Frozen Hot Tub

At only 8″ tall this heater can thaw frozen hot tub pipes and save you a lot of money

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 days, which I highly reccommend, 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.

What I am going to suggest is basicly 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 froze. At the time I am writing this the tempature 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 yourselfer or waiting for a service person to show up, I reccomend 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.

  1. Froze. Thawed with heater. Replaced primary pump ( bad). Filled 1/4 started to leak somewhere underneath. If it’s a hair line crack how will I ever see it without propping it up and filling again. You know how heavy any other first step ??…. m

    • If you are noticing the leak at only a 1/4 of the way full it is more than a hairline crack. You should be able to find the leak without lifting the tub. If it is a full foam insulation tub you may have to start pulling out some of the foam. I would start around the manifolds first. This is where the large line from the pump splits off to all the smaller lines that lead to the jets. This will usually be one of the lowest parts of the plumbing and usually breaks first.
      Good luck
