Your oil tank Equally, if you have an inefficient
Old, Inefficient HVAC
Inefficient heating systems can burn through heating oil too quickly, increasing your oil consumption and raising your heating costs. These inefficiencies may result from a unit's age or a lack of routine maintenance.
How long should 100 gallons of heating oil last? Using the calculation above, 1.7 gallons per hour x 10 hours a day (assuming the number of hours you spend at home is 10 hours) = 17 gallons a day. That means, 100 gallons of oil will last you about six days (100-gallon tank / 17 gallons per day = 5.8 days).
If your 275-gallon tank is full at the start of a 40-degree weather spell, the oil will last for approximately 74 days, or 2.5 months. Granted, you would be lucky if the temperatures in your area drop no lower than 40 degrees during the winter months.
During winter, temperatures often vary between the 20s and 40s, with an average of around 30 degrees Fahrenheit. Under these conditions, a typical home uses about 5.3 gallons of heating oil daily.
An industry average for the life span of an oil tank is 20 years, some tanks last longer and some shorter. This time frame is greatly dependent on the type of oil tank, construction of the tank (meaning thicker walled tanks generally can last longer).
Sealing gaps around windows and doors, insulating pipes, and adding insulation to your attic and basement can prevent heat loss. This helps you conserve oil and reduce heating costs. Simple measures like using caulk around windows can greatly impact your heating bill.
In general, we will see the temperatures fluctuate from the 20s to 40s during the cold season and average at 30 degrees Fahrenheit. Therefore, the average home utilizes around 5.3 gallons of heating oil per day. This means that a full tank will last about 52 days or one month and three weeks.
Turn down the thermostat 10 degrees when you go to work, and again when you go to bed -- a total of 16 hours a day - - and you can save about 14% on your heating bill. Keep a close eye on your tank gauge. Don't let your tank run out of fuel oil which may add special delivery charges.
Purchase Diesel or Kerosene
After you have put the diesel into your fuel tank, allow it to sit for 10 minutes so that any sediment or impurities can settle to the bottom of the tank. Once the impurities have time to settle, power up your furnace and allow clean diesel to run through the fuel line into your furnace.
Oil filters remove contaminants that build up in your oil over time. If your oil is left unfiltered, the particles can wear down your engine's surfaces. Using an oil filter that meets the engine manufacturer's specifications is a great practice. Installing a secondary, or bypass, filter is an even better practice.
Installing quality insulation can be extremely beneficial and help you reduce your heating oil usage. Make sure to check the insulation in: Walls – around 35% of heat lost is lost through the walls. Hot-water tank – Put a jacket over your tank or buy one that's already covered with rigid foam.
Understanding Oil Loss
Common reasons include worn piston rings, a damaged head gasket, or an accumulation of oil in the engine's air-filtration system. Regardless of the specific cause, the result is typically the same: decreased performance and potentially severe long-term damage to the engine.
According to the U.S. Energy Information Administration (EIA), heating oil prices for this winter are expected to remain steady, possibly slightly lower, compared to last season due to recent declines in crude oil prices.
The pricing of heating oil has historically been closely tied to the fluctuations in crude oil prices. As a derivative of crude oil, any change in the latter's price directly impacts the cost of heating oil.
Tank size: 275 gallons (holds 250) Reorder point: 1/4 tank or 68 gallons. Usable gallons between fills: 250-68 = 182 gallons. Number of Days Between Fills: 182 gallons / 5.2 gallons/day = 35 days.
There are several factors that will influence the amount of heating oil you use, such as how often you have your heating on, how many rooms you need to heat, how warm you like your home, how many people live in the property, how much time you all spend at home, and the efficiency of your heating oil boiler itself.
The two main factors that will influence how much oil a furnace uses are the size of the unit and its energy efficiency. The age of the unit is also important as older units are generally not nearly as efficient and will often have some issues that decrease their effectiveness or otherwise cause them to use more oil.
Visible signs of tank damage you should be on the lookout for include discoloration, corrosion, rust on the tank, or denting of your heating oil tank. If you see any of these signs while making your inspection, you need to replace your heating oil tank sooner than later.
Your domestic oil tank should be serviced annually by a registered OFTEC engineer.
