OK I'll try it This a a view of both furnaces Right now this is my partially uninsulated garage which I have closed in I will be my living roon 3 walls are insulate need to insulate the ceiling and furnace wall
this is where the ducts that go nowhere and don't really heat anything yet I'm going to ectend them and run them into the house The one big sucker goes to the greenhouse
I have to figure out why I am not seeing a chimney.
Looks like the existing furnace has some double wall pipe starting at the trusses. Being propane it an absolute NO for sharing that pipe between the appliances.
The propane furnace is meant to only heat the green house and "garage". That is why the cold air return is sucking air from the green house, and most of the hot air is directed back into the greenhouse.
The hot blast chimney is not in yet I had bought the black 6" pipe and for the life of me couldn't get it to go together Had my X try and he couldn't do it either finally got some of it together ..... Then when I tried to adjust the angle the dang elbow literally came apart
I was so ticked off I took it back to the store and......they are no longer open on Sunday
Went to Home depot and bought new stuff (which went together perfectly) but the window of opportunity to work outside closed 'cause that storm started back up didn't want to cut a hole for the double wall T and put the rest up in 40 mph blowing sleet and snow I knew I would be rushing and make mistakes
The furnace has a chimney you can see in the 1st,2nd,and last picture the ducts are that insulated ducting
I know thats why the cold air duct is there I need to know - do I run one to the hotblast? if so,should it be the same cold air or use a different room to run the cold air from?
Pull the return or cold air from the area you want to heat. I assume you don't want to heat the greenhouse, so put in a cole air return from the living space you are trying to heat. Then run the hot air ducts to the same spaces, this will create a circulation loop where the return air is reheated, and sent back to the living space.
