Key Factors that Affect the Cost of Replacing a Home Heating Oil Tank:

The main factors that affect the price of replacing a home heating oil tank are the tank type, size, location, and proximity to your furnace (also known as a boiler, or home heating appliance).

Below we’ve detailed these key pricing factors for your project, as well as other required processes that CommTank efficiently performs with expertise and specialized equipment, to add value to your project.

Aboveground Oil Tank Replacement Cost Factors

  • Type of Replacement Tank – based on the tank’s location, required functionality and longevity
  • Size of Replacement Tank – based on accessibility and size of space available for the tank
  • Access to Current Tank – based on interior or exterior location, such as crawl space, finished or unfinished basement, garage, etc.
  • Amount of piping needed – based on the tank’s proximity to your furnace, and to the outside of your home for tanks located in basements, or the inside of your home for tanks located outdoors. The two types of pipe to be replaced are the fill and vent pipe (which connects to the outside), and the fuel oil line (or fuel oil pipe) that feeds oil to your furnace.  The tank, fuel line, and valves must also be brought up to current code standards based on regulatory requirements in NH and MA.

"Thank you, Kevin and Nelson for bringing warmth in my house on that very cold day." – Chantal C., Auburn, Ma.

Other Required Costs for Aboveground Tank Replacement

  • Obtain Required Permits – from local and/or state authorities, for tank removal and installation
  • Pump Reusable Fuel from Old Tank – and filter it twice for use in the new tank, without losing its value
  • Fuel Oil Sludge Disposal – to safely dispose of sludge from existing / old tank
  • Custom Cutting and Threading of New Fuel Line Pipes – to fit the specific needs of your heating system

The Lifespan of Indoor Tanks and Outdoor Aboveground Tanks

According to the Massachusetts Department of Environmental Protection (DEP), indoor oil tanks do not last more than about 30 years, and often their lifespan is much shorter.

Outdoor above ground storage tanks that have been uncovered for 10 years or longer should be replaced, since these tanks rust from the inside out, and cleaning or painting their exterior does not usually help to prolong their lifespan.  How old is your oil tank?

The Potential Costs of NOT Replacing a Tank

Aging, faulty or unused heating oil tanks represent a major liability for property owners. According to the MA Department of Environmental Protection, the cost to clean up an oil leak from a home heating system can range from $20,000 to $50,000, with some cleanups costing significantly more.

Just a few gallons of fuel in a tank can eventually leak into the soil, which can contaminate groundwater and require remediation.  The sooner a tank is replaced or removed, the better the opportunity to avoid the expense of environmental cleanup, which can cost hundreds of thousands of dollars.

Heating Oil Costs Remain Constant & Represent Good Overall Value

When adjusted for inflation, the cost of heating oil has remained virtually the same since the 1950’s.

As you consider options for your home’s heating oil system, you’ll discover that CommTank is your best choice for replacement, installation or maintenance of your home’s heating system.

The Steps of an Aboveground Oil Tank Replacement

Advance Work:

  • Conduct a Complimentary Site Visit –to discuss a property owner’s needs and goals; assess any site-issues that could support or impede the project; review the location and condition of the current tank, and review tank sizes and features that will ensure a quality, affordable tank replacement
  • Obtain Project Permits – CommTank will obtain all permits, saving you time and potential headaches. Homeowners in MA and NH are required to obtain permits from the local fire department for tank removals, heating oil tank replacements or tank installations.  We know the regulations and local requirements, and maintain excellent rapport with local officials.

On Site Work:

  • Cover all floors and rugs; remove doors as needed for moving tank into the home
  • Pump remaining heating oil out of the existing tank
  • Once tank is empty, stand it on one side, cut it in the middle, transport it to truck for cleaning
  • Remove existing fill and vent pipes
  • Pump out and remove old fuel line
  • Clean under existing tank, in preparation for new tank placement
  • Bring new tank inside, and assemble on site (install legs, valves, filter, fittings)
  • Set the new tank in place
  • Measure, cut and thread fill pipes to specific site requirements
  • May need to drill new holes through concrete or wood due to pipe height restrictions for existing holes
  • Install the fuel and vent pipes
  • Install the sleeved copper fuel line connecting the oil storage tank to the furnace / boiler
  • Inspect all fittings to ensure everything is tight
  • Pump the previously removed and filtered fuel into the new tank, filtering it again as it is pumped
  • Check the whole system for any leaks
  • Prime and test the system to ensure proper operation
  • Obtain final inspection from local authorities

Additional Steps for Outside Tanks

  • Install a 4-inch thick reinforced cement pad, at a diameter larger than the new tank – since a tank cannot be placed on grass or dirt.  This involves building a form, mixing cement, and letting it cure for 72 hours. A temporary tank is placed until the new tank can be installed on the cement pad, as determined during the initial site visit.
  • Install a Rain Shield – which eliminates the requirement for a shed to protect the tank from the elements
  • Install a Tank Tub – as required by some insurance companies, a tank tub is a polyurethane tub with cover, that functions like a plastic tub around the tank to protect it from the elements

Additional Steps for Garage Placement of a Tank

  • Install bollards to protect the tank – as typically directed per local regulations
Key Oil Tank Parts
  • Fuel Oil Tank Gauge (also called Heating Oil Tank Gauge) – is standard with all new installations
  • Whistle Alarm – is an overfill prevention alarm that alerts the oil delivery specialist that the tank is filled to 90% capacity when the whistle stops
  • Tank Gauge (or combination Whistle and Gauge) – uses a float inside the tank, to read the amount of fuel inside, to a close approximation of 1/8, ¼, ½, or ¾ full

Oil Tank Sizes and Options to Consider

CommTank professionally installs several types and sizes of heating oil tanks manufactured by the two most trusted and proven commercial-grade brands, Roth Industries and Granby Industries. Below is a list of each brand’s features and model sizes that we recommend based on the usage for which each tank’s size, type and design is best suited.

