Hot tubs are a popular form of relaxation and therapy, providing a warm and soothing environment for users to unwind and de-stress. Hot tub owners frequently ask whether the jets should be left on when heating the water. Some believe that keeping the jets on will help the hot tub heat up faster, while others argue that turning the jets off is more efficient.
In this article, we will explore this question and consider the factors that can affect how quickly a hot tub heats up, including the type of hot tub, its insulation, and the efficiency of its heating system. By the end of this article, you will better understand how to optimize your hot tub's heating performance and enjoy your spa experience to the fullest.

How Long Does It Take To Heat A Hot Tub?
The time it takes to heat a hot tub depends on several factors, including the size of the hot tub, its insulation, and the efficiency of its heating system. Generally, a hot tub with a well-insulated cover and energy-efficient heating system can take 8-24 hours to heat up from cold to the desired temperature.
The temperature rise rate can also vary depending on the outside temperature and ambient conditions. For example, if the hot tub is in a cold climate, it may take longer due to heat loss in the surrounding environment.
However, once the hot tub is heated, it should easily maintain its temperature. If you plan on using your hot tub regularly, keeping the water at a constant temperature is best to avoid heating it from cold each time.
Additionally, investing in a high-quality hot tub cover and an energy-efficient heating system can help reduce heating time and save on energy costs in the long run.
Why Does Heating A Hot Tub Take So Long?
Heating a hot tub can take considerable time due to several factors. Firstly, hot tubs are designed to hold a large volume of water, which takes longer to heat up than a smaller volume. The time it takes to heat the water depends on the size of the hot tub, the amount of water it contains, and the desired temperature.
Another factor that can impact heating time is the efficiency of the hot tub's heating system. Older hot tubs or those with lower-quality heating systems may take longer to heat up or cannot maintain the desired temperature as effectively.
Additionally, the location and insulation of the hot tub can play a role in heating time. If the hot tub is in a cold or windy environment, it may lose heat more quickly, making it take longer to heat up.
Finally, the heating time can also depend on the starting water temperature. If the hot tub has been completely drained and refilled with cold water, it will take longer to heat up than if it is only being topped up with warm water.
It's essential to remember that heating a hot tub can be energy-intensive. Using energy-efficient systems and techniques, such as a high-quality hot tub cover, can help reduce heating time and energy costs.
How Does A Hot Tub Heater Work?
A hot tub heater uses an electrical or gas-powered heating element to warm the water in the hot tub. The heating element is typically located within the hot tub's plumbing system and is controlled by a thermostat that maintains the desired water temperature.
In an electric hot tub heater, the heating element consists of a coil of resistance wire enclosed in a metal housing. When the hot tub's control panel is turned on, an electrical current flows through the resistance wire, heating it and transferring the heat to the surrounding water. Electric hot tub heaters are generally less expensive to install and operate than gas heaters but can take longer to heat the water.
On the other hand, gas hot tub heaters use a gas burner to heat the water. The burner is typically fueled by propane or natural gas and heats a heat exchanger that, in turn, heats the water. Gas hot tub heaters are generally more expensive to install and operate than electric heaters, but they can heat the water more quickly and are often more efficient for larger hot tubs.
In electric and gas hot tub heaters, the heating element is controlled by a thermostat that senses the water temperature and turns the heating element on or off to maintain the desired temperature. Hot tub heaters are essential to any hot tub, allowing users to enjoy warm and comfortable water regardless of the outside temperature.
Components of A Hot Tub
A hot tub is an electrical appliance with many parts which include:
Electrical Resistance Heaters
A hot tub gets warm through the use of electrical resistance heaters. Water flows through the tub assembly, which will contact a heating element. The exterior section of the housing consists of an outer sheath and a filler insulator.
Pressure Pumps
Usually, a hot tub features one or more pressure pumps, which direct water to the heater. As previously mentioned, the heater is a component you can find in the cabinet. Then, the heater converts heat from the terminal into heat energy.
However, leaving the coil to heat for long durations without use might cause a “dry fire.” A “dry fire” occurs when the coil overheats because the water fails to absorb the heat as required.
Jets and Nozzles
After the heater process, the water runs through what is referred to as a distribution box. The role of this box is to direct water to different nozzles that lead to the tub. Thus, you experience what is referred to as the “jet effect,” which involves water moving through nozzles at different speeds.
In this case, leaving the jets on is less likely to impact the heating up of water. Various other useful methods can help you enhance the heat-up process of your hot tub.
How To Heat A Hot Tub Faster
Here are some tips on how to heat a hot tub faster:
- Start with warm water - If your hot tub has been partially drained, fill it with warm water from a hose or tap. This will reduce the time it takes to heat the water to the desired temperature.
- Use a high-quality hot tub cover - A good-quality one can help retain heat and prevent heat loss through evaporation. Make sure your hot tub cover fits properly and is in good condition.
- Check the insulation - If your hot tub is not well-insulated, it will take longer to heat up. Make sure the hot tub is properly insulated, and consider adding extra insulation if necessary.
- Use a hot tub heater with a high BTU rating - The higher the BTU rating of your hot tub heater, the faster it will heat the water. Consider upgrading to a more powerful heater if your current heater is not efficient enough.
- Consider using a hot tub thermal blanket - A thermal blanket can help trap heat in the water and prevent heat loss through evaporation.
- Keep the hot tub covered while heating - Keep the hot tub cover on while the hot tub is heating up to prevent heat loss through evaporation and wind exposure.
Conclusion
In conclusion, whether a hot tub heats up faster with the jets on or off is a common topic of debate among hot tub owners. While leaving the jets on may help circulate the water and distribute the heat more evenly, it can also cause heat loss through evaporation and wind exposure.
Ultimately, the most effective way to heat a hot tub will depend on several factors, including the type of hot tub, its insulation, and the efficiency of its heating system. It's important to consider these factors when heating a hot tub to ensure it heats up safely, efficiently, and effectively.
