My house is an older one in a honestly chilly climate. A lot of the time, my life isn’t affected by our living conditions. The only other thing would be my laundry habits. I live about 30 minutes from town, plus I don’t have a washing machine or drying machine at home, so periodically, I make the trip into town to do laundry, however most of the day I just clean the clothes by hand at home. I use oil gas furnaces to warm up our house, plus they constantly task honestly well. On top of heating the home, I make use of the oil gas furnaces to dry our clothes inside when it is below freezing outside. One morning, I had just stopped hanging up our laundry over our heater, when it really began spewing dark smoke. Afraid, I unclogged the heating system plus phoned the HVAC company to check out the problem. The HVAC guy told me that by drying our clothes over our oil heater, I was letting in a lot of moisture into the air around our oil heater. The moisture had hurt our heater’s thermal fuse, which is what works with the heating system turns off. With the thermal fuse is hurt, our heating system overheated plus began to burn the oil inside. The burnt oil led to all the black smoke in our home. The HVAC guy also told me that I was lucky to see the smoke when I did. So, an injured thermal fuse can cause fires in oil heaters. I believe this was the better scenario.
