How Oil Heating Works
There are two different types of oil heating systems: air-based and water-based. Water-based systems can be further divided into standard hot water systems or steam systems.
Hot Water Oil Heating System
If you have radiators, you have a hot water heater system — either a standard hot water system or a steam system. The burning oil is used to heat up water, which then circulates through the radiators to provide heat throughout the house.
Hot Steam Oil Heating System
If you have a boiler, you have a steam oil heating system. This heating system is also water-based, but your oil is used as fuel to boil the water into steam, which then passes through pipes and heats the home through your radiators.
Warm Air Oil Heating System
An air heating system works a little differently, with a hot air furnace. In this type of oil heating system, your oil fuels the heating of air in the furnace rather than water. It works in concert with a blower to force that heated air through the ducts and out of the vents of your home.
Where Does the Oil Come In?
By now, you may have a better understanding of whether you have a boiler or a furnace. But where exactly does the oil part fit in? Good question. Your oil heating system has what is called a combustion chamber. The system pumps oil from your tank into the chamber, usually through a process called pressure injection.
What Is an Oil Furnace?
An oil furnace is one type of system you can use to heat your home. Oil furnaces are large machines that require a separate space. Many homeowners will find oil furnaces in a storage room, closet, or basement for security and safety reasons.
The Process
An oil furnace works in a simple and powerful way to heat your home. But remember, these complex machines do a lot of work to keep you comfortable.

How does an oil furnace start?
The heating cycle for an oil-fired furnace begins when the thermostat senses a drop in the temperature and the need to generate heat. This causes the activation of the burner motor that pulls heating oil from a storage tank.
How does oil break up in a furnace?
The oil breaks up and vaporizes as it passes through a nozzle, which enables it to be ignited by the spark. After a brief delay to allow the heat exchanger to warm up, the furnace’s blower motor draws in air that is heated as it passes over the heat exchanger.
How does a furnace start?
Your furnace starts when it receives a signal from the thermostat that tells it to turn on. Depending on the temperature you set, when the thermostat detects the air temperature dropping below that number, it activates the furnace.
What is a furnace system?
The most common type of furnace is a gas-powered central air system, which heats air in a one area and then distributes it throughout the home via ductwork and vents. This system is also known as a ducted warm-air or forced warm-air distribution system.
How does a heat exchanger work?
As the heat circulates through the heat exchanger, the blower motor and fan moves the heat through plenum, and from there through the rest of the ductwork in your home. The heat flows through the various vents in your home to provide you with heat. Once enough heat is generated, the thermostat will shut off the heater.
What happens when the thermostat detects the air temperature dropping below the number?
Depending on the temperature you set, when the thermostat detects the air temperature dropping below that number, it activates the furnace. When the thermostat sends its signal to the furnace, the furnace gas valve opens and ignites the burner component beneath the combustion chamber.
How does a gas valve work?
The gas valve works with the thermostat to regulate the amount of gas that flows into your furnace. If your gas valve is working fine, but the furnace isn’t turning on, check to make sure your pilot light is on.
What is a thermocouple?
Your thermocouple is an essential safety device that makes sure your gas valve is not sending gas into a furnace without a working pilot light. The flames from the burner component heat a metal heat exchanger. The heat circulates through the looped tubes of the heat exchanger, transferring the heat to air.
What are the main parts of a furnace?
The main parts of your furnace are the control system (thermostat and electrical controls), gas valve, burners, heat exchanger, blower, and duct and ventilation system. When your furnace creates heat, combustion gases are vented out of your home via a flue pipe. Thermostat and Gas Valve.
How does oil burn in a furnace?
