🎯 Real World Applications

🏊‍♂️ Large Residential Pools (50,000 – 75,000 Litres)

The 19m³/hr flow rate provides excellent turnover for substantial residential pools. A 60,000-litre pool achieves complete water turnover in approximately 3 hours – well within recommended 4-6 hour filtration cycles for optimal water clarity.

Ideal for: Large in-ground pools, luxury garden installations, family swimming pools

---

🏢 Light Commercial Applications

Hotels, holiday parks, and small leisure facilities benefit from the MJB 1.5HP’s combination of commercial-grade construction and single-phase simplicity. No three-phase electrical supply required, yet performance matches demanding usage patterns.

Ideal for: Boutique hotel pools, B&B installations, caravan park amenities, small gym facilities

---

🌊 Complex Water Features & Circulation Systems

Beyond primary filtration, the high flow capacity powers elaborate water features, multiple return jets, or auxiliary circulation loops. The quiet operation maintains ambiance even during feature pump operation.

Ideal for: Infinity edges, water walls, multiple fountain jets, spa spillovers

---

🔄 Direct Hydroswim HGS Replacement

Engineered with identical dimensions, mounting points, and connection specifications to the Hydroswim HGS151 series, the Vipool MJB slots directly into existing installations. No plumbing modifications, no electrical changes – simply disconnect and reconnect.

Ideal for: Failed Hydroswim replacements, planned upgrades, preventive swaps before 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 handles salt concentrations without degradation.

Ideal for: Salt chlorinator installations, automated dosing systems, mixed sanitisation approaches

---

♨️ Heated Pool Circulation

The continuous duty motor rating handles the extended operation times heated pools typically require. Year-round indoor installations benefit from the reliable, quiet performance during all seasons.

Ideal for: Indoor heated pools, pool-spa combinations, therapy pools

💡 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.

Factor	Old Worn Pump	New Vipool MJB
Estimated power draw	~1.40 kW (degraded efficiency)	1.10 kW
Annual energy (1,440 hrs)	2,016 kWh	1,584 kWh
❌ Old annual cost	£524.16	—
✅ New annual cost	—	£411.84
💰 Annual savings	—	£112.32

📈 5-Year Projection: £561.60 in energy savings alone, plus avoided emergency repair costs and improved reliability.

---

📍 Scenario: Upgrading from a Budget 1.5HP Pump

Budget pumps often consume significantly more power to deliver the same flow. Quality engineering pays dividends in reduced electricity bills.

Factor	Budget 1.5HP Pump	Vipool MJB 1.5HP
Power consumption	1.50 kW	1.10 kW
Annual energy (1,440 hrs)	2,160 kWh	1,584 kWh
❌ Previous annual cost	£561.60	—
✅ New annual cost	—	£411.84
💰 Annual savings	—	£149.76

⏱ Payback calculation: If the Vipool MJB costs £150 more than a budget replacement, energy savings alone recover the difference in approximately 12 months!

---

📍 Scenario: Right-Sizing from an Oversized 2HP Pump

Many pool owners discover their previous installer fitted an oversized pump. If your pool only requires 19m³/hr, running a 2HP pump wastes energy whilst providing no benefit.

Factor	Oversized 2HP Pump	Right-Sized MJB 1.5HP
Power consumption	1.50 kW	1.10 kW
Flow rate needed	19 m³/hr	19 m³/hr ✅
Annual energy (1,440 hrs)	2,160 kWh	1,584 kWh
❌ Oversized annual cost	£561.60	—
✅ Right-sized annual cost	—	£411.84
💰 Annual savings	—	£149.76

---

📍 Scenario: Commercial Installation – 10-Year Total Cost of Ownership

For commercial operators, long-term reliability and total cost matter more than initial purchase price.

Cost Element	Budget Pumps (3 replacements)	Vipool MJB (1 replacement)
Initial purchase	£350	£550
Replacements over 10 years	£1,050 (3 × £350)	£550 (1 × £550)
Energy (10 years × £562/yr)	£5,620	—
Energy (10 years × £412/yr)	—	£4,120
Downtime/call-out costs	~£600 (3 failures)	~£200 (1 planned swap)
Total 10-year cost	£7,620	£5,420
💷 Lifetime savings	—	£2,200
