I am in the planning stages of building a one room log cabin that will be located in the New England area. I will actually be living in it year round. I have a normal electric heating system, but it is not uncommon to lose power for days or even weeks at a time. Because if this I have been looking at pellet stoves with a battery backup or possibly a wood stove. I have two questions. This cabin will be 400 sq ft with 13 ft vaulted ceiling. Which would be better for occasional use and what size stove. If it helps I am a retired old lady so lugging logs might be an issue. Any recommendations?
