Understanding Oil Furnaces

 
An oil furnace is a type of heating system that uses oil as its fuel source to generate heat for your home. It works by burning oil to heat air or water, which is then distributed throughout the home via ducts or pipes, providing warmth during colder months. In this guide, we’ll walk through what is an oil furnace, how does an oil furnace work, the benefits of using an oil furnace, and how to choose an oil furnace for your home.

What is an Oil Furnace?

An oil furnace is a heating system that uses oil as its primary fuel source to warm residential spaces. It includes several key components: a fuel tank, burner, heat exchanger, and blower. The burner ignites the oil, producing hot gases that pass through the heat exchanger. This heat is then transferred to the air circulated throughout the home by the blower.
 
Oil heating systems date back to the early 20th century as alternatives to coal and wood-burning systems. The introduction of oil-fired heating systems revolutionized home heating with improved efficiency and convenience. Technological advancements over the years have led to more efficient and environmentally friendly oil burning furnaces, making them a reliable choice for homeowners.
 

How Does an Oil Furnace Work?

An oil furnace operates through a combustion process that efficiently converts fuel oil into heat energy. The process starts when oil is stored in the furnace's tank. When the thermostat signals a drop in temperature, the burner ignites the oil, creating a flame that heats the air. This heated air is then circulated throughout the home via ducts, ensuring a consistent temperature.
 
Key components include the burner, heat exchanger, and fan. The burner atomizes the oil and mixes it with air for combustion. The heat exchanger captures the heat from the burning oil and transfers it to the air, which is then distributed by the fan through the ductwork.
 
Safety features are crucial in oil burning furnaces. Modern units come with automatic shut-off valves, flame sensors, and safety switches that deactivate the furnace if a malfunction occurs. Regular maintenance is essential; homeowners should schedule annual inspections to check for leaks, clean filters, and ensure all components function correctly. Regular upkeep enhances efficiency and extends the lifespan of the furnace.

Benefits of Using an Oil Furnace

Oil furnaces offer several advantages, making them popular for residential heating. 

Energy Efficiency

One primary benefit is their energy efficiency and performance. Modern oil burning furnaces have high-efficiency ratings, converting a significant portion of the fuel into heat. This efficiency ensures consistent warmth and contributes to lower energy bills.

Cost-Effectiveness

Cost-effectiveness is another advantage. Although the initial installation may be higher than some other heating systems, the overall savings on heating costs can be substantial. Oil prices are often more stable compared to natural gas, and with regular maintenance, an oil furnace can provide years of reliable service without frequent replacements.

Fuel Availability

The reliability and availability of oil fuel add to the appeal of oil furnaces. Unlike natural gas, which requires a gas line connection, oil can be stored in a tank on your property, making it more accessible in rural areas where natural gas infrastructure may not be present. This offers flexibility for homeowners without relying on an external gas supply. 
 

Six Factors To Consider When Choosing An Oil Furnace

Several factors should be considered when selecting an oil furnace. First, assess your heating needs by evaluating the size of your living space, insulation quality, and local climate. An undersized oil burning furnace will struggle to heat your home, while an oversized one may operate inefficiently and increase energy costs.

1. Heating Capacity (BTUs)

The heating capacity of a furnace is measured in BTUs (British Thermal Units). It’s essential to choose an oil furnace with the appropriate BTU output for your home size and insulation. A unit that’s too small will struggle to heat your home, while one that’s too large may lead to inefficiency and higher energy costs. A professional HVAC technician can perform a load calculation to determine the proper size for your home.

2. Efficiency Rating

Oil furnaces come with varying levels of energy efficiency, typically indicated by the AFUE (Annual Fuel Utilization Efficiency) rating. A higher AFUE rating means the furnace converts a higher percentage of fuel into usable heat, resulting in lower heating costs. Look for a furnace with an AFUE rating of at least 80-90% for better energy efficiency and reduced fuel consumption.

3. Fuel Storage and Availability

Since oil furnaces rely on oil as a fuel source, it’s important to consider the availability and storage capacity of heating oil in your area. Ensure that your home has a suitable oil tank that can store enough fuel to last through the winter. You’ll also want to evaluate delivery schedules and costs associated with refilling your tank.

4. Size and Space

The size and design of the oil furnace should fit your available space. Depending on the model, oil furnaces can be compact or take up more room. Be sure to choose a furnace that fits comfortably in your home without compromising airflow or causing operational issues.

5. Maintenance Requirements

Regular furnace maintenance is crucial to the efficiency and longevity of an oil furnace. Some units are easier to maintain than others, so consider the furnace’s ease of serviceability. 

6. Noise Level

Consider the noise level of the furnace if your home has living spaces near the furnace or if you’re sensitive to sound. Newer models tend to be quieter, so choosing one with sound-reducing features may improve comfort.
 

The Importance of Professional Oil Furnace Maintenance 

Regular maintenance is essential for the longevity of your oil furnace. Schedule annual inspections with your local Bryant dealer to check for wear and tear, clean the system, and replace the oil filter. Keep the area around the furnace clear of debris and ensure vents are unobstructed for efficient airflow.
 
Be alert to signs that your oil burning furnace may need servicing. Unusual noises, inconsistent heat, a burning smell, or increased heating bills could indicate a problem. Consult your local Bryant dealer for a thorough inspection if you notice any of these issues.
 

DIY Oil Furnace Maintenance

There are a few maintenance tasks you can handle yourself to keep your oil furnace in tip-top shape:
  • To operate your oil furnace efficiently, set your thermostat to a comfortable yet economical temperature. 
  • Regularly check and clean furnace filters to maintain optimal airflow and efficiency. 
  • Monitor your oil levels to prevent inefficiency and potential damage from running low on fuel.
