This all depends on the size of your hot tub, how much it is being used, and what you are heating it with. A mix of water, propane or electric heaters will take 45 minutes to an hour while a solar powered heater might only need 10-12 hours to reach the desired temperature.
It takes about 2 hours to heat up a hot tub. The first time it is heated, the water temperature will be around 95 degrees Fahrenheit. Read more in detail here: how long does it take to heat up a hot tub for the first time.
Hot tubs are particularly appealing since they are spacious, bubbling, and, well, hot. Hot tubs are best appreciated at a comfortable temperature of approximately 100 to 102 degrees Fahrenheit, so you probably don’t invite your friends over with the promise of a chilly or even tepid evening of fun in the backyard spa. But how long should you anticipate your hot tub to heat up to this temperature?
It takes roughly four hours to heat a hot tub to a safe and pleasant temperature of 100 to 102 degrees Fahrenheit; however, it may take anything from three to eight hours. Water warms up at a rate of 5 to 10 degrees Fahrenheit every hour.
Although four hours may seem like a long time to wait to use your hot tub, there are a few things you can do to assist speed up the process. If you possess a hot tub and want to know how to heat it to the perfect temperature in less time, keep reading. Before you know it, you’ll be soaking up the warmth!
Factors Affecting a Hot Tub’s Heating Time
A typical six-person hot tub contains between 320 and 475 gallons of water. That’s a lot of water to heat up when you’re ready to soak in all the warmth and bubbles of your spa. You’ll want it to heat up as rapidly as possible so you can get the most out of your relaxing time.
The time it takes for your hot tub to reach the proper temperature is influenced by a number of variables. Fortunately, you have complete control over all of them, allowing you to choose how long you must wait until the water is exactly perfect.
If you’re just beginning your search for a hot tub to buy, be aware of the electrical differences between 110 and 220 volt hot tubs.
Temperature at the Start
It may seem self-evident, but the length of time it takes to heat up your hot tub is determined by your beginning temperature.
The length of time it takes to heat up your hot tub depends on whether you keep it running all the time. There are good arguments on both sides, and there is no right or wrong answer:
- You may turn off the tub equipment until you wish to use it if you live in a warmer environment or use your spa seldom. That implies you’ll have to heat for longer to attain the proper temperature.
- Leaving your hot tub running all the time can help you achieve 100 to 102 degrees faster, but it will cost you in the long run, particularly in terms of power expenses.
Temperature in the Environment
According to Techopedia, Temperature in the Environment is “a measure of the temperature around a given asset or piece of equipment or other object.” This means that your tub will heat faster if the water inside starts out warmer or if the air around the tub is warmer.
You may claim that you have no influence on the temperature of the air. To some extent, you’d be correct (pun intended). However, by cutting off the wind, you may control the atmosphere surrounding your tub.
Consider any of these ideas to create an effective windshield if your tub is in a windy location:
- Putting up a fence around the property
- Installing a windshield on the tub’s prevailing wind side
- As a natural wind barrier, plant a row or two of plants.
- Using a gazebo or other small structure to enclose the tub
If feasible, place your hot tub in a sunny location to take advantage of the sun’s warmth and maintain a consistent water temperature in your spa.
Cover for a Hot Tub
Heat rises, as we all know. As the temperature of your hot tub water rises, this scientific concept comes into action. Without a cover to keep the heat in, the heated water evaporates into the air, taking a lengthy time to reach the ideal temperature.
It’s critical to have an energy-efficient and well-maintained cover in place when heating up the hot tub to save heating time and keep all that warmth.

Check your cover for cracks, holes, and water saturation on a regular basis. It’s time to replace your old cover with a replacement one if you notice any degradation.
Insulation for Tubs
It’s only natural that a well-insulated hot tub will keep its heat longer. Not only can heat escape into the air from the water’s surface, but it may also escape via the hot tub cabinet’s microscopic crevices and seams.
The base of the hot tub is one place where heat might escape. If you have your hot tub on a concrete pad or another firm surface, you may be shocked at how much this might effect how hot the water in your tub is heated.
Check for these leaky locations and install insulation to stop the seepage to assist reduce the time it takes to heat up your hot tub.
Maintenance on a regular basis
Maintenance isn’t glamorous, and it’s not something that many of us love doing. However, it is a role in how long your hot tub will take to heat up, so it is absolutely a matter to discuss. The time it takes for your hot tub to warm up is also determined by the state of its operating components.
Improve the efficiency of your hot tub and, as a result, the time it takes to heat the water by:
- Filters must be kept clear and clean.
- Filters should be replaced when they can no longer be cleaned.
- Maintaining the pump to ensure optimal efficiency
- ensuring that the jets are in good working order
Jets turned on or off
There is significant controversy about whether operating the jets in a hot tub enhances the pace at which the temperature rises. Some people recommend running the jets while heating the water in the tub so that the warm water flows more easily. Others claim that operating the jets during warm-up causes chilly air bubbles to escape through the water, reducing the heat build-up.
Any influence jets may have on heating time seems to be minor. Running them occasionally during the heating time or turning them on at the end to ensure the warmer water is circulated before anybody enters is an acceptable compromise.
Heater of Superior Quality
A good Heater of Superior Quality equals faster heating time for your hot tub. Every hot tub comes with a heater, but sometimes the original equipment is just a basic, no-frills model that is serviceable, getting the job done efficiently but without pizazz.
The original equipment might begin to operate badly with usage and time. You may also decide that it’s no longer enough and that you’d want to heat your tub with a little more zeal. Thankfully, you don’t need to purchase a new hot tub to get the desired temperature.
Upgrade your hot tub’s heating components or complete heater to a larger, stronger, newer unit to reduce the time it takes to heat your spa by minutes, if not hours.
New and upgraded heaters might be exactly what you need to get into the spa sooner. Improved sensors and controls, as well as more wattage and BTUs per hour, may all help your hot tub operate more effectively and reduce the time it takes to achieve the desired temperature of 100 to 102 degrees.
There are actions you may take as a hot tub owner to influence, if not completely eliminate, the time it takes to heat up your spa. Some projects, such as planting bushes for a windshield, will take some time to complete. Others, like a new heater, provide quicker effects.
Regardless of the aspects of your hot tub issue you choose to fix, the basic reality is that most average-sized hot tubs will take at least three to four hours to achieve the necessary temperature. Implementing a few or all of the above suggestions, on the other hand, may greatly minimize this time.
It takes about 10 minutes for a hot tub to heat up 10 degrees. Reference: how long does it take for a hot tub to heat up 10 degrees.
