We live in NW Montana, where it’s currently snowing lightly and the temperature is 7 degrees F, with the expected high today of 16 degrees F. We have a 6 person hot tub that sits outside on our deck and we keep it running at 104 degrees F throughout the year. It has a hefty, tightly fitting insulated cover on it.
Since we haven’t used it in the past few days the snow has piled up on the cover. There’s about 8 inches of light powdery snow sitting on it right now. My wife asked me last night if I should brush off the snow, but I said no since it was providing additional free insulation. (I know a pile of snow is mostly air, so I figured it would actually help keep the hot tub from losing heat to the cold night air).
This morning I woke up and realized that since the snow was cold it might actually conduct the heat away faster than not having the snow there. :smack: Or will it?
So which is it? Does a thick layer of powdery snow help insulate the hot tub, reduce the insulating capacity of the cover, or make little or no real difference? And yes, I need a hobby…
