I am in the process of upgrading from a home made OWB to a Portage and Main Ultimizer BL34-44. My existing boiler sits in a 12 x 12 shed with a concrete slab that I installed 10 years ago. I got tired of the leaks and wood consumption, hence the upgrade. The problem is the new 2800 lb boiler will not fit in the shed. My plan is to poor a slab next to the shed run my plumbing straight out the wall to the new boiler. I was thinking of putting a roof over it right away and frame it in and insulate the building over time. IS insulating the building overkill? Do I need to even frame it in? Just seems to me the less exposure to the elements the better, even if it is a self contained unit. IS there anyone that has experience with this unit or can speak upon burning a mixed bag of wood, i.e. pine, larch, fir, cottonwood, spruce??? Our forest is diverse and I have about 90 acres of it. Some dead mostly green.
Thanks for any input you may have, I am new to the ultimizer, but have been running a OWB unit for 10 years so give it to me straight!
