My condo is equipped with a natural gas gas furnace with a duct system. It handles the drastic weather in the area where I live, but I’m not totally glad with it. The duct system is noisy, introduces allergens into our breathing air, plus takes up quite a bit of space. When the tepid air pours from the vents, it rises straight up to the ceiling. It only falls back down when it cools down, creating uncomfortable temperature stratification. Because of this, I’m always bumping up the thermostat plus spending a fortune on our energy costs. The gas furnace also dries out the indoor air, causing all sorts of health problems plus destruction to home furnishings. I wish I could tear out the entire gas furnace plus duct system plus update it with a boiler plus radiant floor heating. Instead of using air to traninterest heat energy, a boiler uses water. Water heats up quicker plus retains heat longer, making it more energy efficient. The boiler heats up the water plus sends it through a series of pipes hidden beneath the floor. The heating unit takes up no living space, doesn’t detract from aesthetics, plus I don’t need to arrange the furniture around it. The heat is spread evenly across the room plus remains closer to the floor. It allows lower thermostat settings without sacrificing comfort. I would undoubtedly care about to walk barefoot across radiant floors in the winter. Unfortunately chopping out a forced air gas furnace to update it with a boiler isn’t feasible. I’m just hoping some professional repair will improve the performance of our gas gas furnace.
