🏊 Blue 400M GeoBubble Solar Cover – 14ft x 28ft: Save £600+ Per Year on Pool Running Costs
Why UK Pool Owners Choose This Budget-Friendly Heat Retention Solution
Your pool is costing you more than it should. Every day without a solar cover, you’re losing heat, water, and money. This 14ft x 28ft Blue 400M GeoBubble solar cover could save you £600-800 annually through reduced heating costs, water savings, and chemical consumption – paying for itself in just one swimming season.*
💰 The Real Cost of Running Your Pool Uncovered
Before investing in a solar cover, most pool owners face these hidden expenses:
- £700-900/year in additional heating costs as warmth escapes overnight
- 32,000 litres of water lost to evaporation (equivalent to 400 baths)
- 5kg+ of extra chlorine needed as chemicals evaporate
- Hours of cleaning time removing debris, leaves, and insects
- Shorter swimming season due to inconsistent water temperatures
What if you could eliminate most of these costs with one simple solution?
🔥 How This Cover Transforms Your Pool Economics
The Blue 400M GeoBubble solar cover works as an invisible barrier between your pool and the elements, delivering three critical functions:
1. Heat Retention That Cuts Energy Bills by Up to 70%*
The 400-micron thick bubble structure creates thousands of insulating air pockets that trap warmth in your pool water. When combined with your existing heat pump, this cover can reduce electricity consumption by up to 7,000 kWh per year – that’s £700-900 in savings at current UK energy rates.*
Before vs. After Comparison:
| Without Solar Cover | With Blue 400M GeoBubble |
|---|---|
| £900/year heating costs | £270-450/year heating costs |
| Heat loss overnight: 3-5°C | Heat loss overnight: 0.5-1.5°C |
| 8-10 hour reheat time daily | 2-3 hour reheat time daily |
| Swimming season: May-August | Swimming season: April-September |
2. Evaporation Control That Saves 32,000 Litres Annually
Evaporation is the silent thief of pool maintenance. Every day, your uncovered pool loses water, heat, and dissolved chemicals. This cover reduces evaporation by up to 98%, keeping water where it belongs – in your pool, not in the air.*
The Water Savings Breakdown:
- Average evaporation without cover: 4-6mm per day (summer)
- With Blue 400M cover: 0.1-0.2mm per day
- Annual water saved: 32,000 litres for a 4m x 8m pool
- That’s 400 baths worth of water you won’t need to replace
- Water savings value: £80-120/year (based on metered water rates)
3. Chemical Protection That Reduces Chlorine Use by 30%*
When water evaporates, your carefully balanced chemicals go with it. The Blue 400M GeoBubble cover acts as a protective shield, maintaining chemical levels and reducing the need for constant rebalancing.
Chemical Savings You’ll Notice:
- 5kg less chlorine needed per swimming season
- 30% reduction in overall chemical consumption
- Fewer pH adjustments required (water chemistry stays more stable)
- Less time testing and treating your pool
- Annual chemical savings: £100-150*
Your Total Annual Savings: £600-800+*
| Savings Category | Annual Benefit |
|---|---|
| Energy/heating costs | £450-630 |
| Water replacement | £80-120 |
| Chemical consumption | £70-100 |
| Reduced cleaning time | Priceless |
| TOTAL ESTIMATED SAVINGS | £600-850/year |
ROI Timeline: 4-8 months (typical cover cost vs. annual savings)*
🌟 Why the Blue 400M GeoBubble Design Outperforms Standard Covers
GeoBubble Technology: 25% Longer Lifespan
Unlike traditional bubble covers that deteriorate quickly, the patented GeoBubble design features interconnected bubble cells that resist the three main causes of cover failure:
- UV degradation (protected by the blue tint)
- Chemical attack (thicker material resists chlorine exposure)
- Physical stress (rounded bubble design distributes tension evenly)
What This Means for You:
- 4-year manufacturer warranty (vs. 1-2 years for standard covers)
- Expected lifespan: 5-7 years with proper care
- Lower cost per year of ownership
- Fewer replacement purchases
400-Micron Thickness: The Budget Sweet Spot
The 400M thickness is specifically designed for UK pool owners who want excellent heat retention without premium pricing:
| Cover Thickness | Best For | Heat Retention | Price Point |
|---|---|---|---|
| 400M (This Cover) | Budget-conscious owners, above-ground pools | 70-75% | Entry-level |
| 500M | Balanced performance | 75-80% | Mid-range |
| 600M | Maximum heat retention | 80-85% | Premium |
Why 400M Works for Most UK Pools:
- Sufficient insulation for April-September swimming season
- Lightweight enough for easy manual handling
- Compatible with standard pool rollers
- Best value-for-money for recreational pool use

Blue Tint Benefits
The translucent blue material provides:
- UV ray transmission for modest solar heating gains (up to 8°C temperature increase possible)*
- UV protection that extends cover lifespan
- Aesthetic appeal that looks natural on pool water
- Light filtration that reduces (but doesn’t eliminate) algae growth
📏 Perfect Fit for Your 14ft x 28ft Pool
This cover is precisely sized for pools measuring 14 feet by 28 feet (approximately 4.3m x 8.5m), making it ideal for:
- Medium to large rectangular in-ground pools
- Above-ground oval pools in this size range
- Lap pools of standard dimensions
Installation Made Simple
Bubbles Face Down: Position the cover with bubble side facing the water for optimal heat transfer from trapped air pockets directly into your pool.
Trimming Options: The cover can be trimmed slightly to fit pools with minor dimensional variations (within 10cm/4 inches).
