Calculate your costs using this guide
Electric-heating costs depend on the heater’s power, how long it runs and the electricity price on your bill. This guide uses transparent worked examples so you can substitute your own local rate.
There is a multitude of less carbon-heavy heating alternatives available, such as electric heating, but the higher cost of installing and running this can be prohibitive.
But how much does it actually cost to run an electric heater, and how does this stack up against other more traditional heating alternatives? We’ve run the data so that you can make an informed decision.
What is electric heating?
Electric-resistance heaters convert nearly all of the electricity entering the appliance into heat at the point of use. It refers to any heating system that uses electricity as its main energy source and includes storage heaters, electric boilers, electric heat pumps, and underfloor heating.
With climate change accelerating at a terrifying rate, the potential for eco-conscious, low-carbon, electric heating systems is enormous. For example, for every 1 kWh of electricity a heat pump uses, it produces 2 to 4 kWh of heat energy, making it up to four times more energy efficient than traditional furnace heating.
What are the advantages of electric heating?
- Economical – The initial cost of electric heating is low compared to other heating types such as gas. There are no moving parts involved in electric heating systems and because of this, wear and tear-related issues and maintenance costs are greatly reduced.
- Free from pollution – Electric heating does not release ash or dust like coal heating and is, therefore, one of the cleanest ways of heating a house.
- Predictable at the appliance – Electric-resistance heaters turn nearly all incoming electricity into heat, while heat pumps can deliver more heat per unit of electricity by moving heat rather than creating it directly.
- Safe – With other gas furnaces and boilers there is a small risk of carbon monoxide gases escaping that can cause carbon monoxide poisoning. Electric heating poses none of these risks
- Lots of different heater types available – These include electric radiators, heated towel rails, and fan heaters for smaller spaces
- Quieter to run – Without the need to pump hot water all around the house, electric heating solutions are generally much quieter than gas central heating systems – no banging pipes or humming boilers!
- Complete control – It is much easier to control the heating in individual rooms or spaces using electric heating systems
What are the disadvantages of electric heating?
- Electric heating can be more expensive – Electric is generally more expensive to run on a daily basis than gas, although this is likely to stabilize as we reduce our reliance on fossil fuels to generate this energy
- Slower to heat up – It can take slightly longer for some electric heating appliances to heat up fully from cold
What are electric heaters?
An electric heater is an electrical device that converts an electrical current into heat. They contain electric heating elements that provide the fire that gives the heater its warmth and is controlled on and off at the flick of a switch.
What is a electric heating element?
Electric heating elements are usually shaped like a coil, a ribbon, or a strip of wire. When an electrical current runs through the element, it glows red hot and converts the electrical energy into heat, this heat radiates in all directions.
Heating elements are used in most household appliances that heat up – toasters, hair dryers, kettles, and electric stoves.
About the cost of electricity
Electricity prices vary by state, utility and tariff. The U.S. Energy Information Administration reports a 2025 national residential average of 17.30 cents per kWh, but the rate on your latest bill is the correct figure for your calculation.
What drives the cost of electricity?
There are a number of factors that influence the cost of electricity, with even small changes to any of these factors resulting in an increase or decrease in the cost. These include:
1. Demand
2. Availability of generation sources
3. Fuel costs
4. Power plant availability
5. Supply constraints
6. Weather
7. Time to delivery
Heating with electricity Vs other energy sources
The EIA Winter Fuels Outlook final estimates for winter 2025–26 put average household expenditures at $686 for natural gas, $1,146 for electricity, $1,286 for propane and $1,749 for heating oil. These are broad national comparisons, not quotations for switching systems; weather, region, home efficiency and equipment all materially affect the result.
What are the different types of electric heaters and how much do they cost to run?
Electric radiators
Electric radiators are standalone units filled with either a thermal fluid or electrical element. They heat up when switched on and fill the air surrounding the radiator with warmth.
Electric radiators typically use around 2,000 watts of electricity and cost about $12.60 per week when used for five hours a day at $0.18/kWh.
Space heaters
Ideal for smaller spaces and are usually lightweight and portable. Ideally, space heaters should be used as a secondary source of heat and for short periods of time as they can be costly to run.
Space heaters are available in a number of different types, including forced-air heaters, ceramic heaters, and radiant heaters.
Most space heaters use about 1,500 watts; at $0.18/kWh they cost $0.27 per running hour, or about $9.45 for five hours a day over one week
Oil-filled radiators
These use an electrical element that is submerged in a reservoir of thermal oil situated inside the appliance to create heat when it is switched on.
Oil-filled radiators are a type of electric inertia heater, which means they accumulate a lot of heat when they’re on, which is then stored inside itself and will continue to heat the room after it has been switched off.
