine conditions for guests.

Usage: 8 hours daily, 210 days per year (extended season for rentals) Running hours: 1,680 hours annually

Operating Cost	K-Flo 0.75HP	Competitor 0.75HP (900W)
Annual electricity	£362.73	£398.07
Annual saving	£35.34	–
5-year saving	£176.70	–
