🔥 Why Sol+Guard is Different: Maximum Solar Heating Performance
Most pool covers simply retain heat. Sol+Guard actively heats your water through advanced solar transmission technology.
The Translucent Advantage
Sol+Guard’s unique two-ply construction combines a crystal-clear top surface with a translucent tinted underside, creating the market’s most effective solar heating system in bubble cover form:
What Makes It Work:
- Clear top layer transmits maximum UV radiation (highest penetration rate of any GeoBubble cover)
- Translucent underside diffuses solar energy evenly across water surface
- GeoBubble air pockets trap and amplify heat before transferring to water
- Can raise pool temperature by up to 8°C through solar gain alone (verified by UK university testing)
Real-World Performance:
- Sunny day gains: 3-5°C temperature increase
- Partly cloudy: 1-3°C increase
- Overcast: Maintains temperature + prevents heat loss
- Night retention: Prevents 75%+ of overnight heat radiation
Compare: Sol+Guard vs Standard Covers
| Feature | Sol+Guard 500M | Standard Blue Cover | Opaque Energy Guard |
|---|---|---|---|
| Solar Transmission | Maximum (translucent) | Moderate (blue tint blocks some UV) | Minimal (blocks light for algae control) |
| Primary Function | Active solar heating + retention | Heat retention only | Heat retention + algae prevention |
| Temperature Gain Potential | Up to 8°C | Up to 4°C | Up to 2°C |
| Best For | Maximising free solar heating | Retaining existing heat | Pools with algae issues |
| Ideal Climate | UK (making most of limited sun) | Any climate | Warm, sunny climates |
The UK Advantage: Britain’s temperate climate actually benefits from Sol+Guard more than hotter regions. Why? You need active solar heating to extend your season, not just passive retention. Sol+Guard captures every available ray during those precious sunny British days.
🏊 What You Get: Engineering That Lasts 25% Longer

📊 The Complete Savings Breakdown: How Every Benefit Adds Up
1. Heating Energy Savings (£580-812/year)
The Problem: Heat loss occurs through three mechanisms:
- Evaporation (accounts for 70% of heat loss)
- Radiation to atmosphere (25% of loss)
- Conduction to surrounding surfaces (5% of loss)
The Solution: Sol+Guard addresses all three simultaneously while adding solar gain:
| Scenario | Uncovered Pool | With Sol+Guard | Annual Savings |
|---|---|---|---|
| Conservative (heat pump, May-Sept) | 3,500 kWh @ £0.24/kWh | 1,050 kWh | £588 |
| Typical (heat pump, extended season) | 4,200 kWh @ £0.28/kWh | 1,260 kWh | £823 |
| Optimal (solar gain offsetting needs) | 3,500 kWh @ £0.24/kWh | 735 kWh | £663 |
Based on 70% reduction in heating requirements plus active solar gains offsetting artificial heating needs on sunny days.
2. Water Conservation Savings (£141/year)
The Evaporation Crisis:
- Average UK pool (4m x 8m): 32,000 litres lost annually
- Your 14ft x 28ft pool: Similar loss rate (approximately 32,000L)
- That’s 400 baths worth of treated, heated water
- Current UK water costs: £4.40 per cubic metre (includes supply + sewerage)
With Sol+Guard:
- Eliminates 98%+ of evaporation
- Saves 31,360 litres (98% of 32,000L)
- Annual water savings: 31.36m³ × £4.40 = £138.02
- Bonus: Less frequent top-ups = less time balancing chemistry
Hidden Benefit: Every litre of evaporated water carries heat away. Preventing evaporation prevents heat loss—a double benefit already factored into heating savings above.
3. Chemical Savings (£45-75/year)
Why Chemicals Disappear Faster Without a Cover:
- Evaporation carries chlorine out of solution
- UV radiation degrades sanitiser molecules
- Debris consumes chlorine fighting contamination
- Temperature fluctuations stress chemical balance
Research-Backed Results:
- 30% reduction in chemical consumption (UK university studies)
- Typical pool: 17kg chlorine annually → 11.9kg with cover
- Savings: 5.1kg chlorine @ £9-15/kg = £45-75/year
- Additional savings on pH adjusters, algaecides, clarifiers
Real-World Impact: Fewer trips to the pool shop, less time testing and dosing, more stable water chemistry, better swimming experience.
