⚡ Comparison: Variable Speed vs Single-Speed Pumps

Traditional single-speed pumps delivering equivalent flow rates typically consume 1.5–2.2 kW and must run at full power constantly, resulting in dramatically higher electricity costs.

Pump Type	Power	Annual Hours (Seasonal 8hr)	Annual kWh	Annual Cost	vs DE23 VS
❌ Single-Speed 1.5 kW	1.50 kW	1,440	2,160 kWh	£569.16	—
❌ Single-Speed 1.8 kW	1.80 kW	1,440	2,592 kWh	£682.99	—
❌ Single-Speed 2.2 kW	2.20 kW	1,440	3,168 kWh	£834.77	—
✅ InverEco DE23 VS @ 50%	0.55 kW	1,440	792 kWh	£208.69	—

💰 Annual Savings vs 1.5 kW Single-Speed: £360.47

💰 Annual Savings vs 1.8 kW Single-Speed: £474.30

💷 Annual Savings vs 2.2 kW Single-Speed: £626.08

📈 5-Year Savings vs 2.2 kW Single-Speed: £3,130.40

🎯 Real World Examples & Applications

🏊 Large Residential Pools (40–70 m³)

The DE23 VS is purpose-built for substantial family pools where lesser pumps struggle to achieve adequate turnover. A 60 m³ pool achieves complete water circulation in approximately 2.5–3 hours at 60% speed, enabling thorough overnight filtration while the 27 m³/h maximum flow handles demanding cleaning sessions and rapid filter backwashing.

🌊 Performance Swim Spas & Endless Pools

Serious swim spa installations requiring powerful jet systems alongside efficient filtration benefit enormously from the DE23 VS’s capacity. The ability to run gentle 30% circulation during rest periods, then ramp to full power for swimming sessions, optimises both energy consumption and performance.

🏢 Light Commercial Applications

Holiday rental properties, boutique hotels, wellness facilities, and small leisure centres find the DE23 VS delivers commercial-grade reliability at residential running costs. The programmable timers and extended warranty suit installations requiring dependable automated operation across multiple daily cycles.

🔄 Upgrading from 1.5–2.2 kW Single-Speed Pumps

Pool owners with ageing high-powered single-speed pumps experience transformative savings with the DE23 VS. Equivalent or superior circulation at a fraction of the electricity cost typically delivers payback within 12–24 months, followed by years of ongoing savings.

🏠 Pools with Multiple Water Features

Installations incorporating waterfalls, fountains, spa jets, or deck-level features requiring substantial combined flow benefit from the DE23 VS’s powerful output. The 19m maximum head handles complex plumbing configurations where multiple features create significant pipe resistance.

♨️ Heated Pools – Accelerating Warmth Distribution

Larger heated pools benefit from the DE23 VS’s ability to increase circulation temporarily during heating cycles, distributing warmth efficiently throughout the water body, then returning to economical low-speed filtration once target temperature is achieved.

💡 Cost Savings Examples

📍 Scenario: Replacing an Ageing 1.8 kW Single-Speed Pump

A pool owner running an older 1.8 kW pump for 8 hours daily during a 6-month season currently spends approximately £683 annually on pump electricity.

Current Setup	InverEco DE23 VS
❌ Power: 1.8 kW constant	✅ Power: 0.55 kW (50% speed)
❌ Annual consumption: 2,592 kWh	✅ Annual consumption: 792 kWh
❌ Annual cost: £682.99	✅ Annual cost: £208.69

💰 Annual Saving: £474.30

⏱️ Payback Period: Pump investment typically recovered in under 2 years through electricity savings alone.

📈 10-Year Saving: £4,743.00

📍 Scenario: Commercial Pool – Year-Round Operation

A small hotel or leisure facility operating year-round with an older 2.2 kW pump running 12 hours daily faces substantial electricity costs:

Operation Pattern	Single-Speed (2.2 kW)	InverEco DE23 VS (0.68 kW @ 60%)
Daily Hours	12 hours	12 hours
Annual Hours	4,380 hours	4,380 hours
Annual kWh	9,636 kWh	2,978 kWh
❌ Annual Cost	£2,539.09	—
✅ Annual Cost	—	£784.75

💷 Annual Saving: £1,754.34

📈 5-Year Saving: £8,771.70

⏱️ Payback Period: Typically under 6 months for commercial installations.

📍 Scenario: Doubling Filtration Time Without Increasing Costs

Variable speed technology enables dramatically extended filtration for superior water quality without higher electricity bills:

Traditional Single-Speed Approach:

• ❌ 8 hours at 1.8 kW = 14.4 kWh daily = £3.79/day

InverEco DE23 VS Approach:

• ✅ 16 hours at 50% speed (0.55 kW) = 8.8 kWh daily = £2.32/day

💵 Result: 39% lower daily cost despite doubling filtration time, delivering crystal-clear water with significant savings.

📍 Scenario: Capacity Comparison Within InverEco Range

For pools at the boundary between model recommendations, the DE23 offers substantial extra capacity:

Model	Power @ 60%	Flow @ 8m Head	Annual Cost (10hr/day, seasonal)	Best For
InverEco DE19 VS	~0.50 kW	19 m³/h	£237.15	30–50 m³ pools
InverEco DE23 VS	~0.68 kW	25 m³/h	£322.52	40–70 m³ pools

💵 Extra Capacity Premium: Only £85.37/year for 32% more flow—excellent value for larger installations or future expansion.
