The whole idea of these forums IS to mind other folks business. Otherwise I would make an uneducated decision, and wish I woulda' known the pitfalls BEFORE, but of course, then it's too late. So read, and comment, and be the Devils advocate... No problemo...
The house DOES have a very nicely built fireplace, stone over cement block, with gaps for air circulation aided by a hidden fan. There's also a wood boiler in the basement, next to the oil boiler. Maybe I'd put up with the wood required for the house, but we're buying the place because of the large warehouse, and that's heated by propane, I think, with direct ceiling heaters.
I'll have to buy a few "Modines". Prolly not a hard to find item, as they were made for a Zillion years. I do all my own plumbing, gas and oil installs, electrical, etc. So I can buy any used Junk, and make it work.
I plan to buy a 1000 gallon oil storage tank with a work bench work surface, and fill it during the summer, when oil shops have more oil than they can give away. In the winter, it'll be scarce, much like finding cord wood or wood pellets, or even oil! I will fill out the load chart once we close the deal on the prop, and figure out what space I'll use, what's insulated, what'll be rented, etc. I may have the faom truck spray some uninsulated walls when we do the trench to the house for the buried water lines.
