Running your heater per day (8 hours): 8 hours X 13.9 c per kWh = $1.11/day. Using your heater for 8 hours a day per month: $1.11 X 30 = $33.3/month.
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).
An electric space heater is small but uses a lot of energy! A 1,500-watt heater running for eight hours each night for a month can add about $43 to your electric bill. Running multiple space heaters can run up your energy costs. Specific, sparing use.
Even though they are typically small in size, and often touted as 100% efficient, electric space heaters use a lot of electricity. Most space heaters use on average 1,500 Watts of electricity and cost about 15¢ an hour to operate.
For example, if you are running a space heater in your basement home office for 8-hours a day, then you can expect to pay $1.60 per day. If there are an average of 21-work days in a month, then you can expect to add around $33.60 per month to your electric bill to run your space heater.
The electric space heaters tested at Consumer Reports use 1,500 watts to fully power. Since you should never use a space heater while sleeping, it would cost $2.82 a day to use a space heater 16 hours a day, based on the national average electricity rate.
The Energy Department estimates that the cost to heat an entire home with electric space heaters cost 43% more than a gas furnace. Using a space heater in your bedroom only while you sleep is a practical way to use a space heater and won't make much of a dent in your electricity bill.
Most space heaters use 1500 watts of electricity per hour. However, there are smaller heaters too, starting at 200W per hour.
Space heaters do use less energy as compared to using central heat. However, they are not as efficient as space heaters. As such, having a space heater in every room in the home and turning them all on at the same will only cost you more, not less.
If your heater is equipped with a good thermostat and you do not heat the room to a warmer-than-normal temperature, you can save money by using an electric space heater in a room you're in and keeping the rest of the house chillier.
So I did the research, and even made a free calculator. On average, a 1,500W heater costs around $0.20 per hour to run on high. This adds up to a cost of $1.60 for 8 hours a day, and $48 per month. The running costs depend on your electric heater's power, running time, heat settings, and your electricity price.
How Much Does It Cost To Run Gas Central Heating Per Hour? If you use mains gas, you'll pay roughly 2.4p per kilowatt-hour. This means that if you have a 35 kW boiler, it will cost you around £0.84 to run it for an hour. However, if you use LPG, it can be a little more expensive.
According to research from Energy Helpline, keeping your radiators on all night will cost you an extra £10.80 a day. Over the course of a week, that would cost you £75.60, and if you did it all month you could be paying out a whopping £335.
Never leave your space heater alone in the room
The best way to prevent a fire is to never leave a space heater running in a room unattended—that way, if anything does go wrong, you can take action quickly.
In fact, the only way a portable electric space heater is going to help you lower your annual heating bill is if you use it to heat the room you're in and turn down the thermostat for the rest of the house.
So, basically, for every 1.5 kilowatts of heat, a space heater is going to need 1.5 kilowatts of electricity. A reverse cycle air conditioner needs approximately three times fewer kilowatts to generate the same amount of heat as a space heater.
Infrared Heaters – the lowest wattage per heat provided makes these the cheapest to run. Oil-Filled Heaters – their long-lasting heat makes the most out of the electricity. Storage Heaters – saves in running costs by using off-peak electricity tariffs.
According to the Energy Saving Trust, the national average price (as of November 2021) per pence/kWh of electricity is 20.33p. We have rounded it to 20p for illustration purposes. Electric heaters show much energy they use as their heat output. For example, a 2kW fan heater would cost 40p an hour to run on full power.
For example, a 1200 Watt halogen heater is the most common power output available in the UK. Often you can run them at 400, 800 or 1200 watts, so that would work out at: 400W = 6 pence per hour. 800W = 12 pence per hour.
Active solar heating may be the most efficient option for heating your home. Electric resistance heating can be expensive to operate, but may be appropriate if you heat a room infrequently or if it would be expensive to exte...
