Do you just purchase a hot tub?

And if you did, are you wondering how long it will take to heat the water?

Well, we’re here to tell you that you’re not alone!

Many people have asked this same question.

In this blog post, we’ll answer this question and give you some tips on how to heat your hot tub water more quickly so that you can start enjoying it sooner!

How Long Does It Take To Heat Up Hot Tub Water

When you finally get that long-awaited hot tub, you just want to fill it up with water and jump right in. But you’re probably wondering how long it will take to heat the water.

Unfortunately, there is no one answer to this question as it depends on a few factors.

Assuming that you have a standard-sized hot tub and you are using a good quality heater, it should take between 3 to 6 degrees per hour.

So, if you have a tub that holds 350 gallons of water and you want to heat it from 60 degrees to 90 degrees, it will take between 12.5 hours and 22.5 hours.

Of course, these are just estimates. There are a lot of factors that can affect how quickly your hot tub heats up. But this should give you a general idea.

Factors That Will Affect How Long It Takes To Heat Hot Tub Water

Many factors can affect how long it takes to heat your hot tub water. Here are some of the most common ones:

– The size of the hot tub: The larger the hot tub, the longer it will take to heat the water.

– The temperature of the surrounding air: If it’s a cold day, it will take longer to heat the water than if it’s a warm day.

– The type of heater that is being used: Some heaters are more powerful than others and will heat the water more quickly.

The manufacturer of your hot tub will play a role in this as well. If you buy a cheap hot tub, it likely won’t have a very powerful heater.

As a result, it will take longer to heat the water. Conversely, if you buy a high-end hot tub with a top-of-the-line heater, it will heat the water more quickly.

Some hot tubs have better insulation than others. This means that they will retain heat better and won’t lose heat as quickly to the surrounding air.

As a result, it will take less time to heat the water back up after you’ve used it. In general, higher-end hot tubs have better insulation than lower-end models.

Tips For Heating Your Hot Tub Water Quickly

If you would like to speed up the process of heating your hot tub water, there are a few things you can do.

First, make sure that the hot tub cover is properly in place. A hot tub cover should fit snugly over the top of the tub so that no heat escapes.

If your hot tub doesn’t have a cover, or if the cover is damaged, you can buy a new one. Hot tub covers typically cost between $100 and $200.

You can also try pre-heating the water before you get in. This process involves turning on the hot tub jets and running the heater for a few minutes before your hot tub soak.


This will help to raise the water temperature a few degrees so that it doesn’t have to work as hard to heat the water once you’re in.

Finally, make sure that the area around your hot tub is well-insulated. This will help to keep the heat in and make the heating process more efficient.

If you follow these tips, your hot tub should be ready for you to enjoy in no time!

The Best Time of Day To Heat Up Your Hot Tub

The time of day will also play a huge part in heating your hot tub water.

If you live in an area that experiences a lot of direct sunlight, then the daytime is going to be the best time to heat your water.

The sun will help to raise the water temperature a few degrees, making it easier for your heater to do its job. This is the case in summer when the sun is at its peak.

However, if it’s during winter and you live in a climate that doesn’t get a lot of sunlight, then it’s going to be better to heat your tub at night.

The lack of sunlight will mean that the water will lose heat quicker, so you’ll need to give it more time to heat up. Plus, you can enjoy a nice, warm soak under the stars!

Either way, make sure you give yourself enough time to heat the water before you want to use it.

How To Save Money On Heating Your Hot Water

When it comes to heating hot tub water you will have to use either solar power or rely on the electrical company.

Solar power is the more efficient and environmentally friendly option, but it can be costly to set up.

If you’re looking for ways to save money on heating your tub, then here are a few tips:

– Use a cover: This will help to keep the heat in and stop the water from cooling down too quickly. Make sure the cover fits properly and is sized for your hot tub.

– Use a lower temperature setting: Reducing the temperature by 10 degrees, especially in the summer, when you know you will not be using it for a while can also help conserve energy.

– Place your tub in a sunny spot: If you have the option, placing your hot tub in a spot where it will get direct sunlight will help to keep the water warm. This is especially true in the winter months when the sun isn’t as strong. (This may not always be feasible

– Use less water: If you’re only using the tub for one or two people then you won’t need as much water, which will mean it will take less time to heat up.

– Beef up the insulation in the tub: This will help to keep the heat in and stop the water from cooling down too quickly. Add a layer of insulation or you can buy purpose-made insulation covers or try using bubble wrap.


Now that you know all there is to know about how long it takes to heat hot tub water, it’s time to put this knowledge into practice.

Heating your hot tub quickly and efficiently boils down to understanding a few key factors and following some simple tips.

Keep these in mind next time you want to take a soak in your bubbly bathtub.
