Efficiency of Space Heaters
Space heaters are devices designed to heat a room or a space. They can be electric, gas, or oil-powered. Many of them incorporate other heating methods like convection and infrared heating to ensure that the whole space is heated evenly.
Space heater efficiency can be evaluated in 3 different ways: its power consumption, cost per hour and the annual operating cost. The higher the wattage, the more electricity it will use for the operation. The average running cost for an hour might range from $2 – $10 depending on models and settings, which means that some units might not provide enough heating for longer periods of time. Lastly, the annual operating costs determine how much a space heater was used. Normally, the annual operating costs for a space heater ranges between $250-$350.
The most effective heating method depends on three factors: the size of the space to be heated, its layout and the climate. The more surface area you have to heat up (a larger room), the more heat can bounce off from walls or furniture and escape through open windows or cracks in doors. The climate is also a crucial factor and should be considered because some types of heaters may not work very efficiently in cold climates.
Types of Space Heaters
• Electric Space Heater
An electric space heater is usually plugged into an electrical outlet and can heat up a small room quickly. It tends to have the best efficiency and is the easiest to use. However, it should be used only for short periods of time because of overheating issues. Also, it is the most expensive type of heater.
• Infrared Space Heater
An infrared heater uses infrared radiation to heat a room. It is more efficient than a conventional space heater and it can heat a room or a whole house for about the same cost as an electric space heater. Because a heating element does not produce the heat, it doesn’t get hot enough to burn out or have hotspots, which will last longer and provide consistent use without any issues. However, the initial investment might be higher, so you might want to consider cheaper options before spending your money on it.
• Gas Space Heater
Gas-powered heating units are traditional than the other types but are still useful and efficient. They tend to be quiet while in operation and can easily heat a room or an entire house. However, they can often be bulkier than other units.
• Oil Space Heater
Oil heaters are almost as efficient as gas heaters, but they are considerably safer. They are not as popular in the industry because of their relatively high cost of operation and the need for special equipment to refill them with oil when their tank is close to running out. However, they are still good to use if you plan to use them for a period of more than 5 years.

Conclusion
Space heaters are one of the most efficient and practical ways to stay warm during the winter months. They are easy to use and come in a wide range of designs, making them perfect for almost any home or workspace. Whether you decide on an electric or gas unit, make sure that you do your homework and look for ones with good efficiency ratings before purchasing one.
Frequently Asked Questions
Q. Do I need a gas shutoff valve in my room/office when I use a gas space heater?
A. If you have a central heating system in your house or office, you won’t necessarily need one. However, if the heater is for a room with its own thermostat and/or separate ventilation system, it would be optimal to have one. It’s advisable to install it on an external wall close to the floor so that kids can’t accidentally turn it on or touch it. The valve should also be facing away from individuals.
Q. Where should I place my space heater?
A. For the most efficient heating and a longer life span, it’s best to keep your space heater within 5 feet of any heat source. If you’re using gas, make sure that you have a ventilation system in the room to get too hot.
