Now that you have explored our top 11 picks for oil-filled space heaters, let’s understand how these devices work.

How Does An Oil-Filled Heater Work?

Oil-filled heaters are electrically charged and use electricity for heating rooms. The electrical element in the heater is fully submerged in the thermal oil reservoir. When the heating element heats up, warmth is created and transferred to the radiator body. This warmth is further transferred to the surroundings and warms the room. This device efficiently warms up the room without drying up the ambient air present inside it.

How are oil-filled heaters different from ceramic heaters? Find out below.

Oil-Filled Vs. Ceramic Heaters

Oil-filled heaters warm up the rooms by the air created from a hot surface. The oil in the reservoir is heated through electric heating elements and transferred to the surroundings. Oil-filled heaters retain heat excellently and keep the heater warm for hours, consuming less energy. On the other hand, in ceramic heaters, convection heat is produced when the element is charged with electricity. Ceramic heaters also have a fan that blows heat through the element to spread adequate heat across the room.

There are several differences between oil-filled and ceramic heaters:

  • Oil-filled heaters operate silently as there are no fans, unlike the ceramic heaters.
  • As oil-filled heaters have oil that remains hot for extended periods, they offer long-lasting heat compared to ceramic heaters.
  • Oil-filled heaters are ideal for large-sized rooms as the continually rising heat can keep large rooms heated for a while.
  • Ceramic heaters offer instant heat due to the fan element, unlike the oil-filled heaters that take more time to heat up.

Oil-filled heaters offer many benefits compared to conventional heaters.

Benefits Of Oil Heaters

  • Low Wattage

Oil-filled space heaters have low wattage and generate maximum heat. These models are easy to store and can easily fit under a desk or in a narrow space.

  • Provide Warmth For Hours

Oil-filled heaters use oil for heating, and the oil remains hot for hours after shutting off the heating element. Thus, your room will remain hot for hours once you use the heater.
