A while back when home heating oil was well over four dollars a gallon and my income was not I was looking around for a cheaper heat source. Turned out kerosene was about a buck fifty less a gallon and a heater would do a good job of heating up our living and dining rooms, so at least some of the house would be warm. One gallon lasted about 10 hours. At night when everyone went to bed I would turn the thermostat down to conserve on fuel oil so of course in the morning the house was cold. I would turn up the heat in the morning and turn on the kerosene heater. From this a new tradition was born, my children would sit on the floor in front of the heater and eat their breakfast, warmest spot in the house. Now since heating oil has declined and my income increased the heater is collecting dust in the basement. But it did save me money and served its purpose.
