That electric heater is doing a great job, but how much is the bill going to be?

Is it powered by electricity, or pure money-guzzling power?

I’ve always wondered exactly how much an electric heater costs to run. So I did the research, and even made a free calculator.

You are watching: How much does a 1500 watt heater cost to run

On average, a 1,500W heater costs around $0.20 per hour to run on high. This adds up to a cost of $1.60 for 8 hours a day, and $48 per month. The running costs depend on your electric heater’s power, running time, heat settings, and your electricity price.

Here’s the free calculator. Just follow the inputs to get your own personal estimates.

Costs per hour is low, but the monthly price adds up quickly!

Electricity Price Averages

If you’re unsure on your electricity price, here’s some rough estimates you can follow:


Now that you know the possible costs of running a portable electric heater, what are some things you can do to mitigate the cost?

Yes! Here’s a few suggestions.

Insulated or Blackout Curtains

Unless you have very expensive double or triple paned windows with gas between the panes, you are likely looking at heat loss through them.

Blackout or insulated curtains are made from materials with a very heavy weave. They also have an insulated backing that looks something like rubber. The beauty of these is that they will help to keep your rooms warmer in winter, but cooler in summer as well.

They are also very reasonably priced, you can find them in all sizes, and they are available in tons of colors.

Use Weather Stripping or Door Draft Stoppers

If your chilly room has an exterior door, you may need to apply some weather stripping around it. This will seal the weather out. And while you’re at it, and before you hang your new curtains, see if your windows could use some weather stripping as well.

If you have an interior room that’s still catching drafts along the floor, consider getting something called a Door Draft Stopper.

Interior doors typically have quite a bit of space between the bottom of the door and the floor, so something to keep chilly breezes on the other side of it might be your answer.

Put Down Rugs or Carpet

Gleaming hardwood floors are a thing of beauty, but they aren’t terribly energy efficient. And just like we add layers of clothes to shield us from the cold, adding a layer of carpet or rug will do the same for a room.

These simple steps will work wonders at making your heater more efficient. Which means they are a great way to heat your room cheaper.

Is It Cheaper to Leave Heating on Low?

If all things are equal, then yes.

What do I mean by that? Well, since you are leaving the heater on low, do you need to run it longer because it’s taking forever to heat up your room? Or would you run it for the same amount of time you would run it if you had the heat blasting?

Because .5 x 2 = 1. And 1 x 1 = 1 as well. Meaning if you run your heater for a while at a low power, it’s going to cost much the same as it would to run it on high for half the time.

What you could do is take advantage of the tips mentioned above on how to run your heater cheaply. Put those tips in place and run your heater on low, and yes, it will be cheaper.

By now you should be feeling quite educated—I hope—on calculating how much it costs to run an electric heater. Whether you use our calculator and do the math longhand. And really, why would anyone do that?

Both the US and Canada have some variations in the cost of electricity per kWh. Knowing how much you pay locally can help you determine what kind of heaters to buy in the first place and then how much you can run them while staying within any budget you might have.
