hi, I am trying to heat a 12x9 mudroom that is tiled with slate flooring over a slab of concrete, sliding glass door and 2 windows. There is no heat source now. The floor and room gets very cold and I am trying to convert this area into a breakfast nook. When I leave the inside door to the room open, the temp gets to about 62 with still a very cold floor. I had several people give me opinions: add a heating duct, add a ventless fireplace, add heated tiles plus a heat source, use linoleum to warm up the floor. I am trying to get the room to about 70 degrees but am not sure what will work with so many opinions. Any opinions on Bobvilla.com?

An answer could depend on what type of heat you have in the rest of the house. Electric radiant panels are the simplest method.

The house is heated by a gas furnace, additional ducting could be difficult or ineffective.

Consider a direct-vent gas wall heater.
