The photo shows this as a very open space. Massive radiant heat off the glass of the stove will heat the objects in the room in front of the stove. Those objects reflect and re-radiate that heat to warm the air. Convection moves the air around. You will get plenty of heat in the space behind the stove. If you look around this site, you'll see countless references to the way wood heat "feels better" than other types of heat. I've theorized that this is because we enjoy moving from cool to hot, or standing in a cooler space while feeling a searing heat on our skin. Think hanging around a campfire on a cool summer night. With a wood stove, you end up creating this scenario. You can run the thing to where your entire house is above 80F (many here do), but I typically keep the house at or below 70F. I enjoy sitting down in front of the stove, and feeling the radiant heat off the glass warm my face and feet. It's a satisfying sort of heat, which you never get from a central system.
