Q – Is kerosene a dangerous fuel option?

A – In short, kerosene is no more dangerous than any other fuel. Kerosene is a great option for customers who live in mobile homes or have outdoor fuel tanks.  However, homeowners and business owners alike should always remember that heating equipment and its fuel should always be monitored and serviced to ensure maximum safety.

Kerosene has a bad reputation because when it burns, it consumes oxygen. When a kerosene heater is burned for a long time in a small, unventilated place, the lack of oxygen can be dangerous to residents. However, with proper ventilation and common-sense safety, kerosene is as safe as any other fuel you may choose. It has the added benefit of being resistant to gelling, a chemical reaction that happens when fuels are exposed to cold weather. Since gelling can cause damage to fuel lines and require costly repairs, kerosene is a favorite in colder climates like New England. Click here to place your kerosene order!
