Great Tips On How To Heat Up Hot Tub Fast?


There are many reasons why you would want to heat up your hot tub fast. A couple of reasons would be to have it ready as soon as possible and the other is to reduce your costs.

How long should a hot tub take to heat up?

Hot tubs take at least three to eight hours to heat up or reach suitable temperatures. Factors such as the hose’s water temperature, tub’s water capacity, and other air conditions will affect how long this takes.

The average time for most tubs is around 4 to 8 hours to get to 100 degrees.

Should Jets be on when heating the hot tub?

There are no technical issues known to have been caused by leaving jets open when heating a hot tub. However, many people testify that heating their tub while the jets are closed helps quicken the process.

The theoretical explanation for this is that open jets let in cold air into the tub, delaying the time otherwise taken to heat it; therefore, if one wishes their tub to heat faster than keeping the jets off while at it should be a good idea.

What is the fastest way to heat a hot tub?

On average, water gets hot at a speed of three to six degrees per hour, depending on various environmental conditions. To speed up the heating, you could cover the tub during the process using a quality cover. Ensure that all tub areas are insulated, keep the filters clean, locate its shelter spot, and keep the jets closed.

Another option would be to fill the tub with hot water from the beginning, though this might not be the safest idea. For an excellent solution, incorporate all listed options. Also, make sure that your heater is in great condition since it would be useless to try out any other remedy if the one item supposed to heat the tub is not working rightly.

How long does it take a 110v hot tub to heat up?

The 220v standard spa gets to 104 degrees within eight to 10 hours. This will depend on several climatic conditions and the tub’s size. Therefore, a 110v hot tub will take twice as long since it will heat by one to two degrees per hour. For a 500-gallon tub, this could take up to 24 hours to get to 104 degrees.

Why does my hot tub take so long to heat up?

Temperature circulations are affected by different chemical concepts of an environment. For this reason, heating a hot tub gets affected by factors such as the environment’s pressure and temperature conditions, your heater’s settings, and maybe even the jets’ condition.

To ensure that you are not wasting energy when heating your tub, check that your heater is working accordingly, your tub is well insulated, and no other related components are wearing out or damaged.

Does a hot tub heat up faster with the cover on?

Whether or not your tub will heat faster with a cover depends on how hot the weather is at the time. On a cold or typical warm day, covering a hot tub when heating will keep the incoming heat from escaping into the environment, allowing the process to take less time.

However, if it is already hot outside, you might not need to cover up your tub. In any case, the environment’s heat could help speed up the heating process.

Suppose you will cover the tub when heating, use a quality cover or heavy insulating material. Else, you will only be making matters worse.

How long does it take to heat up a hot tub for the first time?

If you have just bought your hot tub and cannot wait to enjoy it, you might have to wait longer than you expected before it is safe for use. This is because a new tub takes between 8 to 16 hours to heat up. The time will depend on the size of your tub.

You are advised to let the process take its course naturally using the tub’s heater without other speeding mechanics, at least for this first-time process. It will help you know if you bought a perfectly working tub, or you need to contact your buyer for consultation.

How to heat a hot tub without a heater?

While a heater is the most efficient way to heat your tub, sometimes you might need an alternative. Going the solar way could work just right, but this will take some time, depending on how hot the weather is. Y

ou might want to ensure that your landscape does not negatively affect the process by cutting down branches shading the tub. If the floor around your tub is a great heat conductor, the better for you.

How long does it take to heat up a 110v hot tub?

A 110v hot tub is twice as slow as the standard 220v. For this reason, if you have used the 220v tub before, expect a 110v tub to take twice the time.

Since the 220v tub takes at least 10 hours to get to 100 degrees, the 110v will take around 20 hours for the same results.

However, many people opt for 104 degrees for a hot tub, meaning you will need extra time to get the tub to its optimal temperature. This could even take 24 hours if all factors remain constant.

Why is my hot tub not heating up?

If your hot tub is not heating up, then the three prevalent reasons could be causing the problem:

A water circulation problem.

This is shown by an LF or LFO sign on the heater’s topside. When the water passing through your heater is not enough, the heater will not work as it ought to, making it hard for the dispensed water to have the desired temperature.

The heating element is faulty.

You will need an electrician to check if the element of your tub’s heater is working accordingly. If it is not, then you’ll need to fix or replace it.      

The tub’s control board is not working accordingly.

If neither the water circulation not the heater’s element is faulty, then the issue could be with the control board. This is the system that regulates how the heater and pumps operate, so if it is faulty, you might not be able to heat the tub efficiently.

I'm Adnan Sabanovic, the guy behind Hot Tubs Report. I've had a chance to enjoy hot tubs last few years and have really become interested in owning one of them. Nearly every weekend you'll find me spending time with my family or playing sports. If I am not doing that then I'm here writing about tubs on Hot Tubs Report. This blog is a research for my first hot tub which I decided to document and share publically so others can benefit from it as well.
