If you are looking for a heater, but don't want a central heater, then you have quite a few options available to you. One of the most common solutions to such a problem is the space heater. However, there are many different kinds of space heaters, so you will need to make many decisions when purchasing one. The most important distinction between the different types of space heaters is the mechanism by which they deliver the heat to your home. Some are better suited for heating up rooms quickly, while others are more efficient. Here is some information that can help you spot the differences:
- Convection - These units work by heating up the air. Some use fans to propel that air towards a specific location, which can make it good for heating up a chair or some other fixed position. Over a long period of time, convection heaters are the most effective, since that warm air will eventually make the entire room quite warm. However, it does take a while for a convection heater to start being as effective as other options. If you want a room to be heated efficiently, yet not instantly, a convection heater is a good choice.
- Radiant - These units use radiation to directly heat up objects. Fans don't work with these units, since they don't actually heat up the air. This ultimately means that radiant heaters are very good at heating up specific objects in a room (including people), but they aren't very good at keeping rooms warm. A radiant heater will have a rapid, instantly noticeable impact on the temperature of a room, but the room will cool down quite quickly if the heater is turned off or removed.
- Conduction - Conduction heaters usually rely on a heating element that is wrapped around several coils throughout the space heater. Conduction units don't use fans to project their heat at a target, which means that the heat simply emanates from the device. In general, this leads to a situation where the space heater slowly warms up the room in an expanding sphere. The areas closest to the heater will be warmed first, and that heat will slowly expand throughout the room.
If you are looking to heat up an entire room slowly and don't really care about whether or not specific portions are heated first, then conduction can be a good choice. If you want a room to be heated efficiently and with a focus on specific areas, then there are many convection heaters that can suit your purposes. Finally, if you just want immediate heat and don't really care about the room getting or staying warm, radiation is your best bet.
