I did everything I could

I need to either add more insulation or get a better gas furnace… The baseboards around my cabin absolutely don’t have enough insulation in them, however during the Winter, I can recognize the cold air leak from them, but my feet and legs get so cold, and also, if I close any of the doors in the house, that room gets icy cold, but i like to have my family room door closed at night. It freaks myself and others out to leave the door open. Having is closed seals in the cold air from the baseboards and shuts out my gas fireplace. I suppose I might need to rip out all the baseboards and re-insulate them, or, I could get rid of my gas heating plan and get radiant floors. The flooring is what is cold anyway. Having a gas furnace right where the concern area is would solve everything. I could install radiant floors in my family room and close my door. The heated air would never rise to the ceiling and be wasted; Radiant floors have no cold spots and don’t even make noise. I suppose I would care about having electric radiant floors stretched all throughout the house. Removing and setting up a modern gas furnace would be quite the expense though. Honestly, it would be cheaper and smarter to get more insulation. The task would actually smell. Removing baseboards and reinsulating is no fun, however but, after all of that was done, the heating plan in the cabin should toil better. I would not be moderate in my family room, but I would not be chilly cold.
