You should really consider a wood furnace over a stove. Not the outdoor furnace, but the inside furnace with blower/s. Although an investment in the beginning, they pay for themselves quickly and last. I have one that's been used for 15yrs and I replaced one single brick. The blower will circulate air. Its not necessary to run a lot of heat pipe, only to the immediate work area. Even just 90 degree attachment to direct the heat works.
