Yes, that is the very point. Some people call it "thermal flywheel effect", although there are no moving parts. A closed chamber filled with water is sometimes used.gyre wrote:Elliot, a warning about thermal mass.
It will always have a slow rate of change, even when the weather doesn't.
Which is why a living space with it can be so comfortable. Very stable interior temps. Even if you have a door open for a few minutes when it's cold outside, once you close the door you've lost most of the hot air out of the house, but the thermal mass quickly reheats both you (radiant) and the air.Elliot wrote:Yes, that is the very point.

My barn floor consists of 31 cubic yards of concrete. On a scorching summer afternoon it is still cool to the touch, keeping the work environment cooler than outside in the shade.
Conversely, in winter, a house that is warm during the day will not drop to freezing by morning if it has plenty of thermal mass. (As opposed to my almost mass-less trailer house which turns into an ice box overnight.)

AntiM. I need a jolt, working from home again this weekend and plunged in over my head already, yikes.

Ygmir, you have a crane? Cool.
I spent the last 3 days demoing part of a very famous stage in Hollywood. Much improvised crane work, with a gradall and chain motors.

If you had that much TM, you sure wouldn't be able to turn the thermostat down much for night, and back in the morning, as the lead times to reach your target temperature are too long. Although, for smaller amounts of thermal mass, there are learning thermostats, and computer programs, that can be given your target temps and they learn what lead times & temps are required to reach those targets for different outside conditions.

Very nice job.ygmir wrote:*screen wipes, please***************hahaa nice one Sav!!
so, I was asked to help the Jewish historic cemetery people with an issue, at the local cemetery of theirs, I had done work on:
It seems several of the "crack head" neighbors, have taken it upon themselves, to use the cemetery property, not only as a "more convenient for them" driveway (they have their own, but it's longer), but as an easy place to throw garbage, trash and brush.
When asked to stop, they cussed and were totally disrespectful to the older folks on the committee, who obviously could not counter this verbal abuse.
I was asked to come up with them and help find a remedy:
when I was there with these folks ( in their late 70's kind, and polite to this ass) this neighbor called us all "fuck heads" and said "you'll not block me, from going anywhere I want"..............well, with so many witnesses there, I just remained silent.
The folks were very upset, saying he has also threatened them with his pit bull dogs and masked friends to intimidate.
I said, "trust me, I'll block the drive, and happy to help"
They asked "what will you do"?
and I replied:
"don't worry, I'll stop this, and no one will get hurt, unless those folks really beg"
They are very concerned these crack heads will hurt someone, either themselves or by sicking their dogs on them.
I called a friend with two dumptrucks, and we loaded 3500 lb. blocks of concrete, 5 on each, and went there at 7 am.
in 10 mins, we dumped in a grid, these 10 blocks.
"yeah, crack head, you're right, no on will block your drive"...........and no one got hurt!!
I sent these pics to the cemetery folks:
we're gonna keep watch on the car though?ygmir wrote:haha very nice GH!!
we're hoping to see ya, on the excursion to Gerlach next Sunday!!!
yeah, good call Elorrum! if we see one of those huge forklifts, or any large machinery, with a hysterically laughing goat driving, I'd say we're in trouble!!Elorrum wrote:we're gonna keep watch on the car though?ygmir wrote:haha very nice GH!!
