🔥 The Problem: Your Pool Is Haemorrhaging Heat and Money

If you’re running a heated pool without proper heat retention, you’re essentially heating the atmosphere. Here’s what’s happening right now:

Every 24 hours your uncovered pool loses:

• Up to 75% of its heat through evaporation, radiation, and convection
• 87 litres of water (enough for a bath)
• £1.50-£2.50 in heating costs
• Valuable chlorine and other chemicals

Over a typical 6-month swimming season, that means:

• £450-£750 in completely wasted heating costs
• 16,000+ litres of water down the drain
• Constant chemical rebalancing and frustration
• A pool that’s never quite warm enough when you want to swim

Sound familiar? There’s a better way.

✅ The Solution: Engineered Heat Retention Technology

The RaeGuard 500M GeoBubble Solar Cover isn’t just another pool blanket – it’s a precision-engineered thermal barrier designed specifically to lock in heat and slash your running costs.

How RaeGuard Technology Works:

1. REFLECT: Silver-Coated Heat Mirror The specially formulated silver top layer reflects mid-infrared radiation (heat) back into your pool instead of letting it escape into the atmosphere. Think of it as a thermal mirror that bounces heat waves back where they belong.

2. INSULATE: GeoBubble Air Cell Barrier Unlike ordinary bubble covers that use round bubbles, the patented GeoBubble design creates thousands of interconnected air cells that form a superior insulation layer. These cells trap still air – one of nature’s best insulators – creating a thermal barrier 90% as effective as traditional 5mm foam covers.

3. ELIMINATE: Evaporation Control When your pool is covered with RaeGuard, water molecules can’t escape as vapour. This eliminates up to 98% of evaporation – the single biggest source of heat loss in any pool.

The Result: Up to 57% reduction in heating costs compared to an uncovered pool, with performance approaching expensive foam covers at a fraction of the cost.

🛡️ GeoBubble Technology: Why It Matters

Not all bubble covers are created equal. Standard solar covers use simple round bubbles that develop weak points at stress areas, leading to premature failure.

GeoBubble Design Advantages:

1. No Weak Points The unique interconnected bubble shape eliminates the thin, stressed areas where traditional bubble covers tear and fail.

2. 25% Longer Lifespan Independent testing proves GeoBubble covers last at least 25% longer than conventional bubble designs – that’s why RaeGuard comes with an industry-leading 6-year pro-rata warranty.

3. Superior Material Distribution The GeoBubble shape distributes material more evenly across the cover, creating better insulation and more consistent performance across the entire pool surface.

4. Enhanced UV & Chemical Resistance Purpose-formulated polymer compounds resist degradation from both UV radiation and pool chemicals, maintaining performance year after year.

Expected lifespan: 8+ years (vs. 3-5 years for standard covers)

🌍 Environmental Impact: More Than Just Savings

Making eco-conscious choices for your pool doesn’t mean sacrificing performance. RaeGuard delivers measurable environmental benefits:

Annual Environmental Savings:

• 32,000 litres of water saved (equivalent to 400 baths, or 213 toilet flushes)
• 2,850-3,705 kWh electricity saved (equivalent to powering an average UK home for 3-4 months)
• 5kg less chlorine production & disposal (reducing chemical manufacturing impact)
• Reduced carbon footprint: 672-872 kg CO₂e annually (based on UK grid carbon intensity)

Your pool becomes significantly more sustainable while your wallet benefits from the savings.

🎯 Installation & Care Instructions

Proper Installation:

1. Bubble Side Down: Always place the cover with the white bubbles facing down toward the water. The silver reflective layer should face up toward the sky.
2. Secure Properly: Ensure the cover is properly secured to prevent wind damage. Consider a roller system for pools of this size (18ft x 36ft) for easier handling.
3. Cover Fit: This cover is made-to-measure for 18ft x 36ft pools. It should fit snugly across the water surface.
4. With Pool Equipment: It’s perfectly safe to run your pump and filter with the cover on. The water circulates underneath without issue.

