How To Choose The Best Space Heater For Basement?
Power Output
To find out the right space heater that provides enough power to warm your room, you need to determine the area and the state of the room (including the type of power access available in the basement and the frequency of use of the heater).
Determine The Basement Area
Measure the length and width of the room (in feet), then multiply them together. The final number is the area of your basement (in square feet).
Facts: Each type of space heater has its own measuring unit of power output.
For example, gas- or propane-powered heaters are measured in British Thermal Units (BTUs) while electric heaters are measured in watts (W).
But they share one thing in common - the larger the number, the more powerful the system.
Basement State
Is your basement finished yet?
Has it been insulated yet?
What do you currently use the basement for? How often do you use it?
For an unfinished basement, you should install an insulation system into it before considering adding a space heater. Otherwise, you're burning your own money.
For a finished basement that is used frequently for a certain purpose, consider a powerful space heater to keep you warm while you're there. If your basement is rarely used, a gas wall heater or a portable electric model is fine.
Space Heater Types
The type of space heater impacts the way warmth is distributed throughout your basement. There are three common types:
- Fan-forced space heaters – the way they work is pushing heat into a room using a fan
- Radiant space heaters – which use gas or propane to warm people or objects in a room
- Convection space heaters – which heat up the air inside a room instead of warming people or objects. It’s best for an insulated room.
Power Input
When it comes to power input of basement heaters, there are two options: gasoline/propane and electricity.
Gasoline/Propane | Electricity | |
Pros | -Very cheap -Easy to buy | -Available in various sizes, price ranges, and styles -Not require professional installation & easy to install -Safe to use |
Cons | -Difficult to store -Combustible -> require the basement to be equipped with carbon monoxide detectors -Require frequent maintenance -Require professional installation | -Require a power outlet -Not as quiet as gas heaters |

How cold will a basement get with no heat?
A well-insulated basement might get down to 40 degrees F with no heat.
Does heating your basement keep your house warmer?
Yes, it does. Heating an insulated, unfinished basement does help keep the entire house warmer during cold months.
Should you keep heat vents open in the basement?
It's possible to close some basement vents. But to promote effective and consistent airflow in your home, it is recommended to keep the vents on other floors open while doing that.
And, after 1-2 days of shutting those basement vents, remember to reopen them.
Can you leave a space heater on all night?
If your heater has safety features like an adjustable thermostat, shut-off timer, tip-over protection, and auto-shutoff function, and is certified by one of the 3 main testing organizations, it is safe enough to leave the machine on all night.
