Well, I don't have any experience heating a stone castle, but when we lived near Diamond Lake (in the Cascade Mountains of the Pacific Northwest) we heated a 3 bedroom house with only one wood fired stove. There were still snow patches around in August!! The only way to be reasonably comfortable was to NEVER let the fire go completely out and wear lots of layers.
If we did have occasion to leave for more than a day or so, the core of the house would be so cold that it would take a week or more to warm back up. The metal of the stove would radiate for about half a day, but more than that and you were sunk.
