Be wary of electric space heaters that claim to save money

Many electric space heaters advertise that they can slash your electric bill, but what they don’t advertise is that they can also cause that bill to increase significantly.
Whether it’s a standard electric space heater you see at a hardware store or a “ruby quartz” or “infrared” model advertised in a newspaper flyer, the thing you need to be concerned about is how much power the unit consumes. This is most commonly given in watts. If you can’t find this information on the package or heater itself, be sure to ask the retailer before making a purchase.

 
Many electric space heaters are rated at 1,500 watts. This rating is how much power the space heater uses. You are billed for each kilowatt hour of electricity you consume. A thousand watts is equal to one kilowatt, so 1,500 watts is equal to 1.5 kilowatts.
This means for each hour the space heater is running it consumes 1.5 kilowatt hours of electricity, which costs about 15cents. Doesn’t sound like much, does it? But running that heater nonstop is a surefire way to increase your bill.
If you ran one 1,500 watt space heater for 24 hours a day for a single month it would cost about $104. That’s on top of your normal bill.

 
So where are the savings that are often touted on such items?
An electric space heater can save money, but only if you reduce the running time of your electric furnace or other primary heating system.

 
A space heater could reduce your electric bill, for instance, if you lowered the thermostat on your electric furnace from 72 F to 66 F and used the space heater to heat a single occupied room up to a comfortable temperature.
If, however, you’re using the space heater to heat an area of your home normally not heated such as an enclosed deck, then the space heater is simply an additional cost.

 
Also, keep in mind that if you’re using an electric space heater to supplement a propane furnace, then you may see a drop in the amount of propane you use, but your electric bill will still increase.
Electric space heaters can provide an effective and simple means of heating that cold, unconditioned tool shed, bedroom or other relatively small space, but they should never be allowed to run 24 hours a day and you should always keep in mind the cost of operating such a piece of equipment.

    Glad you made this post. I keep seeing those ads with the Amish making these electric “fireplaces” and just have to laugh as some of the ads show electric lighting in their workshops. I live in an area with a lot of Amish and they strictly prohibit the use of electricity…