Care & Storage:

During Swimming Season:

• Remove cover before swimming (obviously!)
• Keep cover clean by hosing off debris regularly
• Don’t allow cover to sit with standing water on top – use a cover pump if needed

Off-Season Storage:

• Clean thoroughly before storage
• Dry completely to prevent mould/mildew
• Fold or roll loosely and store in a cool, dry location
• Avoid prolonged exposure to direct sunlight when stored

Pro Tip: For a pool this size, investing in a roller system (available separately) makes daily cover handling much easier and extends cover life by reducing handling stress.

❓ Frequently Asked Questions

Q: Will this cover heat my pool on its own?

A: No – RaeGuard is designed primarily for heat retention, not solar heating. While it will prevent temperature loss, it won’t significantly raise water temperature through solar gain. For that, you’d want Sol+Guard (translucent design). RaeGuard works best when paired with a pool heater, preserving the heat your system generates.

Q: Can I use this cover year-round?

A: RaeGuard works brilliantly during the swimming season (typically April-October in the UK). For winter pool closure, we recommend switching to a dedicated winter cover designed for harsher conditions and long-term debris protection. Proper off-season storage will extend your RaeGuard cover’s lifespan significantly.

Q: How does the 57% savings figure work?

A: This figure comes from comparing a heated pool covered with RaeGuard versus the same pool left uncovered. The savings come from three sources: reduced evaporative heat loss (the biggest factor), reduced radiative heat loss (thanks to the reflective layer), and reduced convective heat loss (from the insulating air cells). Your actual savings will depend on your pool’s current temperature, local climate, heating system efficiency, and usage patterns.

Q: Will this work with my heat pump?

A: Absolutely! RaeGuard is ideal for heat pump users. Heat pumps are extremely efficient at generating heat, but that efficiency is wasted if heat escapes through evaporation. RaeGuard ensures your heat pump’s output stays in the pool, dramatically reducing runtime and electricity consumption.

Q: What about outdoor pools in full sun?

A: RaeGuard works well for outdoor pools, but it’s optimised for heat retention rather than solar gain. If your pool receives significant direct sunlight and you want to capture that free heating, consider Sol+Guard instead. However, if your pool is partially shaded, windy, or you primarily want to prevent overnight heat loss, RaeGuard is excellent.

Q: Is this cover safe for children and pets?

A: No. Like all bubble-style pool covers, RaeGuard is NOT a safety cover and cannot support the weight of a child or animal. It’s purely a thermal and evaporation barrier. If safety is a priority (especially with young children), you need a dedicated safety cover or perimeter fencing. Never rely on any bubble cover for safety.

Q: How do I clean and maintain it?

A: Simple! Hose off debris regularly during use. Occasionally use a soft brush with mild soap if needed. Avoid harsh chemicals or abrasive cleaning that could damage the reflective coating. The cover is designed to withstand pool chemicals in normal use, but prolonged contact with concentrated chemicals should be avoided.

Q: What if my pool size is slightly different?

A: This specific listing is for 18ft x 36ft. If your pool dimensions are different, Parts4Tubs offers bespoke sizing. Contact them with your exact measurements, and they’ll manufacture a RaeGuard cover to your precise specifications. Made-to-measure ensures optimal fit and performance.

Q: Can this replace a foam cover?

A: In most cases, yes! RaeGuard achieves approximately 90% of the heat retention performance of traditional 5mm foam covers, but costs less than half the price and is far easier to handle. For commercial pools or indoor pools where heat retention is absolutely critical, RaeGuard offers an excellent cost-effective alternative to heavy, expensive foam.

Q: How long will it take to receive my cover?

A: RaeGuard covers are made to order, with a lead time of approximately 15-20 working days from order placement. This ensures you receive a fresh, perfectly manufactured cover rather than warehouse stock that may have degraded over time.