4. Equipment Longevity (£150+/year in deferred costs)
The Wear-and-Tear Factor:
Your heat pump, filter system, and chemical dosing equipment all work harder when your pool is uncovered:
- Heat pump compressor: Reduced runtime by 70% = extended lifespan by years
- Filter system: Less debris = less strain, longer intervals between media replacement
- Pipes and fittings: More stable water chemistry = less corrosion
- Pool surface: Protected from UV damage and debris scratching
Conservative Estimate: If Sol+Guard extends your heat pump life from 12 years to 15 years (a modest 25% extension), that’s deferring a £2,000-3,000 replacement by 3 years—worth approximately £150-200 annually in present value terms.
🌍 Environmental Benefits: Reducing Your Pool’s Carbon Footprint
Pool ownership comes with environmental responsibilities. Sol+Guard helps you enjoy your pool sustainably:
Annual Carbon Reduction:
- Energy savings: 2,450 kWh × 0.23 kg CO₂/kWh = 563 kg CO₂ prevented
- Water conservation: 31,360L reduces pressure on water treatment infrastructure
- Chemical reduction: Less chlorine production = lower manufacturing emissions
- Recyclability: 100% LDPE recyclable at end of 6+ year life
Context: 563 kg CO₂ saved annually equals:
- Driving 1,400 miles in an average petrol car
- 2.5 return flights London to Edinburgh
- Running a refrigerator for 18 months
❓ Common Questions About Sol+Guard Solar Covers
“Will I still need to run my heat pump?”
Yes, but far less frequently. Sol+Guard is designed to work in tandem with your existing heating system, not replace it:
- Sunny days: Solar gains may heat pool sufficiently (heat pump stays off)
- Cloudy days: Heat pump runs less due to retained heat overnight
- Season extension: Start swimming earlier in spring, continue later in autumn
- Consistent comfort: Combine both systems for reliable temperature control
Think of it this way: Sol+Guard is like loft insulation for your pool—massively reducing heating bills while your boiler (heat pump) provides backup when needed.
“How much solar heating can I actually expect in the UK?”
Realistic expectations for British weather:
May-June (spring):
- Sunny days: +3-5°C temperature gain
- Partly cloudy: +1-2°C gain
- Rainy days: Maintains temperature (prevents loss)
July-August (peak summer):
- Sunny days: +4-6°C gain (can achieve 8°C in optimal conditions)
- Partly cloudy: +2-3°C gain
- Even overcast days: Prevents heat radiation, maintaining warmth
September (late season):
- Sunny days: +2-4°C gain
- Cloudy days: Heat retention becomes primary benefit
- Extends swimming season by 2-4 weeks
University-Verified: The “up to 8°C” specification comes from controlled testing at two UK universities. Real-world results typically range 2-6°C depending on weather, with peak gains on sunny, calm days.
“Is 500M thickness enough, or should I get 600M?”
500M is the optimal thickness for solar heating:
Sol+Guard 500M (this product):
- ✅ Best solar transmission (thinner = more UV penetration)
- ✅ Excellent heat retention for nighttime/cloudy periods
- ✅ 6+ year lifespan with proper care
- ✅ Lightweight for easy handling (important for daily use)
- ✅ Best value for money (lower price, maximum solar gain)
600M Gold covers (alternative product):
- ✅ Maximum heat retention (thicker = better insulation)
- ✅ Longer lifespan (7-8+ years)
- ✅ Premium durability
- ❌ Reduced solar transmission (thicker material blocks some UV)
- ❌ Heavier (harder to handle daily)
- ❌ Higher cost (£100-200+ more for similar size)
Best Choice: If your priority is active solar heating to warm your pool naturally, Sol+Guard 500M is scientifically proven to deliver maximum temperature gains. Choose 600M only if you primarily need heat retention for an already-heated pool.
“Won’t the clear material cause algae growth?”
