What is the typical voltage for an oil-fired furnace?

The typical voltage for an oil-fired furnace is 115 volts. This standard voltage level is commonly used in residential heating systems, including oil burners, as it is consistent with general household electrical systems. An oil-fired furnace generally operates on standard electrical current to power various components such as the ignition system and draft motor, ensuring proper combustion and efficient operation of the heating system.

Using 115 volts is advantageous as it accommodates a wide range of operating equipment without requiring special wiring or higher voltage circuits, which smooths installation processes and allows for greater compatibility with existing electrical infrastructure in most homes.

In this context, other voltage options would not be suitable for oil-fired furnace operation. For instance, 240 volts is typically used for larger appliances and may exceed the requirements of a standard residential oil burner. Similarly, lower voltages like 48 volts and 12 volts are generally unsuitable for this type of furnace, as they do not provide sufficient power for the required operations.
