A comparison of two #sauna #kiuas (stoves). Heating up in winter conditions (around 0C or just under) in an outdoor timber building. After initial small load to get going:
* Old #Harvia Pro 36. During third load would hit 50C (still burning). Fill it up, head indoors to get drinks, undress etc and about 60C to start sauna
* #Muko #Veto 2 (small Helsinki company with lot of history). Reached 55C during first load (still burning). Fill it up, indoors. Back at the sauna and it's >80C