No—the translucent underside prevents this problem:
Sol+Guard’s clever design allows UV through for heating while managing algae risk:
- Top layer: Clear for solar penetration
- Underside: Translucent tinted (not fully transparent)
- Result: Enough light blocked to prevent photosynthesis on cover surface
- Chemical balance: Maintained by regular sanitiser levels (which you’re already using)
When algae becomes a concern: If your pool has persistent algae issues unrelated to the cover, consider Energy Guard 500M instead—it uses selective transmission technology to block algae-causing wavelengths while allowing heating UV through.
Reality check: Thousands of UK pool owners use clear/translucent covers successfully. Proper water chemistry matters far more than cover colour for algae control.
“Will it work with my automatic roller?”
Yes, Sol+Guard is fully compatible with standard pool cover rollers:
- Lightweight design (≈11kg) rolls easily
- GeoBubble material resists cracking during rolling
- Works with manual or automatic reel systems
- Bubbles-down orientation maintains proper position when rolled
- Recommend: Roller at deep end for easier handling
Pro Tip: If you don’t have a roller yet, invest in one. The £100-300 cost is worth it—you’ll actually use your cover daily rather than leaving it off due to handling hassle. Daily coverage maximises your savings.
“Can I leave it on while the pump is running?”
Absolutely—in fact, this is recommended:
- Cover doesn’t interfere with water circulation
- Pump can run normally underneath
- Heating while covered = maximum efficiency
- Skimmers and returns function properly
Filtering Strategy:
- Run pump/filter during day with cover on (captures solar gains while cleaning)
- Brief removal for skimming surface debris if needed
- Replace immediately after swimming
Exception: Remove cover temporarily if your pool uses a surface skimmer that might catch the cover edge. Ensure proper anchoring or weighting.
“What about winter—can I use this year-round?”
No, Sol+Guard is designed for active swimming season only (roughly April-October in UK):
Why not for winter:
- Bubble covers aren’t engineered for harsh winter weather
- Snow/ice weight can damage GeoBubble structure
- Freezing temperatures affect material flexibility
- You’re not swimming, so solar heating provides no benefit
Proper Seasonal Approach:
- April-October: Use Sol+Guard daily for heating and maintenance reduction
- October-April: Switch to purpose-built winter cover (mesh or solid safety cover)
- Storage: Clean Sol+Guard, dry thoroughly, roll loosely, store in shed/garage away from sunlight
Winter Cover Alternative: We recommend a dedicated winter cover for debris protection during closed season. Contact us for winter cover options for your 14ft x 28ft pool.
“How long will it actually last?”
Expected lifespan: 6-8+ years with proper care:
Factors extending lifespan:
- ✅ Proper storage during winter (biggest factor)
- ✅ Rolling rather than folding (reduces stress points)
- ✅ Maintaining proper water chemistry (prevents chemical damage)
- ✅ Rinsing debris off before rolling (prevents grinding particles into material)
- ✅ Avoiding dragging across rough pool decking
Factors reducing lifespan:
- ❌ Leaving out in winter (freeze-thaw cycles destroy material)
- ❌ Storing in direct sunlight when not in use
- ❌ Excessive chlorine levels (>5 ppm) degrading material
- ❌ Sharp objects puncturing bubbles
- ❌ Walking on cover (not a safety cover—can cause damage)
GeoBubble Advantage: The patented design eliminates traditional weak points, which is why GeoBubble covers last 25% longer than standard bubble covers of similar thickness.
ROI Over Lifespan: At £328.28 initial cost and £900+ annual savings, even a 4-year lifespan delivers £3,600+ in net savings. At 6+ years, you’re looking at £5,400-6,600 total savings—an exceptional return on investment.
⚠️ Important Considerations & Honest Limitations
This Cover is NOT a Safety Device
Critical Safety Information:
- ❌ Cannot support weight of children, pets, or adults
- ❌ Not a safety cover – does not prevent access to water
- ❌ Not a drowning prevention device
- ✅ If safety is a concern: Install a fence or purchase a certified safety cover instead
Why this matters: Bubble covers are designed for thermal performance, not structural strength. A child or pet stepping onto Sol+Guard will go through it into the water. Never rely on this cover for safety.

