ConsumerReports.org is a good place to go if you want to see some space heater reviews. You have to be a member to get all the details, but you can always count on Consumer Reports to tell it like it is. You may not even need Consumer Reports, if you do some of your own investigating. You will find that your best space heater is the one that does the job that you want it to do. There are some characteristics that you should look for when deciding on a space heater. First, you must determine what you need it for. If you are looking to heat a garage, or outdoor work room, you might look for a heater that has a fan to spread the warm air. If you are looking for a heater to sit under your desk to keep your legs warm, a small radiant heater might do the trick. Portable space heaters work well when you want to heat up just one room. The different space heater reviews will discuss whether you want to heat up the room quickly for a short period of time or keep the room heated for an extended time. During cool fall days you might just want to get the chill out of the air and you don't want to turn on your entire central heating unit. A portable space heater comes in handy at those times. Take precautions when using a space heater. Some of the older electric heaters will get VERY hot to the touch. Keep them several feet away from flammable things like curtains. Do not try to dry clothes on them and do not allow children to play near. Make sure your heater has the UL listed stamp on it. Your heater should also have an automatic shut off switch in case it is tipped over. Although it's tempting, do not leave an electric heater on while sleeping. With propane heaters there is the risk of carbon monoxide poisoning. If a propane space heater does not specifically list that it can be used indoors, you should only use it outside or with good ventilation. When a propane heater runs it uses up the oxygen in the air and carbon monoxide is created. Since the oxygen in the air is lessened, the carbon monoxide easily enters the body's blood. With increased exposure the victim can lose consciousness and die. Almost all heaters give off the same amount of heat. What you look for and what space heater reviews describe are the differences in convenience features, safety features and the way the heat is directed. Price isn't a very big factor because there is a good space heater for any price range. Don't be fooled, the best heaters are not always the most expensive.
