ok so how do you identify or determine what is real actual fire brick vs just regular building/construction brick, anyways??? because i am looking at putting in a wood burning furnace, with blowers and dual heat vent pipes,, on basement concrete slba floor and against a regular 1950s/era block wall, but I'd like to brick a pad on the concrete slab in the area where the furnace will be.
also what is the best ay to protct sheld the ceiling/floor joists above the furnace area?
the exhaust vent pipe flue will be going out throguh the block wall directly above behind the furnace, there iis already a large round, 8" or so, vent pipe hole for this ready to use. from an old 1950s stove or something, that was in existence in this same location, back in the day,,.
at the garage we have a wood burning furnace like this that was installed when the garage was built in about 1994 and it has warped the vinyl siding on outside of the wall it is against.. it has gotten that hot many, many times.. hmm.. quite risky... only have a panel of concrete board on the wall behind it. and thats really all... and it has stainless double wall exhaust flu/vent piping across and out the end wall of the garage and up two stories way high. but the property insurance guy keeps insuring the place though,, lol
have overheated it many many times over the decades,, and warped the inside ceiling of the furnace to where its dropping downi now, but so far havent burnt the shop down... hmm.. and i had nothing to do with the installation of this furnace, and i have never actually installed one either.. yet. but i plan on intalling one over here in my own place when i get my hanbds on a furnace or stove hopefulllly soon hmm.. i know where one actually is right now for cheap a block away form here like dirt cheap like 200 bucks think..... hmm.. and it is an actual double blower large full-blown wood furnace, i really should and need to jump on it asap... hmm.. and wow tht stainless double wall flu vent piping is not cheap at all! that stuff is a pretty penny!! it was at least a 100 bucks a section/piece, like at least ten years ago now :O had to replace it outside because the plain black tin stuff was rusting and bleeding/staining the vinyl siding horribly badly..