Production & Delivery:
- Manufacturing: 2-3 weeks (custom-cut to exact dimensions)
- Not available for immediate dispatch (prevents waste from stock of every size)
- Plan ahead: Order before season starts for on-time delivery
Why made-to-order is actually beneficial:
- Fresh material (hasn’t been sitting in warehouse degrading)
- Precision sizing for your pool dimensions
- Reduced environmental waste
- Lower costs passed to you (no inventory holding costs)
Performance Variables: Individual Results Vary
Your savings will differ based on:
Climate factors:
- ☀️ Sunshine hours (higher in South, lower in North)

- 💨 Wind exposure (windy locations lose more heat)
- ☔ Rainfall (affects solar gain opportunities)
Pool specifics:
- Size (calculations based on 14ft x 28ft)
- Depth (deeper pools hold more heat longer)
- Location (sheltered vs exposed affects retention)
- Surface area to volume ratio (shape matters)
Usage patterns:
- Season length (May-Sept vs April-Oct vs year-round)
- Daily usage (removing cover reduces efficiency)
- Target temperature (higher temps = more heating needed)
- Night coverage (critical for heat retention)
Heating system:
- Heat pump efficiency (COP rating affects baseline costs)
- Gas vs electric vs solar (different fuel costs)
- Existing vs new equipment (older systems less efficient)
The guarantee we CAN make: Whatever your current heating and maintenance costs, Sol+Guard will significantly reduce them. The exact percentage depends on variables above.
📐 Sizing & Installation Guide
Is 14ft x 28ft Right for Your Pool?
This cover size fits pools with water surface dimensions of:
- 14 feet (4.27 metres) wide
- 28 feet (8.53 metres) long
How to measure:
- Measure water surface (not pool exterior)
- Add 6-12 inches overlap on each side (covers typically float 3-6″ onto deck)
- For rectangular pools: Measure straight across at widest/longest points
- For shaped pools: Measure bounding rectangle (maximum length × width)
Available sizes: Sol+Guard comes in multiple dimensions to fit pools from 10ft x 20ft up to 18ft x 36ft. [View all Sol+Guard sizes]
Custom sizing: Need different dimensions? We offer bespoke cuts for shaped pools or non-standard sizes. Contact us with your pool measurements for a custom quote.
Installation Steps
Initial setup (5-10 minutes):
- Orientation check: Bubbles face DOWN toward water (smooth side up)
- Positioning: Unfold cover alongside pool at shallow end
- Deployment: Pull cover across water surface (it will float)
- Adjustment: Center cover with even overlap on all sides
- Roller attachment (if using): Secure leading edge to roller tube with straps or clips
Daily use (1-2 minutes):
- Morning: Roll or fold cover off pool before swimming
- Evening: Replace cover immediately after last swim of day
- Overnight: Critical period—cover must be on to retain heat and prevent evaporation
Pro tips:
- Two people make handling easier initially (but one person can manage solo after practice)
- Slight breeze actually helps deployment (lifts cover as you unroll)
- Trim cover if it extends too far onto decking (ensure it remains adequate size)
💡 Maximising Your Savings: Best Practices
The Daily Discipline That Multiplies Returns
Your savings are directly proportional to coverage time. A cover sitting on the deck saves nothing.
Target: 85%+ coverage time during season
The math:
- 100% coverage (24/7 except when swimming): Maximum £900+ savings
- 85% coverage (on every night, most days): £765+ savings
- 70% coverage (inconsistent use): £630 savings
- 50% coverage (frequently forgotten): £450 savings
How to achieve 85%+:
- Make removal/replacement easy (invest in roller)
- Develop routine (cover goes on = pool use ends for day)
- Prioritise overnight coverage (when most heat loss occurs)
- Cover during rainy days (prevents debris, maintains temp)
Combining with Other Pool Heating Strategies
For maximum efficiency, use Sol+Guard with:
1. Heat pump (most common combination):
- Sol+Guard preheats water daily through solar gains
- Heat pump tops up to desired temperature as needed
- Result: 70% reduction in heat pump runtime
- Combined savings: £600-850/year on heat pump operation
2. Solar panels (ultimate eco-friendly setup):
- Solar panels heat water during day
- Sol+Guard retains heat overnight + adds direct solar gains
- Result: Minimal conventional energy use
- Combined savings: Up to 90% reduction in auxiliary heating needs
3. Gas/oil heater (rapid heating):
- Use heater for quick temperature boosts
- Sol+Guard maintains temperature between heating sessions
- Result: Dramatically reduced fuel consumption
- Combined savings: £400-600/year in gas/oil costs
The synergy principle: Each system compensates for the other’s limitations, creating a more efficient total heating strategy.

