First thought is, Yes, that should be enough heat for a 1400sq ft cabin. 1800 in Alaska is probably too big at your low temp. But you have a ton of variables in log cabin construction. Logs shrink and move. You won’t have even insulation. Home placement is a huge consideration as far as sun exposure and wind exposure can change heating requirements . I think a second stove is wise if it can be installed in a safe place. Depending on floor plan, emergency exiting, etc, a safe place may not exist.For a 1,450 to 1,850 square foot cabin with 2 floors and 3 bedrooms is one centralized Blaze King King 40 wood stove plenty sufficient for to keep the cabin warm or should there be a smaller wood stove installed on the 2nd floor?
For a utility shed that is used to house the backup diesel generator should I have installed in there a smaller wood stove or a non-electric Liberator Rocket Heater Generation 2 Pellet Stove with Hopper in case the generator needs to be warmed up?
Same question for a basement and garage? I'm trying to figure out if all it takes is one giant wood stove or if you should also add in smaller wood stoves or a non-electric gravity fed pellet stove.
Wood stoves in garages are frowned upon by code and insurance companies.
How many different wood stoves are you thinking about trying to run at once now? Are there locals up in the area of Alaska you’re looking into that you can talk to to find out exactly what is needed?
Can you rent a place up there for a year?
