Q: How does Energy Express know when to deliver to my home? 

A: We compare the number of degree-days since your last delivery and the "K-factor" or "burn-rate" for your home.

Q: What is a “Degree-Day”?

A: A degree-day is the average temperature for that day subtracted from 65.  If the high temperature today was 45 degrees and the low was 25, the average temperature would be 35.  Subtracting the average temperature (35) from 65 equals 30 degree-days.  

Q: What is a "K factor" and what does it tell us?

A: “K factor" is similar to miles per gallon for your car.  When we make a delivery to your home we record the amount of fuel delivered to your home since the last delivery and divide that into the number of degree days since the last delivery.  If we deliver 175 gallons and there were 573 degree days, the K factor would be 3.27.  This means that for every 3.27 degree days that occur, your home uses one gallon of fuel oil.  This tells us that you have 899 degree days before you run out of oil.  If our goal is to deliver fuel before your tank reaches one quarter full, we need to make that delivery 674 degree days after your last delivery.     


Q: What happens if there is bad weather?

A: We track the weather forecasts to anticipate cold weather, snow storms, and other factors that will impact the amount of fuel used to keep you warm.  We also make note of those customers with difficult driveways making sure those deliveries are made before bad weather occurs. 

Q: Will you deliver more oil if I'm on automatic delivery?

A: No.  It's similar to your car, you can only fill up the gas tank until its full and the same is true for your home fuel tank.  Our delivery people can only replace the amount of fuel you have used. 

Q: How can I control the frequency and payment of my deliveries?

A: For delivery frequency and payment options, contact our office and we will help you schedule deliveries or adjust the delivery amounts while making sure you don't run out of fuel.  Payments can be made easier by participating in our budget payment program.

Q: How does Automatic Delivery help you to operate efficiently?

A: By allowing us to deliver automatically, we can schedule deliveries in the same geographic areas and reduce the amount of time spent on the road.  We also believe our system will provides you with better-timed deliveries and keeps you from running out of fuel or requiring emergency delivery.  Frequently the emergency deliveries occur after hours and require additional charges to cover the overtime for our drivers.    

Q: What happens if I run out of fuel when enrolled in Automatic Delivery?

A: In the rare occasion that this happens, we will send a delivery as soon as possible.  We take extra steps to investigate the reason, then make adjustments to the "K factor" to provide deliveries on a more frequent schedule.

Q: How do I know when my next delivery is scheduled?

A: Call our office to find out when your next delivery is scheduled.  If you think we need to make a delivery sooner, just ask, and we’ll deliver to you the next time we are in your area.  Remember that the gauge on your tank may be broken or inaccurate. Together we will make sure you keep warm with our Automatic Delivery program. 

Q: After starting Automatic Delivery, will I ever have to call and adjust my schedule?

A: Only if big changes occur in your home or lifestyle.  These can affect the rate at which your home burns fuel oil.  If this rate changes you may be at risk for running out of fuel oil.  Please call us if you:

  • Add a new room to your house
  • Bring home a new baby
  • Have a family member spend more time at home because of illness
  • Stop using a space heater or wood stove
  • Allow children to move back into the house
  • Install a new oversized bathtub
  • Have a leak from a hot water faucet repaired
  • Turn a basement into a bedroom or family room

Q: When I'm on Automatic Delivery and it's really cold outside, should I call you when I have less than half a tank?

A: There's no need to worry, we monitor the weather and adjust deliveries based on temperature (degree days) and your average useage ("K" factor) to schedule deliveries sooner if the weather requires.  A tank just one-quarter full will last the typical family a whole week even when it's zero outside.  That is plenty of time for us to get a delivery to you.    

Q: Why do you fill up my fuel tank during the summer?

A: Filling your fuel tank during the summer reduces the amount of condensation that will occur in your fuel tank.  Condensation is a natural event that occurs when the temperature inside your tank is lower than the temperature outside.  Filling your tank in the warmer months reduces the amount of empty area in the tank where condensation takes place.

Condensation is water that forms on the inside surfaces of your oil tanks and falls, mixing with the fuel oil and creating sludge.  If there is a large amount of sludge gets pulled into the fuel line, it may cause a blocked fuel line, resulting in a service call to your home.

We treat our fuel with an additive that helps break sludge into smaller particles to avoid fuel line clogging. This allows the product to be burned in your equipment.  It also keeps fuel from clogging lines if your tank is located outside and we experience several days when the weather is very cold. 

If your tank has a large amount of sludge and you are experiencing plugging of your fuel lines, we can treat your tank with other products to disperse the sludge. 

A summer delivery will also eliminate worry when temperatures drop early in the fall.  You’ll have peace of mind knowing that your tank is full and you’ll be ready for the first cold snap of the heating season.
