Whatever you’re looking for in terms of hot tub covers, you’ve come to the right place. Read on to learn more.

What is a Hot Tub Cover?

At its most basic, a hot tub cover is simply a cover that is designed to keep your hot tub protected. However, there is a lot more to it than that, and there are many different types of hot tub covers you should keep in mind when it comes time to do your shopping. Check out this list to help you understand the three main types of hot tub covers you’ll be looking at when you start searching for the perfect one for your spa.

  • Traditional covers – These are the large, bulky plastic covers you have probably seen before. They are usually very thick and can be folded up and placed to the side of the hot tub when it isn’t in use. Although they’re a little outdated, they’re still a great way to heat your hot tub and to keep debris and dirt out of it when you aren’t using it, too.
  • Thermal blankets – There are very thin sheets of plastic covered in tiny bubbles that help them float on the surface of your spa water. They use the heat from the sun to warm up the water and keep it warm as much as possible. They’re a great option if your hot tub is placed in direct or nearly direct sunlight in your backyard.
  • Solar panels – You can use solar panels to not only heat your spa but also operate the entirety of the spa system if you have strong enough panel wattages available. Install a solar panel system for your hot tub and you’ll be able to use the whole thing completely off the grid, which will help the environment and also save you a lot of money in the long run.

Why Does Your Hot Tub Need a Cover?

You might think you understand a lot about why your hot tub needs a cover, but you could be surprised by just how much these covers can really do. Check out this brief list to help you understand how important it is for you to have a hot tub cover at the ready when you use your spa frequently.

  • Hot tub covers keep your water safe. They keep large debris like twigs and leaves from getting into your spa water, and in turn, from drifting into your filter, pipes, and pump. This can prevent a lot of damage from potential problems such as these.
  • Covers can heat your water without the use of your hot tub’s heater. This cuts back on the number of cycles it runs in a day, which can save you a lot of money on your electric bill.
  • If you use solar panel covers, you can run your whole hot tub with one of these simple covers. If you’re looking for a great way to save a lot of money overall, this is an excellent opportunity for you.
  • Hot tub covers also help prevent children from falling into the hot tub, which can be a safety hazard. For this purpose, it’s best to choose traditional plastic covers, but other types may work as well depending on your situation.

Conclusion

Now that you’ve seen how many different options you have to choose from, it’s time to select the right hot tub cover for you. Do you prefer to go with a full solar panel system, or are you happier using a thermal blanket instead? Is a traditional cover more your speed? Whichever you choose, there are a few tips and tricks you can keep in mind to help use your cover more smoothly.

It’s hard to remember whether to put hot tub solar blanket bubbles up or down. However, the general consensus is to put them down. When they’re down, they can help the blanket float easier and provide more space for heat to move. Do this and you’ll never wonder whether to put spa solar cover bubbles up or down again.

When using solar panels, remember that you’ll need to know a little bit about installing them. While they come with directions, you might still want to call a professional to take care of this if you don’t feel comfortable doing it on your own. Always handle solar panels with care to keep them from breaking.

Keep these tips in mind and you’ll have a smoother operation of your solar heating no matter which option you choose. Happy soaking!
