Temp graphs - indoor with coal, & outdoor

PostBy: SMITTY On: Sat Dec 20, 2008 3:47 pm

This isn't a real good example because the temperature swing last night was only 10*F, but you can still see how steady coal heat is. It's almost a straight horizontal line -- just 1* of fluctuation! Not bad for most of the heat turning snow into icicles & dams on the roof!

The unit I took the pic of is a Davis Instruments Vantage Pro2 home weather station. No - :fear: kids :fear: - here -- so all toys are bought for me! :up:

Here is the outdoor temp.. Note the graph at left -- each dot horizontally represents one hour for 24 hrs., vertically, 2 degrees.

Indoor temp..Vertical is 1 degree instead of 2. Now compare this graph with the outdoor graph! Coal is nice & steady!

You're doing the right thing. Buy all the toys first, everything the lastest and greatest. Then when you get them outta diapers and on table food you're golden. Three years and you got it aced.........

Smitty, I have a Davis too. About 4 or 5 years now. The indoor temps reading on the Davis will stay constant as it is designed not to graph subtle temp changes such as you may see in a normal home. I have straight lines year round. The wind graph shows the most changes but only on gusty days.

Place your Davis on top of your stove so we can see how high your console will read. :lol:

If I can avoid them altogether, THEN I'll be golden! :lol:



Hey Cap,

You first! :lol: I have the wireless one -- not cheap! ;)

My house isn't normal :lol: -- before I put in the Mark III with the water coils, I'd see temp swings in here range from 56*- 64* with outside temps in the 20's or lower. When I'd go to work, the oil heat would be off & the old Mark I would be struggling to maintain 56*, while the TV room would hit the upper 40's & the top floor hitting the low 50's! I don't miss those days! Now, the TV room is 68*- 70*, as is the top floor.

But, I'm going thru coal at an alarming rate -- I'm hoping I don't run out before winter is over! :o

Right on Smitty, i've got three boys all grown up and moved out and they are still a pain in the ass from time to time.

Have i told you lately how much i like this coal burning stuff. i really really like this coal burning thing and i don't need fancy instrumentation to tell me my house is nice and toasty, i just have to be concious. :lol:

Darn, that's cold. Did you use a refrigerator to keep the milk & beer cold or just leave the case out on the floor by the TV? :lol:

I got the wireless too. But its placed on an external wall therefore always reads a few degrees cooler than actual air in room.
I have the anemometer mounted at top of my auxiliary flue measuring winds. And I see good winds where I am positioned at the top of a hill with the Lehigh Gap just NW on me. Highest recorded gust so far is 56mph. Many more in low 50's mph. Doesn't sound real high but winter around here typically brings high continuous winds. It's crazy.

I actually have done that once or twice when the fridge was full! :lol:

Sounds like you have the same unit we have. It has the rain gauge,barometer, hydrometer, anemometer -- I didn't get the fancy leaf wetness & UV detectors. It's also got the solar powered fan so the heat from the roof won't throw off temp readings -- it's a neat unit! ;)

You got us beat on the wind speed -- sounds like an ideal location for the anemometer. We just had our highest recorded wind speed last night @ 1AM. 45mph.10 minute average speed was 14 last night with the warm front that came in.I have the unit mounted on my roof, but we have a hill in my backyard & lots of trees -- not an ideal location. For the last year, the highest was 39mph -- & at the instant it registered, our power went out for 24 hrs! :lol:

Last summer we recorded a rain rate of 11.42 inches/hour! :shock:

Here's some pics from 2011. Keep in mind that one graph's scale is 3° per line, vertical, while the other is 1° per line - so the change is actually more dramatic than the graph shows. The pic will show the scale - you'll see a 1 or a 3 below the graph, but above the min/max temps.

On the indoor graph you can see exactly when I lit the stove. While the temp plummeted outside, look how quickly the temp rose inside - but then look at how ROCK STEADY the temp stayed. Horizontally ( left to right ), the graphs are from the exact same time frame. Each dot is one hour back from the right - 24 hrs total. All this with howling winds & crappy windows & insulation.

If anyone's on the fence about coal heat, this should seal the deal for ya! :cheers:
