We did a log home this past week, waiting for the contractor's bid to come in. It isn't a log cabin as it is huge.
Can the fireplace be the only source of heat for my new home in the mountains?
The Guideline actually states the heating system must be capable of maintaining 70 degree's at 36" off the floor and be thermostatically controlled. Can you meet that criteria with a fireplace?
Maybe, if it is a gas fired fireplace, possibly free standing that you can adapt a thermostat to you might be in business. We have see this happen in a few homes over the years. The kitchen will likely put out heat into the home when cooking and washing as well but the gas fired fireplace with a thermostat should be sufficient in many cases.