The maximum power setting on an oil-filled radiator will use about 1,500 watts, costing $0.27 per running hour at $0.18/kWh, but most modern models will feature a low power setting that will use between 600-700 watts.
Convector heaters
Convector heaters are a type of indirect heating system. They work by sucking up cold air via the heating element at the bottom, which is then heated up before being pushed up towards the ceiling. This air then cools, drops down, and then the process starts again, it is a very efficient way to heat a room.
If low energy consumption is a priority for you, then a convector heater is a great option. Using around 1,500 watts of electricity each hour it will cost around $7-$10 per week to run over short to medium periods of time.
Fan heaters
Good fan heaters can almost instantly heat a room! Large volumes of air are quickly pushed through the heating element using a built-in fan, sometimes with the ability to oscillate 180 degrees. Most fans also allow you to switch the heating element off to perform like a conventional fan.
Fan heaters are ideal for areas where quick blasts of heat are required, rather than having to consistently maintain a specific temperature. Fan heaters can be mounted onto walls, stand on the floor, sit on desktops, or be incorporated into ceiling fans.
Not necessarily the most cost-effective choice, fan heaters use around 2,000 watts of electricity per hour and will cost about $0.36 per running hour at $0.18/kWh. However, given the fact they’re designed to be used in short bursts, it is still an affordable way to heat a room.
Halogen heaters
Halogen heaters use a halogen element within their heating bulb and lamp – the halogen gas increases the efficiency of the heating element.
Unlike the other types of electric heaters we’ve featured, halogen heaters use halogen gas to produce radiant heat which is very effective at heating small spaces rather than whole rooms. They are lightweight, portable, and relatively cheap to run when compared to other electric heating systems.
Halogen heaters usually feature multiple heat settings, each using a varying amount of electricity per hour – 400, 800, and 1,200 watts. At $0.18/kWh, 400 watts costs about $0.07 per running hour, 800 watts about $0.14, and 1,200 watts about $0.22.
Storage heaters
Storage heaters are a type of electric heater that are usually installed in houses that have no direct access to mains gas. In a nutshell, they charge up overnight, warming up thermal heating bricks that are situated inside the unit, ready to release the stored heat during the day.
Storage heaters offer the best electric solution at the lowest price, as they use energy during times the prices will be lowest. They can be used as a standalone system or installed as a supplementary option to be used in conjunction with another heating source.
Storage heaters are available in a range of sizes from between 2 and 7 kilowatts and typically use 2,500 watts per hour. However, because they use this electricity overnight when the cost of electricity is at its lowest.
Infrared panels
Infrared light isn’t visible to the naked eye as it is beyond the spectrum humans can see. An infrared heater uses light that is invisible to our eyes to heat us by being absorbed into our skin and clothes – it’s the equivalent of sitting in the sunlight as opposed to sitting in the shade – you feel warmer in the sun because the light that is hitting you is being absorbed, but when you’re in the shade the light can’t reach you as well.
Infrared heaters consume less electricity than some other heating units and usually require no more than 1,500 watts of electricity to run at a cost of around $10 a week when used regularly.
Electric underfloor heating
If bulky heating systems aren’t right for your house, then you might want to consider electric underfloor heating. These radiant systems produce heat by heating the floor rather than the surrounding air, and this heat rises up to help warm the entire room. Underfloor heating is a cozy and comfortable way to heat a home as it maintains a steady and even temperature throughout.
It costs around $10 to $15 per square foot to run and is cost comparable to a washing machine or dishwasher.
Summary
Thankfully the days of electric heaters being both expensive and aesthetically displeasing are well and truly over! Today’s ultra-modern, energy efficient, environmentally friendly, and stylish electric heaters offer discerning consumers huge amounts of choice.
Do not assume that one fuel will always be cheaper. Compare current local tariffs, equipment efficiency, installation cost and the heat demand of the building before choosing a system.
FAQs
How much does it cost to run an electric heater for a month?
The answer to this question all depends on the type of heater you are running and the cost of electricity in your state. However, as a guide, a 1,500–2,000-watt electric-resistance heater running for eight hours a day costs about $64.80–$86.40 over 30 days at $0.18/kWh. Use your own tariff and actual running time for a realistic total.
Is electric heat more expensive than gas?
Comparing electric heat and gas heat is challenging as they are billed in different energy units – electricity is in kilowatt hours and gas is in therms. The answer depends on local tariffs and equipment efficiency. Electric resistance, heat pumps and gas furnaces perform differently, so compare the delivered heat and whole-system costs rather than the billed units alone.
What costs more to run, AC or heat?
There is no universal answer. The result depends on climate, thermostat settings, building insulation, local energy prices and whether the heating system is electric resistance, a heat pump, gas or another fuel.
