Frozen Hot Tub: Do These Steps Immediately

Frozen_Hot_Tub_Do_These_Steps_Immediately

Winters can be very cold indeed, so you should take special care of your home, as well as your hot tub. However, since winter is also unpredictable, it is no surprise that your tub can suddenly become frozen overnight.

You may forget to turn it back on after cleaning, or someone else may turn it off. Either way, your tub can get frozen in cold weather if it is not running. But, you should not worry since the issue can be easily solved. In this article, we will show you how to take proper care of a frozen hot tub.

Frozen Hot Tub Prevention

  1. Set a Temperature Alert. You can use one of many hot tub apps to monitor the weather. If you see that a cold period is coming, make sure your spa water temperature is high enough. This way, the tub temperature will always be in sync with the weather and you will prevent freezing. What’s great is the fact that there are many free apps out there.
  2. Freeze Protection. Some types of spas come with freeze protection. But, if you have an in-ground spa, that might not be the case. You can install a digital time clock or even a digital spa pack. This will make sure your system runs the pumps whenever it senses low temperatures. Doing this will prevent freezing and can save you lots of trouble.
  3. Keep the Spa Running. It is never a good idea to turn off your tub or keep the temperature below 90 degrees Fahrenheit. The optimal spa temperature in winter is 100-104degrees Fahrenheit. If you heat the tub to 100 degrees Fahrenheit and put the cover on, it can remain warm for 24-36 hours in case of a power outage. On the other hand, if your tub is not heated, you could notice a frozen spa in a few hours.
  4. Don’t Remove the Cover. If you remove the hot tub cover for just a short period, this can cause the water to start freezing. So, always keep it on, especially if the temperatures are really low. Also, make sure your cover is properly placed and there is no chance for heat to escape. This is a crucial step in preventing water freezing so you should never skip it.

How to Unfreeze a Frozen Spa

  1. Turn it off. If the pumps cannot move the tub water, you should shut off the power until the ice melts. You could also put the cover on so it happens faster.
  2. Break the Ice. Attempt breaking the ice on the surface by adding some hot water. You can either use a garden hose, or buckets full of water.
  3. Thoroughly Inspect the Tub. Use a flashlight or a utility light to check the tub. You should pay close attention to the filter, pump, pipes, and heater to see whether there are any cracks.
  4. Utilize a Heat Gun. You can either use a heat gun or a ceramic heater that can be placed under the tub cabinet.
  5. Use Blankets. You can hold additional heat by using heavy blankets if needed. Also, you can use thermal covers that are specifically designed for hot tubs.

How to Recognize Freeze Damage

Freeze damage can usually be noticed in the heater, which is typically a cylinder made from stainless steel and is also mounted horizontally. Also, it can appear on the filter lid or body, which is a vertical cylinder made from plastic, which serves to hold the filter cartridge.

 Besides, it can be noticed on the pump lid or body. Pipes, on the other hand, tend to crack in a spider-web form, and they shatter through fittings or along the lengths. In case you notice any damage, you should call a professional who can replace the damaged part or fix the issue. This should be done as soon as possible to prevent further issues.

This depends on several factors, such as water temperature. If the tub water is 100 degrees Fahrenheit and the cover is on, it can take 24-36 hours until it freezes. On the other hand, if the water temperature is lower than 28 degrees Fahrenheit, it can freeze in around 36 hours.

Q: Will an Empty Hot Tub Freeze?

A: 

Empty hot tubs can freeze if there is any water left in drains. You need to be extra careful if your tub has external drains. They can freeze quickly and in turn break, which means they will let the hot water out. This should be prevented because hot water prevents the tub from freezing.
