Running a 1500-watt ( 1.5 1.5 kW) infrared heater costs between $ 𝟎.𝟐𝟓 and $ 𝟎.𝟒𝟓 per hour depending on your local electricity rates. For an average of 8 hours a day, this translates to about $ 2.00 to $ 3.60 daily, or roughly $ 𝟔𝟎 to $ 𝟏𝟏𝟎 per month.
Running a 1500-watt infrared heater for 24 hours costs between $𝟑.𝟖𝟒 and $𝟏𝟐.𝟗𝟔, depending on your electricity rate. This continuous usage consumes 36 kilowatt-hours (kWh) of electricity per day.
Generally, a 1500-watt heater can effectively heat a well-insulated room of about 150 square feet (approximately 14 square meters) in moderate climates. For larger spaces or colder climates, additional heating sources or a higher wattage heater may be necessary.
The cheapest heaters to run are generally low-wattage personal heaters, such as halogen heaters or, for larger spaces, oil-filled radiators and infrared heaters that feature, or can be used with, adjustable thermostats to regulate energy consumption. Energy-efficient personal heaters like the Comfort Zone CZ35E are cost-effective choices for localized heating.
Infrared heaters consume the same amount of electricity as standard space heaters, but they often cost less to run. Instead of heating the air, they warm people and objects directly. This targeted approach provides immediate warmth and wastes less energy, potentially reducing your electric bill.
Infrared heaters are excellent for direct, localized warmth because they heat objects and people rather than the air. However, their key downsides include poor whole-room heating, the risk of skin burns or eye damage from prolonged exposure, no residual heat once turned off, and high initial setup and electricity costs.
In most homes, heating and cooling (HVAC) runs up your electric bill the most, accounting for about 40% to 50% of your total energy use.
What Type of Space Heater Uses the Least Electricity? Low-wattage ceramic heaters (like the Ciarra 400W heater) use the least electricity while still delivering effective heat for small spaces. Oil-filled and infrared heaters without fans also tend to use less electricity over longer durations due to heat retention.
Running a 2000-watt (2 kW) heater for 24 hours costs between $𝟓.𝟎𝟎 and $𝟏𝟎.𝟎𝟎 per day depending on your local electricity rates.
Infrared heaters use electromagnetic waves to directly warm objects and people rather than the surrounding air. This radiant technology mimics the sun's natural warmth, delivering instant heat, superior energy efficiency, and improved indoor air quality.
For a standard 24x24 (576 sq. ft.) garage, you will typically need one 30,000 to 50,000 BTU heater, depending on your local climate and insulation. Instead of multiple small heaters, a single ceiling-mounted unit heater or mini-split is usually the most effective approach.
A 1500-watt heater is suitable for rooms up to 150 sq ft.
The safest space heaters are oil-filled radiators and modern ceramic heaters with built-in safety features like tip-over sensors, automatic overheat shutoff, and cool-touch exteriors. Always choose models that are ETL or UL certified and keep them at least three feet away from flammable items.
I intend to use both heaters for 2 hours a day, 5 days of a week. So, to work out your total for the month, we would calculate 4x800 - per hour, of which there are two, gives me 6.4 kiloWatt hours. 6.4 kWh at the 34 pence per kWh rate gives me 217 pence, which would work out at 2.17 per day.
Infrared panels are suitable for all-day heating.
The gradual build-up of heat ensures a comfortable environment, allowing them to be left on for extended periods without making a room feel stuffy.
Yes, space heaters will significantly increase your electric bill if used regularly, as they draw a high amount of power. Most standard portable heaters use about 1,500 watts of electricity. Running one for just 8 hours a day can add roughly $40 to $60 to your monthly bill, depending on your local electricity rates.
Heating and cooling (HVAC) systems are the biggest energy consumers in a typical home, accounting for about 40–50% of your total electricity bill. Water heating, refrigerators, and lighting follow closely behind.
The "30-minute heating rule" is a highly efficient, money-saving thermostat strategy that involves turning your heating system on 30 minutes before you need a space warmed up, and turning it off 30 minutes before you no longer need it.
Conclusion. So, after looking at the different types of electric heaters available, due to its lower power-output, halogen heaters are the cheapest electric heaters to run.
Yes, infrared heaters are highly energy efficient. They convert nearly 100% of the electricity they consume into radiant heat. Instead of wasting energy to heat the air in a room, they use electromagnetic waves to warm people and objects directly.
The cheapest space heaters to run are low-wattage personal heaters (500W) or heaters with Eco Modes. Because you are heating just your immediate area rather than an entire room, you use less electricity.
Heating and cooling (HVAC systems)
Heating and air conditioning are the largest sources of residential electricity use in most climates. According to the U.S. Energy Information Administration, space heating and cooling together account for more than 50% of a home's annual energy consumption.
Your home's biggest energy drainer is your HVAC system (heating and cooling). However, if you are asking about individual plug-in devices, water heaters and clothes dryers dominate active energy use, while cable boxes and small kitchen appliances are the worst "phantom" energy vampires.
Electric heating systems and tumble dryers tend to be the most expensive electrical items to run because they use large amounts of power over extended periods. Other high-cost appliances include electric ovens and immersion heaters. Using these efficiently and during off-peak hours can help reduce costs.
