🔥 The Problem: Your Pool is Hemorrhaging Heat and Money

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

Without a proper heat retention cover:

• Heat loss through evaporation: Up to 70% of your pool’s heat escapes as water evaporates
• Radiative heat loss: Infrared radiation carries warmth away from the water surface
• Convective heat loss: Air movement constantly steals thermal energy
• Result: Your heating system runs constantly, burning through electricity while barely maintaining temperature

For a 20ft x 40ft pool, this means:

• Heating costs of £1,000-1,600 per season for uncovered pools
• 32,000+ litres of water lost to evaporation annually
• Chemical imbalances requiring constant rebalancing and additional chlorine
• Extended heat-up times making spontaneous swims impractical

The traditional solution? Expensive 5mm foam covers costing £1,500-2,500+ for this size pool. They work brilliantly but require significant upfront investment and can be cumbersome to handle.

---

✅ The Solution: RaeGuard 500M – Professional Heat Retention at Half the Cost

The RaeGuard 500M represents a breakthrough in pool cover technology: it delivers 90% of the heat retention performance of premium 5mm foam covers at a fraction of the price, while being significantly easier to handle and store.

How RaeGuard Works: Triple-Action Heat Protection

1. REFLECT 🔆
The specially engineered silver top layer and white bubble design reflect mid-infrared radiation back into your pool. Unlike standard solar covers that focus on UV transmission, RaeGuard’s pigments are precisely selected to bounce thermal radiation back down where it belongs – in your water.

2. INSULATE 🛡️
The unique GeoBubble air cell structure creates a substantial thermal barrier. Each air pocket acts as an insulating chamber, preventing heat transfer from your pool water to the cooler air above. Think of it as double-glazing for your pool.

3. ELIMINATE EVAPORATION 💧
By creating a physical barrier over the water surface, RaeGuard eliminates 98% of evaporation. This is crucial because evaporation is responsible for 70% of heat loss in uncovered pools. Stop the evaporation, stop the heat loss.

🔬 The Science Behind RaeGuard: Why It Works

Understanding Pool Heat Loss

Heat escapes from your pool through three mechanisms:

1. Evaporation (70% of heat loss)
   When water molecules evaporate, they carry massive amounts of thermal energy with them. For every litre that evaporates, your pool loses approximately 640 kWh of thermal energy.
2. Radiative Heat Loss (20% of heat loss)
   Your warm pool water emits infrared radiation into the cooler air and sky above – exactly like how you feel warmth radiating from a fireplace.
3. Convective Heat Loss (10% of heat loss)
   Air movement across the water surface constantly carries away warm air and replaces it with cooler air.

How RaeGuard Combats Each Mechanism

Against Evaporation:
The physical barrier eliminates 98% of water vapor escape, immediately cutting 70% of your total heat loss potential.

Against Radiative Loss:
The silver top layer contains specially selected pigments that reflect mid-infrared wavelengths (the “heat” part of the spectrum) back down into the pool. This is why RaeGuard outperforms clear or blue solar covers for heat retention – it’s engineered specifically for reflection, not transmission.

Against Convective Loss:
The GeoBubble air cell structure creates dead air spaces that prevent thermal conduction. Air is an excellent insulator when it’s trapped and still.

The GeoBubble Advantage:
Traditional bubble covers use round bubbles that are vulnerable to stress fractures and UV degradation. GeoBubble technology uses a patented two-joined-bubble design that distributes stress more evenly and is 25% more resistant to UV and chemical damage. This means your cover lasts 8+ years instead of 3-4 years.

❓ Frequently Asked Questions

General Performance

Q: How is RaeGuard different from regular solar pool covers?
A: Regular solar covers (like Sol+Guard or blue covers) are designed to heat your pool by transmitting UV rays through transparent material. RaeGuard is designed to retain heat by reflecting infrared radiation and providing superior insulation. Think of it this way: solar covers are for capturing free heat from the sun; RaeGuard is for keeping the heat you’ve already paid to generate.

Q: Can RaeGuard heat my pool water?
A: RaeGuard provides minimal solar heating gains because its silver-and-white design prioritizes reflection over transmission. If your primary goal is to heat your pool using solar energy, consider Sol+Guard 500M instead. RaeGuard excels at maintaining temperature, not raising it.