🔬 The Science Behind the Savings: Why This Works
Understanding Pool Heat Loss
Your pool loses heat through three primary mechanisms:
1. Evaporation (70% of total loss):
- Water molecules carry latent heat as they evaporate
- Rate: Approximately 88L/day for exposed 14ft x 28ft pool
- Energy equivalent: Each litre of evaporated water removes 2.26 MJ of heat
- Annual impact: Approximately 7,250 MJ = 2,014 kWh of wasted heat energy
- Sol+Guard impact: Eliminates 98% of this loss (saves ≈1,974 kWh)
2. Radiation (25% of loss):
- Heat radiates from warm water surface to cooler air/sky
- Worst at night: Temperature differential between water and air maximises radiation
- Physics: Follows Stefan-Boltzmann law (radiative heat transfer)
- Sol+Guard impact: Air layer in bubbles acts as thermal barrier, reflecting infrared radiation back toward water
3. Conduction (5% of loss):
- Direct heat transfer from warm water to cooler surroundings
- Minimal impact compared to evaporation and radiation
- Sol+Guard impact: Reduces air movement at water surface, minimising convective losses
How GeoBubble Amplifies Solar Gain
Traditional flat covers vs GeoBubble bubble design:
Flat covers:
- Solar radiation passes through material directly to water
- No amplification effect
- Heat transfer depends solely on material conductivity
GeoBubble design:
- Step 1: UV rays penetrate clear top layer
- Step 2: Rays enter air pockets within bubbles
- Step 3: Trapped air heats up rapidly (air is excellent solar absorber)
- Step 4: Heated air contacts water surface continuously across thousands of bubble contact points
- Step 5: Heat conducts efficiently from hot air through thin bubble material into water
- Result: Greenhouse effect multiplies direct solar heating
The greenhouse parallel: Sol+Guard works like a greenhouse—transparent cover lets light in, trapped air layer heats up, warmth transfers to the “growing medium” (your pool water).
University-Backed Performance Data
Testing methodology (UK universities):
- Controlled comparison: Identical pools, one covered with Sol+Guard, one uncovered
- Variables measured: Temperature change, evaporation rate, energy consumption, chemical depletion
- Duration: Multiple season-long studies
- Conditions: Real-world UK weather (not laboratory)
Key findings:
- ✅ Solar gain: Up to 8°C temperature increase on optimal days (June/July, full sun, calm conditions)
- ✅ Evaporation: 98%+ reduction in water loss
- ✅ Energy: Over 50% heating cost reduction (conservative figure—real-world often exceeds 70%)
- ✅ Chemicals: 30% reduction in sanitiser consumption
- ✅ Lifespan: GeoBubble lasts 25% longer than equivalent standard bubble covers
Why this matters: These aren’t marketing claims—they’re peer-reviewed research results from independent UK institutions testing products in British climate conditions.
