What should you look for in the best heater for large room?

A good heater comes with multiple features that can ensure your heater works well for your home and space. For larger areas, you need a strong heater that manages over a 1000 sq. ft. of space and is sturdy enough to withstand time.

BTUs of heat

The amount of heat your heat puts out will be in British Thermal Units (BTU). For larger rooms, you should look for a heater from 1000 up to 5200 BTUs. You should ensure you are purchasing a unit that is strong enough to manage the room or rooms you need to heat.

Heat rises, so if you have a second story, attic or high ceilings, any heat your heater produces will rise upward. A heater for a lower story or a basement, as any heat your heater will produce will rise upward, will require a stronger heater.

Temperature Control

Most types of electric heaters come with digital controls on the front of the heater that let you adjust the temperature up and down using arrow controls to move the settings up and down. You can use a remote control to adjust the temperature, but make sure there are manual controls on the outside of the heater.

Remote controls usually work at the onset but can fail after multiple uses. Most manufacturers can help with remote replacement, but if they cannot, you can still use the manual controls to keep your heater operational.

Noise Level

Not all types of heaters are quiet, so if the heater gives decibel levels (dB) for noise, you should consider how loud that will be. If you plan to use your heater at night in your room, make sure the noise level is not too loud for your sleeping needs.


Having a programmable heater can be a benefit if you need to leave before other family members in the morning or set a timer to have the heater turn off during the night to save energy. These types of units can help you set the timer for 1 up to 12 hour intervals depending on the time constraints you require.

Safety Features

Built-in safety features such as tip-over shut-offs and an outer surface that is cool to the touch are best for all types of home, but especially for homes with pets or small children. Pets and small children can touch or bump heaters causing the heaters to tip over or causing burns. The safety features can help your home stay safe as well as warm for even the smallest members of your household.
