To summarize so you don’t have to read the whole thing:
-Can you use one salamander/torpedo heater to heat a 12’x6’x4’ OSB-framed kiln to a minimum air temp of 150 for at least 4 hours, for the purpose of killing anything alive?
-Will the power of the heater matter much? Or is even the weakest of these heaters capable of creating an air temp of 150 inside this box?
-Do I need to vent the box? I want as much heat to stay inside as possible.
I have a stickered stack of reclaimed lumber.
I know there are some wood boring insects inside, (a recent infestation). Grubs/eggs or whatnot.
Kill ‘em with fire.
150-200 for 4 hours ought to do it.
Build a makeshift kiln around the stack.
Four walls and a roof made of cheap osb on a 2×4 frame.
Dimensions of stack: 12’x6’, rising to approx. 4’ off the ground.
Looking for effective, cheap, easy, safe.
In that order, lol.
My current options in order of my preference:
1: Salamandar/torpedo heater
$20 to rent from HD. Won’t actually place in the box, but place it maybe 3’ outside. The business end sticking into a “tunnel” of cinder blocks leading into the box. This way, no actual wood is in contact with the heater.
Possibly add a fan, if air circulation is lacking.
2: Small fire in a circle of cinderblocks, just outside the box, venting into the box.
Definitely need a fan inside the box. Definitely need to keep a sharp look out for safety.
3: Steam. Rent steam cleaner from just about anywhere.
-Warping of OSB box walls, releasing the heat.
-Saturating the wood. I believe the steam would actually lower the RH of the wood, but I’m no expert.
-It kind of seems like going around my * to get to my elbow. The other two options involve ONLY a heat source, where this option uses a heat source to heat a 3rd party substance, to then heat the wood.
However, steam is a common way of killing insects/sanitizing.
-Not as cool/satisfying.
Thank you for taking the time to read this.
You guys, and this place, are awesome.
