🔥 What This Cover Will Do For Your Pool (And Your Wallet)

Your Annual Savings Breakdown:*

• Heating Costs: Save £400-600 per year by reducing heat loss by up to 75%
• Water Bills: Save approximately £80 by preventing 32,000 litres of evaporation (that’s 400 baths worth of water!)
• Chemicals: Save £60-100 by reducing chlorine consumption by up to 30% (5kg less chlorine annually)
• Time: Reclaim 15-20 hours per season that you’d spend cleaning debris and rebalancing chemicals

Total Annual Savings: £540-780*

Payback Period: Just 3-5 months based on typical UK pool running costs

*Your actual savings depend on pool usage, current energy rates, local climate, and existing heating system efficiency. Calculations based on average UK residential pool (20ft x 40ft), gas heating at £0.10/kWh, water rates at £2.50/m³, and chlorine at £12/kg. See detailed assumptions below.

❄️ The Problem: Your Pool Is Haemorrhaging Heat and Money

Every night your pool sits uncovered, you’re literally watching your money evaporate into the air:

• 75% of heat loss occurs through the water surface via evaporation
• 32,000 litres of water disappear annually from a pool this size – enough to fill 400 bathtubs
• Chlorine depletes 2-3x faster when exposed to UV rays and debris contamination
• Your heating system runs constantly trying to maintain comfortable temperatures, burning through energy

Without a cover, you could be spending £800-1,200 per year just keeping your pool warm enough to use.

Sound familiar? There’s a better way.

✅ The Solution: GeoBubble Technology That Works Smarter, Not Harder

The Blue 400M GeoBubble Solar Cover is engineered specifically for UK pool owners who want professional-grade performance without the premium price tag.

How It Works: Science You Can Feel

1. Bubble Design Traps Heat Like a Greenhouse The distinctive bubble structure (bubbles face down into the water) creates thousands of tiny air pockets that act as insulation. When the sun heats these air chambers, warmth transfers directly into your pool water while preventing overnight heat escape.

2. Blue Tint = Smart Temperature Control Unlike clear covers that can overheat water, the blue tint provides optimal balance: allowing beneficial UV penetration for solar heating while blocking excessive heat buildup and providing moderate UV protection for your pool chemicals.

3. 400-Micron Thickness = Durability Meets Efficiency At 400 microns thick, this cover hits the sweet spot: substantial enough to retain heat effectively and resist UV degradation, yet lightweight enough for easy handling and storage. The GeoBubble technology extends lifespan by 25% compared to traditional bubble covers.

4. Prevents Evaporation at the Molecular Level By creating a physical barrier over the water surface, the cover eliminates up to 98% of evaporation – the single biggest cause of heat loss and water waste in swimming pools.

🌡️ Real-World Performance: What You’ll Actually Experience

Temperature Retention

• Overnight heat retention: Keep 75% more warmth in your pool instead of losing it to the air
• Water temperature boost: Gain up to 8°C in optimal sunny conditions (summer days with 6+ hours of direct sunlight)
• Extended swimming season: Start using your pool 2-4 weeks earlier in spring and continue 2-4 weeks later into autumn

Cost Savings Breakdown

Energy Savings: If you currently spend £600/year heating your pool, expect to reduce this to approximately £180-240 per year – a saving of £360-420 annually.

Water Conservation: At UK average water rates (£2.50/m³), preventing 32,000 litres of evaporation saves you approximately £80 per year. More importantly, in drought-conscious areas, this is 400 baths worth of water you’re not wasting.

Chemical Efficiency: Pool chemicals (especially chlorine) break down rapidly when exposed to UV light and when diluted by constant water top-ups. By covering your pool:

• Use approximately 5kg less chlorine per year (£60-100 saving)
• Reduce pH adjuster and algaecide usage by 20-30%
• Spend far less time testing and rebalancing water chemistry

🎯 Why GeoBubble Technology Matters

Traditional round bubble covers have a fatal flaw: stress points at the bubble edges where the thin film connects to the flat surface. These stress points are where covers tear, split, and fail prematurely.

GeoBubble’s patented design eliminates these stress points with:

• Interconnected wavy bubble shapes that distribute stress evenly
• Thicker connection points that resist tearing
• 25% longer lifespan than traditional covers
• Better resistance to UV degradation and chemical exposure

Translation: Your cover lasts 1-2 years longer, saving you replacement costs and hassle.

📋 Frequently Asked Questions

Q: How long will this cover last? A: With proper care and storage, expect 5-6 years of reliable use. The GeoBubble technology and 4-year warranty provide confidence in longevity. Factors affecting lifespan include UV exposure, chemical balance, and handling care.

Q: Can I cut this cover to fit my pool shape? A: Yes! While it’s designed for rectangular pools, you can trim it to fit around steps, features, or to resize for smaller pools. Use sharp scissors and cut slowly for clean edges.

Q: Do the bubbles really need to face down? A: Yes – absolutely. The bubbles face down so that the sun heats the air trapped inside them, which then directly transfers heat into the water. Bubbles facing up won’t work effectively.

Q: Will this work with my heat pump/gas heater/solar heating? A: Yes! In fact, a solar cover makes ANY heating system more efficient by retaining the heat it produces. You’ll run your heater less often, saving money regardless of heating type.

Q: Can I leave it on when the pump is running? A: Yes, your pump can run with the cover on. However, remove the cover before using the pool for swimming and before shocking or adding large amounts of chemicals.

Q: How much does this weigh? Can one person handle it? A: For a 20ft x 40ft cover, expect approximately 25-30kg when dry. One reasonably fit adult can handle it, but a roller system makes it significantly easier and is highly recommended.

Q: What about winter – can I use this year-round? A: No. Solar covers are designed for swimming season (roughly April-October in UK). When closing your pool for winter, remove and store this cover properly, and use a dedicated winter cover for cold-weather protection.

Q: Does blue block too much sun for heating? A: No – blue covers still allow excellent UV transmission for solar heating while providing some chemical protection. If maximum solar gain is your priority, consider the clear Sol+Guard cover instead, but blue is the best all-rounder.

Q: Is it really made to order? A: Yes – your cover is manufactured fresh to ensure you receive a product with maximum remaining lifespan. Please allow appropriate manufacturing time (typically 1-2 weeks).

Q: What if it doesn’t fit perfectly? A: All covers can be trimmed for perfect fit. We recommend initially ordering to the nearest larger standard size, then trimming if needed. Bespoke sizes are also available for non-standard pool dimensions.
