great work!
If your stove's fan does the job, great.
I think you would benefit allot with a duct running back to the stoves blower, like you said.

Check out Dallas's thread from earlier this year.

How do you feel about a thermostat controlled hand fired?

Hi Qball,, this idea you wrote: I may add a register in the dining room and use some smaller duct back to the blower on the stove.....will make a huge additional amount of heat for your upstairs..

Right now, with the basement door open for the cool air return, you are using the entire basement as a big cold air return plenum... Unless you want to heat the basement,, this is not very efficient.. Your stove gives off lots of radiant heat, which will keep the basement comfortable..

I'd hook up the register and duct for a dedicated cold air return, and see if you can close the basement stairway door.. I'm betting you will be able to heat the house quite comfortably on less fuel..

Right, a return air duct is the way to go, but i would keep the return duct the same size as the supply air ducts, don't use a smaller duct. It will work betterthat way.
As to the blower hum, make a break in the line and use something other than metal to stop the hum from traveling along the metal ducts all the way to the registers. Or maybe don't have the two fittings your using as a plenum touch the stove, which means you'll have to support them some other way desides attaching them to the stove.

Your install looks very nice, good job.

Update: Well it is in the 20's here right now and 73 in my house. The front room furthest from the stove and registers is about 7 degrees colder. I will probable add the cold air return there. The register furthest from the stove, about 20 feet, is pushing about 170 degree air through it (temp taken right at the register.) I am very pleased with the airflow from the stove's blower. I have the blower running about 1/2 speed.

What type of temps are you reaching in your ducts? Insulation im looking for my setup is max temp rated for 250f. I doubt getting that the duct is reaching that high a temp but better safe than no longer having a home.
