I have a very limited basement area, 14 x 16 and only 7.5 tall. I can't knock out any walls to get big tanks in there because they are all load bearing with many things causing interference.
CT is Nazi like with OWB's. My town building inspector absolutely refused to wrap his hands around the idea of an indoor gasser installed in an outbuilding next to or attached to the outside the house. All he could understand is the OWB concept, which would have required a 4th flue approaching 45 feet high to clear the neighbor's roof peak. When I discussed a Garn Jr installed inside of a shed / alcove addition to the house on a concrete slab, all he could understand is "you can't direct vent an OWB, you can't put and OWB next to or attached to the house, you can't put a wood burner in a garage." The guy was soooo close minded.
When it is all said and done I should have:
- 400 gal of thermal volume with an ok boiler, that is simple enough for my other half to operate.
- be way better off than with a stove or hot air furnace.
- come in at 1/4 the cost of a full blown Froling 20/30 system with 400-800 gal.
- come in at 1/3 the cost of a Garn Jr.
Is it a risk? Yes, but I am hoping with the improved design of the refurbished unit, proper plumbing & operation it will serve us well.
Maybe we don't hear about all the ones that work good, only the owners with issues that come to Hearth looking for answers? Heck, even the dealer who I allmost bought a new one from, ran a 1st gen 100 in his pellet warehouse for 2 years with no issues. I could of bought his unit for 500 less, but I chose the refurb unit with stainless liner instead. Why did he have his unit for sale? Not positive but maybe it had something to do with him disolving his business relationship with Pro-Fab. My understanding is that his pellet and hot tub business is just dandy.
