Mulch pile at my mill heating up

[Sawyerfortyish]

We were discussing the same thing our pile was at 204 deg. The water temp in our outdoor wood furnace stays around 190. On a pile this large you could heat a house. It would be a pain to pull a coil out of the mulch without damaging it when you go to sell the mulch tho

I have been piling up bark for several years but have never seen steam rising from it. It is mostly pine bark that is easily peeled off of the logs plus some hemlock bark. The pile has become affordable housing for some critter.

Growing up in Northern Michigan I had a buddy with a big sawmill. He laid and welded a couple hundred feet of used scrap gasline (18-24") and then built his sawdust pile over it. He had a barn fan at the outboard end and blew air into his mill building in the winter. The heated air coming into the building was almost too hot to hold your hand in front of.
