In cold cottage a plate is so leaning on the wall (not yet fixed) next to a corner of the table that we are sitting in a corner, irradiated while eating her. That's a warmth like a fireplace and after a few minutes effect. The infrared radiation heats eg auchdie chair backs, so that indirect heating is carried out. The second plate is placed on the sofa only to the pillow top, until the winter is over. Here especially the head is heated: also an important part of the body. For rooms with no heating period an ideal complement.
