For a 20ft x 40ft pool like yours, here’s what you could save annually*:

Cost Category	Without Cover	With Royal Blue 600M	Your Savings
Heating Energy	£1,200/year	£360/year	£840/year 💰
Water (Evaporation)	£180/year	£10/year	£170/year 💧
Chemicals	£250/year	£175/year	£75/year ⚡
TOTAL ANNUAL SAVINGS	—	—	£1,085/year ✅

Estimated payback period: 6-9 months based on typical UK pool usage (May-September).

🌡️ Why the Royal Blue 600M Outperforms Standard Covers

Premium 600-Micron Construction

At 600 microns thick, this is one of the most durable solar covers available. Compare that to basic 400M covers, and you’re getting:

• ✓ 50% more material thickness = Superior heat retention
• ✓ Better chemical resistance = Longer lifespan (25% longer than standard bubble covers)
• ✓ Enhanced UV protection = Won’t degrade or become brittle as quickly

Royal Blue: The Goldilocks of Pool Cover Colors

Not too light (like clear), not too dark (like black)—just right.

Cover Color	Solar Heating	Algae Prevention	Heat Retention	Best For
Clear	⭐⭐⭐⭐⭐	⭐⭐	⭐⭐⭐	Maximum heating
Royal Blue	⭐⭐⭐⭐	⭐⭐⭐⭐	⭐⭐⭐⭐⭐	Balanced performance
Dark/Opaque	⭐⭐	⭐⭐⭐⭐⭐	⭐⭐⭐⭐	Algae problems

Royal Blue achieves the perfect balance:

• Allows sufficient UV transmission to naturally warm your water by up to 8°C*
• Blocks enough light to inhibit algae growth
• Maximizes heat retention overnight when temperatures drop

🔥 GeoBubble™ Technology: Why It Matters

Standard bubble covers fail at the stress points where bubbles connect. GeoBubble™ redesigned the entire structure:

Traditional vs. GeoBubble Design

Traditional Bubble Covers: ❌ Thin connection points fail first
❌ Tears and punctures within 2-3 seasons
❌ Loses effectiveness as it degrades

GeoBubble™ Technology: ✅ Two-thirds of material in the bubble itself
✅ Scientifically designed curves eliminate stress points
✅ Lasts 25% longer than conventional covers
✅ Superior resistance to UV, chemicals, and temperature extremes

Translation: Your investment lasts longer, performs better, and saves you more money over time.

💧 The Hidden Cost of an Uncovered Pool

Water Loss You Can’t See (But Definitely Pay For)

An uncovered 20ft x 40ft pool loses approximately 32,000 litres per year to evaporation. That’s:

• 🚰 400 full bathtubs of water
• 💰 £150-180 annually in water costs
• 🌡️ Massive heat loss (evaporation is a cooling process)
• ⚗️ Chemical depletion requiring constant rebalancing

This cover reduces evaporation by 98%+, meaning you’ll add water once or twice per season instead of weekly.

⚡ Energy Savings That Actually Matter

How It Works: Your Pool as a Solar Collector

The Royal Blue 600M cover functions like a greenhouse roof:

1. ☀️ Capture: Royal Blue absorbs and transmits solar energy into the water
2. 🔒 Trap: Air-filled GeoBubbles create an insulating barrier (bubbles face DOWN into the water)
3. 🌡️ Retain: Prevents heat from escaping overnight—up to 75% reduction in heat loss*

Real-World Scenario:

Without a cover: Your pool heater runs 6-8 hours daily to maintain 26°C
With Royal Blue 600M: Your heater runs 2-3 hours daily for the same temperature

That’s a potential savings of up to 7,000 kWh per year* when combined with a modern heat pump—equivalent to £1,400+ at current UK electricity rates.

🤔 Common Questions Answered

Will I still need to heat my pool?

Yes. While the Royal Blue 600M provides significant solar gains (up to 8°C in optimal conditions), it works best alongside a heating system. Think of it as a “force multiplier”—it makes your heater far more efficient by retaining the heat it produces.

Best combination: Solar cover + heat pump = Maximum efficiency and lowest running costs.

How do I install it?

Simple: Unroll the cover over your pool with the bubbles facing DOWN into the water. The air-filled bubbles need direct contact with the water to transfer heat effectively. Secure the edges, and you’re done.

Can I run my pump with the cover on?

Absolutely. A properly secured cover won’t interfere with your pump’s circulation. Many pool owners leave their covers on during filtration cycles to maximize energy efficiency.

What about winter?

Solar covers aren’t designed for year-round use in UK weather. When closing your pool for winter (typically October-November), remove and carefully store your solar cover, then switch to a purpose-made winter cover for cold-weather protection.

Store your Royal Blue cover in a cool, dry place away from direct sunlight to ensure it’s in perfect condition when spring returns.

How long will this cover last?

With proper care, expect 4-6 years of reliable performance. GeoBubble technology extends lifespan by 25% compared to standard covers. Longevity depends on:

• Maintaining balanced pool chemistry (pH 7.2-7.6, chlorine 2-4 ppm)
• Removing the cover during shock chlorination
• Proper storage during winter months
• Avoiding chemical spills directly on the cover

💡 Care Tips for Maximum Lifespan

DO: ✅ Remove during shock chlorination (high chlorine levels degrade covers)
✅ Wait until chlorine returns to 2-4 ppm before replacing
✅ Rinse off any chemical spills immediately
✅ Store properly during winter (rolled, dry, out of sunlight)
✅ Keep pool chemistry balanced within SPATA guidelines

DON’T: ❌ Leave on during chemical shocking
❌ Allow pool temperature to exceed 29°C
❌ Drag the cover across rough surfaces
❌ Store wet or in direct sunlight during off-season
❌ Use harsh cleaners or solvents on the cover

⚠️ Important Disclaimers

Savings Calculations:
*All savings figures are estimates based on typical scenarios for a 20ft x 40ft pool used seasonally (May-September) in the UK. Actual savings depend on multiple factors including: local energy rates, pool usage patterns, climate conditions, existing heating system efficiency, water chemistry maintenance, and how consistently the cover is used. Heat pump electricity savings assume combination with a modern heat pump system. Individual results will vary.

Performance Metrics:
*Temperature increases up to 8°C, evaporation reduction of 98%+, heat loss reduction up to 75%, and energy savings up to 70% are based on optimal conditions including: full sun exposure, proper installation (bubbles facing down), consistent daily use, balanced water chemistry, and appropriate pool-to-cover size ratio. Actual performance varies with weather, pool location, shade, wind exposure, and maintenance practices.

Warranty Validity:
The 5-year pro-rata warranty applies only to UK & Eire customers and requires strict adherence to water chemistry standards (SPATA guidelines), temperature limits (not exceeding 29°C), and proper usage. Warranty is void if conditions are not met. This is not a safety cover and will not support weight.

ROI Timeframes:
Payback period estimates assume consistent use throughout the swimming season and typical UK energy costs as of 2025. Actual payback periods vary significantly based on individual circumstances. These are estimates, not guarantees.
