As a heating system expert with extensive knowledge in the field, I'm here to provide you with an in-depth analysis of the energy consumption of oil furnaces. The power usage of an oil furnace can vary significantly based on several factors, including the size of the furnace, the efficiency rating, the age of the unit, and the specific heating requirements of the building it's heating.

Oil furnaces are designed to provide a consistent and reliable source of heat, especially in regions where the temperature can drop significantly during the winter months. They are known for their high energy efficiency, which is measured by the Annual Fuel Utilization Efficiency (AFUE) rating. The AFUE rating indicates how much heat is produced from the fuel consumed during a typical year. Modern oil furnaces can have an AFUE rating of up to 95%, meaning that 95% of the energy from the oil is converted into heat for the home.

The power consumption of an oil furnace is not typically measured in watts, as the primary energy source is oil and not electricity. However, the electrical components of the furnace, such as the fan and control system, do consume electricity. The electrical power requirement for these components is generally quite low compared to the overall energy consumption of the furnace. For example, the blower motor, which is responsible for circulating the heated air, might consume around 500 to 1000 watts, depending on the model and size.

It's important to note that the primary energy consumption of an oil furnace is the oil itself, and the cost of running the furnace is more closely tied to the price of oil rather than the electricity used by its electrical components. The efficiency of the furnace can greatly affect the overall cost of heating a home. A more efficient furnace will consume less oil to produce the same amount of heat, which can result in significant savings over time.

When comparing oil furnaces to electric furnaces or heat pumps, it's clear that the latter typically require a much higher electrical power input. As you mentioned, electric furnaces and heat pumps often need 15,000 watts or more to operate effectively, which can be a significant consideration when thinking about the capacity of a portable generator or the electrical infrastructure of a home.

In contrast, gas or oil-fired heaters, like oil furnaces, use less power for their operation. The power consumption for these types of heaters is typically in the range of 2500 watts or less, which is significantly lower than that of electric heating systems.

In summary, while the electrical components of an oil furnace do consume some power, the primary energy source is oil, and the focus should be on the efficiency of the furnace and the cost of oil. The power consumption of the electrical components is relatively low and should not be the main concern when considering the overall energy usage of an oil furnace.
