The quickest way to warm up your hot tub is by using more than one method together.
Start by filling it with hot tap water, which will already be much warmer than cold tap water.
Follow this up by using a high-quality heater that comes with a fast heating system.
Additionally, using a solar cover or a hot tub bladder can significantly improve heat retention, speeding up the process further.
Using multiple methods synergistically can dramatically reduce the time you spend waiting for your hot tub to reach your desired temperature.
It’s the practical approach for those who don’t want to keep testing their patience and are looking for quick results.
Use a Solar Cover
A solar cover can absorb heat from the sun and transfer it to your hot tub water.
Even on a moderately sunny day, a solar cover can increase the water temperature by several degrees over a few hours.
Remember, a solar cover is effective but also dependent on weather conditions.
On cloudy or rainy days, the solar cover might not be of much help.
However, it still serves the purpose of reducing heat loss through evaporation, so it’s a win-win.
Pre-Heat the Water
Filling your inflatable hot tub with hot water from the tap can quickly help you get the water to the temperature you want.
Hot tap water is generally around 120°F, which will give you a head start compared to filling it up with cold water.
However, there are some downsides.
Using hot water can be expensive and not very environmentally friendly.
If you opt for this method, it’s crucial to keep an eye on the temperature to avoid exceeding the safety limits of your inflatable hot tub and your own comfort.
Insulate the Base
A lot of heat is lost through the bottom of your inflatable hot tub.
Placing an insulating foam board or a specialized hot tub base can significantly reduce this heat loss.
This helps the water heat up faster and also maintains the temperature for longer periods.
A well-insulated base is not only good for heat retention but also for the longevity of your inflatable hot tub.
It provides extra protection from sharp objects that might be on the ground, offering a double benefit.
Use a Heat Pump
A heat pump can be a game-changer when it comes to heating your inflatable hot tub quickly.
These devices are designed to pull heat from the surrounding air and transfer it to the water in your tub.
Because they can be more efficient than conventional electric heaters, you might find that your hot tub reaches the desired temperature more quickly.
Heat pumps are particularly effective in milder climates where the air temperature is not too low.
Before investing in a heat pump, make sure to check compatibility with your inflatable hot tub model.
Installation may require professional assistance to ensure it integrates well with your existing system.
Bypass the Filter
The filter in your inflatable hot tub is vital for maintaining water quality, but it can slow down the heating process.
If you’re aiming for a quick heat-up, temporarily bypassing the filter system might be an option.
This allows the heater to focus solely on raising the water temperature rather than also pushing water through the filter.
Keep in mind that bypassing the filter should only be a temporary measure and should be done with caution.
Make sure to follow any manufacturer guidelines and to promptly reactivate the filter once the desired temperature is reached.
Bypassing the filter too often or for extended periods can compromise water quality.
Use Heated Stones
Utilizing heated stones can be an age-old but effective way of raising your hot tub’s water temperature.
Stones retain heat well and can transfer this heat to the water when placed inside the tub.
To do this, heat large, chemical-free stones in a fire until they are hot to the touch.
Using heat-resistant gloves or tools, carefully place the stones in the water.
This method is somewhat unconventional and requires careful handling.
It can be a quick way to elevate water temperature, especially if you’re enjoying your inflatable hot tub in an outdoor or rustic setting.
Always ensure that the stones are free from chemicals or substances that could harm the hot tub or its occupants.
Coiled Hose Solar Heater
A coiled hose solar heater is a DIY solution that harnesses the power of the sun to heat your hot tub water.
Take a long, black garden hose and coil it in an area that receives plenty of sunlight.
Connect the hose so that water from your tub will flow through it before returning to the tub.
As the water travels through the sun-heated hose, it picks up heat.
This method is particularly effective during the warmer months and in sunny climates.
While it won’t heat your tub as quickly as an electric heater, it’s an eco-friendly and cost-effective way to give the heating process a boost.
Make sure to use a hose made from materials safe for hot water to avoid any health risks.
Using an energy-efficient timer connected to your hot tub’s heating system allows you to schedule heating during off-peak hours.
Or when the ambient temperature is at its warmest.
This method doesn’t speed up the heating time per se.
It does make the heating process more efficient and potentially quicker due to optimal timing.
An energy-efficient timer can also save you money on electricity bills by running the heater when energy rates are lowest.
Most modern timers allow for easy programming, letting you schedule heating times that best suit your usage patterns and lifestyle.
Make sure to choose a timer compatible with your hot tub’s electrical system.

How to Heat Up Inflatable Hot Tubs Faster By Season
Heating an inflatable hot tub is not a one-size-fits-all endeavor.
The process varies greatly depending on the season.
The atmospheric temperature, wind speed, and even humidity can affect how quickly your hot tub heats up.
