Why Does A Hot Tub Only Go To 104?

A hot tub may be one of the best investments you ever make, especially if you live in a cold climate.

In addition to its obvious physical benefits, it can also help clear up skin conditions such as Eczema and Psoriasis.

If you want to figure out what makes a hot tub great or which one is suitable for your family, check out the Hottubs  and why they go to 104.

Hot tub water and jets give off the heat. The 104°, in this case, is an average of what you would feel right on the tub’s outside, so the heat won’t make it any hotter than that. It then gets regulated at this temperature for safety reasons. A cold tub can only go down to about 100°.

A hot tub will have as many jets as it needs to circulate the hot water and keep it at 104°, but you can use fewer than that.

The reason for this is that the more jets there are, the more water circulates, which increases the load on the pump, this can cause problems.

It surprises many people to discover this, but a large jet will circulate as much water as many small jets clustered together.

If you want a hotter tub, you can cover it and use the sun to warm it up. Theoretically, if the outside air temperature is around 100°F, there’s enough heat in the water to keep it at 104°F.

If there is not too much wind, you can use a towel to cover it. Another trick is to fill it and leave it uncovered until the sun has warmed it up, then cover it.

You can also add heat with a heater, but that is most often used as a backup if the tub loses heat (which happens). It’s also another expensive thing to buy, depending on its size.

It works on the same principle as a heater if you have an infrared heater. It uses infrared light rays to heat water and air.

With the air heated up first, it won’t raise the temperature of the water that much since it will go up very slowly.

You have to have a good filter for this kind of heater, which means having lots of water go in and out or filtering it before leaving for your hot tub session.

How Do I Make My Hot Tub Hotter Than 104?

You can make your hot tub hotter than 104 by jacking up the heater hose, so it’s a bit of DIY. But you can’t just leave it there. You’ll need to wrap the water heater in insulation, where things get tricky.

You’ll need sufficient insulation to get the job done, and that should be the only insulation for your hot tub.

So if you’re thinking about putting gutters on or painting your house, consider this in advance. If not, you have options, but these may not always be the best ones.

Depending on where you reside, there’s a good chance that while diving into your hot tub (after completing all other necessary pre-tubing tasks).

Most of the water will splash right on you and off into a nearby river or stream. That’s because hot tubs generally heat to 104 degrees, and it can get cold outside.

So here’s the trick to making your tub warmer than 104: Keep the wiring insulated using a swimming pool heating cable.

This type of cable runs underwater, and it stays flexible and insulated even when submerged.

You could buy a tub-plugging fibreglass blanket, keeping your hot tub warmer than 104. And if you’re excellent with a needle, you could make your own.

But if the hot tub will stay in one place, it makes more sense to wrap it in insulation. Wrap the hose and electrical cord and any tubing that might get exposed.

In addition to insulation, use a heat-resistant surface when heating your hot tub. This could be a metal surround or even something like this.

And still, if you live someplace cold and need to keep the hot tub warmer than 104, it’s a good idea to use a heat-resistant cover.

Alternatively, if you live in a reasonably warm area near the sea or surrounded by ponds, you might not need to insulate your hot tub. Just fill with water, plug it in and enjoy.

Why Won’t My Hot Tub Go Above 99?

Your hot tub won’t go above 99 because the heater is at 100 degrees Fahrenheit. That’s the default temperature for most Spas.

If you want to raise the temperature, turn up the thermostat inside the tub until you reach your desired setting.

You can also try lowering it when you’re done soaking or turning it down in advance of your soak time so that it doesn’t buzz as much while you’re trying to get settled.

Alternatively, a Spa might not have a heater and rely on an endless source of hot water from underground springs below them.

This is common in more remote locations, and it may be more economical on your part to buy a deeper tub than to upgrade your thermostat.

In that case, though, you need to decide if the maintenance of a deeper tub is worth the cost of heating it or not.

If you live where hot water is available 24 hours a day, you can set your thermostat higher before bedtime and lower it in the morning when you start using the tub.

Why Does My Hot Tub Say Heating Suspended?

Your hot tub says “heating suspended” because the temperature of the water is too low for it to produce any heat.

If your hot tub temperature is below 90 degrees Fahrenheit to 95 degrees Fahrenheit, when you turn on the power button, there will be a message “Heating Suspended.”

If your hot tub is below 60 degrees Fahrenheit and you want to use it, turn on the heating system.

Your system will come on if you try to use the Spa at a low temperature and keep the water warm enough for people to enjoy.

