💰 Usage Costs & Running Expenses

📊 Annual Running Cost Calculation

Residential Pool – 6 Month Season:

• Power consumption: 0.37kW
• Daily operation: 8 hours/day
• Operating season: 180 days/year (April-September)
• Annual usage: 8 × 180 = 1,440 hours
• UK average electricity rate: £0.26 per kWh (residential, 2024)
• ✅ Annual running cost: 0.37 × 1,440 × £0.26 = £138.67

Hot Tub – Year-Round Operation:

• Power consumption: 0.37kW
• Daily operation: 6 hours/day
• Operating season: 365 days/year
• Annual usage: 6 × 365 = 2,190 hours
• UK average electricity rate: £0.26 per kWh
• ✅ Annual running cost: 0.37 × 2,190 × £0.26 = £210.64

💡 Cost Comparison vs. Older Technology

Upgrading from an older 0.75HP pump:

❌ Old 0.75HP pump (0.55kW):

• Annual cost (6-month pool): 0.55 × 1,440 × £0.26 = £206.06

✅ New NEWMP050M (0.37kW):

• Annual cost (6-month pool): £138.67
• 💰 Annual saving: £67.39
• ⏱ 3-year saving: £202.17

Why it matters: The 0.50HP pump provides sufficient circulation for small pools while using 33% less energy than typical 0.75HP alternatives. Over a 5-year lifespan, you’ll save approximately £337 in electricity costs alone.

📈 Energy Efficiency Benefits

⚡ Lower Current Draw: At just 3.6A, the NEWMP050M reduces electrical load compared to higher-power alternatives, potentially avoiding the need for circuit upgrades in older properties

💵 Protection Against Price Increases: With UK electricity prices remaining volatile (currently 75% higher than 2021 levels), the lower power consumption provides built-in protection against future rate increases

🌍 Reduced Carbon Footprint: Operating at 0.37kW vs 0.55kW saves approximately 259 kWh annually, equivalent to reducing CO₂ emissions by approximately 54kg per year (based on UK grid average)

🎯 Real World Examples & Applications

🏊‍♂️ Small Residential Swimming Pools

Ideal for domestic pools up to 30,000 litres (approximately 4m × 8m × 1.2m average depth). The 0.50HP rating provides adequate turnover for typical residential installations, circulating the entire pool volume through the filtration system in 6-8 hours. Self-priming capability means the pump can be installed in plant rooms up to 2m above water level, offering installation flexibility in properties with basement or ground-level equipment rooms.

🛁 Hot Tubs & Swim Spas

Perfect circulation pump for hot tubs and compact swim spas. The stainless steel shaft and salt-compatible construction make it particularly suited to salt chlorination systems, increasingly popular in hot tub applications. The compact 438mm length fits easily into crowded equipment bays typical of hot tub installations. Built-in thermal protection is essential in hot tub applications where higher water temperatures (up to 40°C) increase motor operating temperatures.

🌊 Water Features & Ornamental Ponds

Excellent for recirculating water features, koi ponds, and ornamental fountain systems requiring reliable, continuous operation. The pre-filter protects against leaves and debris, while the self-priming design simplifies seasonal start-up. The IP55 motor protection ensures reliable outdoor performance in exposed locations.

🔄 Replacement & Upgrade Applications

Common replacement for aging pumps in existing installations, particularly where original equipment has failed or energy consumption needs to be reduced. The universal 50mm/1½” connection adaptors ensure compatibility with most existing plumbing. Horizontal mounting footprint matches many legacy pumps, simplifying retrofit installations without pipework modifications.

☀️ Seasonal Pool Operations

Designed for seasonal pool use typical in the UK climate. The drain plug allows complete water evacuation for winter storage, protecting against frost damage. The pre-filter basket can be easily removed for thorough cleaning before winter shutdown, ensuring trouble-free spring restart.
