Inspected a home that was approximately 800 sq ft. 90+ years old, but remodeled interior. 2 bed 1 bath, kitchen, living room, laundry room. The only heat source is a free standing gas stove in the family room. Kitchen is in a different location from the family room as is the bathroom and laundry room. Both bedrooms don't have a heat source. Is that a sufficient source of heat for that many rooms?
