MTR is one of the leading installers of heating oil storage tank systems in Eastern Connecticut.

We offer more than twenty alternative configurations for placement in conditioned environments (i.e. indoor or covered and dry locations like a basement or garage).

The following information is intended to help you make an intelligent decision as to the right configuration for YOUR specific situation.

Indoor Oil Tank Basics

There are many configurations of indoor tanks, so there’s one or more that’s a perfect fit for your situation.

Most recognizable is the traditional single-walled tank (available in 275 and 330 gallon capacities*) like those manufactured by Granby Industries. These oval-shaped tanks, constructed of 12 gauge steel, are 28” wide and either 5′ (275 gallon) or 6′ (330 gallon) long. Magnetic oil level sensor with optional LED display and a “whistling” fill vent complement the new tank installation. The most commonly installed tank types, these single-walled steel tanks should provide many years of safe and economical indoor heating oil storage.

Double-walled tanks, such as those manufactured by Roth are also available and provide the added security of a double-wall containment system. The Roth system offers the added advantage of being better able to fit through doorways, down stairs, and in smaller areas where the traditional oval tanks are inappropriate.

  • Pitch: In order to keep accumulated condensation from causing premature interior rusting, the basement oil tank must be pitched (sloped) towards the filter, allowing the condensation to exit daily to the inline filter.
  • Oil line: Today’s oil line is coated with poly butyl ethylene, which allows the oil line to touch or be poured directly into concrete. This eliminates the corrosive, leak-causing effects of concrete on uncoated oil lines.
  • Venting: Codes now require a 2-inch venting system (same size as the fill) to allow the air to escape your tank as fast as it is being filled. Back in the day, the oil trucks had few or no fuel transfer pumps, mainly allowing gravity to transfer fuel oil into basement tanks. With today’s high volume pumps, fuel oil drivers must take measures not to over-pressurize older in-basement oil tanks in order to prevent leaks.
  • Maintenance: By starting fresh with a clean system your furnace’s efficiency will increase! Having a clean tank you can now maintain your fuel with Fuel-Rite®, which will eliminate sludge deposits not only in the oil tank but in the filters, screens and nozzles which will make your burner most efficient.
  • The New Steel: Steel has been a part of our lives for more than 150 years, yet today we describe it as “new”….with good reason! The steel industry has invested over $50 billion in the latest technologies to make steel more innovative, lower in cost to you and stronger than ever. Here’s an example of steel’s high strength. If the Sears Tower in Chicago (one of the world’s tallest buildings) were erected today, 35 percent less steel would be needed than when it went up in 1974.

(Outdoor) Above Ground Tanks

Home heating oil begins to degrade when temperatures drop below 20ºF. Small wax particles begin to congeal, giving the otherwise transparent oil a cloudy appearance and causing the burner to run inefficiently and unreliably. If an outdoor above ground tank installation is your only option, be sure that a large capacity oil filter is installed as well as a fuel de-aeration device. Outdoor tanks should also be enclosed and insulated whenever possible. We also recommend that a fuel conditioner be added to all home heating oil stored in an outdoor tank. This fuel additive aids cold weather performance by reducing the accumulation of water at the bottom of the tank and subsequent blocking the systems fuel filter.

(Outdoor) Underground Tanks

Outdoor underground tanks can be installed in some locations. Fiberglass tanks offer the benefit of never rusting. they are, however, a bit more expensive that steel tanks. These days, many towns also allow cathodically-protected steel tanks, which are also referred to as STIP 3 Tanks. These tanks are treated with an epoxy resin coating and provide cathodic protection via a zinc anode attached to the tank. Electrical leads attached to the zinc anode periodic testing to ensure continued functionality. Be sure to ask us about our newest line of new tanks approved for underground storage of home heating oil.
