If you’re curious how much energy a space heater uses because you want to figure out roughly how expensive it’ll cost to run, or you want to ensure that your home’s wiring can safely handle the load, you’re in the right place. Since this is The Infrared Heaters Organization, we know a lot of people are looking to know all sorts of things about heaters and using them, and one of the most common questions is “How much energy does a space heater use?”
The answer depends on which heater you have, and which power setting you’re running it on. The higher that you have it set, the more heat it will generate, the hotter the unit itself will get, and the more electricity (energy) will be used, too.
How to calculate how much power your space heater needs: First things first, look for the wattage listing on the unit itself, or in the instruction box, or even on the box if you still have it. It’ll likely be somewhere around 1000 or 1500 watts, which could also be referred to as 1 kilowatt or 1.5 kilowatts, respectively.
But it’s not just a flat number. As time passes, your heater will use more and more power the longer it’s on, or the higher it’s set to. So, let’s say you run it for 6 hours per day, you’ll multiple that 1000 or 1500 watts by 6. Then, divide it by 1000, then multiple that by the hourly rate that your electricity utility company bills you for (You can find this on your bill, or most likely online if you have a profile, or just call in and ask them…)
Is it worth it? Does this save money?
The main reason that people wonder how much electricity their infrared or space heaters are going to use, is either because they don’t have a furnace that heats the whole home, or the furnace is broken and they’re wondering about just winging it with space heaters, or it doesn’t get cold enough to justify a more permanent heating option… whatever the reason is, there are some instances where this will save money.
If you turn down your regular furnace that heats the whole home, and you use a space heater in the room you’re spending most of your time in, this is a good way to save money. The space heater will use less electricity than a furnace, and is much more efficient since it’s only trying to heat a small area of the home.
Space heaters are less efficient overall than certain other methods, BUT they’re much more precise, so you’re able to heat a smaller area and even though it’s not as efficient, it’ll still use less power overall because you’re heating a smaller area.
Here’s a common question: “Can space heaters save money?” We’ve answered it in-depth, just follow that link.
To sum it all up, space heaters are great as more of a temporary solution, if you get chilly during a couple of months, space heaters can be a great, and affordable way to stay warm. For your main source of heat through a long winter, however, they probabally aren’t going to cut it.
Next time you’re wondering how much electricity does a space heater use, just take a look at the box, and figure out how much you’re paying for electricity and how often you’ll be using the heater, and you’ll have your answer.
