If you are using a furnace as your primary source of heat and you have no backup in case your furnace stops working, then you are toying with danger and are making a foolish mistake.
- This is a very bad idea, especially if you have a wife and children.
Furnaces are very finicky machines, and the HVAC industry has made a lot of money repairing and providing parts for you to be able to fix your heating system of choice. I am sure that you are aware that there are furnaces in every city and every street that stop working, and HVAC technicians are constantly busy in the winter keeping these machines running. Furthermore, most heating systems either run completely on electricity, or part of their operation requires electricity. Therefore, if you experience a breakdown in your heating system or a loss of electricity, you are going to be in very serious trouble. When your furnace stops working due to a malfunction, many people purchase electric space heaters to stay warm. However, if your power goes out, you are going to need a different type of heating system. There are many heating systems that run on natural gas or propane without electricity, and there are also wood-burning heating systems that can be used as a backup in case of an emergency. You could also consider purchasing a generator that could keep some lights on along with your heating system. You need to be prepared to heat your house in an emergency. Your family depends on you for their comfort and safety.
