Frozen Hot Tub

If you own a hot tub and live in a cold climate, having your tub stop working in the winter can be an expensive problem. Not only do you have to worry about finding out why the hot tub isn’t working, but also you have to worry about it freezing and causing more problems. Broken plumbing in a hot tub is an expensive repair (especially in a full foam hot tub). Replacing a wet end on a pump or a heater because of freezing and breaking is very costly also. Even if you check on your hot tub in the winter every couple of days, which I highly recommend, you have to be able to either stop your tub from freezing or stop a tub that is frozen from going farther and breaking anything.

Frozen Hot Tub

What I am going to suggest is basically an insurance policy that every hot tub owner in a cold climate should have. It is a $10 to $15 investment that could end up saving you thousands of dollars in the long run. It is a small electric ceramic heater. In the winter I carry two of these heaters on my service truck. They allow me to keep a hot tub from freezing while I am waiting for parts to be shipped in or to thaw a hot tub that has already frozen.

At the time I am writing this the temperature outside is 8 degrees with a wind chill of 10 below zero. I have a ceramic heater under the skirt of a hot tub that is waiting for a pump to ship from Canada. I am confident that the tub will not freeze in the week that we are waiting. I have also worked on hot tubs that were frozen solid. After having one of my heaters under the tub for 3 days it thawed and needed only minor repairs.

So whether you are a do-it yourself or waiting for a service person to show up, I recommend buying one of these heaters. Most hardware stores sell them for $10 to $15. They are very small, only about 8 to 10 inches high but heat very well. You may never need one of these heaters but if your hot tub does stop working in the middle of winter you’ll be happy you have it.
