Facts On How Much Electricity A Small Electric Heater Use?

Small-size electric heaters are ideal for heating small spaces like bedrooms and bathrooms. You can also place one on your work desk, and it will help you keep working in a comfortable position. Here, we will be telling you how much electricity does a small electric heater use. The answer will clear all confusion. It’s a promise! 


#1. Electricity unit (KWh)

The electricity supplier companies measure the electricity in the Kilowatt per hour so that we will understand it first. The simple definition states as The kilowatt per hour is equal to the electricity used by a device rated for 1000 watts in one hour. 


#2. Formula to calculate electricity usage

The simple formula to derive the electricity usage of an electric device states as: multiply the watt power of the device by the number of hours used. Let us make a guess; you use a 500-watt power heater for 10 hours in a day (500 x 10 = 5000). Then you have to divide the derived number by 1000 (5000/1000 = 5). It means that your small electric heater uses 5 KWh of electricity per day.

You can multiply the per-day consumption amount by 7 and 30 to derive the hourly and monthly estimates. In addition, the heat settings of the heater also decide the electricity usage. For example, a 600-watt heater will consume 600 watts if you use it on the high settings. In contrast, electricity usage will reduce to 70 and 40 percent if the heater is being used at medium and low settings, respectively.


#3. What is the cost of running a small space heater?

Most of the small heaters are rated for 500 and 250 watts of power. A 500-watt heater gives you heat at the cost of 0.7$ per hour and 0.70$ for a week if you use the heater for 10 hours. In comparison, a heater with 750-watt control cuts 0.11$ after every one hour of usage. And if you are a kind person who lets the heater run 24 hours a day, then a 600-watt heater will add up to 60$ to your electric bill monthly. 

These numbers are not entirely accurate; you have to pay the fixed charges on each electricity bill. In addition, the company will also charge extra money if they have installed a new infrastructure. So, the numbers will undoubtedly change, and the estimates, as mentioned earlier, are just for taking a rough idea. You may also be interested to know about electric heater repair.


Ways To Retain Heat In A Room? (To Reduce Electricity Usage)

Retaining heat is no big deal, especially if we have many options to seal our home. Here is the list of materials that you can utilize for efficient heater operation: Weather-stripping: A bit of stripping around the sides of doors and windows air seals space cheaply and effectively. 


#1. Door draft stopper

The drafts beneath the door allow the cold air to come in and the heat out. A simple draft stopper can save you from cold and the rise in electric bills. 


#2. Blackout curtains

These curtains have an insulated covering made of rubber and are great to keep you comforted in winters and the summer season. Plus, the material of the curtains is heavily weaved and blocks the way of heat and cold transfer through it. 


#3. Carpet

Yes! A rug can retain more heat than a bare floor as a slanting floor is super cold in the winter season and makes the heater work harder to heat the whole space. Then obviously, you see a rise in the electric bills. 


Safety Measures When Using An Electric Heater

  • Give a clearance of at least 3 feet to the heater from burnable objects like papers and curtains. 
  • Go with a heater that is certified by an authorized testing company. For instance, UL (Underwriters Laboratories). 
  • Don’t let the heater run in an empty room. 
  • You must ensure that the heating element is protected inside a covering. 
  • Never allow the pets and kids to go near the heater’s body.
