Do Indoor Space Heaters Cost a Lot? How Much Do They Cost?

Most homeowners seek dependable and energy-efficient heating solutions to cope with the chilling weather. To address the demand, people use a variety of indoor space heaters, with each type catering to individual household needs. But it leads to the question about the total cost they will add to your electricity bills. So, read ahead and find out the average energy consumption linked to space heaters and how much they will cost based on your lifestyle.



Average Energy Consumption of Indoor Space Heaters

With indoor space heaters, you can not only cut your reliance on a central heating system but also save a great deal of energy-related expenses. They let you target a single room for heating without turning on the furnaces or boilers to warm up the entire house. That’s definitely a good investment for nurturing a sustainable lifestyle and reducing the overall energy consumption prices.

However, the cost of using a particular space heater depends on numerous factors, such as the heater’s energy efficiency, total usage, and the average rate of electricity in your residential area. For instance, heating (1500 watts) for 8 hours per day will cost you around $2 in the US, which translates to more than $50 per month. Therefore, it would be better to estimate these costs and counter the fluctuating prices in advance.

We have assembled the required data to help you calculate the potential prices of different types of space heaters:


Fuel Type

Daily Cost (USD)

Weekly Cost (USD)

Monthly Cost (USD)





Natural Gas









These costs are based on the following assumptions:

  • Electric heaters consume 1.5 kWh per hour and operate for 8 hours a day.
  • Gas and propane heaters are assumed to have an equivalent consumption of 11.72 kWh per hour and operate for the same duration.
  • The costs of electricity, natural gas, and propane are averaged at $0.13, $0.03, and $0.04 per kWh, respectively.


However, if you step into the market to buy an indoor space heater, consider the following key elements to avoid sky-high bills:

  • Room size
  • Heating capacity
  • Noise levels
  • Energy efficiency
  • Installation facility
