Weird OT mystery...

I'm sitting here in my skivvies, sweating. I turned the air conditioner off
an hour ago because it was getting cold in here.

This is November mind you. In the mountains of Virginia.

It got up reasonably warm today, maybe 70-something. It rained a lot, and
was generally overcast. Not very much solar radiation getting in to warm
the place up. Around 10:00 PM the heat became so intolerable that we
actually turned the A/C on and let it go for around half an hour.

So now it's about 1:00 AM. Somewhen between then and now the air has picked
heat back up from somewhere, and I'm scratching my head trying to figure it
out. It's back up to 81 degrees in here, and it was down to 71 at 10:00
PM. No sun in that time. No electric heat, no propane heat...

Could be waste heat from the big dehumidifier that has been chugging 24/7 in
the crawlspace for the last six months maybe.

Residual from the hot water heater that really needs replacing very soon
now.

Halogen lights...

Still, adding all of this up, it's about 1500 sq. ft. of open space in here,
and it would take a lot of BTUs of heat to raise that much air by 10
degrees.

Could it be a simple matter of body count? House empty all day, then four
big'uns, two little'uns and three furry'uns? (Three medium sized dogs.)

I won't be complaining about free heat in a few more weeks, mind you, but
it's a real mystery. I'm wondering if I have some problem developing.

I think your numbers are correct but it is BTU per hour. Not trivial
but not a huge source. my house here in NC gets much warmer after
sunset. the heat trapped in the attic tends to start leaking into the
living space after about 10 hours. Insulation only works so long. It
is a cathedral ceiling so no way to exhaust the waste heat.

I do have a 1 GHz AMD box that runs 24/7 and makes this room toasty, but the
rest of the house was pretty toasty too. Same thing again this evening,
actually.

Must be body heat.

*Everything* contributes.

I forget how many BTU/hr a person puts out, at rest, but _occupied_ school
buildings almost -never- run the heat plant at temperatures above *MINUS*
*TWENTY*FIVE* Farenheight. The warm-body factor is enough that they're
dumping heat to the outside.

Other things, like the _refrigerator_, the dehumidifier, lights, the TV,
computers, etc. -- they all add up. non-trivially.

Betcha you've got several kilowatts of electric load that you don't even
-realize- are running.

Plus all those "warm bodies".


An additional point -- *rain* releases _tremendous_ amounts of heat into
the atmosphere. 1" of rain, over a medium-sized city, say one the size
of Omaha, NE, releases more total energy than a mid-size atomic bomb. Not
from lightning, etc. -- just from the reverse 'heat of vaporization'
released by the water-vapor condensing out.

Now, +most+ of that heat is released at higher levels in the atmosphere,
and you'll freqently get some 'evaporative' cooling at/near ground level.
but, it's not uncommon for ground-level temperatures to climb by several
degrees, several hours after the rain.

I suspect that may be your real problem. If the humidity is high,
water isn't evaporating from your skin, thus you aren't benefiting from
natural cooling. 81 and dry is pretty comfortable, 81 and humid might
be pretty uncomfortable. Did you say you have a de-humidifier? Is it
running?

Huh?! I am the Business Manager for a school district near Pittsburgh,
PA. It NEVER gets to -25 F here. I don't think it even went below 0
last winter. We seem to run the heating systems all winter though and
spent a total of $350,000 for natural gas last year for 9 buildings. I
doubt that body heat can do much for heating significant spaces and if
there were enough bodies in the space to heat it when it is -25
outside then the CO2 being given off would kill everyone if there
wasn't a MAJOR fresh air exchange going on...not to mention the smell
;)

That's more in line with the number I remember from one of
my engineering courses many decades ago.
The human body at rest generates ~100W of heat. An active
body generates more but I don't remember how much more.

Body heat sure adds up. I used to work for a company that built heating and
AC units for commercial and industrial applications. Schools were one of
their largest markets.

Body count is very seriously taken into consideration when calculating heat
loads. IIRC, it is 485 Btu per person. or enough heat from 100 people to
heat a small home.

Ever go to a concert or sports game in an arena? Notice how cool it is when
you first arrive and how much warmer it is when the crowd fills the place?
And yes, air exchange is also considered. Often the heat is off and the
ventilation is bringing in the cold outside air to cool the place down.

I've got numbers ranging from 450 (sleeping), to 570 (hard work). I know
that that second number is somewhat _conservative_. For rough calculations,
and 'average conditions', 500 BTU/hr/person is a reasonable approximation.

Guess it depends on what you consider a 'small home'. The house I grew up
in was about 1200 sq ft on the main floor, 2 stories over 25% of the space,
and unfinished basement under about half the main floor. Due to 'accident'
of incremental construction, the place had _two_ smaller furnaces. one
rated at 48KBtu/hr 'net', the other at 64k net.

