Yes. It helps. We use oil filled radiators at night set on low in the bedrooms., an oil filled radiator in the living room, and a space heater in the bathroom for showers. Then we heat up the house in the morning and afternoon with oil, then turn the heat down, and the space heaters help to maintain the warmth in the house.

The electric bill went to$175 this month , but we only used 1/3 tank of oil.
