Scott and I have been back in Torrey for one week now. However Scott completed a big project here while I was wrapping up loose ends in Logan. He built the adobe wall behind our masonry stove. Our thinking is that our masonry stove will heat our big main room and, at the same time, heat the adobe wall. The warm wall will then heat the air in Scott's office on the other side.
The mortar recipe was essentially the same mix used in the plaster on the exterior of the house - high-clay-content dirt from our property, a little added masonry sand, finely chopped straw and water.
