Do I Need a Pool Cover? Unpacking the Benefits

A sparkling backyard pool is a classic part of the Western Australian lifestyle, offering a cool escape during our long, sun-drenched summers. But with ongoing costs for water, energy, and maintenance, many pool owners are asking themselves: do I need a pool cover?

While it might seem like just another accessory, a quality pool cover is one of the smartest investments you can make for your pool. It’s not just a simple sheet of plastic; it's a game-changer that saves you time, money, and effort. From reducing your water bills to keeping your pool healthier and safer, the benefits are undeniable.

So, if you’re wondering whether a pool cover is worth it, the answer is a resounding yes. Let’s dive into why.

Slash Evaporation and Save Precious Water

Here in Western Australia, water is a precious resource, and evaporation is a pool’s worst enemy. On a hot summer day, an uncovered pool can lose a surprising amount of water—sometimes up to several centimetres a week. This isn’t just bad for our water reserves; it also means you’re constantly topping up your pool, directly impacting your water bill.

A well-fitted pool cover is the single most effective tool for preventing this, acting as a physical barrier that reduces evaporation by up to 97%. This means:

• Lower Water Bills: You’ll spend significantly less on refilling your pool throughout the year.

• Water Conservation: You’re doing your part to conserve water in a state where it matters most.

• Less Chemical Dilution: A more stable chemical balance is another key benefit, as adding less fresh water means you spend less on sanitisers and balancing agents.

Over a year, the water savings alone can be substantial, making a pool cover an investment that quickly pays for itself.

Lock in Heat and Cut Down Energy Costs

There’s nothing worse than wanting to go for a dip, only to find the water is a few degrees too cold. If you're looking for ways to extend your swimming season, you might ask, ‘do I need a pool cover?’ Whether you have a heated pool or rely on solar warmth, a cover is the key to trapping that heat.

Most of a pool's heat escapes into the atmosphere, especially overnight when the air temperature drops. A thermal or solar cover works like a blanket, trapping the heat and keeping your water warmer for longer.

1. For Unheated Pools: A solar cover can increase the water temperature by as much as 8°C. This naturally extends your swimming season, allowing you to enjoy your pool from early spring through to late autumn without needing an expensive heating system.

2. For Heated Pools: If you run a gas or electric heater, a cover is a no-brainer. It can cut your heating costs by 50–70% by preventing heat from escaping. Your heater won’t have to work as hard, reducing its runtime and saving you a small fortune on your energy bills.

By keeping the warmth in, you can swim more and spend less. It’s that simple.

Use Fewer Chemicals for a Healthier Pool

The sun’s UV rays are harsh, and they don’t just cause sunburn—they also break down the chlorine that keeps your pool water clean and sanitised. Leaving your pool uncovered allows the sun to consume chlorine much faster, meaning you'll constantly need to add more to keep the water safe.

A pool cover shields your water from direct sunlight, protecting the chlorine from degradation. This leads to:

• Reduced Chemical Use: You'll use 35–60% fewer chemicals, saving you money at the pool shop.

• Stable Water Chemistry: With less fluctuation in chlorine levels, it’s easier to maintain a balanced and healthy pool.

• A More Pleasant Swim: Less chlorine means the water is often softer and gentler on your skin and eyes.

By covering your pool, you’re not only saving money but also creating a more enjoyable and safer swimming environment for your family.

Spend Less Time Cleaning, More Time Swimming

Leaves, twigs, dust, and pesky insects always seem to find their way into the pool, especially on a windy day. It's a constant chore, and if you value your time, the answer to ‘do I need a pool cover?’ is absolutely yes. This is where it becomes one of the best time-saving devices a pool owner can have.

By keeping your pool covered when it’s not in use, you’ll prevent most of this organic matter from ever reaching the water. The benefits are clear:

• Less Skimming and Vacuuming: You’ll spend far less time with a scoop or robotic cleaner.

• Reduced Strain on Your Equipment: Your skimmer basket, pump, and filter won’t have to work as hard, which can extend their lifespan.

• Prevents Algae Growth: Leaves and other organic matter are food for algae. By keeping them out, you reduce the risk of an algae bloom, which can be a costly and time-consuming problem to fix.

With a pool cover, your pool stays cleaner and swim-ready, reducing the time and effort you spend on pool maintenance.

An Added Layer of Safety

While a pool cover is not a substitute for a compliant pool fence, certain types can add an extra layer of safety, particularly for families with young children or pets.

Hardcovers or automated security covers provide a strong and rigid barrier, completely sealing off the pool surface. These covers can often support the weight of a person, preventing accidental falls into the water. If safety is a top priority, investing in a high-quality, durable cover can provide invaluable peace of mind.

It’s important to note that not all covers are safety covers. Bubble covers and leaf nets will not prevent accidents. Always consult with a professional to find a solution that meets Australian Safety Standards.

Understanding the Different Types of Pool Covers

Pool covers come in various materials and designs, each suited to different priorities. Understanding the main types will help you decide which is the best fit for your backyard.

• Solar (Bubble) Covers: The most popular choice for WA pools. These covers feature a layer of air bubbles that capture the sun's heat and transfer it to the water, effectively increasing the temperature while also being the best defence against evaporation. They are a fantastic all-rounder for extending your swimming season.

• Thermal Foam Covers: Designed for maximum heat retention, these thick, insulated covers act like a doona for your pool. They are the ideal choice if you have a pool heater, as they excel at stopping heat from escaping overnight, significantly reducing your heating costs.

• Leaf and Debris Covers: If your main battle is with falling leaves from nearby trees, a mesh leaf cover is a practical solution. These covers stretch across the pool and act as a net, catching debris while allowing rainwater to pass through. They are primarily for cleanliness, not for heating or significant evaporation control.

• Automated Covers: Experience ultimate convenience and safety with automated covers that open and close with just the push of a button. Often made from rigid, interlocking slats, they provide a secure barrier over the pool, adding a significant layer of safety while also excelling at heat retention and evaporation prevention.

Unlock a Cheaper, Cleaner, and Warmer Pool

Considering the significant savings in water, energy, chemicals, and time, it's clear that a pool cover is an essential piece of pool equipment. It makes pool ownership cheaper, easier, and more enjoyable, protecting your investment and giving you more time to do what you love—swim.
