What are the most important things to consider when buying a space heater?

The most important thing to consider when buying a space heater is the size of the room. Micro or personal heaters are usually great for office spaces or smaller rooms. They use less energy and heating the surrounding air will contribute to feeling warmer in minutes.

Many even offer safety features like overheat protection, tip-over switches, and cool-touch exteriors. However, they tend to be more expensive than other types.

A unit that is great for larger rooms would be a fan-forced heater. They can heat up to 400 square feet and are perfect for medium-sized rooms, basements, or garages.

It generally makes use of convection heating which sends the surrounding air through an electric filament causing it to heat up rapidly. This is a more cost-efficient type of space heater and will be less expensive than personal heaters.

Cabinet heaters are another option that can work well in larger spaces, but they use radiant heating which sends out infrared rays to heat objects closest to it.

You need to have some clearance from furniture or any objects near it because they will get very warm. This type of heating is the most energy-efficient, but they are usually rather large and can be heavy making it difficult to move them.

Thermostat Control:

A great feature of many modern space heaters is thermostat control. They let you adjust the temperature depending on your comfort level without having to manually change the settings every time.

Safety Features:

Other safety features like overheat protection and tip-over switches can come in handy as well. Many units also have an automatic shut-off feature, but they can take a minute or two to react so it’s important to unplug the unit when you leave the house for extended periods of time.

Is it safe to run a space heater all night?

Taking the following necessary precautions into consideration, yes it is safe to run a space heater all night.

Smoke Detectors:

You must install smoke detectors throughout the house and make sure that the sensors are cleaned regularly with compressed air. 

Gas/Propane Heaters:

The use of gas/propane heaters could be hazardous if using it without the installation of Carbon Monoxide Detectors which is an odorless and colorless gas that kills hundreds of people around the world every year. 

Direct Plugging:

Always plug your electric personal space heater directly in the wall. The use of extension cords or other supporting material is NOT RECOMMENDED, as they can overheat and can cause burning. 


Always place the personal tower heaters on the floor and never on the table or any other furniture, because it can tumble and can cause burn and damages to valuables. 

Good Distance:

If you are using forced air, radiant or gas heaters, make sure that the heater is at a safe distance from any flammable objects like curtains etc. if it is a radiator or oil-filled heater, that can be placed within one foot space from wall but even these heaters must be kept at a fair distance from flammable objects.
