Space heaters use 500-1500 watts of electricity, depending on size and type
Space heaters are a popular choice for many during the winter months, but they can be energy-intensive. The power consumption of a space heater depends on its type, size, and power rating. On average, a space heater uses 1,500 watts of electricity when running at full power, but this can vary from 500 to 1,800 watts depending on the heater.
The amount of electricity a space heater uses over time is measured in kilowatt-hours (kWh). The formula for calculating kilowatt-hours is watts x hours used/1,000. So, for example, if you use a 1,500-watt space heater for eight hours a day, that's 12 kWh per day.
The cost of running a space heater will depend on your local electricity rate. Using the national average of 16.62 cents per kWh, running a 1,500-watt space heater for an hour would cost around $0.25. At this rate, using a space heater for eight hours a day would cost around $1.96 per day, or about $51.65 per month.
To ensure your space heater is as efficient as possible, it's important to choose the right size for the room you want to heat and to make sure the room is well-insulated. Using a timer or setting the thermostat correctly can also help minimize energy usage. Space heaters are most energy-efficient when used to heat small, confined spaces.

They can be energy-efficient if used intentionally, especially in small spaces
Space heaters are a convenient way to heat your home during the cold winter months. However, they can also be a significant drain on your energy usage and electricity bills. The average space heater consumes about 1500 watts of electricity, with some models ranging from 500 to 1800 watts. This amounts to 1.5 to 1.8 kilowatt-hours (kWh) of electricity consumed per hour of usage.
While space heaters can be energy-intensive, they can also be energy-efficient if used intentionally, especially in small spaces. Here are some ways to ensure you're using your space heater efficiently:
- Use the lowest setting: Adjust the thermostat to the lowest comfortable setting. This reduces unnecessary heating and energy consumption.
- Choose the right heater for your space: Ensure your heater is properly sized for the room you intend to heat. A heater that is too small may struggle to heat the space effectively, while a heater that is too large may consume more energy than necessary.
- Insulation: Make sure the room you are heating is well-insulated. Proper insulation ensures that the heat generated by the heater is retained in the room, reducing the need for continuous heating.
- Timer: If your heater has a timer, set it to turn off automatically after a certain period. This prevents the heater from running continuously, allowing you to only use it when you need it. If your heater does not have a timer, you can manually turn it on and off as needed.
- Energy-saving modes: Many modern space heaters come with energy-saving (ECO) modes or similar features. These modes allow the heater to operate at lower wattage, reducing energy consumption while still providing some level of warmth.
- Targeted heating: Space heaters are most energy-efficient when used to heat small, confined spaces. Rather than heating your entire home with central heating, consider using a space heater to target the room you are currently occupying. This way, you avoid wasting energy on unoccupied rooms.
By following these guidelines, you can make informed choices about your heating options and manage your energy consumption more efficiently during the colder months.

The cost of running a space heater depends on your local electricity rate
Space heaters are an essential source of warmth during the winter months, but they can also be energy-intensive. The amount of electricity a space heater uses depends on its size, model, and power rating. Most space heaters use about 15 amps and connect to a 120-volt outlet, with an average wattage of 1,500 watts. Some heaters may use slightly less, with a range of 500 to 1,500 watts, while others may use up to 1,800 watts.
To calculate the cost of running a space heater, you can use the following formula: watts x hours used per day / 1,000 x local electricity rate. For example, if you use a 1,500-watt heater for eight hours per day and your local electricity rate is 16.3 cents per kWh, the calculation would be as follows: 1,500 watts x 8 hours / 1,000 x $0.163 = $1.96 per day.
To save on electricity costs, you can use your space heater strategically. This includes using it only when needed, setting it to the lowest comfortable temperature, and choosing a well-insulated heater with energy-saving features like timers and eco-settings. Additionally, consider using community solar or installing your own solar panels to offset some of the costs.

PTC heaters consume less electricity and can be used with solar power
Space heaters are an essential source of warmth during the cold winter months, but they can also be energy-intensive. The average space heater consumes between 750 and 1500 watts, with some using up to 1800 watts. This can add up to a significant amount of electricity, especially if the heater is used for extended periods.
PTC heaters, on the other hand, are designed to be energy-efficient and consume less electricity than traditional heaters. PTC stands for Positive Temperature Coefficient, and these heaters operate by utilising a ceramic element that increases in resistance as the temperature rises. This means that PTC heaters self-regulate and maintain a constant temperature, which can lead to reduced electricity consumption. Additionally, PTC heaters are equipped with a thermal cut-off switch that turns off the heater when it reaches a specific temperature, making them safer than normal heaters, which can be prone to overheating and causing fire hazards.
The energy efficiency of PTC heaters can be attributed to their ability to wait for heat transfer to occur before drawing more electricity. Once they reach their maximum temperature, PTC heaters consume 0 watts, whereas standard heaters continue to consume electricity to maintain their wattage. This makes PTC heaters ideal for use with solar power, as they can utilise solar energy during the day and conserve electricity, resulting in potential cost savings for the user.
A user on Reddit reported success with this method, stating that their PTC heater ran for 6-7 hours a day on solar power. They mentioned having 2300-watt solar plates and a 2.5kW inverter, allowing them to adjust the settings on their PTC ceramic heater to consume around 400-450 watts. This setup is suitable for a small group of people in a room.
While PTC heaters offer advantages in terms of energy efficiency and safety, it is important to consider the upfront cost. PTC heaters tend to be more expensive than normal heaters, making them a more significant investment. However, their long-term energy savings and safety features may outweigh the initial cost for those prioritising efficiency and peace of mind.

Heat pumps are more efficient than electric heaters as they use outside thermal energy
Electric heaters are a popular choice for many, especially during the winter months. However, they can be energy-intensive, with power consumption ranging from 500 to 1500 watts, or even 1800 watts in some cases. The cost of running these heaters depends on the local electricity rate, and it can add up quickly, contributing significantly to the monthly electricity bill.
Heat pumps, on the other hand, are a more efficient alternative to electric heaters. They use outside thermal energy, moving heat from one place to another, and often provide more heat (in watts) than the electricity they consume. This efficiency is known as the Coefficient of Performance (COP), which is about 1 for electric heaters but 2 or higher for heat pumps.
The higher efficiency of heat pumps means they can significantly reduce electricity consumption and costs. For example, producing 12,000 Btu with electric heaters would require 2.5 devices running for a total of 2,700 kilowatt-hours of energy per month. In contrast, a heat pump could achieve the same output with only 648 kilowatt-hours of energy, resulting in much lower costs.
Additionally, heat pumps can be even more efficient in the summer months, using less than half the energy required for heating to cool your home. They are also safer, with no off-gassing or carbon monoxide risks associated with fossil fuel heating. While heat pumps may have higher upfront installation costs, their operating costs are lower, making them a cost-effective and efficient choice for heating and cooling your home.
In summary, heat pumps offer a more efficient and cost-effective solution for heating compared to electric heaters. By utilising outside thermal energy, heat pumps can provide more heat output while consuming less electricity, resulting in lower energy bills and a more comfortable home.
