Wife and I recently purchased an 1878 farmhouse. Original house is 2000 sf two story and a 700 sf "L" shaped addition has been added consisting of a 450 sf kitchen with 16 ft ceilings and a 250 sf hexagon room with lots of windows. Looking for a stove to supplement the geothermal unit that does well in the original home but the addition seems to be an efficiency nightmare due to the number of windows. We had regular $750 electricity bills last year. The stove will be in the kitchen on the shared wall with the hexagon room so it's not directly underneath the bedrooms. I like the idea of temp control with the cat stove (low and slow). My question is will the Cape Cod be too much since we spend most of our time in the hexagon room? Other suggestions?
