I have my new piano in a room with a wood-burning stove. The stove is not in line of sight with the piano and I have a ceiling fan to circulate the room's air. For the concerns about heat from the stove I'm not sure how this is any different than my baseboard heater (the alternate heating source, also across the room) or forced air heating. I don't keep the room heated all the time which I realize would be best for the piano but I can't afford it, I only heat when I'm using the room. Winter temperatures in the room are usually at mid-50s (unheated) and this rises to around 70 the few days/week I heat. Winters are short here, only a few months of any heating each year.
I live at the coast so the humidity tends toward too high (usually in the mid-50s to low 60s) rather than too low and using the woodstove doesn't seem to have much impact on the hygrometer readings.
The other concern I have is increased particulates in the room from the stove. I mitigate by keeping the piano closed most of the time the stove is operating.
All this may shorten the life of the piano, but it is what it is! I think a piano is ultimately a depreciating consumable, like a car, sadly. It'd be best for your car to leave it in the garage all the time, never take it on any bumpy roads, but sometimes that's what you want to use it for!
