💰 Blue 400M GeoBubble Solar Cover – 16ft x 36ft | Save Up to £500+ Per Year on Pool Heating

Stop Wasting Money Heating Your Pool – This Budget-Friendly Cover Pays for Itself in Weeks

🔥 The Problem: Your Pool is Costing You a Fortune

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

• £3-5 per day in wasted heating energy
• 32,000 litres of water lost annually (that’s 400 baths worth!)
• 5kg of chlorine disappearing through evaporation
• Hours spent cleaning debris and rebalancing chemicals
• A pool that’s never quite warm enough when you want to swim

For a 16ft x 36ft pool like yours, these costs add up to £500-900+ annually.*

But here’s the good news: You can eliminate up to 70% of these costs with one simple addition to your pool setup.

✅ The Solution: Blue 400M GeoBubble Solar Cover

The Blue 400M GeoBubble Solar Cover is your budget-friendly gateway to dramatic savings. This isn’t just a piece of plastic – it’s a proven heat retention system that transforms your pool’s efficiency.

What Makes This Cover Special?

🌡️ Reduces Heat Loss by Up to 75%
The 400-micron thick GeoBubble technology traps warm air in thousands of scientifically-designed bubbles, creating an insulating barrier that keeps heat where it belongs – in your water.

💧 Eliminates 90-98% of Water Evaporation
Save 32,000 litres per year (equivalent to 400 baths). That’s not just an environmental win – it’s £80-120 in reduced water bills annually.*

⚡ Cuts Heating Costs by Up to 70%
Your heat pump or pool heater won’t need to work nearly as hard. Expected savings: £350-650 per year depending on your heating system and usage.*

💊 Reduces Chemical Consumption by 30%
Evaporation takes your expensive chemicals with it. This cover saves you approximately 5kg of chlorine annually – that’s £50-80 in chemical costs.*

🛡️ Keeps Debris Out
Leaves, insects, dirt, and bird droppings stay on top of the cover, not in your water. Spend your weekends swimming, not cleaning.

🔬 How It Works: The Science of Savings

Step 1: Trap the Heat

The GeoBubble design features thousands of air-filled pockets that sit on your pool’s surface. When sunlight hits the cover:

1. UV rays penetrate the blue material
2. Heat is transferred into the air bubbles
3. Warm air is trapped against the water surface
4. Heat conducts directly into your pool water

Result: Water temperature can increase by up to 8°C in optimal conditions (sunny UK summer days).*

Step 2: Lock It In

When the sun goes down or on cloudy days, the real magic happens:

• The bubble layer acts as thermal insulation (like double-glazing for your pool)
• Prevents heat from radiating back into the air
• Creates a microclimate that maintains temperature overnight
• Reduces your heater’s workload by up to 70%

Step 3: Stop Evaporation

Evaporation is your pool’s biggest enemy:

• Every litre that evaporates takes 2.4 kJ of heat energy with it
• An uncovered 16ft x 36ft pool loses 87 litres per day in average UK summer conditions
• That’s 32,000 litres per season – enough to fill your pool multiple times!

This cover creates a physical barrier that stops 90-98% of evaporation, keeping water, heat, AND chemicals in your pool.

3. Bubbles face DOWN (this is critical!)
4. Trim to size if needed (scissors work fine)

Time required: 10-15 minutes (one-time setup)

Step 2: Daily Use

Putting cover ON:

• Remove from roller (or fold from pool edge)
• Gently lay over water surface
• Smooth out any air pockets
• Time: 2-3 minutes

Taking cover OFF:

• Pull from one end
• Roll onto storage roller or fold beside pool
• Can leave on while pump runs (no interference!)
• Time: 2-3 minutes

Step 3: Seasonal Storage

End of Season (October):

1. Clean cover with mild detergent and hose
2. Let dry completely (prevents mold)
3. Fold or roll loosely
4. Store in cool, dry place (garage, shed)

Start of Season (April):

1. Unfold and inspect for damage
2. Clean if needed
3. Back on pool – ready to save money!

Maintenance Tips for Maximum Lifespan:

✓ Remove debris regularly (prevents material breakdown)
✓ Don’t drag across rough surfaces (tears the material)
✓ Keep pool chemistry balanced (extreme pH damages covers)

❓ Frequently Asked Questions

Q: Do I still need to run my pool heater with this cover?

A: Yes, for optimal comfort. The cover reduces heating needs by 70%, but won’t raise temperature to comfortable swimming levels on its own. Think of it as making your heater 3-4 times more efficient, not replacing it.

For best results: Use your heater/heat pump to reach desired temperature (28-30°C), then let the cover maintain it. Your heating system will run 70% less, saving you hundreds annually.

---

Q: Can I leave the cover on while the pump is running?

A: Absolutely! The cover doesn’t interfere with water circulation. Just ensure it’s properly positioned and not blocking the skimmer. Many pool owners leave covers on 24/7 during pool season, only removing for swimming.

---

Q: Will this fit my pool exactly?

A: This listing is for 16ft x 36ft (4.9m x 11m). If your pool dimensions differ:

• Slightly larger pool: Trim to fit with scissors (covers can be cut easily)
• Significantly different size: We offer bespoke made-to-order covers in any size
• Use the solar cover calculator on the Parts4Tubs website for perfect sizing

All covers are made to order, ensuring you get the right fit.

---

Q: How is 400M different from 500M or 600M?

