10 Best Oil Heaters


An oil heater consists of metal columns with cavities that are loaded with an oil possessing high boiling point and high specific heat capacity. A heating element at the base starts by heating this oil. The oil in the cavities flows around by convection. The high specific heat capacity allows it to retain the heat for a long time and the high boiling point does not enable it to turn to another form. The heat is transferred to the metal wall through convection, through the walls via conduction, then to the surroundings via convection and radiation.

“One of the bedrooms in my apartment does not have any heat source, so I figured that this one would be perfect for my room since it is a 1500W heater. My room is pretty small, so I had looked up which size heater I should get, and this was the perfect size according to the internet. Now, in the box, you get the heater, the assembly pieces, and a remote. Oh, and the instruction manual of course. I had a hard time reading the manual as it was a tad confusing, but I did figure it out. You do have to assemble the “legs” which was pretty simple to do. I just want to note that when you flip it over to put the legs on it will gurgle but apparently, that is normal. No big deal. Ok, so after you put the legs on you flip the heater back over and wait a minute to 2 before plugging it in. After this gets plugged in you are going to need to hit the main power switch on the side and then you can easily use the controls on the heater or the remote. Side note: the remote takes 2 AAA batteries which are not included. All in all, this is a great heater for the purpose in which I needed to use it. It heats up my room fairly quick and keeps the temperature regulated.” – Amazon’s Customer Review.
