Your Pool, Your Wallet, and a Smart Solution
South Africa’s glorious climate practically begs for a swimming pool. The long, sun-drenched seasons offer endless opportunities for aquatic enjoyment. However, this luxury comes with ongoing financial commitments. In a country where the cost of utilities, especially water and electricity, is steadily climbing, and where water scarcity is a pressing concern, finding smart ways to manage pool expenses is essential.
Enter the humble pool cover: a simple addition with enormous benefits. This post will guide you through the real-world annual energy savings and cost reductions you can expect from using a pool cover. From reduced water evaporation, lower chemical usage, to more efficient pool heating systems, you’ll see why this smart investment pays for itself.
Decoding Your Current Pool Costs: The Baseline
Before we dive into savings, let’s understand where your money is currently going. Maintaining a swimming pool in South Africa involves three primary recurring expenses:
1. The Price of Water: More Than You Think?
A typical swimming pool holds thousands of liters. A modest 6m x 3m residential pool holds about 27,000 liters, while a large 8m x 4m pool holds around 50,000 liters. Unfortunately, water evaporation constantly drains your pool, especially in summer.
South Africa’s heat and wind cause significant evaporation, and many homeowners must frequently top up their pool, adding to high energy and water bills. With tiered municipal tariffs, the more water you use, the more it costs.
2. Powering the Pump: An Invisible Energy Drain?
Your pool pump is the heart of your pool system, ensuring proper filtration and circulation. But it’s also a silent contributor to your electricity bill. Traditional single-speed pumps are energy-hungry. In contrast, variable-speed pumps and variable-speed pool technology use far less energy, offering big savings over time.
Switching to a variable speed pump can save energy, cut electricity costs, and lower the cost of your pool in the long run. Operating your pool pump efficiently is key to managing your pool’s energy usage.
3. Chemical Costs: Clean, Clear… and Costly
Maintaining clear, safe pool water requires chlorine, algaecides, and balancing agents. This is a regular part of pool care and pool maintenance, and the cost adds up. An uncovered pool means more debris, more cloudy pool water, and more chemicals to correct it.
Snapshot: Average Annual Costs (Uncovered Pools)
| Pool Size | Volume (liters) | Water Cost (R) | Electricity (Pump) (R) | Chemicals (R) | Total (R) |
| Small (6m x 3m) | 27,000 | R4,000–R8,000 | R6,500–R9,500 | R6,000–R10,000 | R16,500–R27,500 |
| Medium (7m x 4m) | 42,000 | R6,000–R12,000 | R7,000–R10,000 | R7,000–R11,000 | R20,000–R33,000 |
| Large (8m x 4m) | 48,000 | R7,000–R14,000 | R7,500–R10,500 | R8,000–R12,000 | R22,500–R36,500 |
The Great Escape: Water Evaporation and How Covers Fight Back
An uncovered swimming pool can lose 35mm–45mm of water weekly in summer. Over a year, that’s around 134,000 liters of water just disappearing!
The Hero: The Pool Cover
A pool cover also acts as a protective shield, reducing water evaporation by 90%–98%. Swimming pool covers, including bubble (solar), solid, and mesh types, help reduce your pool water loss significantly.
At Designer Pool Covers KZN, we offer automatic pool cover options that are easy to use, stylish, and highly effective at cutting evaporation and maintaining a cleaner, warmer swimming pool.
Real Savings Example: Medium Pool
- Water evaporated annually: 134,400 liters
- Water saved with cover (90% reduction): 120,960 liters
- Cost per kiloliter: R25
- Annual water savings: ~R3,024
Chemical Savings: Less Evaporation, Less Expense
Pool chemicals degrade with sun exposure and dilution from water evaporation and rainfall.
A pool cover helps in three powerful ways:
- Blocks sunlight, preserving chlorine
- Prevents debris, reducing chemical demand
- Reduces evaporation, maintaining chemical stability
You could reduce swimming pool chemical use by 35%–60%. That’s about R3,200 saved annually on a typical R8,000 chemical bill.
Heating Bills: Dramatic Energy Savings with a Pool Cover
If you heat your swimming pool, you’re using a lot of energy. Whether through electric heaters, gas, or a solar pool heating system, costs can skyrocket.
The Power of Heat Retention
By covering your pool, you trap warmth, minimize energy loss, and prevent nighttime temperature drops. Evaporation is the biggest culprit in heat loss, and covering your pool keeps that heat in.
- A covered pool heating system can reduce energy consumption by 50%–70%
- Solar pool heating benefits even more, as solar energy is retained longer
- You extend your swimming season naturally
Annual Heating Savings Estimate:
If you’re spending R800/month for 6 months:
- Total: R4,800
- With 60% savings: R2,880 saved annually
Total Annual Savings with a Pool Cover
| Pool Size | Water Savings (R) | Chemical Savings (R) | Heating Savings (R) | Total Savings (Heated) | Total Savings (Unheated) |
| Small | R2,000–R4,000 | R2,400–R4,000 | R500–R1,500 | R4,900–R9,500 | R4,400–R8,000 |
| Medium | R3,000–R6,000 | R2,800–R4,400 | R800–R2,000 | R6,600–R12,400 | R5,800–R10,400 |
| Large | R3,500–R7,000 | R3,200–R4,800 | R1,000–R2,500 | R7,700–R14,300 | R6,700–R11,800 |

Energy-Saving Tips for Running Your Pool More Efficiently
Frequently Asked Questions (FAQs)
1. How much can I save on energy costs by using a pool cover?
A high-quality pool cover can slash your energy costs by reducing the need to heat your pool as often. By trapping warmth and cutting down on evaporation, you’ll conserve both water and energy, making your pool far more cost-efficient all year round.
2. Can I keep my pool warm with solar heating and a cover?
Absolutely! A pool cover works hand-in-hand with solar heating, helping you capture and retain the sun’s energy to heat your pool. This means your system won’t be using more energy than necessary, even if you enjoy a heated pool well into the cooler months.
3. Is a pool cover useful if I run my pump daily?
Yes! Even if you run your pump every day, a pool cover improves your pool’s overall efficiency. It keeps debris out, reduces chemical loss, and helps you run your pool system more effectively, especially if you’re trying to save money with today’s rising energy providers’ costs.
4. Why should I cover my pool for the winter in South Africa?
Covering your pool for the winter helps prevent the loss of thousands of litres of water every year, reduces cleaning time, and protects your local pool from harsh weather. Whether you rely on the sun’s energy or traditional swimming pool heating, a cover ensures everything around your pool stays clean and cost-efficient, which could otherwise cost you around R5,000–R10,000 annually.
Conclusion: A Smart Investment for Every Pool Owner
The verdict is clear: If you own a swimming pool and its equipment in South Africa, you need a pool cover. It can dramatically lower your pool costs, save less energy, and protect the environment.
From reducing evaporation to lowering heating costs, your pool will cost far less to maintain with this single change. The effectiveness of a solar or manual cover lies in using the pool more efficiently and saving resources.
