Getting a solar hot tub cover is perfect if you are looking for a good way to protect  your Jacuzzi and a way to get free sun generated heating

Doing this will help reduce your electricity bills.

This is because using a floating solar Jacuzzi spa cover means that you can use solar energy to heat the water in your spa.

Whether you choose a floating spa blanket or opt for a spa cover, you will find everything you need to know in this post.
Purchasing a solar cover can be a very confusing and potentially expensive experience when you don’t know the basics.

So in this article, I will tell you how to choose the correct solar hot tub cover for all your Jacuzzi needs. You will also find information on solar spa panels if you prefer this route instead.

What is a Hot Tub Cover?

A hot tub cover is simply a cover that keeps your tub protected. If it is the type of cover that has air pockets then it will capture energy from the sun and work just like a greenhouse.

They are sometimes called things like “tub covers” or “solar blankets”. A solar cover is environmentally friendly and a sustainable means of maintaining your tub.

This is because it works off renewable solar energy thereby reducing your need to use regular electricity.

The most popular hot tub covers look just like a plastic bubble wrap but don’t judge it by its basic looks.

The cover transfers heat to the water underneath during the day when the sun is out. And then it helps to keep the water warm at night.

In fact, some covers are able to increase the temperature of water by as much as 15 degrees Fahrenheit. This will help reduce the need to heat your tub at the beginning (before you jump in to soak).

Why Does My Hot Tub Need a Cover?

The reasons for getting a hot tub spa cover are a lot more numerous than you might think. Here are some of the reasons why many hot tub owners find them invaluable:

  • Hot tub covers stop things from falling into your tub and potentially damaging it. This is especially necessary if your tub is located outside and exposed to the elements.
  • It also stops large debris, such as twigs and leaves from ending up in the filter, pipes, nozzles or pumps.
  • Using solar panel covers means that you can potentially run the entire system from this power source.
  • Even if you are only able to use the solar cover to run it some times – this will still lead to a reduction in electricity bills.
  • Hot tub covers are good for homes with children or pets. However, if this is your main reason for getting a hot tub cover then you should opt for traditional plastic covers that are very sturdy.

Solar Hot Tub Cover Basics

Micron

Micron is how the thickness of the cover is measured. A “micron” essentially means a very small unit of millimeters. 200 micron is the thinnest lightest hot tub cover while 900 is the thickest and heaviest.

Air pockets

The bubble wrap is not there to make it look nice.

It is what allows your solar cover  to retain heat – just remember to make sure the bubbles always face down.

Color

Choosing the color of your solar cover should not be an aesthetic choice. Different colors have different functions.
Silver/Gold/Blue/Black and other dark colors will help prevent the growth of algae. If you want lots of heat then consider getting silver or gold as they can better reflect the sun’s rays deeper into the water.

Opaque/clear/transparent is ideal for hot climates. This is because a clear cover will be better able to absorb and let in infrared or UVA light which will penetrate into the water thereby keeping it warm.

Electronic Solar Powered Spa Covers

The electronic versions of solar covers do everything the basic bubble wrap covers do but with 100% more intensity and effectiveness.

This is why I will only be reviewing electronic solar hot tub covers from this point onwards.

Which Is The Best Solar Hot Tub Cover?

Solar hot tub covers don’t just keep your hot tub covered so that it doesn’t get damaged by the elements it can be a power source too.

Mr Water Geek Thinking

Covers are completely necessary if your hot tub is outside.

Twigs, stones, debris, leaves, insects and even some animals will find their way into your hot tub if you don’t use a cover. And there is no telling how much damage these things can do once they enter your tub system.

Getting a tub cover is also a good idea if you have young children or pets in the home. However, modern covers are capable of heating your tub water too.

If you’re going to be making this type of investment then it’s worth considering the electronic ones instead of the basic bubble wrap versions. They are more effective and pay for themselves in the long rung with all the money you save on electricity bills.mrwatergeek winner badge

My favorite solar tub cover is the Natural Current NCTHRSPACOV. It is a great product that works very well and offers great value for money.

Happy soaking!
