Can I foil wrap a brick in the OBS?

richardvoyageur · June 15, 2011, 11:28:43 AM

Hi guys, I've been noticing some slow temp recoveries after opening the door and wanted to even that out with a brick. I know a lot of you guys do it here as well, but I was wondering if I can foil wrap the brick. I know somewhere in the booklet it said not to foil wrap the walls for some reason and that it could break something.

Just want to make sure I won't blow anything up! :D

Yes several members use a foil wrapped brick inside of the OBS

Yep !!! serves as a heat sink...

Yes you can but some find that a larger water tray (filled with hot water) works better.

I do both (brick & hot water in larger tray) It works.

I use an old Lodge case iron skillet (the square one) in mine. Just lop the handle off so it fits - and you can put in a small foil brownie pan to act as the water pan.

I currently use two small bricks on bottom and two on top shelve and it helps.

I am interested as to why adding more water than just the bowl would help with this.

Well I ain't exactly Mr. Science, but the way I understand it is that since water has a higher heat capacity than air, sand, or brick, a space filled with heated water requires relatively less energy to maintain temperature and therefore allows more of the energy from the heating element to continue to heat the rest of the cabinet. If you have more water (bigger pan) it fills more of the cabinet and requires correspondingly less energy to maintain the temperature of that part of the cabinet. Or maybe it's just magic.

I vote for the magic. ;D

Thanks for the explanation

I added the 2nd element so - Bricks?I don't need no stinkin' bricks

I've been using a pan with near boiling water to keep the temps up but I am going to go to bricks so I don't have to babysit it.

Yep, second element is the way to go. Mine preheated to 225F degrees in just 8 minutes the other day, with an outdoor temp of 70F degrees. Chamber recovery temps are even faster. No stinkin' bricks needed here, either. ;D
