Savings using a space heater for 8 hours per day Those with electric heat save less -- about $72 respectively -- and folks with natural gas, which is currently cheap, would pay about $36 more than if they ran a space heater.
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.
The amount of savings depends on various factors, including the heater's energy efficiency, the room size, and your local utility rates, but it can range from a few dollars to significant savings in colder months.
Really, it all depends what kind of heater you're looking for and more importantly how you use it. It's also important to note that, if used for over long periods of time, electric room heaters can be expensive to run (as electric is more expensive than gas).
As electricity is expensive, they are not a good option to heat your entire property, all day. However, if you are only heating one room, for 1-2 hours, they are very convenient, relatively fast and compared to the cost of heating your whole property, relatively cheap.
Electric heaters of any type are unsafe to leave running overnight because they carry a significant amount of risk. If a space heater falls over or becomes too hot from running for too long of a period of time, that can lead to a fast-moving fire that occurs while you are asleep and cannot act fast enough.
One advantage of space heaters is their lower upfront cost compared to central heaters. However, it's essential to consider the energy consumption and operating costs over time. Space heaters tend to be less energy-efficient and may consume more electricity or fuel to generate heat.
1. Gas boiler. A gas boiler is still the cheapest way to heat your home when comparing various heating systems, especially when analysis the latest figures from Ofgem. As of December 2024, the cost of gas is 6.24p per kWh, a 10% increase on the previous quarter, and still higher year-on-year.
On average, you can expect to pay about 20 cents per hour to run a typical space heater that's 1,500 watts and can heat a standard room such as a home office or bedroom. If you run it for eight hours per day, you'll pay about $1.60 per day or $48 per month.
One small space heater plugged in 8 hours a day can add about $50 to your monthly electric bill. Space heaters are a great way to increase the temperature in one room for a short period of time, but keep in mind that they can be costly to run and will result in a higher bill.
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.
Example (you can use an electric heater running cost calculator below for different wattages/kWh prices): If we assume the price of electricity is $0.1319 per kWh, a 1,500-watt electric space heater will cost; $0.20 to run per hour. $4.80 to run per 24 hours (day). $11.20 to run per week (8h/day).
They can also be more efficient when you will be using a room for a short period because they save energy by directly heating the occupant of the room and the occupant's immediate surroundings rather than the whole room. Safety is a top consideration when using small space heaters.
At Night: If you choose to use your space heater overnight, it's best to limit its operation to 4 to 6 hours on a lower setting.
Everything you leave plugged into an outlet—appliances, computers, consoles, chargers, lamps, and more —draws energy even when not in use. Energy is not only converted for household use, it's also used by power suppliers.
Oil-filled heaters can be very energy efficient, especially for long-term use. Once the oil is heated, these heaters can continue to provide warmth even after being turned off, using less electricity overall.
The Energy Saving Trust , an independent organisation that provides advice on energy use, is unequivocal on this point. It says that keeping your heating on all day uses more fuel and so is more costly.
This shows natural gas is the cheapest type of heating to run and heating oil is the most expensive way to heat a home.
Electric heaters are 100% efficient at point of use as they convert every watt of electricity taken from the wall into usable heat, meaning there's zero waste. In this sense, all electric heaters do in fact have the same efficiency.
Generally, a space heater will use between 1,500 and 1,800 watts. That means that in one hour, it will consume 1.5 to 1.8 kilowatt-hours (kWh) of electricity. In one day, that equates to approximately 12 to 14 kWh.
Tubular heaters are the cheapest electric heater to run this winter, offering efficient heating at low operational costs. In this article, we'll explore various types of electric heaters—including halogen, oil-filled, fan, and tube heaters—comparing their energy consumption, performance, and unique features.
A single tea light heater is not enough to effectively warm a room. When a tea light burns, air pollutants such as Volatile Organic Compounds (VOC) and particulates into the room air and you have to ventilate more often.
Unlike traditional space heaters, many solar air heaters typically need to be mounted to a roof, wall, or window, in order to collect the sun's heat. Some of these collectors can be heavy and installation may require a building permit. The way they work is relatively simple.
