Many people (well, by “many” I mean, like, five) want to know just how warm or not warm the Cold House is. Since we don’t have a thermostat, I can’t just answer “We set it at X during the day and Y at night.”
But we do have some digital thermometers, so over the past week I took to jotting down the readings every hour or two, when I was home. And now for your entertainment I’ve turned the data into a graph. Here it is:
Explanation: The scale is in ºF (sorry, centigrade friends– I could not do both.) Blue line: temp in our downstairs kitchen/living area. Red line: temp in the bedroom. Orange line: outdoor temp. Dashed lines: corresponding averaged temp, for the entire period, of each area.
Discussion: Outside, the weather during this eight-day period was standard-issue freakish New England. Early on we had a sudden thaw, with the temp reaching a very unusual 50º on Monday, tying a record high for the day. Two warmish days followed on Tuesday and Wednesday. Then things cooled off rapidly, reaching single digits by Saturday night and below-zero Sunday night. That is colder than “average”, but a more normal pattern.
Inside, the downstairs temps ranged from a brief low of 38.3º to a moment of hitting 69º. The overall average was 53º. The fluctuations appear to mimic the outdoor diurnal cycle, and there is some reality to that– but in fact they are more directly related to lighting a fire in the morning or mid-day, and letting it die by evening.
In the upstairs/bedroom, which is pretty much thermally isolated, the temps fluctuated much less. There the high point was 57º, and the low 37º (yes, we were in the bed when the room was 37.) The overall average bedroom temp was 47º. For the second half of the week, since the “heat wave” ended, it’s averaged more like 43º.
What to make of all this? I have no idea. Draw your own conclusions. And send us your own graphs!
