Different types of space heaters

Ceramic heaters

Ceramic heaters (also known as radiant heaters) work by drawing electricity to heat the ceramic plates which in turn emits hot air.


  • Heats quickly
  • Runs quietly
  • Budget-friendly


  • Stops producing heat once turned off
  • Not good for larger spaces
  • Objects can block heat transfer

Fan heaters

Fan heaters are similar to ceramic heaters in that they draw electricity to heat metal coils, but instead of using ceramic plates to produce hot air, uses a fan system.


  • Provides instant heat and is good for warming up small rooms quickly
  • Compact and portable (easy to move around)
  • Can oscillate hot air
  • Can control heat output with a thermostat
  • Budget friendly


Oil-filled radiators

Oil-filled portable heaters run on electricity and have a diathermic coil which when heated, reacts to the oil to produce warm air.



  • Less portable
  • Not suitable for very small places such as desks
  • Takes longer to warm up (around 20 mins)
  • No oscillation feature
  • The surface can get hot to the touch
  • More costly

Gas heaters

Instead of using electricity, gas heaters use natural gas such as liquid propane gas as a power source to produce heat.

like the Pro Breeze mini heater it also has an adjustable thermostat to control heat, 2 heat settings and anti-tip and heat safety features.

However, the main drawback with the model is the manufacturer states it is not suitable to be used with an extension cord, so has to be plugged straight into a mains socket. This may be an issue if there are no sockets in the area you want to place it in.

Another drawback is that it doesn’t have an oscillation feature, which means it will only heat directly what is in front of it and not the whole space you are in.

The Pro Breeze Digital Oil Filled Radiator is the best all-rounder for heating small rooms and is my personal favourite.

It has a powerful heating system with 3 output settings (1000, 1500 & 2500 watts) which means it also be used in larger rooms if you decide to move it.

It is packed full of features, such as a digital control panel and remote control; it’s on wheels which makes it very easy to move from room to room and has a 24 timer so you can switch it off automatically if you go out or at night

It also has a very useful Eco-Mode for power consumption, allowing you to set your desired temperature with the radiator turning off once your room is warm enough.

The main negatives with the Pro-breeze digital are that it is slightly bigger than the 2 previous models which means it’s not suitable if you want it in really small spaces such as your office desk.

It is also on the top end of the budget for portable space heaters.

4. Kingavon Portable Gas SpaceHeater

Gas space heaters are also a good option if you want to heat a small room that doesn’t have electricity such as a garage or garden outhouse.

However, this model is bigger than all the 3 models on the list which means it’s not a good option for tabletop use or very small spaces. You will also have to buy a gas cylinder separately which can further increase the cost of the overall unit.
