I finally finished the replacment of my central boiler with a Profab Empyre Pro 200 Outdoor Furnace on Sunday. After some small test runs for leaks and triple checking connections, i loaded the small ( as compared to a small Central Boiler) firebox about 3/4 full last night. I expected it to be empty this morning but it was still half full! Its mild now but it still was 22 degreee F last night. Its much steadier in maintaining consistant temperature also, where my old Central Boiler Classci was up and down up and down..
While some might see the engineering as low tech because profab uses firebrick and fans that can be purchased off the shelf, I think that is a great thing because I can repair it myself if a fan goes bad or a firebrick gets broken. The whole secondary burn chamber is made from conventional firebrick with a few special cuts here and there. I tell ya, when you open the small secondary burn chamber door its like a blow torch blowing out.
I put temperature gauges on the supply and return and it turns out my line losses are pretty low, when there is no demand from the house the two gauges are two or three degrees apart and I still have six feet of soon to be insulated bare pex exposed to the elements. I know this is prolly not the best accuracy wise as the return tempature gauge housing is probably picking up heat from the boiler itself but the supply side guage is getting the same thing.
any how, at this point, i highly recommend the Empyre Pro Series gassers..
