💰 Usage Costs & Running Expenses

📊 Annual Running Cost Calculation

The NewMP033M’s 0.25 kW power consumption delivers impressive economy for continuous or seasonal operation:

🏊 Typical Hot Tub Circulation Scenario:

• Power consumption: 0.25 kW
• Daily usage: 6 hours/day (typical circulation cycle)
• Annual operation: 6 hours × 365 days = 2,190 hours/year
• UK commercial electricity rate: £0.26 per kWh (Q4 2024 average)
• ✅ Annual running cost: 0.25 kW × 2,190 hours × £0.26 = £142.35

🌊 Seasonal Pool Operation:

• Power consumption: 0.25 kW
• Swimming season: 8 hours/day × 180 days (May-October)
• Total hours: 1,440 hours/year
• UK commercial electricity rate: £0.26 per kWh
• ✅ Annual running cost: 0.25 kW × 1,440 hours × £0.26 = £93.60

♨️ Year-Round Heated Spa:

• Power consumption: 0.25 kW
• Extended daily operation: 12 hours/day × 365 days
• Total hours: 4,380 hours/year
• UK commercial electricity rate: £0.26 per kWh
• ✅ Annual running cost: 0.25 kW × 4,380 hours × £0.26 = £285.15

💡 Cost Savings Examples

📍 Scenario 1: Upgrading from Older 0.5HP Pump

Many older hot tub installations use oversized 0.5HP pumps that consume significantly more energy than necessary for adequate circulation:

❌ Old 0.5HP pump annual cost:

• Power: 0.37 kW
• Usage: 6 hours/day × 365 days = 2,190 hours
• Cost: 0.37 × 2,190 × £0.26 = £210.68/year

✅ NewMP033M annual cost:

• Power: 0.25 kW
• Usage: Same operation (2,190 hours)
• Cost: 0.25 × 2,190 × £0.26 = £142.35/year

💰 Annual saving: £68.33 ⏱️ 3-year saving: £205 📈 5-year saving: £342

The NewMP033M pays for itself through energy savings whilst providing equivalent circulation performance for small to medium systems.

📍 Scenario 2: Replacing Inefficient Budget Pump

Budget pumps often feature older motor designs with poor efficiency ratings and higher energy consumption:

❌ Typical budget 0.33HP pump:

• Actual power draw: 0.30 kW (poor motor efficiency)
• Usage: 6 hours/day × 365 days = 2,190 hours
• Cost: 0.30 × 2,190 × £0.26 = £170.82/year

✅ Certikin NewMP033M:

• Efficient motor design: 0.25 kW
• Same usage: 2,190 hours
• Cost: 0.25 × 2,190 × £0.26 = £142.35/year

💰 Annual saving: £28.47 ⏱️ Over 5 years: £142 saved

Beyond energy savings, genuine Certikin construction means fewer breakdowns, longer component life, and reduced maintenance costs compared to budget alternatives.

📍 Scenario 3: Commercial Installation (Multiple Units)

For facilities operating multiple hot tubs or small pools, the cumulative savings become substantial:

Operating 3 pumps, 8 hours/day, year-round:

❌ Using 0.37 kW pumps:

• Total power: 3 × 0.37 = 1.11 kW
• Annual hours: 8 × 365 = 2,920 hours
• Cost: 1.11 × 2,920 × £0.26 = £843.89/year

✅ Using NewMP033M pumps:

• Total power: 3 × 0.25 = 0.75 kW
• Same hours: 2,920 hours
• Cost: 0.75 × 2,920 × £0.26 = £569.40/year

💰 Annual facility saving: £274.49 📊 3-year saving: £823 💷 5-year saving: £1,372

For commercial operators, these savings go directly to the bottom line whilst reducing environmental impact and future-proofing against rising energy costs.

🎯 Real World Examples & Applications

🛁 Residential Hot Tubs & Spas

The NewMP033M excels as a primary circulation pump for hot tubs up to 1,200 litres, providing consistent water turnover whilst maintaining whisper-quiet operation. The compact 438mm length fits into tight equipment bays typical of modern spa cabinets, whilst the self-priming capability eliminates installation complications. Homeowners particularly value the transparent pre-filter lid – enabling quick visual checks without tools or disassembly during routine maintenance.

Typical installation: 4-6 person hot tub, 6-8 hours daily circulation, paired with cartridge filtration or sand filter system.

🏊‍♂️ Small Above-Ground Pools

For above-ground pools up to 15,000 litres, the NewMP033M provides adequate circulation for effective chemical distribution and surface skimming. The pump’s self-priming capability up to 2 meters means it can be positioned at ground level even when the pool waterline sits elevated, simplifying winterisation and equipment protection. The salt chlorination compatibility makes it ideal for modern saltwater pool conversions.

Typical installation: 12-15ft diameter pools, seasonal operation (May-October), 6-8 hours daily filtration.

🌊 Decorative Water Features

Landscape designers specify the NewMP033M for pond circulation systems and ornamental fountains where reliable operation and low maintenance are priorities. The stainless steel shaft and salt-compatible construction handle varying water chemistry, whilst the integrated pre-filter protects against leaf debris and organic matter. The compact footprint allows discreet installation in limited plant room spaces.

Typical installation: Decorative ponds 5,000-10,000 litres, koi ponds with mechanical pre-filtration, continuous operation with timer control.

🔄 Hot Tub Circulation System Upgrades

When replacing failed pumps in existing installations, the NewMP033M’s standard Ø50mm connections with included 1½” bushings ensure compatibility with most European and UK plumbing configurations. The equivalent 438mm footprint to previous-generation models means it drops into existing mounting positions without modification, whilst the IP55 motor protection provides peace of mind in humid equipment compartments.

Typical installation: Direct replacement for failed Onga, Waterway, or similar compact circulation pumps in 8-12 year old spa systems.

🏢 Leisure Centre Treatment Rooms

Smaller commercial installations such as hotel spa treatment rooms or physiotherapy hydrotherapy pools benefit from the NewMP033M’s reliable performance and low noise output. The 62 dBA operational volume won’t disturb adjacent treatment spaces, whilst the thermal overload protection prevents nuisance shutdowns during extended daily operation. The 2-year commercial warranty provides facility managers with confidence in long-term reliability.

Typical installation: Single-occupancy hydrotherapy tubs, treatment room spa baths, 8-12 hours daily operation with scheduled maintenance.
