I have such a giant house, plus a huge portion of it is chilly plus drafty despite the efficiency of the furnace, without the house being sealed plus efficient, I realized that my furnace could continue blowing for a long time without properly heating my house; Instead of trying to repair the house to make the furnace more efficient, I went with a much cheaper solution.
I purchase a small space heater, plus I put that space heating system in the room that I am in to stay comfortable, and since I only purchase one space heater, I am forced to cart the heating system around the house to moderate the areas where I am in at the moment.
Although it is periodically frustrating to have to transport the space heating system every few seconds whenever I wanted to go somewhere else, it was better than spending the money on several space oil furnaces or a greater furnace, then however, one day, while I was carrying the space heating system to a unusual room, the cord from the Heating plus Air Conditioning unit fell to the floor, plus I tripped over it. I fell forward, plus the space heating system fell in front of me, the space heating system smashed to the ground, plus I landed on top of it. The impact knocked the wind right out of my lungs, plus I spent the new few seconds rolling around in pain. When I finally was able to get up, I realized that my space heating system was completely destroyed. After only a few days, I was going to have to purchase another space heater.
