Space Heaters: Are They A Budget Buster Or A Cozy Necessity? Find Out

The arrival of chilly months often brings the question of whether space heaters are an expensive solution for supplemental warmth. To answer this question, we delve into the factors that influence the cost of running a space heater, ensuring an informed decision for your heating needs.

Factors Determining Space Heater Running Costs

1. Type of Heater

• Radiant heaters: These heaters emit infrared heat, directly warming objects and people in their vicinity. They are relatively efficient, typically using 1,500-2,000 watts.
• Convection heaters: These heaters circulate warm air, heating the entire room. They consume more energy, generally using 1,500-2,500 watts.
• Ceramic heaters: A hybrid between radiant and convection heaters, ceramic heaters use a ceramic element to generate heat, offering a balance of efficiency and warmth. They typically consume 1,500-2,000 watts.
• Oil-filled heaters: These heaters use oil as a heating medium, slowly releasing heat over an extended period. They are less efficient than other types, consuming around 1,500-2,500 watts.

2. Wattage

The wattage of a space heater indicates its power consumption. Higher wattage heaters generate more heat but consume more energy. Consider the size of the space you need to heat and choose a heater with an appropriate wattage.

3. Run Time

The duration of heater usage significantly impacts its running cost. Leaving a heater on for extended periods will consume more electricity. Use space heaters judiciously, targeting specific areas or durations for optimal energy efficiency.

4. Energy Efficiency

Look for Energy Star-certified space heaters, which meet strict energy efficiency standards. These heaters consume less energy while delivering comparable warmth, reducing your operating costs.

5. Insulation and Climate

Well-insulated homes and mild climates contribute to lower space heater running costs. Heat loss is minimized in these conditions, allowing you to use the heater less frequently and for shorter durations.

Calculating Space Heater Running Costs

To estimate the cost of running a space heater, follow these steps:

1. Determine the wattage of your heater.
2. Convert the wattage to kilowatts (kW) by dividing by 1,000.
3. Multiply the kW by the cost of electricity per kilowatt-hour (kWh) in your area.
4. Multiply the result by the number of hours you plan to use the heater.

For example, if you have a 1,500-watt heater and the cost of electricity is $0.12 per kWh, and you plan to use it for 4 hours:

“`
(1,500 W / 1,000 W/kW) x $0.12/kWh x 4 hours = $0.72
“`

Therefore, running the heater for 4 hours would cost $0.72.

Tips for Reducing Space Heater Running Costs

• Use space heaters in small, enclosed spaces.
• Set the heater to a lower temperature setting.
• Use a programmable thermostat to automatically turn the heater on and off.
• Keep windows and doors closed to minimize heat loss.
• Consider using alternative heating methods, such as warm blankets or clothing.

When to Use Space Heaters

Space heaters are ideal for:

• Supplementing heat in poorly insulated rooms.
• Providing warmth in specific areas, such as workspaces or bedrooms.
• Temporary heating during power outages or equipment failures.

When Not to Use Space Heaters

Avoid using space heaters:

• As a primary heating source for large spaces.
• In areas with flammable materials or near water.
• In unattended rooms or overnight.

Final Thoughts: Are Space Heaters Expensive to Run?

The cost of running a space heater depends on several factors, including the type, wattage, run time, energy efficiency, and local electricity costs. By considering these factors and implementing energy-saving tips, you can minimize the operating expenses of space heaters while enjoying the warmth and comfort they provide.
