💰 Usage Costs & Running Expenses

📊 Annual Running Cost Calculation

Understanding your pump’s operating costs helps you budget effectively and identify savings opportunities. Here’s a realistic cost breakdown for the HGS051SM:

⚡ Power Consumption: 0.37 kW

📅 Typical Usage Scenario – 6-Month Pool Season:

• Daily runtime: 6 hours (standard filtration requirement)
• Operating days: 180 days (May through October)
• Total annual hours: 6 × 180 = 1,080 hours/year

💷 Current UK Electricity Rate: £0.26 per kWh (Ofgem price cap, Q4 2025)

✅ Annual Running Cost:

• 0.37 kW × 1,080 hours × £0.26/kWh = £104.33 per year

🏊 Cost Analysis by Usage Pattern

Usage Scenario	Hours/Day	Days/Year	Annual kWh	Annual Cost
Light Use (Small pool, short season)	4 hours	150 days	222 kWh	£57.72
Standard Use (Medium pool, full season)	6 hours	180 days	400 kWh	£104.33
Heavy Use (Large pool/hot tub, extended season)	8 hours	240 days	710 kWh	£184.60
Year-Round (Heated pool/spa)	6 hours	365 days	812 kWh	£211.12

💡 Energy Efficiency Comparison

Upgrading from an Older 0.75HP Pump:

Many homeowners are still running older, less efficient 0.75HP (0.55kW) pumps when a modern 0.5HP unit provides adequate circulation for their pool size.

❌ Old 0.75HP Pump Annual Cost:

• Power: 0.55 kW
• Usage: 6 hours/day × 180 days = 1,080 hours
• Cost: 0.55 × 1,080 × £0.26 = £154.44/year

✅ Swimflo Plus HGS051SM Annual Cost:

• £104.33/year

💵 Annual Saving: £50.11 📈 3-Year Saving: £150.33

⏱ Payback Period: Depending on pump cost, energy savings alone can offset a significant portion of the investment over the pump’s operational lifetime (typically 10+ years), meaning total lifecycle savings of £500+.

⚡ Energy Efficiency Advantage: The HGS051SM’s high hydraulic efficiency means it moves more water per watt consumed compared to older pump designs. This modern pump technology typically offers 15-20% better efficiency than pumps manufactured before 2015.

🎯 Real World Examples & Applications

🏊‍♂️ Residential Swimming Pools

Ideal for domestic pools up to 40,000 litres (approximately 4m × 8m). The HGS051SM provides complete water circulation through sand filters, cartridge filters, or DE filters, maintaining crystal-clear water throughout the swimming season. Perfect for families wanting reliable, efficient pool filtration without oversized equipment.

🛁 Hot Tubs & Spa Pools

Excellent choice as the primary circulation pump for medium-sized hot tubs and spa pools. The compact design fits neatly into spa cabinets while the salt-compatible construction supports modern ozone and salt sanitization systems popular in spa installations.

🌊 Small Water Features

Powers decorative water features, ornamental ponds, and water gardens where continuous circulation is required. The self-priming capability handles installations where the pump is positioned above water level, eliminating the need for complex plumbing arrangements.

🔄 Replacement & Upgrades

Direct replacement for aging pumps in existing installations. The standard 1.5″ (50mm) connections and compact footprint mean it fits most equipment pads without modification. Many homeowners replace failing single-speed pumps with the HGS051SM to gain modern efficiency and reliability.

🏠 New Pool Installations

Specified by pool builders for small to medium residential pools where a professional-grade pump is required but space is at a premium. The 2-year warranty provides assurance for new construction projects.

☀ Seasonal Pool Operations

Perfect for UK outdoor pools operated seasonally from May to October. The efficient design reduces electricity consumption during peak summer months when filtration demands are highest due to increased bather load and higher temperatures.

💡 Cost Savings Examples

📍 Scenario 1: Replacing a 15-Year-Old Pump

Situation: Homeowner with a 30,000-litre pool running a failing 0.75HP pump from 2010

❌ Old Pump (0.55kW) Annual Cost:

• 6 hours/day × 180 days = 1,080 hours
• 0.55 kW × 1,080 hours × £0.26 = £154.44

✅ Swimflo Plus HGS051SM (0.37kW) Annual Cost:

• 6 hours/day × 180 days = 1,080 hours
• 0.37 kW × 1,080 hours × £0.26 = £104.33

💰 Annual Saving: £50.11 💵 5-Year Saving: £250.55 💷 10-Year Saving: £501.10

⏱ Additional Benefits: New warranty coverage, improved reliability, reduced maintenance, modern salt-compatibility

---

📍 Scenario 2: Right-Sizing from Oversized Equipment

Situation: Pool owner with 35,000-litre pool running an unnecessarily large 1.5HP pump

❌ Oversized 1.5HP Pump (1.1kW) Annual Cost:

• 6 hours/day × 180 days = 1,080 hours
• 1.1 kW × 1,080 hours × £0.26 = £309.96

✅ Correctly-Sized HGS051SM (0.37kW) Annual Cost:

• £104.33

💰 Annual Saving: £205.63 💵 5-Year Saving: £1,028.15

📊 Key Insight: Many pools are over-pumped. The HGS051SM provides adequate circulation for most residential pools while dramatically reducing energy waste. Professional assessment ensures proper sizing for your specific pool volume and filtration requirements.

---

📍 Scenario 3: Protection Against Rising Energy Costs

Future-Proofing Your Operating Costs:

UK electricity prices have increased significantly since 2021. While the current rate is £0.26/kWh, prudent planning accounts for potential future increases.

📈 If electricity rises to £0.35/kWh (realistic 5-year projection):

HGS051SM Annual Cost:

• 400 kWh × £0.35 = £140/year

Compared to 0.75HP alternative:

• 594 kWh × £0.35 = £208/year

💰 Annual saving increases to £68

Energy-efficient equipment provides insurance against future price volatility. Every kWh saved becomes more valuable as energy costs rise.
