How efficient are fuel oil furnaces?

Modern oil furnaces have annual fuel utilization efficiencies (AFUE) in the 80 to 90 percent range, while new gas furnaces have AFUE ratings from 89 percent all the way up to 98 percent. Furnaces over 10 years old might be more than 30 percent less efficient than new models.

How much fuel does an oil furnace burn per hour?

between 0.8 and 1.7 gallons per hour
On average, an oil-burning furnace will burn between 0.8 and 1.7 gallons per hour while in operation. So, if you have a one-bedroom home, requiring a 300-gallon tank, and you keep your furnace running for 10 hours, you’ll need to fill your rank after 17 days.

How much fuel oil does a furnace burn a day?

Heating Oil Consumption Based On Temperature A typical home uses about 2 gallons of heating oil per day if the outside temperature is 50 °F. So, if you’re using an oil tank with a 275-gallon capacity, it can last about 137.5 days or around four and a half months when full.

Is 85% efficiency good for oil furnace?

Here are some efficiency guidelines for typical furnaces according to the U.S. Department of Energy: Low-efficiency (older systems): 56-70 percent AFUE. Mid-efficiency (older or newer systems): 80-85 percent AFUE. High-efficiency (mostly newer systems): 90-98.5 percent AFUE.

What is more efficient gas or oil furnace?

The Annual Fuel Utilization Efficiency rating indicates a furnace’s efficiency. Even though oil produces more heat per BTU, gas is generally considered more efficient. Oil furnaces offer AFUE ratings between 80% and 90% while gas furnaces offer ratings between 89% and 98%.

How efficient is a 40 year old oil furnace?

How efficient is the average 35-40 year old furnace? 80% at best. Likely lower if it is indeed close to 40 yes old. A lot of savings to be had with a new furnace 95% with a ecm blower motor.

Is a 96 furnace worth the extra money?

A 96% AFUE gas furnace is top of the line, powerful, and efficient. In fact, a 96% AFUE gas furnace is one of the most efficient gas furnaces available. Not to mention that it is a highly effective tool to heat your home in even the coldest conditions.

What is a good efficiency rating for a furnace?

High efficiency furnaces offer 90% or more AFUE. These days, 95% AFUE is a common rating among new gas-powered furnaces. So a 95% furnace is more efficient than an 80% furnace.