How to Choose the Best Size and Type of Tank for Your Project

Every home has factors that make one size, style or type of oil tank most appropriate. Here are some key factors to consider when choosing a tank for your residence:

  • Doorway sizes – how tall or wide are they, to enable tank entry   
  • Bulkhead availability – if no bulkhead, then tank must enter through hallways and stairway
  • Ceiling height – leading up to and within your basement
  • Finished or unfinished basement – for access considerations
  • Proximity to furnace – fire codes typically require a 5-ft. distance between tank and furnace
  • Length and pitch of driveway – for oil delivery considerations (distance and seasonal factors)
  • Single or Multi-family home – for multiple furnace and tank coordination
  • Garage – Fire department or local inspector must inspect and approve oil tank placement, and typically require installation of protective bollards

Frequently Asked Questions

Oil Tank Replacement FAQs

A tank installed outdoor must meet current State codes for heating oil tanks. A steel tank installed outside must have a shed. Fire inspectors won’t allow the installation without one. A Roth tank with a Roth Rainshield cover is less expensive to install than building a shed and installing a Granby steel tank inside.

Yes, we handle both if required by the town. CommTank’s courier goes to each town office and pulls the removal and installation permits and our crew delivers them on the day of the oil tank installation.

If the current line is up to code then, no. If it isn’t, then we replace it. For homes with a slab foundation, the fuel supply lines can be installed in the attic. Additional fees may apply, depending on length of the fuel line and accessibility.

Yes. We paint all piping (inside and out) to protect them from rust and corrosion. We also think it looks more professional than unpainted steel pipe!

When switching from Granby to Roth it is common to drill new holes to account for the difference in tank height. CommTank plugs holes in cement with a cement patch and uses silicone to caulk wood siding. We recommend that homeowners hire a carpenter to replace wood siding, when weather permits.

Depends on the town. Our courier calls each town before requesting a permit and discusses inspection requirements. If an inspection is required, the inspector is called an hour prior to job completion. Or the fire department will coordinate a time if they aren’t available on the day of installation.

Yes, it needs to be installed on 4” thick concrete pad, whether installed inside or outside, to meet current code.

Typically 4-5 hours for a single oil tank installation. The installation of two tanks can be a full day job. Jobs that require bollards in a garage oil tank installation will be a full day.  Jobs that require the installation of a cement pad (inside or out) will be a 2 phase job. The cure time for a new cement pads is 72 hours.  Depending upon the location of the tank installation a temp tank may also be needed. Tanks installed with a new cement pad in an existing location require a temp tank. Tanks installed with a new cement pad in a new location do not require a temp tank. In cases where the tank is installed in a new location, the crew will install the cement pad on the first visit, then return after 72 hours (or whenever is convenient for the client) and install the new tank.

Most states allow a maximum of 1,325 gallons to be stored in a single family residence. For homes with difficult access points (steep hills or long distances to the fill pipe over lawn and patios) the homeowner may choose to increase capacity to 400-gallons with a larger Roth tank or 550-gallons (2 Granby tanks connected ) to minimize the number of delivery. Winter deliveries can be difficult for fuel companies because of unplowed driveways and paths to fill pipes located behind a home. Reducing the number of deliveries per season may help reduce snow clearing required by the homeowner.

We have seen oil tanks installed with piping connected in series (single fill and vent pipes shared by two tanks) that have led to leaks from the tank top or leaks from tank welds that have burst during fuel delivery. CommTank recommends installing oil tanks with separate fill pipes. This will ensure that the tanks are never over pressurized during filling. Connecting vent pipes in series is acceptable, as the tanks are filled separately, and will never develop back pressure.

Cement cuts in floors are part of our installation fee. We will remove old lines and use the current trench if the old line was not up to code. CommTank’s project supervisor will check the distance between the new tank location and the furnace during a site visit. Extra fees may be needed if there is an unusually long run of supply piping.

The good oil (oil above the sludge level that is not cloudy) is filtered and pumped into a temporary storage tank. The sludge is removed and the oil tank is disposed of. After the new tank is installed, the good oil is filtered again and pumped into the new tank.

275-gallons it the standard or most common capacity. The amount of storage needed will depend on the size of the house and how frequent the homeowner wants to have the oil tank filled.

No, but lines could gel if temperatures are extremely low for long durations. If you have a long existing supply line then the fuel may thicken in the line and gel the oil.  We recommend covering the lines with insulation in this case. CommTank installs all our tanks with a supply and return line. This ensures the fuel is always moving.  We install fuel filters inside the basement and close to the furnace to minimize gelling because an uninsulated fuel filter is more likely to have gelled fuel when installed outside. For homes without a basement, extra insulation is required.  (This is common with mobile homes or ranch style homes without a garage.)
