I literally cannot guess that my parents still do not have a furnace.
The way that they heat their house is harshly unsafe & dangerous, & they have been doing it for nearly 6 years. There have even been a few times when my mother almost burned the house down because of the way in which they heat their house… My parents have consistently dreamed of owning a house, but their credit is terrible, & the only way that they are going to be able to own the house is by doing a rent-to-own contract on a house in bad condition. Sure, they found a house that was within their budget, but the house literally had no appliances, including no furnace. Sure, there were other concerns, but they live in the North, & having a furnace is a pretty major deal in the North, but you could literally die in your house without a furnace, & they didn’t have a furnace. They knew that they weren’t going to be able to afford a furnace, so they began buying weird types of space gas furnaces that run on weird types of fuels. Already, you entirely suppose that space gas furnaces are not nearly as safe as a furnace. However, it is much worse than that. My parents could not afford a modern space heater, so they purchased aged & used space gas furnaces for their house. There were numerous times where they almost died because they almost burned their house down with these space heaters. It has been years, & they are satisfied with not owning a furnace. I have no plan how they do it. I would never want to live without a normal furnace.
