A space heater provides a convenient way to quickly increase your room temperature. It can help you lower your power bill if you choose to heat your room only, or it can provide you with some extra heat in case your room is a bit too cold. Photo by Davis Staedtler

Some of the most common heater types include radiant and convection heaters.

Radiant Heaters

These space heaters use metal or some other glowing element, such as quartz, and a reflector which directs the heat into a desired area. They usually take little space and work very fast. If you want to heat a limited area only, this might be your preferred choice.

Convection Heaters

Convection heaters usually use a metal heating element and some of them have a fan to pull the cool air and heat it up before distributing the hot air. Those heat up the space very quickly, although due to the fan they can be sometimes a little noisy. This doesn't make them suitable to keep you warm at night.

However, not all convection heaters have a fan. So-called unassisted convection heaters have a large surface heating element that passes the heat directly to the surrounding air. These heaters, due to the size, take a few moments to get hot, but are very effective and quiet. Also, since there is no fan involved, no air and dust is disturbed and circulated by it. For this reason unassisted convection heaters are especially suitable for people with allergies.

There are a few popular designs of convection heaters:

Oil-filled Portable Heaters

This is one of the most popular designs out there. Because of the size and the oil content they can be a bit slower to get the room warm. On the plus side they will keep warm for a while after switching them off.

Ceramic Heaters

Room heaters of this kind use a blower fan to pull the air over ceramic elements and to distribute heat. They work fast, but can be noisy, especially at the highest setting.

Baseboard Heaters

This space heater design that takes hardly any room space. Baseboard heaters have a low profile and can be nicely integrated with the interior of your room.

Wall Heaters

An advantage of wall heater is that they take up very little space once installed.

Determine Heating Area

After you make up your mind about the type of space heater you would like to use, it's important to know what area you want to keep warm. This will determine how powerful the heater will need to be to handle the size of your room. For example, a 2000 Watt heater can cover an area of roughly 200 square feet (or 20 square meters).
