Thanks, Yanche, but I'm in Maine. (Just added that to my profile.)
My problem is compounded by the need for a direct or power vent stove, and I prefer direct. I could direct vent the oil boiler and free up the chimney, but that would entail major work and re-plumbing in the basement. I considered switching out the burner in the boiler and going with natural gas. Code requirement for a stainless liner eats away at the savings, but worse, code requires me to remove my 2 new oil tanks if they aren't in use. I don't really want to do that, since gas has been more expensive than oil in the past. If I could retain the tanks and have the option of switching back and forth, I'd go that route. Were my boiler and tanks not new, I'd consider putting in a new boiler.
The best, simplest solution for me was a DVC500 in the living space.
I am left to wrestle with this question: If I can't get one until February, would I be better off saving the $4500 I was planning to spend on stove and coal to pay for oil, then order a stove early next year?
One ray of hope for me... the dealer in Millinocket signed up with Harman for a sort-of showroom stocking deal where they promise to take delivery of a certain number of stoves through the fall and winter. Several DVC500's are in the plan. And, my name is first on the list to walk in and plunk down cash for one. However, since Harman is so slammed, the dealer fears they will not get those units. They said Harman isn't accepting any stock orders, only orders pledged to customers. And, they claim, Harman has not been very forthcoming about whether or not they will fill this previous stock plan order.
One lesson learned. When building a home, have multiple chimneys and/or flues. More flues give you more heating options.