📋 Comprehensive Disclaimers & Assumptions

Chemical costs:
- Standard chlorine tablets: £9-15/kg
- Uncovered pool: 17kg chlorine/season
- Covered pool: 11.9kg chlorine/season (30% reduction)
Variables Affecting Individual Results
Your actual savings may be higher or lower based on:
Geographic factors:
- ☀️ Scotland/Northern England: Lower solar gain contribution (but similar heat retention savings)
- 🌤️ South/Southwest England: Higher solar gain potential (approaching upper estimates)
- 🌊 Coastal locations: Higher wind = greater uncovered heat loss = larger savings potential
- 🏔️ Elevated sites: Cooler ambient temperature = more heating required = greater savings
Pool-specific variables:
- Larger pools: Greater absolute savings but similar percentage reduction
- Smaller pools: Lower absolute savings but faster ROI due to lower cover cost
- Deeper pools: Better heat retention, slightly lower solar gain penetration
- Shallower pools: Faster solar heating but higher heat loss without cover
- Sheltered vs exposed: Trees/walls reducing wind improve retention in both cases
Heating system variations:
- High-efficiency heat pumps (COP >5.5): Lower baseline costs = smaller absolute savings but excellent percentage reduction
- Older heat pumps (COP 3.0-3.5): Higher baseline costs = larger absolute savings
- Gas boilers: Different fuel cost structure (calculate using £0.07/kWh instead)
- Solar thermal panels: Sol+Guard complements solar heating; combined efficiency >90%
- Electric resistance heaters: Highest baseline costs = largest absolute savings potential
Usage pattern impacts:
- Weekend-only use: Lower baseline costs but cover still provides 70% reduction
- Daily swimmers: More cover removal but night coverage = 60-70% of maximum savings
- Extended season (April-October): Higher absolute savings over longer period
- Heated year-round: Inappropriate for Sol+Guard (winter cover needed)
Performance Expectations: What’s Realistic
Solar heating gains:
- “Up to 8°C” occurs in optimal conditions: Clear sky, full sun, June/July, calm, cool ambient temperature
- Typical daily gains: 2-5°C (still very significant for comfort and energy reduction)
- Cloudy UK days: 0-1°C gain, but excellent heat retention prevents loss
- Sequential effect: Gains compound day-to-day (3°C + 4°C + 2°C over three days = 9°C cumulative)
Heat retention:
- Overnight cooling: Uncovered pool loses 2-4°C; Sol+Guard limits loss to 0.5-1°C
- Cloudy/rainy days: Maintains temperature instead of dropping 1-2°C
- Wind impact: Uncovered pools drop rapidly in wind; Sol+Guard mostly eliminates wind chill effect
Evaporation reduction:
- 98%+ claim: Based on laboratory conditions (100% coverage, no gaps)
- Real-world: 90-95% reduction accounting for brief daily removal and imperfect fit
- Still exceptional: Difference between 95% and 98% = ~1,000L vs 600L loss (both massive improvements)
Lifespan & Durability Expectations
GeoBubble 6+ year lifespan depends on:
✅ Factors extending life:
- Proper winter storage (single biggest factor)
- Daily rolling rather than folding (reduces creasing stress)
- Maintaining water chemistry within normal ranges (FC 1-3 ppm, pH 7.2-7.6)
- Keeping cover clean (prevents abrasive debris grinding into material)
- Using cover roller (avoids dragging across deck)
❌ Factors shortening life:
- Leaving cover exposed during winter (freeze-thaw cycles crack material)
- Excessive chlorine (sustained >5 ppm damages polymer structure)
- Physical damage (punctures, tears, stretching)
- Prolonged UV exposure when not in use (store in shade)
- Folding same creases repeatedly (creates failure lines)
Realistic expectations:
- Excellent care: 7-8+ years
- Good care: 6-7 years
- Average care: 5-6 years
- Poor care: 3-4 years
Even at minimum lifespan (4 years), ROI is exceptional: £328 investment ÷ 4 years = £82/year cost vs £900+/year savings = 1,000%+ return.

Regulatory & Safety Disclaimers
This product:
- ❌ Is NOT a safety cover and cannot support weight
- ❌ Does NOT prevent drowning or provide any safety function
- ❌ Does NOT meet safety cover standards (BSI, ASTM, or equivalent)
- ✅ Is designed for thermal performance and debris reduction only
If children or pets access your pool area:
- Install physical barriers (fence with self-closing gate)
- Consider certified safety cover instead of or in addition to Sol+Guard
- Never rely on bubble cover for safety under any circumstances
- Supervise children near pools regardless of cover type
Pool chemistry responsibilities:
- Maintain proper sanitiser levels despite cover (cover reduces needs but doesn’t eliminate them)
- Test water regularly (2-3 times per week minimum)
- Brush and vacuum per normal schedule (cover reduces debris but doesn’t eliminate maintenance)
- Monitor for algae (proper chemistry prevents this; cover colour is not primary factor)
