How you care for your wood-fired hot tub in cold weather conditions depends on how often you use your hot tub and whether or not electricity is available. If you are using the tub at least once a week, you should be fine in all except the most extreme weather as the water (with appropriate covering) shouldn't lose more than about 15-18 F degrees per day. You do, however, want to avoid having the entire tub freeze solid as this could cause severe damage tub.
If I am not using the hot tub regularly, how can I prevent it from freezing?
If you will be leaving your tub unused for extended periods of time in freezing weather, here are some things you can do to prevent damage to the tub from freezing:
- If you have easy access to electricity, a standard tank heater is the most simple, inexpensive and effective solution to keep the tub from freezing.
- If water availability is not an issue and you can easily refill the tub, then drain all but 4-5 inches of water. This small amount of water can freeze as few inches of ice won't hurt the tub. When you are ready to use the tub simply top it up with water and fire up the stove.
- If water to refill the hot tub is not readily available, you can submerge an inflated inner-tube with weight (like a cinder block) and rope and sink it to the bottom of the tub. When the water freezes and expands the inner tube acts as shock absorber so the tub walls aren't damaged. Make sure the inner tube is completely submerged near or at the bottom of the tub.
- If you do not drain the tub and notice a few inches of ice on the tub surface, just start up a small fire, and let the stove heat slowly. You can allow several inches of ice to form on the surface of the tub without doing any damage.
- If the tub does happen to freeze completely, caution is advised. You can melt the ice by starting a fire, but a fast burning fire quickly melts the ice around the stove. The water can then boil away exposing the stove to air which will cause the steel to melt. Without water surrounding the stove it could melt. We recommend adding some water to the top of the frozen surface while melting the ice. You should try and heat your tub up at least once a week, and of course, heating it up means you get to enjoy it too.
