I have been researching the different types of furnaces. In South Bend, IN a furnace is probably a smart move for how to heat your home. A furnace can provide whole home heating with the courtesy of ductwork. It can heat the entire house easily and requires yearly maintenance. Most South Bend heating dealerships are familiar with them. So it is a smart move. There are three different types of furnaces. A gas furnace is the most traditional. The gas furnace requires a complicated set up. You need gas hookups and a flue system installed. You need to make sure the device stays clean too. If it gets dirty and overheats, then it can catch on fire. It can also release carbon monoxide if the heat exchanger cracks. So if you aren’t on it with upkeep, you are totally screwed. There is an electric furnace. This furnace is the most efficient, using 100% of what it takes, but it is so expensive to run. Electric is way more pricey than gas. Living in South Bend, IN means that electricity for heating isn’t possible. There are oil furnaces too. These require an on site oil tank. They are large, ugly, and invasive. But the cost of oil is better and the furnace burns a hotter flame. I don’t think I am going to choose this one though. I guess the thought of a gas furnace for my South Bend home is the best option. I am not pleased with my choices though. I might go back through and try to find a different heater.