One winter, one of the furnaces *died*. We don't know just when, we -noticed-
"something unusual" during a viscious cold spell (daily highs circa -20F, lows
below -35 F brrr!). The "big" furnace was running nearly continuously.
about 50 minutes out of each hour. Vs. a normal 12-15 -- maybe 20 in really
cold weather. Went looking, and discovered the other furnace wasn't running
_at_all_. So we've got the _one_ furnace, 64kBTU/hr, running at about an
85% duty cycle, keeping the _entire_ house comfortably warm. In *sustained*
-25 F weather.

Call it about 55k BTU/hr effective, from the furnace. For somewhere between
1600 and 2200 sq ft of 'livable space', depending on how you count things.

Four 20'x20' classrooms (1600 sq ft total), with 30 people/room, produces
around 60K BTU/hr of 'people power'. The 'energy' _is_ there to keep the
place warm at -25F, without requiring supplemental heat. <grin>

It is also humid under the conditions we've had the past few days adding to

I seem to recall from my college days (engineering school), the rule

Check your heating system. A few years ago my BIL had his go berserk in
the middle of summer. Heater kicked on permanently and as the AC side was
able to maintain the temperature on the thermostat he had no idea until the
electric bill came in. Repairman said the controller shorted out somehow
and the strip heatrers in the unit had been running 24/7 for while.

Same thing happened to me last night, and my friend at work and

Yep, kicked in around 10PM last night. Even my wife thought it
was hot, and she almost never thinks it's too warm.

<snip list of possible localized causes>

Whatever it was, it wasn't just you and your place. It was
happening on my side of town too.

I'm guessing some sort of atmospheric pressure change combined
with the humidity.

I could have done a lot worse, so now I will. Somewhere on the web there's
a picture of me floating around, wearing nothing but a sock and an electric
guitar.

*That* ought to keep you up at night.

That tears it then. It was definitely the alien microwave thing. The

Or maybe that. :)

Anyway, it makes me feel a lot better to know it wasn't just me. If you
live in Blacksburg somewhere, you're bound to live several miles away, so
it must have been a big atmospheric flummy.

Dave,

The old science building at the University of Pittsburgh at Johnstown (built
in the early 70's?) was so energy stingy, they only had to run the heat
during the Christmas break ... because there weren't any bodies to keep it
warm. Rest of the time they had a heat surplus without the stale air
syndrome.

Also ...
http://www4.ncdc.noaa.gov/cgi-win/wwcgi.dll?wwevent~ShowEvent~206153 shows
record low temperature for Pittsburgh area ... pretty close to -25!

Nah, there'd be steam. My dehumidifier has been going 24/7 for months, and
it's still moist down there. No longer quite so dank, but still irksome.
Gotta get that in check before I have to figure out how to replace all my
joists.

Would have taken longer than 5 seconds if you'd married her.

Good thought, but it wouldn't distribute the heat without the fan running.

Maybe it's just down to dog farts.

Possibly. I seem to recall reading that the heat output of an adult human is
around 500 watts asleep, and 750 watts awake, but I could be imagining that.
Dogs have a higher body temperature than humans, too.

Well, you might. Does anyone *else* think it's too hot? 81F isn't hot IMO.
That's a comfortable-in-tee-shirt-and-shorts kind of temperature, not a
sweating-in-your-skivvies kind of temperature. If you're the only one
sweating, it might be time to call a doc (or at least get out a fever
thermometer). Have you been drinking enough water?

SWMBO stripped down to her skivvies too.

No, unfortunately, that didn't lead anywhere interesting. :(

The kids both kicked off their covers. It wasn't just me.

Maybe we got microwaved by aliens from another galaxy. :)

Just for kicks, do a rough estimate of the volume of the space David
Blaine occupied in that block of ice. Then using 2500Cal/day as a rough
first-pass, figure out what the temperature of the air in that small
space was. Heck, be generous and say he only put out 2000Cal/day.

Plus, he was given hot soup to eat.

Nice work if you can get it, assuming one isn't claustrophobic.

n.b. that keeping himself dry and keeping bare skin away from wet ice
were nontrivial concerns.

Brick house? They can retain quite a bit of heat within the bricks for a
few days. That or a very-well-insulated house and all them bodies....

Did you turn the oven off? ;-)

I have my computer in a bedroom converted to an office. That rooms stays
pretty much five degrees warmer than the rest of the house just from heat
generated by the computer. If you have a computer over 1Ghz, particularly
an AMD system, it doubles as a room heater. Ditto for an inefficient
computer monitor.
