Yes most electric space heaters put out 1,500 watts or 5,120 BTU's. This will heat a standard 150 square foot room. The reason for this is vary simple 120 volt outlets. The standard wall outlet is designed to run a TV, toaster, lamps, Etc. Did you know that your electric hair drier puts out the same amount of heat as a portable space heater? 110v, 115v & 120v all outlets put out one of these voltages. As the years have gone by the electric company has been increasing the voltage to your house. Why? I don't know why other than the higher the better. The greater power the greater the output. The only way you can tell what your voltage is by testing it with a volt meter. I wouldn't run out to buy this meter just to see if you have 115 or 119 Volts. If you buy 3 space heaters for one room will it heat a 450 square foot room? Yes it could in theory. If all 3 heaters are plugged into the same breaker it will never work. This is because of Amps or (currant flow) of electricity. Breakers are designed to protect your house from burning up the wires. To heat this 450 square foot room you will need to have each heater on its own 15 amp breaker. Seeing that most rooms have all the outlets connected to the same breaker this would take some time any a lot of money to fix. A standard portable space heater is designed to heat a small room or to heat a corner of the room. An example is the under the desk heater, it's designed to heat you not the room. Before you buy a space heater know your square footage. And don't forget to see how many other lamps, TV's and computers etc, etc, will be connected to your heater breaker. You could be working on your computer and the heater kicks on and you're in the dark. You just popped at breaker, before you flip the breaker back on start unplugging some electrical devices or you'll be flipping breakers a few seconds. |
