New Homeowner Heating Oil Guide: Everything You Need to Know

If you just bought your first home with oil heat, you've inherited a system that millions of Northeast homeowners rely on every winter — and one that requires a little more active management than a natural gas or electric system. You need to order your own fuel, monitor your tank, and find a dealer before the cold hits. Here's everything you need to get set up correctly from the start.

Step 1: Find Your Tank and Check the Level

Your heating oil tank is most likely either in the basement or outside above ground. Most residential tanks are 275 gallons (a common size is roughly the shape of a large bathtub standing on end). The tank has a gauge — typically a small clear plastic tube at the top with a float that rises and falls with the fuel level, marked in fractions (Full, 3/4, 1/2, 1/4, Empty).

Check the gauge now. If you moved in during summer or early fall, the previous owner may have left the tank nearly empty — this is common because oil companies don't typically top off before a sale unless specifically arranged. You want to have oil in the tank before heating season begins (before the weather consistently drops below 50°F at night).

Step 2: Find a Heating Oil Dealer

Unlike natural gas (which is piped to your house by a single utility), heating oil is delivered by private dealers who compete for your business. You need to choose a dealer and set up an account. This is actually an advantage — competition keeps prices lower than a monopoly utility.

How to find a dealer:

• Search "[your town] heating oil delivery" — local dealers will appear
• Ask your new neighbors who they use (local knowledge is valuable)
• Check if the previous homeowner left paperwork from their dealer in the utility area — calling that dealer first is a natural starting point, but you're not obligated to stay with them
• Use OilOutpost to compare prices from multiple dealers in your area

When you call a dealer to set up an account, they'll ask for your address, tank size, and whether you want automatic delivery or will-call. More on that below.

Step 3: Understand Your Delivery Options

Automatic delivery: The dealer tracks your estimated usage based on degree-days (a measure of heating demand based on outdoor temperature) and delivers before your tank runs low, without you having to call. Convenient and prevents runout, but you pay the dealer's current price on the day of delivery without the ability to shop around. Most automatic customers pay close to retail market price.

Will-call (or customer call): You monitor your own tank and call when you want fuel. You control timing, can shop around for the best price, and can buy on dips. Requires more attention but consistently lower prices for people who manage it actively. The risk: if you forget to check the gauge, you run out.

For new homeowners: Automatic delivery is often the right starting move in your first year — it removes the risk of running out while you're still learning the system. Once you understand your home's usage pattern and you're comfortable monitoring the gauge, you can switch to will-call and shop for better prices.

Step 4: Understand Pricing

Heating oil is priced per gallon and delivered by truck. The key things to know:

• Prices change frequently. Unlike a monthly utility bill, the price you pay per gallon fluctuates with crude oil markets — sometimes significantly week to week during heating season.
• Prices vary significantly between dealers. The same day, different dealers in the same town can charge $0.20–$0.50/gallon difference for identical fuel. Shopping around saves real money.
• Summer prices are typically lower than winter prices. If your tank is low in spring and you can top it off, you'll likely pay less than you would the following January.
• There may be a minimum delivery quantity. Most dealers require a minimum delivery of 100–150 gallons. Don't let your tank drop so low that you need an emergency fill for less than the minimum.

Step 5: Know Your Annual Usage

Understanding your home's fuel consumption helps you budget and plan. A rough estimate by home size in a Connecticut winter:

• 1,000 sq ft well-insulated home: 400–600 gallons/year
• 1,500–2,000 sq ft typical home: 700–1,000 gallons/year
• 2,500+ sq ft older construction: 1,000–1,500+ gallons/year

Your actual usage depends heavily on insulation quality, thermostat habits, and how cold your specific winter is. The most accurate way to estimate is to look at your actual usage from your first full year.

First-Year New Homeowner Checklist

• Locate your tank and check the current gauge level
• Find at least 2 local dealers and compare prices
• Set up an account with your chosen dealer before heating season
• Schedule an annual burner tune-up before winter (or verify the previous owner had one done recently)
• Replace the furnace filter if it's a forced-air system (check condition, replace if dirty)
• Make sure you know where the emergency fuel shutoff valve is (typically a red switch at the top of the basement stairs or near the furnace)
• Write down your tank size, dealer phone number, and the emergency line for after-hours calls
• Set a calendar reminder to check the tank gauge monthly October through April
