Buying the Best Solar Cover for Your Spa

When buying a solar cover for your spa, it’s essential to consider your needs and expectations. What is your main goal for purchasing a solar cover? Are you trying to warm your water temperature, or would you somewhat lower your heating bill?

Fortunately, using a solar cover gives you the best of both worlds. They have many excellent features that go a long way in letting you get the most out of your Jacuzzi. In the following sections, we’ll take a closer look at the ins and outs of solar spa covers.

We’ll also discuss the many ways that they can benefit you as a hot tub owner. But you must buy the right cover for your spa. Depending on where your hot tub is located makes all the difference in the cover you will need to invest in.

You also want to make sure that it is installed correctly if you’re going to get the most out of your new solar cover. We’ll talk more about that in a moment to ensure that you follow the proper guidelines for installation.

The color of your solar cover also comes into play. A darker cover works to retain heat better than that of a lighter or clear solar cover. If you wish for your hot tub to stay warmer longer, a blue solar cover should yield the best results.

Which Side Is Up on a Solar Pool Cover?

This is important in getting the best results from your new solar blanket. Always make sure that the bubble side goes face down into the hot tub water. Why is this important?

The bubbles are what harness the heat from the sun. When placed directly down into the hot tub, these bubbles transfer the heat into your water. The function is identical to that of a solar pool cover. Pool owners use solar pool covers to heat their pool quickly and efficiently.

And just like when using a pool variant, the bubbles always go into the water. Many pool owners have significantly benefited from using the solar pool and spa covers.

So always make sure that the bare side is up, and the bubble side is down. From here, you can simply trim the cover to the size you need if it is too large.

Some covers will fit perfectly, and you won’t have to worry about this step. But if you need to trim your new cover, they are fortunately effortless to work with. Solar blankets are made of a thin plastic that is easy to cut to the size you require.

Can You Heat a Hot Tub with Solar Panels?

Using solar panels to warm up your hot tub is certainly an option. But it’s important to remember that the cost and effectiveness aren’t quite as reasonable as you’d find with a solar hot tub cover.

Investing in a tub cover is a great way to save money and get fast results. A solar hot tub cover works by using sunlight much the same as solar panels. However, the wait time for your hot tub to warm up is far greater than that of a tub cover.

If you’re looking to enjoy your hot tub as much as possible, you’d be better off going with a solar tub cover. It will heat your water faster, and it won’t cost quite as much, either.

Do Solar Spa Covers Work?

They sure do. Solar spa covers work exactly the same way as solar pool covers. Heat is harnessed from the sun and then transferred into your hot tub water. And thanks to their ability to retain heat, you don’t have to worry about your hot tub getting cold overnight.

These tub covers are also a great way to reduce evaporation. You won’t have to add water to your hot tub as often as you used to. A solar tub cover serves to cut down on your expenses and maintenance costs associated with the upkeep of your hot tub.

If your hot tub is in direct sunlight, you can opt for a thinner solar hot tub cover and save money. Your hot tub will warm up much faster and allow you to enjoy it more frequently.

What Is a Spa Blanket?

A spa blanket is the same as a spa cover. These solar covers work to heat the water of your hot tub using the natural heating abilities of the sun. It’s an affordable option for doing so that yields excellent results. Pool owners rely on these types of cover quite heavily to reduce their maintenance costs.

Spa blankets, like pool blankets, work to reduce your overall expenses by keeping your hot tub warmer longer. Any heating costs associated with the hot tub will effectively be reduced thanks to the properties of the solar blanket.

Investing in a hot tub cover will give you far greater enjoyment out of your hot tub. It’s the best way to heat your hot tub without breaking the bank.
