TOTAL ANNUAL SAVINGS	£775-1,080	Covers typically pay for themselves in 8-12 months

*Based on UK average energy rates (£0.24/kWh), water rates (£3.70/m³), and typical chemical costs. Individual results vary based on pool usage, local climate, and maintenance practices.

🔬 The Science Behind Algae-Free Water

Why Other Pool Covers Let Algae Win

Traditional clear or light-colored solar covers do one job well—they heat your water. But they also do something terrible: they create the perfect greenhouse for algae growth. Sunlight + warm water + nutrients = green pool nightmare.

How Energy Guard Changes Everything

The Energy Guard uses Selective Transmission Technology—a revolutionary approach that gives you the best of both worlds:

✅ Dark Grey Top Surface – Blocks the specific light wavelengths algae needs for photosynthesis
✅ Black Underside – Absorbs solar energy and transfers heat directly to your water
✅ 500M Thickness – Provides superior insulation and durability
✅ GeoBubble Technology – Lasts 25% longer than standard bubble covers

The result? You get excellent solar heating (up to 4°C temperature increase) WITHOUT feeding algae growth.

🧪 University-Tested, Real-World Proven

The 10-Week Algae Challenge

UK university researchers conducted a head-to-head comparison:

• Pool 1: Standard clear solar cover
• Pool 2: Energy Guard cover

Test conditions: Both pools received simulated use, NO chemical treatment, NO filtration.

Results after 10 days:

• Standard cover pool: Turned completely green with algae
• Energy Guard pool: Crystal clear, zero algae growth

The test continued for 10 MORE WEEKS – the Energy Guard pool remained algae-free the entire time.

This isn’t marketing hype. This is peer-reviewed science proving what Energy Guard owners experience every day.

🤔 Frequently Asked Questions

How does Energy Guard prevent algae without chemicals?

Algae requires light for photosynthesis—specifically, certain wavelengths of UV light. Energy Guard’s opaque grey/black design physically blocks the wavelengths algae needs while still allowing heat-generating energy to pass through. No light for algae = no algae growth. This is why university tests showed Energy Guard pools remained algae-free for 10 weeks WITHOUT any chemicals or filtration.

Will I still need to use ANY chlorine?

Yes, but far less. Energy Guard dramatically reduces your chemical needs—up to 70% less—but you’ll still need basic sanitization for bacteria, contaminants from swimmers, and general water quality. Think of it as reducing your chlorine from £300/year to £90/year, not eliminating it entirely.

Can it heat my pool as well as a clear cover?

Energy Guard provides excellent solar heating (up to 4°C increase), though slightly less than ultra-clear covers like Sol+Guard (which achieve up to 8°C). The trade-off: Sol+Guard heats faster but can promote algae growth. Energy Guard heats well while PREVENTING algae. Most pool owners find this trade-off highly worthwhile—you get good heating without the green water problem.

How much will I actually save in the first year?

Based on typical UK pool ownership costs for a 20ft x 40ft pool, expect £775-1,080 in first-year savings* across heating (£420-580), chemicals (£180-240), filtration electricity (£95-140), and water bills (£80-120). Most covers pay for themselves within 8-12 months, then deliver pure savings for years 2-7+.

What if my pool water sometimes exceeds 29°C?

The warranty becomes void if water regularly exceeds 29°C because extreme heat can degrade the cover material faster. In the UK, this is rarely an issue except perhaps during heat waves in fully exposed pools. If you have an exceptionally hot pool (unusual in UK climate), consider whether you need that much heat—you might actually reduce heating costs by maintaining cooler, more comfortable temperatures!

How does GeoBubble make this cover last longer?

Traditional bubble covers have thin weak points where bubbles connect—these areas fail first from UV exposure, heat, and chemical attack. GeoBubble’s patented design connects two bubbles at a thick “waistline” with no thin spots, providing 50% more material at connection points. This uniform thickness means no weak links, resulting in 25% longer lifespan (typically 5-7 years vs. 3-4 years for standard covers).

Can I run my pool pump with the cover on?

Absolutely! Energy Guard won’t interfere with water circulation. However, one of Energy Guard’s major benefits is that you can REDUCE pump runtime by up to 50% because algae prevention means you don’t need as much filtration. This is where significant electricity savings come from—your pump still works, but you run it 5-6 hours daily instead of 10-12 hours.

Does this cover provide any safety protection?

No. Like all solar/bubble covers, Energy Guard cannot support the weight of children or pets and should never be relied upon as a safety device. If safety is a concern (especially with young children), install a pool fence or consider a dedicated safety cover. Energy Guard is for heat retention, algae prevention, and cost savings—not safety.

What about debris and leaves?

Energy Guard provides excellent debris protection. The solid opaque surface prevents leaves, insects, pollen, bird droppings, and other contaminants from entering your water. This keeps your pool cleaner and reduces the organic material that algae feeds on—a double benefit for water quality.

How do I store it during winter?

Energy Guard is designed for swimming season use (April-October in UK). During winter, replace it with a proper winter cover and store Energy Guard in a cool, dry location away from direct sunlight. Clean and dry it thoroughly before storage to maximize lifespan. Proper off-season storage helps ensure your cover lasts the full 5-7 years.

Will the dark color make my pool look uninviting?

This is subjective, but most owners appreciate the sleek, professional appearance of the grey/black design. More importantly, when you REMOVE the cover for swimming, your water will be crystal clear and inviting—unlike pools with clear covers that often have cloudy, greenish water. The trade-off of a darker covered appearance for pristine swimming water is overwhelmingly positive for most users.

Can I use this with a roller system?

Yes! Energy Guard is fully compatible with pool roller systems, making it easy to deploy and remove. At 500M thickness, it’s robust enough for regular use but still light enough for convenient handling. Many owners use rollers to make daily cover management effortless.

What if the standard size doesn’t fit my pool perfectly?

Parts4Tubs offers made-to-measure covers for non-standard pool sizes. Use their solar cover calculator to determine exact measurements, and they’ll manufacture a custom cover to ensure a perfect fit. Proper sizing is crucial for optimal performance—you want minimal gaps for best heat retention and algae prevention.

Is this environmentally friendly?

Absolutely! Energy Guard reduces your pool’s carbon footprint through:

• 50%+ reduction in heating energy (lower CO₂ emissions)
• 50% reduction in pump electricity (additional energy savings)
• 98% water conservation (preserves precious resources)
• 70% chemical reduction (fewer chemicals manufactured and transported)
• 100% recyclable material (Grade 4 LDPE recycling)

Over its 5-7 year lifespan, one Energy Guard cover prevents thousands of pounds of CO₂ emissions while conserving tens of thousands of litres of water.
