Should I buy a kerosene heater?

I am planning to move into an old house recently that has no central heat and air and no propane heaters in it. From what I have read online kerosene heater would seem like the better choice for me despite the cons of them. The 2 rooms are about about 180 sq. ft. The other two are like 100 sq. ft. The electric heaters I have bought have not been putting out enough heat and the oil filled radiator I had bought seemed like it did not get hot fast ehough. help please.
