I basically live in the desert where it almost almost never gets down to freezing temperatures, and it’s usually quite warm (if not downright hot.)Well yall, if you want my advice, don’t buy a house with a chimney that’s been dry walled over. Bunch of garbage chimneys are
Anyhow nobody needs a fireplace in the desert, especially when you have natural gas and electricity both to heat your house.
My house had a chimney made of stucco and wood, with a insulated “heatalator” glass door metal fireplace inside of it, with a fan and wall switch.
Inside the chimney was a double walled steel flue pipe. Also termites. All of that stuff was removed leaving the masonry hearth, surround, and mantel (also all masonry.) I repaired the termite damage and patched the wood where we removed the chimney from the roof, and then put new shingles on the roof.
I reinsulated and finished the exterior wall with some attractive fake Barnwood, and inside the original fireplace opening is filled with waterproof cement board.
I built a 6” tall wooden base out of some heavy lumber. I finished it with oak and birch & put 125 gallon aquarium on it, on the hearth.
I put another 55 gallon aquarium outdoors on a stand and a 30 gallon pump sump below it. I ran pipes through the wall, and along with a big insulated barrel, this takes care of all my filtration for the indoor aquarium.
I also put up the wood trim and paneling above the mantle piece, with the big clock and photographs. From the little decorations, it appears to this photograph was taken at Christmas time.
