  • Hot tub winter

    We are new to the wood fired hot tub, we just completed it this September. This is at our cabin in the mountains that can get 6ft of snow and temps around -10 to-20 Celsius. I have read that draining to a few inches is good or I like the idea of using the suspended milk jugs. It is a 6x4 tub, what would be recommended amount of jugs to ensure no damage to the tub if it freezes. We would like to use it approximately once a month in the winter and not too keen on having to empty and fill. Everything is run off generator or solar, no electricity.

    Thanks for any advice.

    Hi Tree Witch, If your solar is used to generate electricity you could possibly consider using a stock tank heater. They have a relatively low draw, 1kW or so. If that is possible, then the question would be if there is enough sunlight to run the stock tank heater. That is a bit of an unknowable as temperatures and sunlight are highly variable. There are other methods of dealing with freezing. See our FAQs at
