A lot of homeowners use heating oil to warm their home because it is one of the most comfortable and warmest heating methods available. This means oil tanks are a common component of houses in Pennsylvania and across the USA. If using an oil furnace is new to you, you may be wondering, “How long does heating oil last?” Based on our experience serving thousands of customers over the past 130 years, the short answer is:<\/p>\n
On average, heating oil will last 18-24 months before it may become unstable. If too much moisture gets into your tank, however, the fuel can start to break down. This also will impede combustibility.<\/strong><\/p>\n We only and always carry the highest-grade fuel oil and test it regularly. We also provide a special additive to optimize the efficiency and cleanliness of the burners as part of our oil delivery<\/a> service.<\/p>\n Regular maintenance and quality fuel service will ensure that your furnace runs efficiently and you’ll get the most out of your home heating system. Let’s take a look at how long you can expect your fuel delivery supply to last throughout the year.<\/p>\n Let’s assume the nozzle in your oil burner sprays oil at an average flow rate of\u00a0 1.7 gallons per hour. In 10 hours (the typical amount of time spent at home), you will have used about 17 gallons of heating oil.<\/p>\n Keep in mind, though, that it isn’t likely your oil furnace is going to run for that entire 10 hours.\u00a0 Temperature range will impact the duty cycle of your furnace. The following chart offers estimated oil consumption during specific outside temperatures.<\/p>\n <\/p>\n *assumes a well-insulated house with an average size of 1,800 square feet; assumes oil tank and furnace are well maintained and in good condition<\/em><\/p>\n Let’s say average outside temperatures are around 40 degrees F. A 100-gallon tank providing heat at 17 gallons per day will last 5.8 days (about 6 days).<\/p>\n But remember, there are a lot of variables that impact the efficiency of your home heating system and how long those 100 gallons last. For example, variables can include home size, tank size, home insulation, number of residents, outdoor temperatures, and your level of comfort.<\/p>\nHow To Calculate How Long Your Heating Oil Will Last<\/h2>\n
