There’s no way around it: every pool should have a cover.
Some pool owners get by without one, but I can assure you they’re spending way more time and money opening, winterizing and maintaining them than people with covers.
So, yeah: it’s definitely a good idea to invest in a high-quality cover that will last you years to come!
4 reasons why you need a pool cover
There are several reasons why pool covers are a great idea, but among the best is that it will make your life a whole lot easier!
1. For safety
Some swimming pool covers are designed specifically to serve as safety barriers for people or animals who happen to fall in, and are usually made of sturdy mesh and each one has its own weight limits; the higher the weight limit, usually the heavier the cover.
These mesh covers are usually installed with a roller of some type to roll them up either manually or electronically.
2. To save energy
According to Energy.gov, a pool cover is the “single most effective means of reducing pool heating costs.”
About 70% of energy is lost through evaporation and pool covers minimize evaporation. How?
Let’s go back to 6th grade science. Remember when you did those cool experiments that demonstrated how evaporation works? Here’s a refresher:
Evaporation is basically when a liquid substance becomes a gas. And it does this when it is heated. The molecules then move so rapidly that they “escape into the atmosphere as molecules of water vapor.”
How quickly the water evaporates depends on some other factors, too, like wind, temperatures, and humidity but the average pool loses about 25,000 – 50,000 gallons of water per year this way.
That means you’ll have to add more water to keep your pool full, which means your pool heater will have to work harder and longer to heat up the fresh water.
Pool covers also keep heat in the pool and serve to kind of keep your water warming even after you turn the heater off. And solar covers go a step further by collecting the heat of the sun and directing it into the water to warm it naturally.
All these factors help save energy by heating your pool naturally and preventing you from having to add as much new water each week.
3. To reduce chemical use
The most common pool chemical you probably use is chlorine. The problem with chlorine is that it deteriorates under UV rays.
A pool cover will obviously help protect the water from the sun when the pool is not in use, cutting down on the amount of chlorine you need to add each week.
4. To keep it clean
This may be a no-brainer, but keeping your pool covered keeps out unwanted debris. A lot of pool owners don’t think much of this because they simply skim leaves and bugs out of their pools every morning.
But what about the things you can’t see that cling to the bottom and sides of the pool surface like algae spores and dirt?
Keeping a cover on it helps cut back on these unhealthy pool invaders. This also means less scrubbing and vacuuming for you.
Types of inground covers
Now that you understand why a pool cover is so important, let’s go over the different types.
There are basically four types of pool covers:
- Solar covers
- Security covers
- Standard winter covers
- Automatic covers
Let’s check out the pros and cons of each one.
If you’re interested in heating your pool efficiently and cheaply, then a solar pool cover (aka bubble cover) is the way to go.
- Saves you energy and money on your electricity bill
- Minimizes evaporation so you don’t have to constantly re-fill your pool
- Prevents chemical loss because of minimal evaporation
- Prevents algae & debris, keeping your pool cleaner, longer
- Gives you a longer swim season,thanks to that warm water!
- Need to replace it every couple of years
- Not designed to be a safety cover
- Select cover based on your pool size. Actual cover measures approximately 2-ft wider and 2-ft longer.
- Comes complete with all hardware to install on concrete decking
Safety pool covers—sometimes called security covers —are what the majority of pool owners use, and they’re designed specifically to prevent drowning in the event a child or pet wanders into the pool when no one is around.
They’re strongly constructed and usually have some type of anchor system around the edges of the pool to keep it in place and will hold more weight than other covers.
Security covers come in two types: mesh and solid:
Pros: Mesh Covers
- Great at keeping out leaves and other debris
- Able to withstand heavy rainfall
- Doesn’t require a pump to remove the rain, since the rainwater falls through
- Can support a lot of weight, including heavy snowfall
Cons: Mesh Covers
- Since rainwater falls through, pool water can get very dirty
Pros: Solid Covers
- Keeps out all debris, rain, and snow, so pool water should remain clear
- Keeps out UV rays, cutting down on evaporation
Cons: Solid Covers
- Collects moisture, so you need to manually clean it with a pool brush or pool cover pump so it won’t sag or tear
Standard winter covers
- Pool size: 20-feet by 40-feet
- Cover size: 24-feet by 44-feet
Standard winter covers—also called tarp covers—are the most basic types of pool covers and are just what they sound like——tarps made out of polyethylene material.