Roller Compatibility: The 400M thickness is lightweight and works perfectly with manual pool roller systems for easy deployment and removal.
Pro Tip: Consider adding a reel system if not already installed – it transforms cover management from a 10-minute job to a 30-second task.

🔒 Filter Protection Less debris means your filtration system works more efficiently and requires less frequent backwashing or cartridge cleaning.
🌍 Environmental Impact Reduce your carbon footprint by cutting heating energy consumption by up to 7,000 kWh annually – equivalent to removing a small car from the road for a year.
⚠️ Important Considerations: What This Cover Is NOT
To ensure complete transparency, here’s what you need to know:
Not a Safety Cover
This solar cover is designed for heat retention and debris protection – it cannot support the weight of children, adults, or pets. If someone or an animal steps onto the cover, they will fall through into the water.
Safety Recommendations:
- Install perimeter fencing if young children or pets have pool access
- Always supervise when the pool area is accessible
- Consider a dedicated safety cover for winter months or extended non-use periods
- Never leave the cover partially deployed where it could create entrapment risk
Not a Winter Cover
The Blue 400M is optimized for the April-September swimming season in the UK. When closing your pool for winter:
- Remove and store the solar cover in a cool, dry location
- Install a purpose-built winter cover designed for harsh weather
- Clean and dry the solar cover before storage to maximize lifespan
Not a Substitute for Pool Heating
While this cover provides modest solar gains (up to 8°C increase in optimal conditions)*, it should be used in combination with a heat pump or solar heating system, not as a replacement. The cover’s primary function is heat retention, not heat generation.
Best Practice: Heat your pool to desired temperature → Apply cover overnight and when not in use → Maintain temperature with 70% less energy
🤔 Frequently Asked Questions
How much can this cover really save me?
Based on typical UK pool usage (4m x 8m pool, 6-month season, heat pump heating), expect £600-800 in annual savings through reduced heating costs (£450-630), water replacement (£80-120), and chemical consumption (£70-100).* Individual results vary based on pool size, local climate, energy rates, and usage patterns.
Will this heat my pool on its own?
The blue tint allows UV transmission, which can raise water temperature by up to 8°C in optimal conditions (full summer sun, extended coverage time).* However, this should be viewed as a bonus – the cover’s primary value is retaining heat generated by your heating system, not replacing it. Think of it as insulation, not a heater.
How long will this cover last?
With proper care, expect 5-7 years of reliable performance. The 4-year warranty covers manufacturing defects, but the GeoBubble technology typically extends usable life well beyond the warranty period. Key longevity factors:
- Store properly during winter (clean, dry, out of direct sunlight)
- Remove sharp debris before it punctures material
- Use with a roller system to minimize handling stress
- Balance pool chemistry to avoid chemical damage
Is 400M thick enough for UK weather?
Yes, for most recreational pools. The 400M thickness provides 70-75% heat retention, which is sufficient for the UK swimming season (April-September).* It’s the most popular choice for budget-conscious pool owners and above-ground pools. Consider upgrading to 500M or 600M only if:
- You have a very exposed or windy location
- You want to extend your season into March/October
- Maximum heat retention is your top priority regardless of cost
Can I use my pool pump with the cover on?
Yes, absolutely. A properly secured solar cover won’t affect pump circulation. The water moves underneath while the cover floats on the surface. Many pool owners leave covers on during daytime filtration cycles to maintain heat.
How do I install and remove it daily?
Manual Method: Two people can remove or deploy the cover in 5-10 minutes by carefully pulling/folding from one end of the pool.
Roller System (Recommended): A pool roller allows one person to deploy or remove the cover in 30-60 seconds. The 400M thickness is lightweight enough for manual rollers, making daily use effortless.
Will this stop algae growth?
The blue tint reduces (but doesn’t eliminate) algae growth by filtering some light. However, it’s not an algae prevention solution like the 500M Energy Guard (opaque black coating). You’ll still need to maintain proper chemical balance. The cover helps by:
- Keeping debris out (less organic matter for algae)
- Reducing chemical evaporation (more stable chlorine levels)
- Blocking some sunlight (slower algae reproduction)
What if it doesn’t fit perfectly?
This cover is sized for 14ft x 28ft pools with minor tolerance for variation. If your pool is slightly smaller, you can trim the edges (cut between bubble rows, not through them). If your pool is larger or a non-standard shape, Parts4Tubs offers bespoke made-to-measure covers – use their solar cover calculator tool for custom sizing.
Do I need to do anything special to maintain it?
Minimal maintenance required:
- Weekly: Remove any debris that accumulates on top
- Monthly: Rinse with clean water to remove chemical residue
- End of season: Clean thoroughly, dry completely, roll loosely, store in a cool, dry place away from direct sunlight
- Avoid: Dragging across rough surfaces, exposing to sharp objects, storing while wet
How does it compare to more expensive covers?
The Blue 400M is the entry-level GeoBubble option, offering excellent value for recreational pool owners. Here’s how it compares:
vs. 500M covers: 500M provides 5-10% better heat retention and slightly longer lifespan, but costs £50-100 more. Choose 500M if you swim frequently or in shoulder seasons.
vs. 600M covers: 600M is the premium option with maximum heat retention and durability, but costs £150-250 more. Choose 600M if extending your season into March/October is worth the extra investment.
vs. Standard (non-GeoBubble) covers: Traditional bubble covers cost £50-100 less but typically fail in 2-3 years. The GeoBubble design pays for itself through longer lifespan and better performance.
