Hot air stoker in basement, capture heat to force upstairs

My HOT AIR "furnace"
So I'm new here. Thought I would share how I heat my house with my stoker in the basement. I have a leisure line pioneer. Being new to coal stoves, I wanted to get the heat upstairs without wasting/loosing heat in an old stone basement. After thinking it through, this design has worked great now for 7 years.

1.Made a metal box, corrugated metal surround for stoker
2.On all outer sides of corrugated metal I have R 30 unfaced insulation
3have foil hard foam board covering over r30
4access door( no r 30 on door, juat metal and foam board)
5 back top half access door hinges upwards to fill stove hopper
6 have 2 pipes coming off top where factory stove blows air, blocked off front holes
7 One pipe goes into 8" flex that goes upstairs and splits off into every room of house
8 the other pipe is 6 inch and splits into all downstairs rooms in house except main living room
9 hole with 3rd 6" duct in top of metal box grabs whatever heat wasnt forced by stove fan and is sucked out by simple ducted internal fan to living room
10 a return 6" hole vent allows cold basement air into bottom of box
11coal trol thermo in living room, even temps in every room, extra hole in metal box has a 90 degreeelbow, lets heat ooz out into basement, basement stays about 55 to 60 all winter long. ( no wasted or excessive hot heat stuck in basement)

After thinking it through, this design has worked great now for 7 years.

I get much more excited about a simple, cheap, setup where you have extracted as much as possible from the system than an overcomplex setup that involves a large capital outlay and more maintenance issues that are not often admitted to.

Not quite how I would do it but well done.

WOW you are creative. Are you looking for suggestions or improvements? If not I do not want to offend your setup. I do commend your results, but with my setup I am constantly tweeking things. Because I can