A: The “M” stands for microns (thickness):

• 400M (this cover): Thinner = lighter weight, easier handling, budget-friendly, excellent heat retention
• 500M: Mid-weight, slightly better durability, higher solar gain (Sol+Guard) or algae prevention (Energy Guard)
• 600M: Premium thickness, aluminum backing, maximum heat retention, longest lifespan

For most pool owners, 400M provides the best value-to-performance ratio, especially for above-ground pools or first-time buyers.

---

Q: Which side goes up – bubbles or flat?

A: Bubbles face DOWN into the water. The flat side faces up toward the sun. This allows:

• Sun to heat the trapped air in the bubbles
• Heat to transfer directly into the water
• Better contact with water surface for heat conduction

Installing upside-down reduces effectiveness by 30-40%!

---

Q: Does the blue color make a difference?

A: Yes! Color affects performance:

• Clear/Transparent: Maximum solar gain (heats water fastest) but less UV protection for chemicals
• Blue (this cover): Balanced performance – good solar gain + moderate UV protection + aesthetic appeal
• Dark/Opaque: Blocks light (prevents algae) but lower solar heating

Blue is the “goldilocks” option – not too transparent, not too opaque, just right for most UK pools.

---

Q: Can I use this in winter?

A: Not recommended. Solar covers are designed for swimming season (April-October in the UK). For winter:

• Use a purpose-built winter pool cover (mesh design, handles debris and weather)
• Store your solar cover properly (clean, dry, folded)
• Swap back to solar cover in spring

Using a solar cover in winter shortens its lifespan and doesn’t provide adequate winter protection.

---

Q: Is this safe if children or pets walk on it?

A: No. Solar covers are NOT safety covers and cannot support weight. They will sink if walked on, creating a drowning hazard.

Safety measures:

• Use a perimeter fence around the pool
• Supervise children around the pool area
• Remove cover completely before swimming
• Consider a safety cover if this is a primary concern

If safety is your top priority, explore slatted automatic covers or track-mounted safety covers instead.

---

Q: How long does it take to see savings?

A: Immediately! From day one, you’ll notice:

• Week 1: Pool stays warmer overnight, less morning heating needed
• Month 1: First energy bill shows 50-70% reduction in pool heating costs
• Month 3-6: Cover has paid for itself through cumulative savings
• Years 2-5: Pure profit – every penny saved goes straight to your pocket

Most customers report the cover “pays for itself” within one season, then continues saving £500-900 annually for 4-6 years.

---

Q: What if I have an irregular-shaped pool?

A: No problem! Options:

1. Oversized Standard Cover: Order a cover slightly larger than your pool, then trim to fit (works for minor irregularities)
2. Bespoke Made-to-Order: We create custom covers for any shape (L-shaped, kidney-shaped, roman-end, etc.)

Pro Tip: It’s better for a cover to be slightly too large (easy to trim) than too small (can’t add material).

Use the solar cover calculator on Parts4Tubs for accurate measurements, or contact their expert team for sizing advice.

---

Q: Do I need a roller system?

A: Not required, but highly recommended for pools over 3m x 6m. Benefits:

Without Roller:

• Fold cover manually (takes 5-10 minutes)
• Requires 2 people for larger covers
• More wear from folding/unfolding

With Roller (£80-150 investment):

• Roll on/off in 2-3 minutes solo
• Easier daily handling = you’ll actually use it
• Extends cover lifespan (less folding stress)
• Pays for itself through convenience and longevity

For a 16ft x 36ft pool, a roller is a game-changer for daily use.

---

Q: What’s the warranty?

A: This cover includes a 4-year manufacturer’s warranty against defects in materials and workmanship. This is significantly better than standard 2-year warranties on basic bubble covers.

GeoBubble technology lasts 25% longer than traditional designs, and the 4-year warranty reflects this superior durability.

---

Q: Can I return it if it doesn’t fit?

A: Since all covers are made to order specifically for your purchase, returns are typically limited. This makes accurate measurement critical!

To ensure perfect fit:

• Measure your pool carefully (length x width for rectangular pools)
• Use the solar cover calculator on the website
• Contact Parts4Tubs customer service if unsure (they’ll help you get it right)
• Consider ordering slightly oversized if between standard sizes (easy to trim)

Pro tip: Take multiple measurements and use the largest dimensions to avoid ordering too small.

• Lifespan estimates (4-6 years) assume proper care, balanced pool chemistry, and appropriate off-season storage

ROI Calculations:

• Payback periods (3-6 months) are estimates based on median energy savings (£630/year) and typical cover costs (£150-300)
• Your actual ROI will depend on your specific heating costs, pool usage patterns, and cover price
• Savings are compared to running a pool with no cover versus using this cover consistently

These disclaimers ensure transparency. While individual experiences vary, the majority of pool owners using GeoBubble solar covers report substantial savings that meet or exceed these estimates when used consistently throughout the swimming season.

---

🎁 Limited-Time Considerations

Rising Energy Costs:

UK energy prices have increased 60-80% since 2022. Pool heating costs that were £600-800 annually are now £1,000-1,400 for uncovered pools. This cover’s savings are MORE valuable than ever.

Translation: The ROI timeline has actually improved – what used to pay back in 6-8 months now pays back in 3-5 months due to higher baseline costs.

---

Swimming Season Preparation:

Order now for spring/summer readiness:

• All covers are made to order (allow 1-2 weeks production time)
• Peak season (April-May) can see delays
• Early installation maximizes seasonal savings

Best Practice: Order in March-April for optimal season-long benefits.

---

Stock Availability:

Made-to-order items mean no “out of stock” issues, but production capacity is finite during peak season. Ordering early guarantees timely delivery before the first warm swimming days.
