Space Heaters can be a great addition to the cold-weather armaments, and they make those freezing nights comfortable or more accessible. Simultaneously, space heaters are portable and small; they are also pretty efficient enough to heat a single room or a specific part of the place where you live. This way you can easily conserve your electricity bills. This article will help you determine ”How much electricity does a space heater generally consume?”

 People have been using space heaters for quite a few years. But like any electric equipment, there are a couple of things you need to be aware of before purchasing a space heater. Those things will constitute the size, cost, and many watts it uses. These space heaters, capable enough to warm a medium-sized room, generally use around 1.5kW of electricity which will cost roughly 15 cents every hour to warm your room

Categories Of Space Heaters & Their Consumption

In terms of power consumption, several categories of space heaters use different amounts of power and are rated for different types of areas. Below are space heaters that require power input of just 200 watts, and some are ultra-heavy that require about 4000 watts of power input.

200 to 400 watt Space Heater

These space heaters are not built for primary use, but they can save you in extreme emergencies. They are suited to fewer areas such as office cubicles and are often known as personal heaters. They generally use a convection heating method, and the power input can be from 200 watts to 400 watts. They are suitable for 20 to 40 square feet of space but useless for medium-sized rooms.

How Much Does a Space Heater Cost?

To find how much energy your electric space heater consumes, you must check the heater or the owner’s instruction book. The developers usually print and provide the details here. In most cases, space heaters consume around 1,500 watts. But some ecologically friendly space heaters consume energy more efficiently, which is about 500 watts. 

On the other hand, conventional space heaters are expensive and inefficient to warm up the entire house. So, it would be better and more efficient to use it to heat only a single room. Besides that, you can use your insulations to retain heat all inside a single room, and using it more efficiently this way; you can save money.

How Much Power Do Space Heaters Consume?

Do you want to figure out how much energy you will be consuming with a particular kind of space heater? The heater typically shows the electrical ratings in terms of its International System of Units (SI) that are voltage (V), amperage (A), and watts (W) as well. To find out how much power is your heater consuming, you can do it simply by the following formula: Watts(W) = power factor x volts(V) x amperes(A) 

The power factor is generally authorized as 1 unit but can vary. 

So space heaters marked 240 V and 15A consume 240V x 15A x 1 = 3600 watts or 3.6 kW.

Understanding your space heater’s energy usage in wattage, you can next figure out its power rating. This will provide your heating bill’s rough idea. Kilowatt-hours (kWh) is the general unit measured electricity bills.

If you want to find out how much power your space heater consumes in a day, here is how you can do that: 

  • The way to determine the power in a day that a 3.6 kW space heater might consume will be the no. of watts(labeled on the space heater) x the number of hours you used.
  • For instance, it was a cold night, and you used your 3.6kW/hour labeled space heater for 8 hours, then it consumed 3.6 kW/hour x 8 hours = 28.8 kW.
  • It is mostly measured in kW, but if you need to convert it to watts, then you can simply multiply it by 1000
  • Since the electricity cost is affected by the per-unit cost of electricity different for every region, you will need to multiply it with your country’s per-unit cost to determine how much it will cost you for those 8 hours.
  • If you want to calculate your monthly cost, and you use it for 8 hours every day, then you will simply need to multiply the answer with 30
  • Of course, this value excludes taxes and other additional costs. 

As electricity costs vary from one place to another, matching space heaters give different overall directions in other areas. Not to mention, if you are to use the space heater for a long time, it will skyrocket your electricity bill.

Do Larger Space Heaters Cost More? 

So, yeah, it’s true that large heaters consume more electricity than other heaters. On the other hand, the measure is significant because many elements like constitution, structure, and significance contribute to the space heater’s power consumption. 

More giant heaters require more energy for the process and deliver more warmth per square foot than a regular heater. Therefore, as a result, it will cost more.

Conclusion

Electric space heaters cost 44% more than gas furnaces to warm a room. Well, it is to be noted that your bills won’t get too high if you use them properly and in a better way in a very appropriate manner.

It relies on the number of places you want to provide heat to. If you want to warm a few rooms of your house, these heaters are best for you and even cost-effective. But, it is not the case if you are looking to warm your entire house. With the help of being portable and efficient, space heaters are preferred by many people globally. 

Frequently Asked Questions

How Much Will It Cost To Run A 1kW Heater overnight

As mentioned before, the heating cost depends on how large the heater is, and the size of the room that you are heating 

As an example, the price of electricity in the United Kingdom is 28.4 cents per kWh for households. To figure out how much it will cost you in the United Kingdom for running a 1kW space heater overnight for 10 hours:

1kW/hour x 10hours x $0.284= 2.84 US dollars

Multiplying this by 100 converts dollars to cents, and you get 284 cents. It means you would have to pay $2.84 or 284 cents to run the heater for 10 straight hours.

What Is The Cost Of Running A Large 3000 Watt Heater For The Specific 24 Hours? 

It would depend on the place where it is being used once again. Like as said before, in the United Kingdom, you can calculate the electricity cost using the general formula that is Cost of Power = Power Consumed x Time (in hours) x Unit Price

3,000 x 24 x 0.284 = 20,448
Dividing this by 1,000 provides 20.448. So it costs around $20.45 to run a 3,000-watt heater for a whole day.

Now let’s talk about A 1600 Watt Heater For 24 Hours?

 
As above, in the example of the heater being used in the United Kingdom, it will end up costing:
1600 x 24 x 0.284 =10,905.6

Dividing it by 1,000 again will give 10.9056, or it costs $10.9 to run a 1600-watt heater for a whole long day.
 


How Much Does It Cost To Run A 1500 Watt Heater For 24 Hours? 

 
According to the last cases, the method to go through is:
1500 x 24 x 0.284 = 10,224
Dividing it by 1,000 gives 10.224, or simply, a 1.5kW heater is going to cost you around $10.2 if you run it for 24 hours.
 

 


How Much Does It Cost To Run A 500 Watt Heater For 24 Hours? 

 According to the last cases, the method to go through is:
500 x 24 x 0.20 = 2,400
Thus, now divides the whole by the figure of 1000, giving off 2.4. Hence, the total cost to run 500 watts heaters will be around $2.40.
