💧 InverEco DE15 VS 0.66kW Variable Speed Pool Pump

Experience whisper-quiet, ultra-efficient pool circulation with up to 90% energy savings and intelligent speed control.

📋 Product Overview

The InverEco DE15 VS 0.66kW Variable Speed Pool Pump represents the next generation of residential pool circulation technology. Engineered with Aquagem’s advanced InverSilence® inverter technology, this single-phase pump delivers exceptional performance while consuming a fraction of the energy used by traditional single-speed alternatives.

Designed specifically for residential pools between 20,000 and 40,000 litres (20–40 m³), the DE15 VS combines variable speed control ranging from 30% to 100%, allowing precise adjustment for filtration, cleaning, and backwashing operations. The IE4-rated motor achieves the highest efficiency classification available, translating directly into dramatically lower electricity bills.

💰 Usage Costs & Running Expenses

Understanding running costs is essential when selecting a pool pump. The InverEco DE15 VS delivers exceptional efficiency, dramatically reducing annual electricity expenses.

📊 Annual Running Cost Calculation

Base Parameters:

• Power consumption: 0.66 kW (maximum)
• UK electricity rate: £0.2635 per kWh (Q4 2025 Ofgem price cap)

Variable Speed Advantage: One of the greatest benefits of variable speed technology is that you rarely run at full power. Most filtration occurs at 50–70% speed, consuming significantly less electricity.

🏊 Scenario 1: Residential Pool – Seasonal Use (6 Months)

Usage Pattern: 8 hours daily filtration at 50% speed for 180 days

Parameter	Calculation
Power at 50% Speed	~0.35 kW (typical)
Daily Runtime	8 hours
Season Length	180 days (April–September)
Annual Hours	1,440 hours
Energy Consumption	0.35 kW × 1,440 hours = 504 kWh
✅ Annual Cost	504 kWh × £0.2635 = £132.80

🏊 Scenario 2: Year-Round Indoor Pool

Usage Pattern: 10 hours daily filtration at 60% speed for 365 days

Parameter	Calculation
Power at 60% Speed	~0.42 kW (typical)
Daily Runtime	10 hours
Annual Hours	3,650 hours
Energy Consumption	0.42 kW × 3,650 hours = 1,533 kWh
✅ Annual Cost	1,533 kWh × £0.2635 = £403.95

♨️ Scenario 3: Hot Tub/Spa Application – Continuous Circulation

Usage Pattern: 24/7 low-speed circulation at 30% speed

Parameter	Calculation
Power at 30% Speed	~0.22 kW (typical)
Daily Runtime	24 hours
Annual Hours	8,760 hours
Energy Consumption	0.22 kW × 8,760 hours = 1,927 kWh
✅ Annual Cost	1,927 kWh × £0.2635 = £507.77

⚡ Comparison: Variable Speed vs Single-Speed Pumps

Traditional single-speed pumps of similar capacity typically consume 0.75–1.1 kW and must run at full power constantly.

Pump Type	Power	Annual Hours (Seasonal)	Annual kWh	Annual Cost	Difference
❌ Single-Speed (0.75 kW)	0.75 kW	1,440	1,080 kWh	£284.58	—
❌ Single-Speed (1.0 kW)	1.0 kW	1,440	1,440 kWh	£379.44	—
✅ InverEco DE15 VS @ 50%	0.35 kW	1,440	504 kWh	£132.80	—

💰 Annual Savings vs 0.75 kW Single-Speed: £151.78

💰 Annual Savings vs 1.0 kW Single-Speed: £246.64

💷 5-Year Savings vs 1.0 kW Single-Speed: £1,233.20

🎯 Real World Examples & Applications

🏊 Residential Swimming Pools (20–40 m³)

The DE15 VS is perfectly sized for medium residential pools. Run at 50% speed for daily filtration during swimming season, ramping up to 70–100% only when vacuuming, adding chemicals, or backwashing. A typical 30 m³ garden pool achieves complete water turnover in approximately 2–3 hours at 50% speed, allowing for efficient overnight filtration cycles.

🏠 Above-Ground Pool Upgrades

Replacing noisy, inefficient above-ground pool pumps with the DE15 VS transforms the poolside experience. The dramatic noise reduction—from typical 65–75 dB pumps down to 36 dB—makes evening swims genuinely peaceful. The energy savings often pay for the upgrade within 2–3 seasons.

🌊 Water Features & Koi Ponds

The gentle variable speed control makes this pump excellent for water features where precise flow rates matter. Ornamental ponds benefit from the soft-start technology, which prevents sudden surges that can disturb fish or disrupt delicate plantings. The saltwater compatibility also suits brackish pond applications.

🛁 Swim Spas & Plunge Pools

Smaller warm-water applications benefit enormously from variable speed efficiency. Continuous low-speed circulation maintains water quality while minimising heat loss from excessive water movement. The ultra-quiet operation is essential for relaxation-focused installations.

🔄 Pump Replacement & Retrofits

Upgrading from older single-speed pumps is straightforward thanks to standard 2″ union connections. The compact dimensions (585 × 255 × 325 mm packing size) fit most existing pump houses, and the single-phase 220–240 V supply matches typical UK residential installations without electrical modifications.

💡 Cost Savings Examples

📍 Scenario: Replacing an Ageing 1.0 kW Single-Speed Pump

A pool owner currently running an older 1.0 kW single-speed pump for 8 hours daily during a 6-month season spends approximately £379 annually on pump electricity.

Current Setup	InverEco DE15 VS
❌ Power: 1.0 kW constant	✅ Power: 0.35 kW (50% speed)
❌ Annual consumption: 1,440 kWh	✅ Annual consumption: 504 kWh
❌ Annual cost: £379.44	✅ Annual cost: £132.80

💰 Annual Saving: £246.64

⏱️ Payback Period: Typical pump cost recovered in approximately 2–3 years through energy savings alone.

📈 10-Year Saving: £2,466.40 in reduced electricity costs.

📍 Scenario: Extending Daily Run Time for Better Filtration

Many pool owners discover that running their pump longer at lower speeds improves water clarity. With variable speed technology, you can double your filtration time while still saving money.

Traditional Approach:

• ❌ 6 hours at 1.0 kW = 6 kWh daily

InverEco DE15 VS Approach:

• ✅ 12 hours at 50% speed (0.35 kW) = 4.2 kWh daily

💵 Result: 30% less electricity despite twice the filtration time, plus noticeably clearer water.

📍 Scenario: Year-Round Operation vs Seasonal Shutdown

For covered or indoor pools running year-round, annual savings become substantial:

Operation Pattern	Single-Speed (1.0 kW)	InverEco DE15 VS (0.42 kW @ 60%)
Daily Hours	10 hours	10 hours
Annual Hours	3,650 hours	3,650 hours
Annual kWh	3,650 kWh	1,533 kWh
❌ Annual Cost	£961.78	—
✅ Annual Cost	—	£403.95

💷 Annual Saving: £557.83

📈 5-Year Saving: £2,789.15
