Bottini Fuel Discusses When You Need To Replace Your Oil Tank


Bottini Fuel often receives questions from homeowners about when to replace oil tank units. Some of the most regularly asked questions are, do I need a new oil tank, and should I replace my oil tank?

Replacing your oil tank is a crucial investment. Exactly how long do oil tanks last? Tank failure is the emblematic indicator that it is time to swap indoor oil tank units, though you will often be able to spot the warning signs long in advance.

Exactly How Long Does an Oil Tank Last?

In most cases, an oil tank will last around 15 to 20 years — or roughly two or three times the length of the average residential tenancy. Consequently, if a tank is approaching its 15th year at the time you sign your occupancy agreement or close on your home loan, you could be facing an extra expense to all your other move-in expenses. Granted, an oil tank could last significantly longer than average with proper maintenance and periodic upkeep. Irrespective of how a tank performs, however, you should have an expert inspect the tank by its 15th year for indications of wear and possible performance problems down the line.

How Can I Tel If I Need a New Oil Tank?

When it comes to anxieties about home-heating systems, landowners will often wonder about when the most opportune time is to change an oil tank. This fear can be especially demanding when you first move into a home. After all, the last thing you want is to find out about is an aging and deteriorating oil tank the hard way. When you purchase a house, you should have the oil tank examined, even if you know it’s only a couple years old. The tank may seem to be in optimum condition to the naked eye, but you never know precisely how well the previous homeowner preserved it.

Signs Your Oil Tank Needs to Be Serviced or Replaced

While a plumbing expert should provide the definitive diagnosis, there are signs you could look for as a landholder to get a sense of whether your oil tank is either deteriorating or due for repairs. Some of the most telltale signs of distress include:

  • Rust and dents — Erosion and dimple marks indicate something is wrong with how the oil tank functions.
  • Wet spots — The existence of wet spots, either beneath the tank or on its surface, is an indicator of problems.
  • Unstable legs — In many cases, difficulties with an oil tank will be the outcome of faulty set-up. A dead giveaway of this problem is when the legs appear uneven, in which case the tank would have trouble operating at its full capacity. If the legs appear unbalanced in any way, have the tank examined instantly.
  • Exposure to frosty elements — If the tank is outside your house or positioned in an area where winter environments like snow and ice could make their way into the tank, have the tank checked for possible signs of damage.


If any of these problems arise with your tank, have the unit examined by a qualified technician from Bottini Fuel, who will identify the problem and let you know your options, be it repair work or an all-out replacement of the oil tank.
