Space furnaces are pretty dangerous.
I believe that some people have to use space heaters, however if you can avoid having to use a space heater, I would absolutely recommend avoiding the space heater, space furnaces do not have to be very dangerous, and obviously, a space oil furnace is more dangerous than a furnace or other traditional heating system, however that does not mean that the space oil furnace itself is scary.
Space furnaces come with a lot of directions that teach people how to use the space oil furnace officially, plus if people would follow the directions that came with the space heaters, they would very never have an issue with the space heater, however unfortunately, that will never happen because people never follow the directions. The way that people use space furnaces makes the space furnaces so dangerous. For instance, did you believe that you are not supposed to use a space oil furnace for an extended period of time? Space furnaces draw a lot of power plus can cause an outlet to melt if not turned off, and people also should never leave a space oil furnace on while in the night or when they are away from home. Unfortunately, people often use space furnaces to consistently supplement heat, which means that people hardly ever turn their space oil furnace off. This is a immense fire risk! Furthermore, space furnaces are often put in spaces that are unsafe for the space oil furnace because people do not pay attention to it. The space oil furnace may not be dangerous in itself, however they are when you give them to people.
