Daka forced air furnace, finished install

[ikessky]

Finally finished the duct work for my Daka forced air furnace. I still have some work to do in the room itself (lighting and what not), but at least the heat is moving into the ducts. I'm still trying to decide if I should wrap the 8" ducts and the first few feet of the rectangle ducts since those will be the warmest. Or maybe I'll just need to buy the extra blower and get the air moving faster.

I ran a wood add on furnace for about 17 years. Insulating the duct work will help but your living area comfort zone will benefit more from increased air flow. The electric bill will see a small increase obviously but the trade off will negate the increase compared to the boost that might be needed by your fossil fuel heat source in severe winter conditions. The blower is the best option followed by the added insulation. In my application in hard winter weather the blower would run constantly but lacked the cfm to keep the house warm and the oil furnace would have to periodically kick in...Cave2k

do you have the pipe turned at at 90 where it is in the pipe?

Sorry henfruit, your question is confusing me. Are you referring to where it enters the existing duct work? I basically cut holes in the existing duct work and used starter collars to attach the 90 degree bends to.

It's currently 73 degrees in here, which is a little warm for my taste. I have one duct run that is currently closed at the register inside the house. I will be removing it from the house and sending it to the garage. That will help bleed a little of the heat from the house so that it doesn't get so warm. Plus, the dog and cat will appreciate the heat for the garage!

HI. iwas wondering do you have it set up so that the air from the wood furnance is blowing down the length of the duct work as oppposed to just to just into it? i had a set up like yours and i used a 90 into the duct work to send down the line.

Not blowing down the line, just into the duct work. My house is fairly small so the duct runs aren't all that long. The wood furnace is also fairly centrally located, so the distribution has been OK so far. The fan for the wood furnace comes on when the air jacket reaches 110 degrees and shuts off at 90, so it is basically giving a constant stream of warm air through the duct work. It typically only shuts off when the coals have died out.
