💰 Usage Costs & Running Expenses

Understanding your running costs helps you budget effectively and appreciate the efficiency of the AG Pump range.

📊 Annual Running Cost Calculation

Power consumption: 0.49 kW (input power) UK electricity rate: £0.2635 per kWh (Ofgem Price Cap, Q4 2025)

🏊 Scenario 1: Seasonal Above-Ground Pool

Usage pattern: 6 hours per day × 150 days (May to September) Annual operating hours: 900 hours

Calculation:

• Energy consumption: 0.49 kW × 900 hours = 441 kWh per year
• ✅ Annual running cost: 441 × £0.2635 = £116.21

💰 That’s just £0.78 per day during the swimming season!

🌊 Scenario 2: Year-Round Ornamental Pond

Usage pattern: 8 hours per day × 365 days Annual operating hours: 2,920 hours

Calculation:

• Energy consumption: 0.49 kW × 2,920 hours = 1,431 kWh per year
• ✅ Annual running cost: 1,431 × £0.2635 = £377.07

💷 Monthly cost: Approximately £31.42 for continuous water feature operation

🛁 Scenario 3: Spa/Hot Tub Circulation

Usage pattern: 4 hours per day × 300 days Annual operating hours: 1,200 hours

Calculation:

• Energy consumption: 0.49 kW × 1,200 hours = 588 kWh per year
• ✅ Annual running cost: 588 × £0.2635 = £154.94

💵 Less than £13 per month for daily spa enjoyment

⚡ Energy Efficiency Comparison

The AG14-2DC’s efficient 0.49kW input power delivers significant savings compared to older or less efficient pumps:

Pump Type	Input Power	Annual Cost (900hrs)	Difference
✅ Plastica AG 0.5HP	0.49 kW	£116.21	—
❌ Older 0.5HP pump	0.65 kW	£154.15	+£37.94/year
❌ Oversized 0.75HP pump	0.75 kW	£177.86	+£61.65/year

📈 Choosing the right-sized, efficient pump saves you money every season!

🎯 Real World Examples & Applications

🏊‍♂️ Medium-Sized Above-Ground Pools

The AG14-2DC is the ideal circulation pump for above-ground pools up to 40,000 litres. With a maximum flow rate of 241 LPM, it delivers complete water turnover every 2-3 hours – perfect for maintaining water clarity and proper chemical distribution throughout the swimming season.

Typical installation: Positioned in a weatherproof housing near the pool with easy access for basket cleaning. The 1.8m self-priming capability allows placement above water level without priming issues.

---

🛁 Spas & Hot Tubs

For spa owners requiring reliable circulation without the expense of running a larger pump, the AG Pump provides quiet, efficient water movement. The 55dB noise rating ensures relaxation isn’t disturbed, while the chemical-resistant construction handles sanitiser concentrations found in hot tub environments.

Performance note: Ideal for circulation duties rather than jet operation. Many spa installations pair this pump with a separate jet pump for the best of both worlds.

---

🌊 Ornamental Ponds & Water Features

Decorative ponds and water features benefit from the pump’s ability to handle various water conditions. The generous 1.65L strainer basket captures leaves and debris before they reach the impeller, while the transparent lid makes inspection quick and simple.

Application tip: The 12-metre maximum head allows for elevated water features and fountain installations while maintaining adequate flow.

🔄 Upgrade from Ageing Single-Phase Pumps

Replacing an older, inefficient pump with the AG14-2DC delivers immediate benefits: lower running costs, quieter operation, and modern safety features including RCD compatibility. The standard 50mm/1.5″ connections fit most existing pipework systems.

Installation advantage: Single-phase 230V operation means no electrical upgrades are required when replacing like-for-like.

🏠 Residential Indoor Pools

For smaller indoor swimming pools in domestic settings, this pump provides sufficient circulation in a compact package. The IP55 rating protects against the humid conditions found in indoor pool halls, while the low noise output maintains a peaceful environment.

Maintenance consideration: The ambient temperature limit of 40°C means adequate ventilation in the plant room is essential – a requirement the instruction manual emphasises.

💡 Cost Savings Examples

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

Situation: A homeowner’s existing pump draws 0.70kW but only delivers similar performance to the AG 0.5HP.

Current annual cost (900 hours):

• ❌ Old pump: 0.70 kW × 900 hrs × £0.2635 = £166.01

New AG Pump annual cost:

• ✅ AG14-2DC: 0.49 kW × 900 hrs × £0.2635 = £116.21

Annual saving: 💰 £49.80 per year

5-year saving: 📈 £249.00

⏱ Payback period: The energy savings alone contribute significantly toward the pump investment, with additional value from improved reliability and reduced maintenance.

📍 Scenario: Right-Sizing from an Oversized Pump

Situation: A pond owner has been running a 0.75HP pump when a 0.5HP would suffice for their 30,000L pond.

Current annual cost (2,920 hours year-round):

• ❌ Oversized 0.75HP: 0.75 kW × 2,920 hrs × £0.2635 = £577.27

Correctly-sized AG Pump:

• ✅ AG14-2DC: 0.49 kW × 2,920 hrs × £0.2635 = £377.07

Annual saving: 💷 £200.20 per year

3-year saving: 📊 £600.60

⏱ Payback period: Significant savings accumulate rapidly for year-round operations, often paying for the new pump within 18-24 months.

📍 Scenario: Commercial Holiday Let Pool

Situation: A holiday cottage owner needs a reliable pump for their above-ground pool that operates intensively during peak season.

Usage: 10 hours/day × 120 days = 1,200 hours

Running cost:

• ✅ AG14-2DC: 0.49 kW × 1,200 hrs × £0.2635 = £154.94 per season

💵 At under £155 per season, the pump costs less than £1.30 per day during operation – an easy cost to factor into holiday rental pricing.
