🎯 Stop Wasting Money Heating Water That Just Evaporates Overnight

If you’re spending hundreds of pounds each swimming season just to keep your pool warm enough to enjoy, you’re literally watching your money evaporate into thin air.

Here’s what’s happening to your uncovered pool every single day:

❌ 32,000 litres of water evaporating annually (that’s 400 baths worth)
❌ 75% of your pool’s heat escaping overnight
❌ £500-700+ extra on heating bills per season*
❌ 30% more chemicals needed to rebalance after evaporation
❌ Hours spent cleaning debris instead of swimming

What if one simple addition could cut those costs by up to 70%?

✅ The Solution: Blue 400M GeoBubble Solar Cover

This budget-friendly yet highly effective solar cover uses proven GeoBubble technology to create an insulating barrier between your pool water and the environment. The result? Dramatically lower running costs and a pool that’s ready to swim in whenever you are.

🔥 How the Blue 400M GeoBubble Cover Works

The Technology Behind Your Savings

1. GeoBubble Design (25% Longer Lifespan)
Unlike standard bubble covers that develop weak points and tear easily, GeoBubble technology uses a scientifically designed bubble shape with no sharp edges or stress points. This means your cover lasts 25% longer than traditional designs.

2. 400-Micron Thickness
The 400M (micron) thickness strikes the perfect balance for budget-conscious pool owners:

• Thick enough to provide excellent heat retention
• Light enough to handle easily without mechanical rollers
• Durable enough to withstand UV exposure and chemical contact

3. Blue Tint Benefits
The blue tint isn’t just aesthetic:

• Provides moderate UV protection for your pool chemicals
• Reduces algae growth by limiting light penetration
• Maintains good solar heat transmission through the material
• Blends naturally with your pool water color

4. Air Bubble Insulation
Each air-filled bubble acts as a mini greenhouse:

• Traps heat from the sun during the day
• Prevents heat loss through evaporation at night
• Creates an insulating air layer between water and atmosphere
• Reduces water evaporation by up to 98%

---

💡 Why Choose the 400M Thickness?

Perfect For:

✅ Above-ground pools (easy to handle without mechanical assistance)
✅ Budget-conscious pool owners (excellent value for money)
✅ Pools without roller systems (lightweight enough for manual handling)
✅ First-time cover buyers (affordable introduction to pool covering benefits)
✅ Seasonal pools (great protection during active swimming months)

📊 Real-World Performance: 15ft x 30ft Pool Example

Pool Specifications:

• Size: 15ft x 30ft (4.5m x 9m)
• Volume: Approximately 50,000 litres
• Location: UK (moderate climate)
• Swimming season: April-September (6 months)

Without Blue 400M Cover:

💸 Heating Costs: £750/season (heat pump running 8-10 hours daily)
💧 Water Loss: 32,000 litres/season (£160 replacement cost)
🧪 Chemical Consumption: £200/season (frequent rebalancing)
🧹 Maintenance Time: 4+ hours/month cleaning debris

With Blue 400M Cover:

💰 Heating Costs: £250/season (70% reduction) = £500 saved
💧 Water Loss: 3,000 litres/season (98% reduction) = £145 saved
🧪 Chemical Consumption: £140/season (30% reduction) = £60 saved
🧹 Maintenance Time: 1 hour/month = 3 hours saved monthly

Total First-Season Savings: £705*

After cover cost is recovered (typically 2-4 months), these become pure savings every season thereafter.

🔧 Installation & Usage Guide

How to Install Your Cover (Bubbles Down!)

Step 1: Unroll your cover beside the pool
Step 2: Position one edge at the pool’s edge
Step 3: Carefully pull across the water surface
Step 4: Ensure bubbles face DOWN into the water

Why bubbles down? The air trapped in the bubbles needs to be heated by the sun, then transfer that heat directly into your water. Bubbles facing down maximize this heat transfer.

Daily Use Tips

✅ Cover the pool immediately after swimming to trap residual heat
✅ Remove before swimming (never allow anyone to walk on the cover)
✅ Use during the day for maximum solar gain (remove if water is already warm enough)
✅ Cover overnight to prevent heat loss through evaporation
✅ Keep covered during cooler/windy days to maintain temperature

Can You Run Your Pool Pump with the Cover On?

