What Is A Space Heater?

When the weather gets cold, you will need an efficient space heater that provides just enough warmth for a small area. They work great during those in-between weather days, such as the first cold day of the season or the end of winter transitioning into spring. Space heaters are a type of auxiliary heating device that is intended for use with a central heating system but works as a stand-alone unit that doesn’t require setting up a permanent heating system.

There are different kinds of space heaters, including convection, radiant, and combination heaters. Space heaters are portable and come in a variety of sizes and styles.


Good for heating up large spaces. This type of space heater is designed to warm the air in the intended room and not to warm people. It produces rising hot air that causes the cooler air to fall to the floor. This circulates the air in the intended space, much like a convection oven.

Radiant and Infrared

Radiant space heaters are great if you want to heat up an area in a hurry through the use of infrared rays. However, they aren’t always the best choice for warming up a large room. They are often able to heat a 1,000 square foot room, whereas a fan-forced model may only cover a 400 square foot room. They emit warm orange light. Radiant space heaters are intended to heat both humans and household objects in the space and not specifically heating the air. Anything or anyone sitting in the front will feel the heat. This also means that if anything that is flammable gets in front of the heater, it could become a fire hazard.

Micathermic Panel Heaters

 This is a hybrid heater that releases 80% convection heat and 20% direct radiant heat. Usually, these models are lightweight and even wall mountable. They are quiet and do not emit any light, so they are ideal for a bedroom. They use the airflow of a room to circulate the heat, which means circulating dust is not an issue.


 A combination heater is very durable and stands up to everyday wear and tear. These heaters provide an efficient distribution of heat given you a perfect mix of both worlds. They make use of a powerful fan for heat distribution throughout the heated space.

Ceramic Fan-Forced Heaters

Fan-forced space heaters are very versatile and offer many options:

  •    Oscillation – The heater can either remain stationary or oscillate to disperse heat throughout the room.
  •    Timer – Setting a time on a heater is a convenient way to make sure it only runs during specified times.
  •    Remote Control – Convenient options like a remote control allow you to adjust the settings without getting up.
  •   Digital Thermostats – Lighted thermostats make it so that you can see it even when the lights are turned off in the intended room.
  •    Multiple Fan Settings – Low to High-speed settings make it so that the room can be heated faster on high or save energy on low.

Amount Of Heat

Most heaters use between 600 to 1500 watts of electricity. The bigger the wattage, the more heat it will produce and the more power it will use.

Consider the Size Of The Room

When choosing a space heater, keep in mind how big the room is that you want to be heated as well as the power rating.

Oil-Filled Heaters are inertia radiators that use heat transfer fluid to release radiant heat. These heaters quickly heat up but are cost-effective than a whole-house central heating unit. They tend to be heavy and are often mounted on wheels.

Gas Space Heaters do not need electricity to run but tend to be bulky. In a ventilated workshop or garage, sometimes Gas Site Heaters are used because they are space heaters designed for use on work sites.

Kerosene Heaters require kerosene to work and are either conventional or forced air.

Additional Tips For Selecting The Right Space Heater

  •  Carefully calculate the power rating required.
  •    Consider the space and type of the intended room. 
  •    Choose one with several heat settings.
  •    Consider noise level and ventilation for gas or kerosene models.