As the name suggests, many pool owners use these when they’re shutting down their pools for winter season.
- Effectively block UV rays to help fight against evaporation
- Good at keeping out leaves and other debris
- Need to be held down with water bags
- Can only hold very little weight—if too much water gets on top, it will collapse into the pool
Automatic pool covers are usually made out of a vinyl material and tend to be on the expensive side, but some pool owners like them because of their “set it and forget it” features.
- Great at heating your pool due to the heavy vinyl material
- Prevents children and pets from getting into the pool
- Keeps leaves and debris out of the pool
- Expensive to buy, and expensive to replace
- Can sometimes make your pool water too warm during the summer months
Safety precautions & tips
Swimming pool covers are important, but just like anything else involving a pool, there are some precautions you should take to ensure everyone’s safety.
- Never mistake a solar cover or tarp for a safety cover. These covers are not meant to hold much weight and they will fold with very little.
- Take other measures to keep small children out of the pool area if you are using a tarp or solar cover.
- Use a pool cover pump to keep rainfall from weighing down your cover and causing it to sag or tear.
- Never allow children to intentionally walk on a pool cover, even one that is meant for safety. Make every effort to keep your pool area enclosed.
- Check your pool covers often for loose stitching, tearing or wear. Replace them when necessary.
- Read manufacturer instructions carefully as safety covers have specific installation requirements in order to work correctly. Also, some warranties are voided if your pool doesn’t meet certain specifications.
Pool cover accessories you might need
There are lots of extra accessories you may want to consider for your pool cover.
Pool cover pump
- Pool Cover Maintenance - The WAYNE 1/4 HP Reinforced Thermoplastic Pool Cover Pump is a great addition to your pool maintenance. WAYNE model WAPC250 has iSwitch technology, which activates the pump once the water level is at, or above 2 1/8”. Auto Off deactivates the pump when water is at or below 3/4"
- Automatic Pumping - Water level must be at least 2-1/8” for the pump to turn on, prime, and operate. Water levels less than 2-1/8” won’t activate the iSwitch to start the pump, so manual activation will be needed
If you have a pool cover made from a solid material, water from rainfall will collect on top of it, causing it to sag, tear and become too heavy to remove.
A pool cover pump is a device used to pump water the water off the cover to prevent this.
They come in either manual or automatic models that you either turn on when in use or that kick on when they detect water.
Pool cover reel
- Made with durable stainless Steel legs and lightweight aluminum, with a plastic handle and wheels so there's no rust
- Hand crank makes it easy for just one person to smoothly roll up a pool cover, designed with self-fastening attachment points
Reels are used mainly with solar covers.
They are metal gadgets that you install at one end of your pool to roll your cover up with, and usually come with handles so that you can easily roll or unroll the cover.
Pool cover clips
- Cover clips ship in a variety of colors
- Built tough to withstand cold winter temperatures
Pool cover clips are used primarily with above ground pools.
They’re clips that work a lot like clothespins to simply clip the cover in place around the perimeter of the pool.
Pool cover tubes
- Made of full 18-gauge material
- 33% heavier than other water tubes
Pool cover tubes are also sometimes called water tubes or water bags.
They’re made to attach to the edges of the pool cover and hold them in place by being set around the outside of the pool.
They’re heavy when filled with water to stay in place.
Pool cover anchors
A lot of pool covers come with their own anchor hardware.
They’re more reliable than water tubes because they are actually drilled right into the deck; the pool cover ropes are then hooked to the anchor to keep the cover in place.
Most anchors are designed to be pushed down into their settings when not in use.
Best safety covers
