Based on research conducted with UK universities on average 4m x 8m pools. Individual results vary depending on climate, usage patterns, water chemistry, and maintenance practices. See full disclaimers below.
🔥 Potential Payback Period: Less Than 12 Months*
Payback period assumes average UK energy rates, standard pool usage, and proper maintenance. Actual payback varies based on your specific circumstances.
✅ Why Choose Energy Guard Over Standard Solar Covers?
The Algae-Fighting Difference
Standard Clear Solar Covers:
- Allow all light through ☀️
- Feed algae growth 🦠
- Require constant chemical treatment 💊
- Mean more cleaning time 🧹
Energy Guard Selective Transmission:
- ✅ Blocks algae-feeding UV wavelengths with dark grey/black coating
- ✅ Still captures solar heat through selective transmission
- ✅ Reduces chemical use by up to 70%*
- ✅ Keeps water crystal clear with minimal intervention
Real-World Testing Proves It Works
In controlled university experiments, two identical pools ran for 10 days without chemicals or filtration:
- Pool with standard cover: Turned green within days
- Pool with Energy Guard: Remained algae-free for the entire test period (extended to 2+ months!)
🏊 Complete Feature Breakdown
Superior GeoBubble Technology (25% Longer Lifespan)
Unlike traditional bubble covers that fail at weak stress points, GeoBubble features:
- Twin-bubble design joined at the waistline with no sharp corners
- 50% greater material thickness than standard bubble covers
- Uniform thickness throughout – no thin or weak failure points
- Enhanced UV stabilization with advanced additive package
- Optimized air expansion capacity for better heat resistance
The result? Up to 25% longer lifespan compared to conventional bubble covers.
500M Thickness = Optimal Heat Performance
At 500 microns thick, this cover strikes the perfect balance between:
- ✓ Solar heat transmission (warms your pool by up to 4°C*)
- ✓ Heat retention (locks warmth in overnight)
- ✓ Durability (withstands chemical and UV exposure)
- ✓ Weight (easy to handle and deploy)
Temperature increase depends on sun exposure hours, ambient temperature, starting water temperature, and wind conditions.
💡 How Energy Guard Technology Works
1. Selective Light Transmission
The dark grey top surface and black underside work together to:
- Block photosynthesis-enabling light wavelengths that feed algae
- Absorb solar energy through heat-capturing dark pigmentation
- Transfer captured heat directly into the water below
2. Triple-Layer Protection
- Top layer: UV-stabilized dark grey material resists sun damage
- Bubble layer: GeoBubble air pockets insulate and retain heat
- Bottom layer: Black surface maximizes heat transfer to water
3. 98%+ Evaporation Barrier
By sealing your pool surface, Energy Guard:
- Prevents 32,000+ litres of water loss annually* (for a 4m x 8m pool)
- Stops chemical evaporation (saving up to 11kg of chlorine*)
- Reduces heat loss from evaporative cooling
🌍 Environmental Benefits (Plus You Save Money)
| Benefit | Environmental Impact | Your Savings |

| Energy reduction | Lower carbon footprint by 50%+ | £££ on heating bills |
| Water conservation | 32,000L saved = vital resource protection | £ on water charges |
| Chemical reduction | Less chlorine in wastewater systems | ££ on pool chemicals |
| 100% recyclable | Grade 4 LDPE – fully recyclable at end of life | Peace of mind |

- Use a roller system for easier handling (recommended for this size)
- Store carefully during winter months
- Maintain water temperature below 29°C for warranty validity
- Follow SPATA standards for chemical balance
❌ DON’T:
- Walk on the cover – it cannot support the weight of people or animals
- Use during harsh winter conditions (switch to a winter cover)
- Exceed maximum water temperature of 29°C
- Allow poor water chemistry (voids warranty)
- Leave exposed to extreme weather without proper securing
⚠️ Safety Warning
This is NOT a safety cover. It will not prevent drowning. If you have children or pets, consider adding a perimeter fence or upgrading to a certified safety cover system.
🤔 Common Questions Answered
“Will I still need to heat my pool?”
Yes. The Energy Guard captures solar heat and retains warmth brilliantly, but for consistent swimming temperatures (especially in cooler months), you’ll need a heating system. The good news? This cover reduces your heating costs by over 50%*, making your heat pump or heater far more efficient.
“Can I really cut chemical use by 70%?”
Research shows up to 70% reduction* is achievable because:
- Algae growth is physically blocked (not chemically controlled)
- 98%+ evaporation prevention keeps chemicals in the water
- Reduced photolysis reaction (90% of outdoor chlorine loss)
- Less pH correction needed without algae swings
Results based on university research with average 4m x 8m pools. Your actual savings depend on pool usage, climate, starting chemical regime, and maintenance practices.
“How do I know if this cover fits my pool?”
This cover is 14ft x 28ft (4.27m x 8.53m). Measure your pool’s length and width at the widest points. The cover should slightly overhang the edges for proper fit.
