What can be done to help reduce fuel consumption in an oil furnace?

Implementing proper insulation in a home is a highly effective way to reduce fuel consumption in an oil furnace. Insulation helps to maintain the desired temperature within the living space by minimizing heat loss during colder months. When a home is well-insulated, the furnace does not need to work as hard to maintain warmth, which ultimately leads to a decrease in the amount of fuel it consumes.

By preventing heat transfer through walls, ceilings, and floors, proper insulation ensures that the heated air produced by the oil furnace remains in the house longer. This efficiency means that the furnace operates less frequently, further contributing to reduced fuel usage over time.

Addressing other aspects such as lowering the thermostat setting may result in less fuel consumption, but it can also lead to discomfort if the home does not reach a desirable temperature. Increasing airflow can improve the efficiency of the combustion process but may not directly impact overall fuel efficiency. Running the furnace more frequently would likely increase fuel consumption rather than decrease it, as it operates more often to maintain the desired temperature.
