My heat in my addition went out this past fall. The plumbers in the area were overwhelmed with all the flooded basements this year. The guy that has worked on it said he couldn't get to it until January. Well, January came, and he didn't.
I went with electric heaters and use a small propane one to heat rooms and give the electric heaters a rest. During the cold and windy spell, the electric heaters only heated rooms to the mid 50s. The propane would bring it up into the 60s within a half hour.
You can use propane, but you can't bring the tanks in the house. If you plan to use a 20lb tank, you'll need to get a hose extension and bring it through a window or some other method.
Or, you can use 1 lb tanks that are disposable. You aren't supposed to fill them, and if you have a fire or some other disaster, you probably won't be covered by insurance, and there is a penalty of up to a $500,000 fine and 5 years in jail. They do make reusable 1 lb tanks that you can refill. Flame King makes a kit for about $50-60. Makes things affordable.
If you go with a bigger tank on the outside, Tractor Supply had some gas heaters with a thermostat and fan for $149. I almost bought one. But, you aren't supposed to use any of the gas heaters while you are asleep. You might not wake up.
I have a wood stove in the main house, so I keep my oil heat temp down and use the wood to take the chill off. In the bedroom, we have a mattress pad heater that makes a cool room tolerable. Bathroom trips are a little spirited.
I never used kerosene as a heater. I've been in places that had them and they smell worse than gas.