It’s important to remember that bacteria and other contaminants can grow if the Spa gets too warm.

If the Spa gets above 104 degrees Fahrenheit, you will need to shock it with a chlorine product made for Spas.

If the Spa stays hot for a long time, it may damage other equipment like pumps and filters. The average time you should use a hot tub is only 3 hours at a time.

To keep your heating system working correctly, check your filters often. If you see debris or black debris, you will need to clean or replace them.

You will also consider ensuring that the impeller on your pump is clean to move water through the system.

How Hot Will A Bullfrog Spa Get?

A bullfrog Spa is 80 and 140 degrees Fahrenheit, but many people like to set their Spas at 110 degrees.

Regardless of how hot it is, you’ll need to ensure that the water is deep enough for your frogs, or they’ll drown.

Bullfrog Spas are trendy right now, and understandably so, as they can be a great way to relax and unwind.

But while they might be unquestionably excellent when supporting a healthy lifestyle – bullfrogs can also prove troublesome.

There are some tough drawbacks to having a bullfrog Spa(Amazon Link) in your home. Namely, a bullfrog can become dehydrated when kept in too shallow water.

You’ll need to ensure it stays at least an inch and a half to two inches deep, no matter how hot it is.

Alternatively, you could go with a bigger bullfrog Spa. If you have the space, then a 140-degree bullfrog Spa is an excellent idea as you could use it for up to eight frogs.

But it’s not the only option for you – a baby bullfrog Spa is another great option.

A baby bullfrog Spa will be like a small pool and can comfortably fit at least three frogs.

Unlike their adult counterparts, which are often very large, one can keep baby bullfrogs in these Spas without worrying about drowning them.

They have well-developed lungs and can breathe air from the surface.

As with the adult bullfrogs, you’ll need to plan for a particular heat level for this sort of spa and ensure that it stays at around eighty degrees.

You can also build baby bullfrog Spas with a forty-five degrees gradient so that the frogs can move up and down, thereby ensuring that they stay safe from predators.

What Does PR Mean On Beachcomber Hot Tub?

It means that the hot tub has been pressure-tested to ensure safety for operation. Pressure testing involves filling it up with water and determining how much water you need to cause a leak.

Pressure testing is an essential part of the manufacturing process, especially when there are safety concerns about certain materials or designs that might cause rapid or uncontrollable leaking.

Hot tubs typically undergo pressure testing during various stages of production, with one final test done before delivery.

At this point, one repairs any leaks for the product to be final.

While pressure testing can be dangerous, you should not confuse it with blowing out the hot tub or unsuccessfully trying to clean the insides of your tub.

No matter what you are trying to do, you should always contact a professional technician and seek advice from the manufacturer’s customer service department before doing so.

Sometimes, even if there isn’t a leak, cleaning can produce irreversible damage, which will nullify any warranty you might have.

The word PR also stands for “product release,” as in the moment when a product is finally available to purchase by consumers.

What Does Sns Mean On A Hot Tub?

It means sensors are out of balance, and the system may need service.

If you have an electric hot tub, it’s good to regularly check the sensor as they can get dirty and clogged, causing the water temperature in your Spa to change frequently.

A clogged sensor will also mean more chemicals are being used, leading to expensive maintenance and eventual damage to your hot tub.

To check the sensor, adjust the jets in your Spa to their positions before turning it on, then add a little warm water.

Flushing the jets will flush out any debris clogging the sensor and should return your Spa to normal within 24 hours.

If your Spa checks out fine and you don’t see any problems, leave them as is until next time. On the other hand, if your Spa doesn’t check out properly, you must service the sensors.

Here are a few different problems that a clogged sensor can cause:

Bubbly water: This is a sign that the temperature sensor has clogged and cannot regulate the water temperature accurately.

This will result in your Spa heating and cooling periodically as you swim or sit in it.

Water level fluctuations: The temperature sensor allows your hot tub to know when it should fill with water.

Keeping a consistent water level can be almost impossible if this sensor gets clogged with debris, especially if your spa requires a lot of water to fill.

Hot tub temperature not staying steady – Because the sensor is essential for keeping the temperature constant, it will cause problems if you don’t service the sensor.

If you experience this problem, contact a professional that offers hot tub repairs.

Hot tub temperature is either too hot or too cold – When your Spa is running normally, it should maintain a specific water temperature.

If your water temperature has changed, one of these issues may be at fault.

If you see any symptoms with your hot tub, service the sensor and ensure you do a regular water level check to avoid running out of water.

Why Is My Hot Tub Not Circulating?

