💰 Usage Costs & Running Expenses

📊 Annual Running Cost Calculation

Understanding the true cost of operating your pool pump is essential for budgeting and comparing equipment options. Here’s the realistic breakdown for the NEWMP025M:

Power Consumption: 0.20kW (200 watts)
Current UK Electricity Rate: £0.2635 per kWh (October-December 2025 average)

🏊 Scenario 1: Seasonal Pool Use (Standard Operation)

Usage Pattern: 6 hours/day for 6 months (180 days/year)

• Daily consumption: 0.20kW × 6 hours = 1.2 kWh
• Daily cost: 1.2 kWh × £0.2635 = £0.32
• ✅ Annual running cost: £57.60

This scenario suits typical UK outdoor pool owners who operate their pool from April to September.

♨️ Scenario 2: Hot Tub / Year-Round Circulation (Extended Operation)

Usage Pattern: 8 hours/day, 365 days/year

• Daily consumption: 0.20kW × 8 hours = 1.6 kWh
• Daily cost: 1.6 kWh × £0.2635 = £0.42
• ✅ Annual running cost: £153.96

Suitable for hot tubs, heated pools, or installations requiring year-round filtration.

🔄 Scenario 3: Continuous Circulation (24/7 Operation)

Usage Pattern: 24 hours/day, 365 days/year

• Daily consumption: 0.20kW × 24 hours = 4.8 kWh
• Daily cost: 4.8 kWh × £0.2635 = £1.26
• ✅ Annual running cost: £461.88

Only recommended for systems requiring constant circulation, such as specialised water features or treatment systems.

💡 Cost Savings Examples

📍 Scenario: Upgrading from Older 0.37kW (½ HP) Pump

Many homeowners are surprised to discover their older pump is significantly oversized for their actual needs. Here’s what upgrading to the appropriately-sized NEWMP025M could save you:

Old Pump Consumption: 0.37kW
NEWMP025M Consumption: 0.20kW
Usage: 6 hours/day for 180 days

❌ Old pump annual cost:
0.37kW × 6 hours × 180 days × £0.2635 = £105.48

✅ NEWMP025M annual cost:
0.20kW × 6 hours × 180 days × £0.2635 = £57.60

💰 Annual saving: £47.88
📈 3-year saving: £143.64
⏱️ Payback period: Approximately 2 seasons (assuming £200 upgrade cost)

📍 Scenario: Hot Tub – Replacing Inefficient Older Model

Hot tub pumps often run extended hours, making efficiency differences particularly impactful on running costs.

Old inefficient pump: 0.33kW (common older model)
Usage: 8 hours/day, 365 days/year

❌ Old pump annual cost:
0.33kW × 8 hours × 365 days × £0.2635 = £254.43

✅ NEWMP025M annual cost:
0.20kW × 8 hours × 365 days × £0.2635 = £153.96

💰 Annual saving: £100.47
💵 5-year saving: £502.35
📊 Long-term benefit: Over 5 years, you’ll save enough to purchase a brand new replacement pump

Additional Benefit: The NEWMP025M’s built-in thermal protection and IP55 rating mean longer service life and reduced maintenance costs compared to budget alternatives.

🎯 Real World Examples & Applications

🏊‍♂️ Small Residential Swimming Pools

The NEWMP025M excels in pools up to approximately 20m³ (roughly 4m × 3m × 1.5m deep). Perfect for compact garden pools, plunge pools, or exercise pools where space is limited but water quality cannot be compromised. Provides complete water turnover every 6-8 hours when properly sized to your filtration system.

Typical Installation: Connected to sand filter (400-500mm diameter), skimmer, and return jets. Pump installed in dedicated pump house or outdoor enclosure with adequate ventilation. Many installers position the pump below water level to maximise self-priming reliability.

🛁 Hot Tubs & Spa Systems

Ideal as a dedicated circulation pump for hot tubs and spa installations requiring continuous water movement. The compact footprint fits easily within spa cabinets, and the IP55 protection handles the humid environment without issues. The 0.20kW consumption makes 24/7 operation economically viable.

Typical Performance: In a 1,500-litre hot tub, provides complete water circulation approximately 4-5 times per hour, ensuring effective filtration and even heat distribution throughout the spa.

🌊 Water Features & Ornamental Ponds

The NEWMP025M’s self-priming capability and transparent pre-filter make it excellent for decorative water features, fountains, and koi ponds where debris management is critical. The stainless steel shaft and chemical-resistant construction ensure longevity even with water treatments.

Maintenance Advantage: The clear lid pre-filter allows quick visual checks, essential for applications where leaves and organic debris are common.

🔄 Upgrade Replacement for Oversized Pumps

Many older pool installations used significantly oversized pumps (½HP or ¾HP) when a ¼HP pump would suffice. Upgrading to the NEWMP025M provides adequate circulation while drastically reducing energy consumption. Particularly beneficial for pools with upgraded filtration systems that require less flow than original designs.

☀️ Seasonal Pool Circulation

For UK pool owners who operate seasonally (April-September), the NEWMP025M’s 2-year warranty and robust construction mean reliable spring start-up year after year. The drain plug simplifies winterisation, preventing freeze damage during months of inactivity.
