Learn more about oil tanks:

Oil Tank Types:

There are different oil tanks on the market.  There are plastic tanks, steel tanks, indoor tanks, outdoor tanks and underground tanks.  You can choose between a single-layer, double layer or integrally bunded tanks.  

A bunded tank means one tank is sitting inside another, with the outside tank being 10% larger than the inner tank.  

We will provide you with the best industry knowledge to lead you to choose the correct type of tank for your needs.

Indoor Fuel Oil Tanks:

Combined Energy Services Installation of Multiple Indoor Fuel Oil Tanks

Indoor fuel oil tanks are generally located in a utility room, basement or garage.  The standard tank is 275 gallons, but models are available ranging from 160 - 400 gallons.

Indoor tanks are not exposed to the elements and do not experience the same hazards as outdoor tanks.  Fewer hazards means less maintenance and improved performance.

In addition to the tank being exposed to the elements, fuel lines are also exposed allowing the possibilty of frozen lines.

When placing a tank indoors:

  • Be sure the indoor oil tank is at least 5 feet away from any combustion appliance.
  • The tank should be installed in a spot where it won't be in the way of everyday activities, but still be easily accessable.
  • Place the tank so it can be inspected on all sides without obstruction.  Keep the recommended clearance distance from any walls or other objects.
  • If the tank is in the garage, protect it from motor vehicles.
  • Place a drip tray below any single-walled tanks, lines, fittings or filters.  This will help contain any potential spills.
  • Seal up any floor drains or conduits that remove water if they're near the tank.  This prevents spills from being sent outside.

Outdoor Fuel Oil Tanks:

Above Ground Tanks:

Combined Energy Services Above Ground Fuel Oil Tank

Above ground fuel oil storage tanks are the simplest, by far.  They require the least amount of maintenance.  And they are the most environmentally conscious choice when considering oil tanks.  

Today's above ground tanks come in many shapes & sizes to fit every application and space within your home!  Some choices CES Offers:

Inspection of Fuel Oil Above Ground Tanks:
Combined Energy Services Tank Inspections
Tanks can leak due to improper installation or maintenance. This can adversely affect the environment and lead to costly cleanups for the homeowner and the state.
To avoid expensive oil spills, install new heating oil tank systems in accordance with National Fire Protection Association Code Standard 31 and perform routine maintenance on both old and new tank systems.
CHECKLIST: The following checklist can aid you in proper maintenance of your home heating tank system. 
Ask the following questions and if the answer to any of them is "NO," contact Combined Energy Services.  (It is best to contact a certified professional to correct the problem. DO NOT attempt to correct problems yourself.)
 Are tank legs and foundation stable?
 Is the tank surface free of rust, weeps, or excessive denting?
 Is the area around the filter and valves free of drips or signs of leakage?
 Are the oil lines between the tank and the furnace enclosed in protective tubing? 
 Is the tank protected from falling snow or ice?
 Is the tank vent unclogged and free of ice, snow, corrosion, or insect nests?
 Does the tank system have a vent alarm and is it working properly? (Ask oil delivery person if the alarm whistles when full.)  
 Are the areas around the fill pipe and vent pipe free of signs of spills?
 Are you using an average amount of oil for your system? (Using more oil than normal usually indicates a problem with your system.)

Under Ground Tanks:

With today’s growing concern about buried fuel storage tanks, the only underground fuel tanks that CES recommends and sells are double wall, polyurethane jacketed tanks. 

While many plumbers and contractors look for the quick, cheap installation – we never recommend nor would we sell a  “plain” steel fuel storage tank for buried service.  All steel in the ground will eventually deteriorate.  It’s not a question of “if”, it’s a question of WHEN. 

Very often these contractors are installing the cheapest tank they can buy, scratch the already too thin protective painted coating and rarely provide electric potential isolation through the use of magnesium anode bags or dielectric unions on piping connections.  These short-sighted quick buck moves put YOU as the property owner at risk in the long term.  One leaking fuel storage tank can lead to tens of thousands of dollars in clean-up costs.  

CES is a leader in environmentally conscious fuel tank installations using only the most advanced technology to protect your property for years to come.  When we install your buried fuel tank, you can rest easy knowing it’s been done right and within environmental compliance regulations. 

Indoors vs. Outdoor Fuel Oil Tank:

When choosing fuel oil, you have the option of placing your tank indoors or outdoors.  While the consumer can freely choose the location of their tank, experts say it's better to have an indoor tank than an outdoor one.


Why put the tank indoors?

  • Outside tanks are subject to condensation inside the tank with changing temperatures putting water into your oil creating winter service problems & eventual corrosion inside your tank.
  • Ice & water dripping from your roof can break oil lines coming from tanks.
  • Outside tanks settle or may become unstable, creating an environmental risk.
  • Outside tanks require the use anti-gel additives or a kerosene blend in the winter to keep home heating fuel oil from “gelling” in extremely cold temperatures.

Oil Tank Leaks:
Tank Removal, Tank Replacement & Soil Remediation

If your buried fuel tank is over 20 years old, we highly recommend you consider having the tank removed from service before you have a problem.  CES can handle the process from start to finish protecting you from serious environmental violations and costly clean-ups.

EPA SealWhile CES doesn’t recommend installation of underground tanks unless protected double walled, other tanks are acceptable if installed correctly. 

United States Environmental Protection Agency (USEPA) has a wealth of information on prevention of underground fuel storage tank leaks as well as regulations.
