Genie’s Diary, Heating Oil Tank

Dear diary,

What a weekend we had! Seventy degrees. Sunny. And warm. Is it really December?

Well, we can all appreciate the savings to our heating oil budget. The recent weather has been pretty easy on the ole heating oil tank.

Speaking of tanks, I know this time of year a lot of people start thinking about their heating oil tank   and asking questions, like:

Are there different types of heating oil tanks?

There are basically 3 types available:

  • Steel: These are the least expensive cost wise and the most common. There are both above and below ground models, and every tank must adhere to rigid UL construction standards for safety.
  • Fiberglass: Fiberglass heating oil tanks, although less common, largely eliminate leakage and sediment concerns relating to rust. Most commonly used for underground replacement, fiberglass is now approved for above ground installations as well.
  • Combination: A more advanced heating oil storage tank is the polyethylene lined double-wall tank. The inside tank is made of a thick, durable polyethylene material and covered by an outer shell constructed of galvanized steel. The polyethylene won’t rust or corrode, and the galvanized steel is extremely durable and resistant to abuse. Both enclosures are pressure tested to comply with strict UL performance standards.

Are there different sizes?

Here in Maryland the most common above ground sizes for heating oil tanks, either in the basement or in the yard, are the 275 and 330 gallon models. Other common above ground tank sizes in the Mid-Atlantic region include 160 and 330 gallons, but are available ranging up to 400 gallons.

What size is yours?

If it’s above ground in the basement or yard, and measures about 44” high by 60” wide by 27” deep, then it’s a 275 gallon tank.

What should it be mounted on? 

No matter what the size, an above ground tank filled to capacity is heavy. For example, a 275 gallon heating oil tank weighs more than 2,000 pounds. So all above ground tanks should be placed on a stable surface. Outdoor tanks should be mounted with metal legs on concrete support pads that stand on compacted ground. If the legs rust out, concrete cracks or the ground gets soft, the tank can fall over and leak. Indoor tanks should be mounted on a basement concrete floor.

How much heating oil will I need this year?

I’ll refer everyone back to my September 7th blog for that one. 

How long do heating oil tanks last?

If properly mounted and maintained, the answer is – a long time. There is no absolute time frame for heating oil tank replacement. A periodic visual inspection is strongly recommended to avert problems that could potentially shorten a tank’s lifespan. Look for rust, dents, oil stains and any signs of settling on above ground tanks. Below ground heating oil storage tanks are difficult, if not impossible (even for Genies) to inspect visually, but it’s still important to check the site for any obvious signs of rust or leakage. Inspecting your tank or tank site at the beginning and/or end of the heating season is a good habit to develop.

And the last question is… What’s the latest heating oil price?
