larson, i dont see any weld marks on your door but i am hoping that you have the door lined with firebrick of some sort. If your door is just a piece of plate I don't think it will take the heat and will warp

I think from your photos that i see a nice wide frame inside the stove where the door is so it looks as though you have made provisions for an insulated door, i am not being critical of your stove at all. i am just pointing this potential problem area if you have missed it.

Your photos did not show the door (unless I missed it)

good luck and it's nice to see more folks building their own.

willie, on the other side of the door there is a 5/16 plate that comes out 4 inches and is beefed with angle iron, between the plate and the door i will put some sort of insulation to.

larson. good idea....i used 3x3 x5/16 angle around the door frame and 2 pieces back to back up the middle and filled in with fire brick with a piece of wire mesh over top to hold them in. the door gets warm to the touch but not hot enough to burn skin

looks good ..is the back of the firebox in water? or just the sides  where are the water line hook ups,only could see in rear on a pic,  did you weld in bungs for other things like water level site, temp gauge ,future aux lines.how much insulation can you put round it?

rosewood, the back of the firebox is not in water, this boiler is going to be under 10psi so it will alaways b full of water, there are 3 couplings for the main lines on top of the stove in the back and 3 couplings that return the water to the front bottom of the stove. I think im using 2 out of the 3 available. There is a press./temp guage in the front and a temp/relief valve and a honeywell aquastat in the back that will run the solenoid and blower. As far as insulation goes the sides will have 6" at one point b/c it is round but as it continues to round there will be more, and the back has room for 16" and the roof 20", plus there will be 3/4" foil faced foam sheeting which is r5 that will go on the outside of the cage before the metal roofing goes on.

thanks scott, well im finally heating my addition without insulation so a total of 2200 sq ft and i can still get 20 hrs between fills. i have infloor heat and when i went to turn on the floor in the addition it froze so it took about two weeks of heating it with an old cast iron radiator before it let loose, doin good tho i just need to get it insulated so i can save some wood.
