Why a Solar Pool Cover 18Ft is Necessary
From my experience, having an 18ft solar pool cover has been a game-changer for maintaining my pool. First, it helps retain heat incredibly well, which means my pool stays warm longer without constantly running the heater. This not only makes swimming more enjoyable but also saves me a lot on energy bills.
Another reason I find it necessary is the reduction in water evaporation. The cover acts as a barrier, preventing water from evaporating quickly, so I don’t have to refill my pool as often. This is especially important in hot, dry weather when evaporation rates spike.
Lastly, the solar cover keeps debris like leaves and dirt out of the pool, making my cleaning routine much easier. Overall, the 18ft solar pool cover has made pool ownership more convenient, economical, and enjoyable for me.
My Buying Guides on Solar Pool Cover 18Ft
When I decided to get a solar pool cover for my 18-foot pool, I quickly realized there are several important factors to consider. I want to share my experience and tips to help you choose the best solar pool cover that fits your needs.
Understanding What a Solar Pool Cover Does
Before I purchased mine, I learned that a solar pool cover helps retain heat, reduce evaporation, and keep debris out of the pool. It’s like giving your pool a warm blanket that also saves energy and water.
Size and Fit Are Key
Since my pool is 18 feet in diameter, I made sure to get a cover specifically designed for that size. A well-fitting cover maximizes heat retention and prevents water loss. I measured my pool carefully and looked for covers labeled for 18-foot pools to ensure a snug fit.
Material Quality and Thickness
I found that solar covers come in different thicknesses, usually measured in mils. Thicker covers (around 12-16 mil) are more durable and last longer, but thinner ones can be more affordable. I chose a medium thickness that balanced durability and price because I wanted something that would last a few seasons without breaking the bank.
Bubble Design and UV Protection
The bubble side of the cover should face down into the water to trap heat effectively. I checked that the cover had UV inhibitors to protect it from sun damage, which helps extend its life. Some covers also have a blue or clear tint—blue covers tend to absorb and retain more heat.
Ease of Use and Storage
Since I cover and uncover my pool regularly, I looked for a cover that’s lightweight and easy to handle. Some covers come with reels or storage bags, which made my life easier when removing and storing the cover during swimming days.
Price vs. Value
I compared different brands and prices but focused on value rather than just cost. A cheap cover might save money upfront but could tear quickly or lose effectiveness. I invested in a mid-range cover with good reviews to ensure I got a product that lasts and performs well.
Additional Tips from My Experience
- Always clean and dry your cover before storing it to prevent mildew.
- Use a pool cover reel if you have space; it saves time and effort.
- Check the edges of the cover regularly for wear and tear and replace if needed.
- Combine the solar cover with a pool pump timer for even better energy savings.
I hope my guide helps you find the perfect solar pool cover for your 18-foot pool. With the right choice, you’ll enjoy warmer water, less maintenance, and lower energy bills!
