No, I really do think it is the stove--its installation location and the house it's in...not getting enough heat upstairs--or even in the basement--when surface temp is nigh on 500. If I had the MPD here I'd have tried that first based on your info, but I had all of the other stuff on hand from previous work or came with the stove.
I had the (badly!) mistaken idea that 'since the factory rates it at 100k BTU/h and my oil furnace is rated similarly, and doesn't run that much (when set at 62
) that it would have a similar heating capacity. Unfortunately this seems not to be the case. I'd guess, steady-state, I'm getting somewhere around 60% of that rating, if I'm lucky, and the stove is down in the basement. Chose to overlook the obvious, that the furnace doesn't heat the basement much, and that 100k is the max rating, which probably only happens when all stars are in alignment.
