Hi Guys,
I'm in the process of building a 60'x60'x17' garage/workshop and am going to partition off a 11'x13' room in one corner to house an EKO 40 boiler. I'm going to use 8" stainless Metalbestos and either go straight up, or may go thru a wall thimble and strap it on the sidewall and run up thru the overhang. ( I tend to like that option a bit better as I don't have to go thru the floor of the mezannine or insulated attic ).
According to the EKO info, they want 36" clearance on the rear and 18" on both sides. I'd like to crowd the boiler tighter to the corner of the room than that.
Does anyone here have experience in how hot it is in those areas? I'd like to be about 18" rear and 6" sides. In looking at the boiler, I can't see how there would be any significant temps radiating off those areas, other than the flue pipe itself - and that temp at the wall will be the same regardless if it were 12" or 12 feet.
I could stand off a second layer of metal wall sheeting a couple inches as a radiation shield ( 1" gap from floor, open on top ) from the regular wall ( 2x8 stud, R25 fiberglass insulation, metal pole barn sheeting inside and out). I would be startled if temps behind a radiation shield would get much above ambient ).
Also I can get a black EPDM boot for the roof that is rated 212*/275* contunuous/intermittant. There is an ugly orange silicone one available rated at 437*/500*+ also, but the black matches the roof better. Any guess on whether the skin temp of that dual-wall Metalbestos at 20 feet in the air would ever exceed 212*? In my current boiler (Buderus) the single wall stainless flue can be nearly glowing hot but the skin of the dual wall is probably less than 200*.
