Years ago I was at a skiclub and there was this device that I would like to
find. Basically the inside of the grate that held the burning wood was
hollow. Outside in the room there was a small fan and flex pipe going to the
grate blowing air through it. And on the other side of this grate the hot
air exhausted into the room. Basically it pulled the heat off the grate and
put it into the room & did quite well.

Does anyone know where one of these can be found? Or what its called?

TIA
