How Much Electricity Does It Use?

Space heaters are portable heating solution that is more convenient than baseboard or central heating. You can move them anywhere in the house. However, before purchasing a space heater, it is important to consider whether you will actually be saving electricity and money.

A large space heater typically consumes around 1,500 watts of power, equalling 1.5 kilowatts of power. In order to determine the expenses of operating a space heater, it is essential to calculate the cost per kilowatt-hour charged by your electricity provider, which usually ranges from 10 to 28 cents per kilowatt-hour.

Assuming an average rate of 20 cents per kilowatt-hour, running a sizable space heater would cost approximately 30 cents per hour. Consistently running a space heater for merely eight hours a day could lead to an additional cost of over $70 on your monthly electricity bill.

How Does A Space Heater Work?

Space heaters are often small, portable units powered by electricity. They can use convection to heat the air in a room by passing electricity through a heating element, or they can use infrared technology to heat a solid surface instead of the air in the room. Some spaces are fueled by the combustion of kerosene, natural gas, wood, or propane.

You should consider the cost of electricity in your area before investing in a space heater. You should also take into account the size of your home and the potential savings. In a small, single-story home, using a space heater might be a budget option. However, in larger multi-story homes, running several units may not be an affordable option.

Things to Consider When Using a Space Heater

Winter can be brutal, but no one likes to shiver in the cold. However, at the same time, a ridiculously high electricity bill is also not the solution. Using space heaters could be a practical solution, but before you invest in one, there are several factors to consider.

First, you should conduct thorough research. The amount of money that you can save by using a space heater largely depends on the cost of electricity in your region. States that rely on renewable energy sources, such as hydroelectric and wind power, typically have lower electricity costs.

For example, in Idaho and Washington, the average cost per kilowatt hour is below 10 cents. On the other hand, power derived from natural gas or oil tends to be more expensive. Hawaii, for instance, has an average cost of over 28 cents per kilowatt hour due to its reliance on imported oil to power generators.

Another important aspect is the size of your home. A space heater in a small home may be a cost-effective option. However, for larger, multi-story homes, you will need to purchase and operate several units, increasing both your upfront investment and operational costs.
