💰 Usage Costs & Running Expenses

The InverEco DE19 VS delivers exceptional value through dramatically reduced electricity consumption. Understanding the real-world running costs demonstrates why variable speed technology represents such a compelling investment.

📊 Annual Running Cost Calculation

Base Parameters:

• Maximum power consumption: 0.80 kW
• UK electricity rate: £0.2635 per kWh (Q4 2025 Ofgem price cap)

Variable Speed Reality: At typical filtration speeds (50–70%), actual power consumption drops significantly below maximum rating, delivering substantial savings versus fixed-speed alternatives.

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

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

Parameter	Calculation
Power at 50% Speed	~0.42 kW (typical)
Daily Runtime	8 hours
Season Length	180 days (April–September)
Annual Hours	1,440 hours
Energy Consumption	0.42 kW × 1,440 hours = 605 kWh
✅ Annual Cost	605 kWh × £0.2635 = £159.42

🏊 Scenario 2: Larger Pool – Extended Daily Filtration

Usage Pattern: 10 hours daily at 60% speed for 180 days (seasonal)

Parameter	Calculation
Power at 60% Speed	~0.50 kW (typical)
Daily Runtime	10 hours
Season Length	180 days
Annual Hours	1,800 hours
Energy Consumption	0.50 kW × 1,800 hours = 900 kWh
✅ Annual Cost	900 kWh × £0.2635 = £237.15

🏢 Scenario 3: Year-Round Indoor Pool or Swim Spa

Usage Pattern: 12 hours daily at 60% speed for 365 days

Parameter	Calculation
Power at 60% Speed	~0.50 kW (typical)
Daily Runtime	12 hours
Annual Hours	4,380 hours
Energy Consumption	0.50 kW × 4,380 hours = 2,190 kWh
✅ Annual Cost	2,190 kWh × £0.2635 = £577.07

♨️ Scenario 4: Swim Spa – Continuous Low-Speed Circulation

Usage Pattern: 24/7 circulation at 30% speed

Parameter	Calculation
Power at 30% Speed	~0.28 kW (typical)
Daily Runtime	24 hours
Annual Hours	8,760 hours
Energy Consumption	0.28 kW × 8,760 hours = 2,453 kWh
✅ Annual Cost	2,453 kWh × £0.2635 = £646.37

⚡ Comparison: Variable Speed vs Single-Speed Pumps

Traditional single-speed pumps in the 0.75–1.5 kW range must operate at full power constantly, consuming far more electricity for equivalent filtration results.

Pump Type	Power	Annual Hours (Seasonal 8hr)	Annual kWh	Annual Cost	vs DE19 VS
❌ Single-Speed 0.75 kW	0.75 kW	1,440	1,080 kWh	£284.58	—
❌ Single-Speed 1.1 kW	1.10 kW	1,440	1,584 kWh	£417.38	—
❌ Single-Speed 1.5 kW	1.50 kW	1,440	2,160 kWh	£569.16	—
✅ InverEco DE19 VS @ 50%	0.42 kW	1,440	605 kWh	£159.42	—

💰 Annual Savings vs 0.75 kW Single-Speed: £125.16

💰 Annual Savings vs 1.1 kW Single-Speed: £257.96

💷 Annual Savings vs 1.5 kW Single-Speed: £409.74

📈 5-Year Savings vs 1.5 kW Single-Speed: £2,048.70

🎯 Real World Examples & Applications

🏊 Medium to Large Residential Pools (30–50 m³)

The DE19 VS excels in family-sized pools where reliable circulation is essential. A typical 40 m³ pool achieves complete water turnover in approximately 2–2.5 hours at 60% speed, enabling thorough overnight filtration while minimising electricity consumption. The powerful 23.5 m³/h maximum flow handles demanding cleaning sessions and rapid backwashing when needed.

🌊 Swim Spas & Exercise Pools

Swim spas require consistent, powerful circulation for both filtration and jet operation. The DE19 VS provides excellent low-speed efficiency for continuous filtration while delivering sufficient flow for swim current systems. The quiet 36 dB operation is essential for relaxation-focused installations where motor noise would be intrusive.

🏢 Small Commercial Installations

Holiday let pools, B&B facilities, and small wellness centres benefit from the DE19 VS’s combination of commercial-grade reliability and residential-level running costs. The extended warranty, robust construction, and programmable timers suit applications requiring dependable automated operation.

🔄 Upgrade from Older 1.0–1.5 kW Pumps

Pool owners with ageing single-speed pumps in the 1.0–1.5 kW range find the DE19 VS delivers equivalent or superior water circulation at dramatically lower running costs. The 17m maximum head capability handles installations where older pumps struggle with pipe friction and elevation changes.

🏠 Pools with Challenging Pipework

Installations featuring long pipe runs, multiple water features, or equipment located above pool level benefit from the DE19 VS’s strong pressure capability. The 17m maximum head ensures reliable flow even in demanding configurations where lesser pumps would underperform.

🛁 Large Plunge Pools & Cold Water Therapy

The growing popularity of cold water immersion pools creates demand for quiet, efficient circulation. The DE19 VS maintains water quality through gentle continuous circulation while operating virtually silently—essential for therapeutic environments.

💡 Cost Savings Examples

📍 Scenario: Upgrading from a 1.1 kW Single-Speed Pump

A pool owner running an older 1.1 kW pump for 8 hours daily during a 6-month season currently spends approximately £417 annually on pump electricity alone.

Current Setup	InverEco DE19 VS
❌ Power: 1.1 kW constant	✅ Power: 0.42 kW (50% speed)
❌ Annual consumption: 1,584 kWh	✅ Annual consumption: 605 kWh
❌ Annual cost: £417.38	✅ Annual cost: £159.42

💰 Annual Saving: £257.96

⏱️ Payback Period: Pump investment typically recovered in 2–3 years through electricity savings.

📈 10-Year Saving: £2,579.60

---

📍 Scenario: Running Longer for Better Water Quality

Variable speed technology enables extended filtration without increased costs. Many pool professionals recommend longer run times at lower speeds for superior water clarity.

Traditional Single-Speed Approach:

• ❌ 8 hours at 1.1 kW = 8.8 kWh daily = £2.32/day

InverEco DE19 VS Approach:

• ✅ 12 hours at 50% speed (0.42 kW) = 5.04 kWh daily = £1.33/day

💵 Result: 43% lower daily cost despite 50% longer filtration, plus noticeably improved water quality.

📍 Scenario: Year-Round Commercial Operation

Small commercial pools operating year-round generate substantial savings:

Operation Pattern	Single-Speed (1.5 kW)	InverEco DE19 VS (0.50 kW @ 60%)
Daily Hours	12 hours	12 hours
Annual Hours	4,380 hours	4,380 hours
Annual kWh	6,570 kWh	2,190 kWh
❌ Annual Cost	£1,731.20	—
✅ Annual Cost	—	£577.07

💷 Annual Saving: £1,154.13

📈 5-Year Saving: £5,770.65

⏱️ Payback Period: Less than 1 year for most commercial installations.

📍 Scenario: Comparison with Smaller DE15 Model

For pools at the upper end of the DE15’s range (35–45 m³), upgrading to the DE19 provides additional capacity headroom with minimal cost increase:

Model	Power @ 60%	Flow @ 8m Head	Annual Cost (10hr/day, seasonal)
InverEco DE15 VS	~0.42 kW	15 m³/h	£199.28
InverEco DE19 VS	~0.50 kW	19 m³/h	£237.15

💵 Extra Capacity Premium: Only £37.87/year for 27% more flow capacity—excellent value for borderline pool sizes.
