First snow

The forecasts of snow were fairly accurate for once. We got about an inch starting late Friday night.

Along with the snow came the cold. We measured 16F this morning, and the temperature never exceeded freezing during the day. Now, as I write this on Saturday night, it’s 19F and headed down.

We didn’t have any place to go during the day, but we did have an errand to run later. By the time we left at around 7 pm, the sun had cleared most of the snow and ice from the roads. We made it to our destination (the mall) with no problem, but it was closed. Around here, a rumor of snow results in widespread closings, especially since 2014 when Atlanta turned into a frozen parking lot after a little snow fell.

We have not used our wood-burning stove much this season, but we’re using it now. It’s taking some getting used to. In our old house, we had a big stove in the basement. It took large pieces of wood and lots of them. The new stove has a very small firebox, so it takes short pieces of wood split much smaller than I am used to, and it needs to be fed more often.

But the stove is keeping the living room comfortable, and the forced-air duct I installed is helping to keep the bedroom warm, too.

Here’s the stove in action.

The two sheets of metal at the sides and the sheet of metal below the stove are my additions to help keep the walls and floor cooler. I hope to make them a little more finished at some point.

I had originally intended to paint the metal black, but I’m considering not doing it now because of a reason that I find really interesting but probably no one else would. As we all know, we see in visible light. The heat that we feel coming from a wood-burning stove is just like visible light, but it has a longer wavelength and we can’t actually see it. We call that infrared radiation. We also know that dark objects absorb visible light and light objects reflect it. It turns out, however, that most objects, whether they look dark or light to us, are “dark” in the longer wavelengths of heat. Even white paint that reflects visible light still absorbs long-wavelength radiation. If you could see in the infrared, white paint would look dark gray.

One of the few common materials that reflects heat is shiny metal. Those plates are made from shiny metal. They don’t absorb heat, they reflect it. So even when the stove is putting out lots of heat, the metal plates right next to it are barely warm. It’s contrary to our intuition, but that’s physics. I find that cool, too.

  1. Wow! You got your snow. That is so cool (pun intended). Love seeing your woodstove and that very informative physics lesson. We had a chimney sweep come out and clear out some serious cobwebs in our chimney. We had our first (and only, so far) fire the other day. It was nice, but we sure do miss our woodstove.

  2. We got four inches of “your” snow (i.e., from the same storm) in the northern Piedmont on Saturday, Mark. That was on top of the three inches we had gotten earlier in the week from a previous storm. We’ve also had the coldest nights of the season so far over the last few evenings; on Sunday morning it was 10 degrees when I got up at 7:30 a.m.

  3. Robin — It was pretty cold here so we have kept the stove going continuously, at least until Tuesday, when it started to warm up. We are expected to have highs in the 60’s and even 70’s for the next week.

    Scott — Our snow lasted a while because of the cold. We measured 12 degrees up here one morning. Of course any place the sun could shine, the snow melted in the first day, even with the below-freezing temperatures. It really wasn’t much snow.
