What type of electric heater is most energy efficient?

Author: Porter Hills  |  Last update: Wednesday, April 30, 2025

Electric radiators and infrared panels are among the most efficient forms of electric heating. Ceramic electric radiators deliver an even split of convection and radiation, and infrared panels use radiation as their sole method of heat transfer.

What type of electric heater is the cheapest to run?

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. Shop our range of Halogen Heaters here .

What is the most energy-efficient electric heating?

Electric radiators are almost 100% efficient at point of use, meaning all of the energy they draw from the wall is converted into usable heat that will warm both you and your home.

How much does it cost to run a 1500 W heater for 24 hours?

Answer. To calculate the cost of running a 1500-watt heater for 24 hours in the US, you need to know the electricity cost per kilowatt-hour (kWh). If the average cost is about 16 cents per kWh (as of early 2023), the heater uses 1.5 kW x 24 hours = 36 kWh. Therefore, the cost would be 36 kWh x 16 cents = 5,76.

Are oil-filled heaters more efficient than electric heaters?

The heat-retention qualities of oil-filled radiators are the key factor in their cost-effectiveness. This ability to retain heat makes the radiators very energy-efficient, wasting as little electric energy as possible as it converts into heat energy, warming your room during those harsh winter days.

What's the most efficient type of electric heater?

What are the disadvantages of an oil heater?

The disadvantages of heating with oil
  • The price of furnace oil. Like most petroleum products, the price of furnace oil fluctuates considerably. ...
  • The risk of spills. Oil tanks and other components of oil heating systems are prone to leaks, particularly if they are not properly maintained. ...
  • Air pollution. ...
  • Equipment maintenance.

Which heater uses the least electricity?

Oil-filled heaters are the least efficient type of heater. If you want to save money on your heating costs, then an infrared heater is the best type of heater to choose. An infrared heater will use less electricity than any other type of heater, and so it will be cheaper to run.

What size room will a 1500-watt electric heater heat?

So, a 1,500-watt heater would work well for a 150 square-foot room. Smaller, personal heaters may be about half that wattage. If you simply want to stay warm in one area, say at your desk, a personal heater, such as those designed for a tabletop, may be best.

Are space heaters hard on your electric bill?

If you use a space heater in your home, please be aware that using a space heater can cause a significant increase in your monthly bill. A 1,000-watt space heater operating 12 hours a day will add about $40 to your monthly bill. If the cost does not deter you, remember how important it is to use space heaters safely.

What kind of heater saves electricity?

Electric radiators and infrared panels are among the most efficient forms of electric heating. Ceramic electric radiators deliver an even split of convection and radiation, and infrared panels use radiation as their sole method of heat transfer.

Are oil-filled heaters cheap to run?

Oil filled radiators work in a very energy efficient manner, so can be considered cheap to run in comparison with many alternative designer radiator styles.

Are ceramic heaters better than fan heaters?

Modern models use ceramic elements, which get more resistant as they get hotter (they have a “positive thermal coefficient”). This means they produce heat more quickly and retain it better, making them cheaper to run than fan heaters used to be – as long as you use the thermostat wisely.

Is a ceramic heater cheap to run?

Ceramic heaters are cheaper to run than traditional gas based, or oil filled systems. Ceramic heaters contain heating elements that offer far greater resistance than traditional metal units, this allows for the radiator to generate more heat per watt.

Which heating system uses the least electricity?

Choosing a low-energy consumption heating system for your home. Here are some of the most commonly used low-consumption heating systems today: heat pumps, both geothermal and air source; pellet stoves and boilers; low-consumption electric radiators; and condensing boilers.

What is the cheapest way to heat a room with electricity?

Far Infrared Heaters are the most efficient of all the space heater options and consume the lowest wattage, making them the cheapest to run. Far Infrared is radiant heating and is most easily absorbed by people's skin. In fact, all objects, including us emit and absorb infrared.

Which heater is best for saves electricity?

Reverse cycle split system air conditioners (A.K.A heat pumps) – the most energy efficient electric heater. 5 and 6 star reverse cycle units can be even cheaper to run than gas heaters, producing just one-fifth of the greenhouse gas emissions that a standard electric heater creates.

Do small plug-in heaters use a lot of electricity?

On average, space heaters use 1,500 watts of electricity.

Using a space heater 8 hours per day will use about 84 kilowatt-hours of electricity per week. It costs an average of $51.65 to run a space heater for a month and $258.26 to run for a year.

What kind of space heater uses the least electricity?

Radiant heaters emit infrared radiation that directly heats objects and people within their line of sight, and are a more efficient choice when you will be in a room for only a few hours and can stay within the line of sight of the heater.

What is the difference between a 1500W and a 2000W heater?

Only the speed of heating will be more with 2000 watt. As far as the quanitity of hot water is same, you will need same heat content, for which same energy will be needed. For ex to provide 6000 Wh of heating, 1500 will take 4 hours and 2000 will take 3 hours.

How many square feet will a 5000 watt electric heater heat?

Comfortably, and with an efficient on/off cycling rate about 400 sq. feet. That would be the “sweet spot” between comfort and efficiency. You could easily go to 500 sq.

What is the most effective type of electric heater?

Heat Pumps

They are one of the most energy efficient heating options you can buy. Although all electric heat is 100 percent efficient, these heaters can actually use heat from the environment to provide warmth to your home, which in some cases means you get more heat output than you put into the system.

Is a bar or fan heater better?

Bar heaters provide more comfortable and natural warmth by directly heating objects and people, making them perfect for smaller spaces and personal use. Fan heaters, while effective at warming a room quickly, can dry out the air and cause discomfort over time. Choose based on your heating preferences.

What kind of heater can you leave on all the time?

What is the safest heater to leave on overnight? While it's not recommended to leave any space heater on if you're not monitoring it, oil-filled, radiant space heaters are considered safer than ceramic convection (hot air) types, according to Roberson. Both of these options are safer than open-coil heaters.
