Oil-filled heaters vs. other Heaters

Oil-filled heaters provide radiant heating. Radiant heating is when the heat comes from a surface. The fins in oil-filled heaters are filled with oil which is heated via heating elements. The oil retains heat well and keeps the radiator warm for long hours.

Ceramic heaters work on convection heat. The heat is produced similar to the radiant method, but in convection heaters, heat is distributed with the help of a fan that blows the heat out to the room.

  1. Oil-filled heaters are quieter than convection heater as they don’t use the fan.
  2. The oil-filled heater is more efficient and provides heat even long after the heating system is turned off. Once the oil gets hot, it takes time to cool down.
  3. Oil-filled heaters provide heat for a longer time and thus save extra units of electricity from burning out.
  4. Oil-filled heaters are excellent if you or any family member is suffering from airborne allergies. As no fan is needed in these units, you are at no risk of adding dust, dander, or another pollutant to the air you are breathing.

Buying Guide for Selecting the Best oil-filled Heater

While selecting an oil-filled radiator heater give a thought to the following consideration.

 Safety Measures

The first thing to be sure is whether the space heater offers all safety measures. With little kids and pets in any family, you can’t risk installing any heating unit without considering its safety. The heater should maintain a cool exterior even when the heating system is powered on. Also, it should shut off automatically in case someone tips-over, or heat goes beyond the set limit.


Electric appliances like heater consume electricity, but you can choose a space heater with eco mode to make sure your electricity bills are not skyrocketing. Eco mode regulates the temperature of the room so that the thermostat automatically shuts off the system when you don’t need it. Once the temperature drops the preset limit, it starts working again.

 Noise Level

Go for the heater with the minimum noise level. In baby’s nursery, and even in your own room, after a hectic day, the last thing you want is a crackling sound coming from the heater. So beware of some models that may not work very quietly.

Power Capacity and Size of the Heater

Consider well where you are going to be using the heater. With their portable size and roller coaster wheels, you can move them around the house where you need the heating. Still, if you don’t have smaller rooms then buying a unit with more than necessary capacity would be an overkill. It will needlessly put a restraint on your budget as well.

 Heat Settings

Weather is never the same; you might need heating in chilly conditions or want just a little warmth on a sunny day. So, make sure the heater allows you to set your preferred heat settings. A standard heater offers three low, medium, and high settings, but some units allow more specific temperature settings. Heat settings also help you to keep the electricity bills in check.


So, oil-filled heaters are your best bet to stay warm and cozy in extreme winter conditions. The best thing about this unit is its sleek and stylish look and its portability. You can wheel them around the house where your family needs the heating, for example in living rooms, dining areas, or bedrooms. No need to buy separate heaters for these areas just go for a portable oil-filled heater and set your required heat settings. With timers, remote controls, and digital thermostats, these advanced heaters are designed to be convenient and user-friendly.