YES! Your filtration system can run normally with the cover in place, as long as it’s properly secured and doesn’t obstruct the skimmer or other equipment.

Seasonal Storage

Spring/Summer (April-September): Active use on pool surface

Autumn/Winter (October-March):
❌ Do NOT use as a winter cover (not designed for harsh winter conditions)
✅ Clean thoroughly before storage
✅ Dry completely to prevent mildew
✅ Roll loosely and store in a dry, protected area
✅ Avoid folding (can create permanent creases)

For winter protection, invest in a purpose-built winter cover to protect your pool during the off-season.

❓ Frequently Asked Questions

How much will this cover actually save me?

Based on a 15ft x 30ft pool, expect to save £600-800 annually on heating, water, and chemicals combined. Your exact savings depend on:

• Your current heating method (heat pump vs. gas vs. electric)
• Local energy rates
• Swimming season length
• Pool usage frequency
• Local climate conditions

How long will the Blue 400M cover last?

With proper care and seasonal storage, expect 4-5 years of reliable performance. The GeoBubble technology extends lifespan by 25% compared to standard bubble covers. Your cover comes with a 4-year material warranty from the manufacturer.

Is 400M thick enough for heat retention?

Absolutely! The 400M thickness provides 60-65% heat retention, which translates to significant savings. While thicker covers (500M, 600M) offer incrementally better performance, the 400M delivers excellent value and is specifically designed for budget-conscious pool owners and above-ground applications.

Can I walk on this cover?

NO – Never walk on any solar pool cover. These covers are designed for heat retention and debris protection, NOT for supporting weight. Walking on the cover can:

• Damage the material and void your warranty
• Create a serious safety hazard
• Cause the person to fall into the pool

If safety is a concern (children, pets), consider adding a perimeter fence or upgrading to a dedicated safety cover.

Will this cover heat my pool on its own?

The Blue 400M cover can raise water temperature by up to 8°C in optimal conditions through solar gain. However, for comfortable swimming in the UK climate, you’ll still need a primary heating source (heat pump, gas heater, or solar panels).

The cover’s real superpower is retaining that heat, making your heating system work 70% less while maintaining comfortable temperatures.

How heavy is this cover? Can I handle it alone?

The 15ft x 30ft Blue 400M cover weighs approximately 25kg when dry. Most adults can handle this size manually, though it becomes slightly heavier when wet. For easier handling, consider:

• Pool roller system (recommended for all covers)
• Second person assistance for initial placement
• Folding technique to make removal more manageable

Does the blue color matter?

Yes! The blue tint provides:

• Moderate UV protection for your chemicals
• Algae growth reduction by limiting light penetration
• Aesthetic appeal that complements blue pool water
• Good solar transmission for heating benefits

Clear covers offer slightly better solar gain, while darker covers (like Energy Guard) offer maximum algae prevention.

Can I leave this on while the pool pump runs?

Yes, your filtration system can operate normally with the cover in place. Just ensure the cover is properly secured and doesn’t obstruct your skimmer or return jets.

What if my pool isn’t exactly 15ft x 30ft?

No problem! Parts4Tubs offers bespoke sizing for any pool dimensions. Use the solar cover calculator on the website to specify your exact measurements for a custom-made cover that fits perfectly.

How do I clean and maintain the cover?

Regular maintenance (monthly):

• Rinse with clean water to remove debris
• Use a soft brush for stubborn dirt
• Avoid harsh chemicals or abrasive cleaners
• Allow to dry completely before storing temporarily

End-of-season storage:

• Clean thoroughly and allow to dry completely
• Roll loosely (never fold)
• Store in a dry, protected location away from rodents
• Keep out of direct sunlight during storage

Is this better than a winter cover?

They serve different purposes:

• Solar covers (like this 400M): Heat retention, evaporation prevention, debris protection during swimming season
• Winter covers: Durable mesh designed for harsh weather, heavy debris, and long-term closure

You need BOTH: Use the solar cover during swimming season (April-September), then switch to a winter cover for the off-season (October-March).
