⚡ Energy Efficiency Comparison
The Vipool MJB’s 0.75 kW power draw demonstrates exceptional efficiency for a 1HP pump. Quality engineering maximises hydraulic output whilst minimising electrical waste.
| Pump Type | Typical Power Draw | Annual Cost (1,440 hrs) | Difference |
|---|---|---|---|
| ✅ Vipool MJB 1HP | 0.75 kW | £280.80 | — |
| ❌ Older Single-Speed 1HP | 0.95 kW | £355.68 | +£74.88/year |
| ❌ Budget 1HP Pump | 1.10 kW | £411.84 | +£131.04/year |
| ❌ Oversized 1.5HP (unnecessary) | 1.10 kW | £411.84 | +£131.04/year |
💡 Pro Tip: Choosing the right-sized pump saves more than oversizing! A 1HP pump for a 45,000L pool is more efficient than running a 1.5HP at partial capacity.
🎯 Real World Applications
🏠 Medium Residential Pools (35,000 – 55,000 Litres)
The 14m³/hr flow rate provides excellent turnover for typical family pools. A 45,000-litre pool achieves complete water turnover in approximately 3.2 hours – comfortably within the recommended 4-6 hour daily filtration cycle for crystal-clear water.
Ideal for: Standard in-ground pools, family garden pools, typical UK residential installations
🔄 Direct Hydroswim HGS Replacement
Engineered with identical dimensions, mounting points, and connection specifications to the Hydroswim HGS101 series, the Vipool MJB slots directly into existing installations. Simply disconnect the old pump and connect the new one – no plumbing modifications required.
Ideal for: Failed Hydroswim replacements, planned upgrades, preventive swaps before pool season
🧂 Salt Water & Chlorinated Pool Systems
Full compatibility with all sanitisation methods including salt chlorinators, standard chlorine, bromine, and mineral systems. The corrosion-resistant construction and stainless steel components handle salt concentrations without degradation.
Ideal for: Salt chlorinator installations, automated dosing systems, mixed sanitisation approaches
🌊 Water Features & Auxiliary Circulation
Beyond primary filtration, the reliable 14m³/hr flow powers moderate water features, spillovers, and auxiliary circulation loops. The quiet operation maintains poolside ambiance during feature operation.
Ideal for: Decorative water features, gentle spillovers, secondary circulation duties
🏡 Holiday Homes & Rental Properties
The combination of reliability, efficiency, and straightforward maintenance makes this pump ideal for properties where the owner isn’t always present. The quality construction minimises call-out risks during peak rental season.
Ideal for: Holiday lets, Airbnb properties, second homes, rental pool properties
♨️ Pool-Spa Combinations
For installations with both a main pool and attached spa, the MJB 1HP handles the primary pool circulation whilst working in harmony with dedicated spa equipment.
Ideal for: Pool-spa combos, swimspa circulation, integrated wellness installations
💡 Cost Savings Examples
📍 Scenario: Replacing a Worn Hydroswim HGS
Ageing pumps lose efficiency as bearings wear, seals degrade, and motors work harder. Replacing a tired Hydroswim with a new Vipool MJB restores peak performance and cuts energy bills.
| Factor | Old Worn Pump | New Vipool MJB |
|---|---|---|
| Estimated power draw | ~1.0 kW (degraded efficiency) | 0.75 kW |
| Annual energy (1,440 hrs) | 1,440 kWh | 1,080 kWh |
| ❌ Old annual cost | £374.40 | — |
| ✅ New annual cost | — | £280.80 |
| 💰 Annual savings | — | £93.60 |
📈 5-Year Projection: £468 in energy savings alone, plus avoided emergency repair costs and improved reliability.
📍 Scenario: Upgrading from a Budget 1HP Pump
Budget pumps often consume significantly more power to deliver the same flow. Quality engineering pays dividends in reduced electricity bills.
| Factor | Budget 1HP Pump | Vipool MJB 1HP |
|---|---|---|
| Power consumption | 1.10 kW | 0.75 kW |
| Annual energy (1,440 hrs) | 1,584 kWh | 1,080 kWh |
| ❌ Previous annual cost | £411.84 | — |
| ✅ New annual cost | — | £280.80 |
| 💰 Annual savings | — | £131.04 |
⏱ Payback calculation: If the Vipool MJB costs £100 more than a budget replacement, energy savings alone recover the difference in approximately 9 months!
📍 Scenario: Right-Sizing from an Oversized 1.5HP Pump
Many pool owners discover their previous installer fitted an oversized pump. If your pool only needs 14m³/hr, running a 1.5HP pump wastes energy whilst providing no benefit.
| Factor | Oversized 1.5HP Pump | Right-Sized MJB 1HP |
|---|---|---|
| Power consumption | 1.10 kW | 0.75 kW |
| Flow rate needed | 14 m³/hr | 14 m³/hr ✅ |
| Annual energy (1,440 hrs) | 1,584 kWh | 1,080 kWh |
| ❌ Oversized annual cost | £411.84 | — |
| ✅ Right-sized annual cost | — | £280.80 |
| 💰 Annual savings | — | £131.04 |
📍 Scenario: New Pool Installation – 10-Year Total Cost Analysis