If you’ve ever wondered how to adjust your heating strategies based on the time of year, this article is for you.
Below, we will explore practical methods for heating your inflatable hot tub faster, customized for each season.
Spring is a season of renewal, but it’s also a season of fluctuating temperatures.
During the day, it might be warm enough to make you consider using the hot tub, but as the evening approaches, the temperatures often drop.
One way to combat this is by using a solar cover during the daytime when the sun is out.
The cover will trap the sun’s heat and help warm up the water faster.
Additionally, you can utilize windbreaks during the spring season to keep your hot tub area isolated from the cooler winds.
Fences, outdoor screens, or even strategically-placed shrubs can serve as effective windbreaks.
These not only provide a measure of privacy but also help to maintain the water temperature.
In summer, you’ll find that your hot tub heats up more quickly due to the warmer ambient temperature.
However, this season also brings with it the challenges of heat loss through evaporation.
To counteract this, use a hot tub bladder or a lightweight thermal cover when the tub is not in use.
In addition, consider turning off any additional water features like waterfalls or fountains that could lead to faster evaporation.
It might be tempting to keep your hot tub open to the balmy summer air.
But closing it with a good quality cover when not in use will minimize heat loss and speed up the heating process for later use.
Fall brings cooler temperatures and often unpredictable weather.
During this time, you can insulate the base of your inflatable hot tub to minimize heat loss.
Using foam boards or specialized hot tub base tiles can make a significant difference.
Also, consider using a heater with a higher wattage to speed up the heating process.
Always make sure to adhere to manufacturer guidelines and safety procedures when upgrading or changing heaters.
Autumn evenings can be chilly, so pre-heating your hot tub in the afternoon can provide a warm, ready-to-use spa in the evening.
Winter poses the most significant challenge when it comes to heating an inflatable hot tub.
It is highly advisable to use a heavy-duty thermal cover to trap heat.
Some people even add extra layers of insulation around the tub using thermal blankets or specialized hot tub enclosures.
Pre-heating the water can also be an effective method.
Fill the hot tub with hot tap water to give it a head start. Keep in mind that this method may not be cost-effective or environmentally friendly.
Therefore, it’s best to combine this with other insulation methods to ensure that the heat is retained for as long as possible.
How Long Does It Take to Heat Up an Inflatable Hot Tub?
On average, it takes about 12-24 hours to heat an inflatable hot tub to 104°F (40°C), starting from a water temperature of around 60°F (16°C).
However, several factors can affect this timing, including:
- Heater power
- Initial water temperature
- Ambient conditions.
If you’re filling your tub with hot tap water, this duration can be reduced significantly.
The key here is planning.
If you know you’re going to want to take a dip tomorrow, start heating your hot tub today.
If you’re in a real rush, combining several of the fast-heating methods we discuss in this article can bring this time down considerably.
How Do I Turn Up the Heat in My Inflatable Hot Tub?
Turning up the heat is usually done through the control panel provided with your inflatable hot tub.
Many new hot tubs have easy-to-use digital buttons that let you change the water temperature one degree at a time.
Always refer to your owner’s manual for specific instructions on how to adjust the settings on your particular model.
However, remember that cranking up the heat to the maximum setting won’t necessarily heat the water faster.
Most heaters work at a fixed rate.
The best way to speed up the process is to combine it with other methods, like using a solar cover or a hot tub bladder.
Does Turning Jets On Heat Hot Tub Faster?
Turning on the jets does not directly make the water hotter.
However, it does help in circulating the water, which can lead to more even heat distribution.
When the water circulates, it helps the heater work more efficiently, but the speed increase is marginal.
While using the jets can make your overall hot tub experience more enjoyable, it’s not a fast-track way to heat up your tub.
If your primary goal is to warm up the water quickly, focus on methods that directly contribute to raising the temperature.
How Do I Make My Inflatable Hot Tub Hotter than 104?
Raising the temperature of your inflatable hot tub above 104°F is generally not recommended for safety reasons.
Most hot tubs have a maximum heat setting of 104°F to comply with safety regulations.
Heating water above this temperature can put you at risk for hyperthermia and other health problems.
However, if you have a specific reason and have consulted a healthcare professional, some people use external heaters to go beyond the built-in limitations.
Always take the utmost care and closely monitor the water temperature if you choose to go down this route.
Does a Hot Tub Bladder Help Heat Up Hot Tubs Faster?
A hot tub bladder sits between the water surface and the cover, reducing evaporation and heat loss.
By doing so, it helps the water heat up faster and maintains the temperature for a longer time.
It can be an excellent addition for speeding up the heating process.
Hot tub bladders are also useful in reducing chemical evaporation.
Which means you’ll save on maintenance costs in the long run.
They are relatively inexpensive and could be a worthy investment if you’re looking to heat your tub quickly.