Your hot tub is not circulating because the pump isn’t running. You can identify if this is the case by looking at the top of the water, which should be a light blue color and not a dark blue.

If your tub is not circulating, try restarting the pump or turning it on manually by pressing and holding in those two buttons that look like (one on either side of a power button) until you hear it start making noises.

Check the circuit breaker near your tub if the pump doesn’t start. If it has tripped, flip it back on.

If you are still not getting a circulation, read on to see what is wrong and how to fix it.

First, check for obstructions that might clog the jets or the water flow through the tub itself.

If any part of your pump (the top in particular) gets covered in moss or an algae-like growth, you can use a jet cleaner to dissolve or remove these obstructions.

If you have any water flow or circulation issues, you can resolve this by replacing clogged things.

Next, check the circulation control box. This box near the machine has many buttons on it and a dial.

The switch to reset the machine, and an off button for both hot tubs and cold tubs.

The circulation control box should have a red light on top of it and a switch on the side that says ‘Circ. Enable’.

Flip this switch to one of the two settings: ‘Off’ or ‘On’ to see if you get a circulation. If you don’t, try flipping the switch back to its original position or resetting the control box using your hot tub’s manual.

Finally, check to ensure that no matter what setting your circulation control box is in, you have correctly positioned it.

You’ll want it on the front side of your tub and pointed outwards toward where the jets are. If your circulation control box is set to ‘On’ but not on the front side of your hot tub, you will have no circulation.

How Do You Fix A Low Flow In A Hot Tub?

You can fix a low flow in a hot tub in a few different ways. You may need to replace the Spa filter cartridge, upgrade the plumbing system, or replace the pump motor.

One way is to replace the Spa filter cartridge. When you are in the store, assess your needs for water volume accordingly.

There are two types of cartridges: high flow and low flow replacement filters that will provide you with a faster or slower stream of water, respectively.

Another way is to upgrade the plumbing system. You can purchase a new Spa pump that allows you to boost water flow into your hot tub.

If your hot tub has a flow control adjustment, this will regulate the water flow while you are in the Spa.

The final way is to replace the pump motor. Consider your local hardware store if you want to try this option first.

However, prepare yourself to pay quite a bit more for a Spa pump than you would for one already on the market.

Why Does My Hot Tub Say Low Flow?

Your hot tub says low flow because the heater is not set high enough.

Most tubs have a timer that you can set to the desired temperature, so it will turn on the heater periodically and then turn off when the temperature reaches.

To increase your flow rate, adjust your timer so that it doesn’t allow hot water to recirculate for very long.

This should result in a significantly higher flow rate and lower energy costs for heating water.

The most important thing to remember is that not all tubs have an adjustable timer.

In these instances, you will want to adjust the flow rate by finding your emergency solution, such as a temperature fault in your tub circuit.

If you don’t know the problem, or if the problem is not corrected, it will continue to repeat itself regularity.

Hot Tub Trouble-Shooting:

If the flow rate of your hot tub is low and the tub is not at maximum output, then the following steps should help you adjust it.

If your hot tub has several outlets, you can adjust to high flow rate by simply changing each outlet’s temperature or water chemistry settings.

1) Turn on all water valves (hot and cold) and fill the tub/s with water. You can then adjust the water temperature(s) to accommodate different users.

2) Wait until all jets are chilling and water is at room temperature.

3) If you have two or more tubs, always drain them simultaneously to avoid having one empty while filling the other with water.

4) Make sure the tub is at an average operating temperature. In most cases, this is around 100 degrees Fahrenheit in a tropical setting or 86 degrees Fahrenheit if you have a cooler climate.

5) Set the timer to allow water to flow through the tubs periodically. Each tub should have its own designated cycle time.

All tubs should run for about one hour to ensure proper cleaning and maintenance for each hot tub.

6) After setting and adjusting the timers, all your hot tub water should be flowing at an acceptable rate.

If it isn’t, there may be a problem with your circuitry or one of your valves or filters.


Hot tubs and 104-degree water aren’t for everyone, but if you want to relax or enjoy a little R&R, then it can be perfect for you.

It’s like having your pool; only you get all the benefits of sitting in hot water.


Hi! I' am Tom. I was a manager in one of the biggest stores for over 10 Years, am also an SEO by night. I don't like to call myself a blogger; they are very analytical, do email marketing, and know all SEO stuff. I faced many questions from customers about different products, and there was hardly any help on the internet. After learning all the things about these products as a manager the hard way, I decided to start a blog and help other people.
