10 Best Oil Space Heaters
for December 2022

Need to heat a room in a hurry? Thanks to the rapid rise of battery-powered space heaters, now you can heat a room without waiting for an oil space heater to heat up. Plus, electric space heaters are far more energy efficient, so you'll save money in the long run.

Our test kitchen has tested various electric space heaters over the years, from tower fans to fan heaters to portable ones. While tower fans provide good circulation in a room, they don't provide much warmth. Fan heaters aren't as powerful as electric heaters, but they'll heat a larger area, making them a practical option. Portable heaters are inexpensive and compact, and they work great in rooms that don't have outlets nearby, like a bedroom. While oil space heaters still heat up a room the quickest, they're bulky and inefficient. Here are the best oil space heaters of 2022:

An oil space heater is a device that is designed to heat oil that burns to create heat.

Oil space heaters work by using an oil heater that heats oil to a high degree. The oil is then forced through pipes that are placed in various parts of the room. The hot air that is created by the heater is then transferred to the room through the vent pipe. Heat is transferred to the room from the heater by using convection, which is the method in which heated air rises and is cooled by the air around it.

How oil space heaters compare to other heaters

Oil space heaters heat the air inside of a room by burning oil, making them economical and environmentally friendly. Oil space heaters are also known as paraffin space heaters. Paraffin oil is heated inside of a metal container until it turns into a gas that is 150 degrees F. The gas then passes through a heat exchanger, where it's heated up to 240 degrees F. The hot air coming out of the heat exchanger is then blown into the room. Because oil space heaters heat the air instead of the water like conventional heaters do, they are more environmentally friendly. Oil heaters emit fewer greenhouse gas emissions and have lower emissions of soot and particulates into the air. They are also more durable than electric heaters, with average life expectancy of 20 years. Most oil space heaters heat up a room in about 30 minutes. The heater's heating element is made of metal and lined with ceramic. The heater's internal components are also made of metal, and the unit is completely enclosed. The heater's heating system operates quietly, making it suitable for use in any environment. Oil space heaters heat a room up to 1,000 square feet. They can also be used in basements, workshops, garages, and porches.
