That makes me laugh; folks here in the US often say that heat pumps don't work below 0 C 🤣
In the end, during shoulder season you can run the heat pump too, so I don't think you can go bad either way.
If you do one stove AND it's in a place where you spend a lot of time (do ambiance matters ), get the PE if you care about flame.
If it's in a place where you don't spend a lot of time, I'd get the BK.
Just for comparison, I'm heating 1700 sq ft 1978 building, plus 825 sq ft basement, walls mediocre insulation, attic air sealed and R57, with a BK.
I Had a 22 hr run on a 85% full fire box of red oak, with outside temps varying between 36 F minimum and ,the max at 46 F (,1 hr only). The living floor above the basement was 71.5 F all the time. The bedrooms above that were 5 F cooler.
There is. no other stove I know that can do that. But there were no flames for 75% of the time.
No idea how this example compares to your need for heat.