Q: Will this work with my heat pump?
A: Absolutely! RaeGuard is actually ideal for heat pump users. By reducing heat loss by 57%, your heat pump runs far less frequently, dramatically reducing your electricity consumption. Many heat pump owners report their systems running 50-60% less often after adding RaeGuard.

Q: How does RaeGuard compare to 5mm foam covers?
A: RaeGuard delivers approximately 90% of the heat retention performance of traditional 5mm foam covers at less than half the price. The trade-off is that foam covers retain slightly more heat (60%+ reduction vs. 57%), but RaeGuard is significantly lighter, easier to handle, and more affordable – making it the smarter choice for most pool owners.

Installation & Usage

Q: Which way do the bubbles face?
A: Bubbles should face DOWN, directly touching the water surface. This ensures the trapped air pockets can effectively insulate and transfer reflected heat into the water.

Q: Can I use this with my pool roller?
A: Yes! RaeGuard is compatible with standard pool roller systems. The lightweight design makes it much easier to roll and unroll than foam covers. For a 20ft x 40ft cover, a roller system is highly recommended for convenient daily use.

Q: Can I run my pool pump with the cover on?
A: Yes, absolutely. A properly secured RaeGuard cover will not interfere with your pump’s circulation system. In fact, we recommend leaving it on whenever the pool is not in use to maximize heat retention.

Q: How do I secure the cover to prevent wind lift?
A: For outdoor pools, use pool cover weights, water bags, or ropes with weights around the perimeter. The cover is lightweight, which makes handling easy but also means it needs proper anchoring in windy conditions.

Durability & Maintenance

Q: How long will this cover last?
A: With proper care, RaeGuard covers typically last 8+ years. The GeoBubble technology is 25% more resistant to UV and chemical damage than standard bubble covers. Key to longevity: remove the cover during winter months, store it properly when not in use, and avoid dragging it across rough surfaces.

Q: What’s the warranty?
A: RaeGuard comes with a 6-year pro-rata material warranty, which is excellent for a bubble-style cover and reflects the superior durability of GeoBubble technology.

Q: How do I clean the cover?
A: Simply rinse with fresh water and use a soft brush with mild soap if needed. Avoid harsh chemicals or pressure washers. Most pool owners find that regular hosing is sufficient to keep the cover clean.

Q: Can I use this in winter?
A: RaeGuard is designed for swimming season use (typically April-September in the UK). For winter pool closing, we recommend switching to a purpose-made winter cover that’s designed for debris protection and harsh weather. Store your RaeGuard properly during winter to extend its lifespan.

Cost & Value

Q: Is RaeGuard worth the investment for a seasonal pool?
A: Absolutely. Even with a 6-month season (April-September), typical savings of £650-900+ annually means your cover pays for itself in less than a year. Then it continues saving you money for 8+ years. Over its lifetime, a £703 investment can save you £5,000-7,000+.

Q: How much money will I actually save?
A: For a 20ft x 40ft heated pool, expect annual savings of £650-1,125+ depending on your heating costs, usage patterns, and local energy rates. The higher your current heating bills, the more you’ll save. Indoor pools and year-round heated pools see even better returns.

Q: What if my pool is a different size?
A: RaeGuard is available in multiple standard sizes, and custom sizes can be manufactured to order. Contact our team for sizing guidance and pricing for your specific pool dimensions.

Suitability

Q: Is this suitable for indoor pools?
A: Yes! RaeGuard was specifically designed with indoor pools in mind. Indoor pools experience high evaporation rates due to warm ambient temperatures, making heat retention covers essential for cost control. RaeGuard is lighter and easier to handle than foam covers while delivering 90% of the performance.

Q: Will this work for saltwater pools?
A: Yes, RaeGuard is compatible with chlorine, saltwater, and mineral pool systems. The GeoBubble material is resistant to chemical degradation.

Q: Can I use this for an above-ground pool?
A: RaeGuard works on above-ground pools, but ensure you have a proper securing system. Above-ground pools are more susceptible to wind lift due to their elevated position. Consider a cover roller or secure tie-down system.

Q: What if I have an unusual pool shape?
A: This particular listing is for a rectangular 20ft x 40ft cover. If you have an irregular shape, custom-cut covers can be manufactured to order. Use the pool cover calculator on the site or contact our team for assistance.
