5 Reasons Your Hot Tub May Not be Staying Hot

Hot tubs are amazing features to add to your backyard. They have dozens of health benefits like muscle relaxation, sweating out toxins, and overall stress relief. Hot tubs are also great for throwing parties and spending time with your family.

However, sometimes hot tubs do not stay as hot as they should be, which can put a big damper on your hot tub experience. This is a problem that should be fixed so you can enjoy your hot tub again. Unfortunately, it can be difficult to figure out the reason for your hot tub not staying hot. This is because there are many reasons this issue could be occurring. So, look for the common reasons listed below to make the diagnosis a little easier on your end.

Damaged Hot Tub Cover

One of the most common reasons for hot tubs failing to remain warm is because of damaged hot tub covers. It may be surprising that this is such a prevalent issue, but hot tub covers are very important. Hot tubs are supposed to be warmer than the outside air temperature. So, when a hot tub cover is not properly insulating the warm water inside the tub, the air temperature cools it down. Your heating system may be strong enough to combat the cold air, but this will waste a great deal of your electricity. It is crucial that your hot tub cover has no holes or rips, and that it is securely fastened to the hot tub.

Another reason you should have a damage-free hot tub cover is that it will prevent rainwater from entering the hot tub. Rain is obviously much colder than the hot tub’s water, which will cause it to cool down when it enters the tub. The water from the rain will also disrupt the chemical balance of your hot tub’s water, which presents yet another issue. So, if you have any damage to your hot tub’s cover, you should take steps to fix it, or replace it altogether if needed.

Broken Temperature Sensors

If you know your hot tub cover is in perfect condition, you likely have another problem with your hot tub. Your hot tub could have broken temperature sensors, which are telling it to not heat up as much as it should be. Inside of your hot tub, there are heat sensors that control the water’s temperature just like the thermostat inside your home. If these sensors are broken, they could be reading your hot tub’s temperature wrong, thus not telling it to heat up when it should be. Clearly, this is an issue that needs to be fixed, so you can enjoy a warm hot tub again.

Unfortunately, broken temperature sensors are very difficult to fix on your own. It is best to call a professional hot tub technician to fix your sensors if you believe they are the problem. This will help save you a lot of time, and it will ensure the sensors are fixed properly. Once the technician fixes your hot tub’s temperature sensors, you will be ready to enjoy your hot tub again!

Water Circulation Issues

Another issue your hot tub may be facing is water circulation. If you have noticed less movement in your hot tub, especially when its jets are on, your hot tub could have some water circulation problems. Water circulation is very important in hot tubs so the warm water can travel and mix with the colder water. So, if your hot tub is not circulating its water, this can cause the temperature of the hot tub to drop significantly.

To fix this issue at home, you should check your hot tub’s filter. See if the filter is clogged and if that is the reason the water is not moving. If that is not the issue, you may have something blocking its impeller. It is normal for debris to get trapped in the impeller and block the water flow. Just simply remove the debris, and this should fix the issue. If you are unable to fix the water circulation in your hot tub by yourself, you may want to call a technician to see if they can fix it.

Too Low of Outside Temperatures

If your hot tub is warm when you get into it, but after time you notice its temperature drops significantly, there may not be a problem with the hot tub at all. The outside temperature may just be too cold for your hot tub to heat up. In climates where it gets to be below 10 degrees Fahrenheit, it can be extremely difficult for your hot tub to stay warm. Even the most expensive, top of the line hot tubs with the best motors can struggle to keep up with harsh temperatures. Being exposed to such cold temperatures causes the heater to have to work overtime, and it may result in the hot tub dropping a few degrees. However, this is completely normal, and it is not a cause for concern. As fun as sitting in the hot tub on a snowy day may be, give your hot tub some leeway if it struggles to stay warm.

Old Age

If your hot tub is over 10 years old and it hasn’t been able to heat up like it used to, old age may be the problem. Just like with most appliances and technology, hot tubs become old and worn out. This is especially the case with hot tubs that have been cheaply made and were not built to last for many decades. The only solution to this problem is to purchase a new hot tub if you would like to continue using one.
