I currently use oil to heat my home and gas for hot water, is there anyway to convert to a dual system which would still work during outages
also my back extension, a 22 foot by 12 foot room which has gas running to an indoor grill which we don't use. below the room is a 4 foot crawl space. the room is always freezing in the cold winter is usually 40 to 45 degrees. could we have a separate gas burner for this area , which could then be a back up area of warmth during power outages? what is the cost? I do have a fire place in this room with a short chimney that does go to the one story roof in this area.
