If you have been looking for a space heater to save money on your electric bill or just make a small living space a bit cozier, then the best low wattage space heater is perfect for you.
What to Look for in a Low Watt Space Heater
If you are shopping around for a low watt heater, you may be short on space. So compactness is something to keep an eye out for. And even though these types of devices are small, you should still use them carefully and opt for built-in safety features. In general, you should look for low watt space heaters that have:
- A compact design (no more than about 8 inches tall and 4 inches wide)
- Auto shutoff and tip-over protection features
- Wattage output of no more than 1500
- ETL (Electrical Testing Laboratories) listing or certification
Frequently Asked Questions about Low Watt Heaters
How many watts does a space heater use on low?
That will depend on the capacity of the low setting. As a general rule of thumb though, if you have a space heater that is running at 1,500 watts, it is consuming 1.5 kilowatts of power. 1,000 watts is equal to 1 kilowatt so if you have a space heater running at 500 watts, it is using .5 kilowatts of power.
What is the cheapest way to heat a room?
Portable convection heaters like the ones on our list are very economical.
Can you run a space heater all night?
You should always opt for space heaters with auto-shutoff functions like the ones on our list but even then, it is considered an unsafe practice to run any space heater while you sleep or unattended.
Low watt space heaters are a great option for when you want to make your personal space more comfortable. They don’t draw a lot of energy and some of them can even double up as fans when the temperature rises. Just remember that heaters of this size and capacity aren’t meant to heat your whole house. But if you choose the right one like these best low watt space heaters for personal use, you won’t be disappointed.
