What to Look for in a Smart Space Heater

Homes are getting smarter by the day. Now, we can lock doors remotely, view real-time feeds of security cameras, and even clean up after our pets via a robot mop. While some smart home devices seem gimmicky, having the ability to control a room’s heating is something that most households can use.

But we’re not talking about smart thermostats—we’re talking about smart space heaters that are conveniently sized to add the right amount of heat to a room when you need it.

Wi-Fi space heaters connect to your home’s Wi-Fi so you can control them via a compatible app on your smartphone. Some even offer voice assistant compatibility to heat a room using simple voice commands. Some of the best smart space heaters will even notify you when the desired heat has been reached so you can switch it off and save electricity.

Smart space heaters are designed to heat spaces without taking up much physical space. With all our devices in our daily lives, the last thing you want is a chunky electric heater taking up space.

So, consider the room you have, the features you want, and how much you want to be able to control your smart space heater, then dive into our recommendations below.

FAQ

Are space heaters safe?

Space heaters with the right safety features can help to create a warm living area without posing a danger. Choose a space heater with tip-over and overheat protection so that it will automatically shut off if there’s an issue, or notify you via your smartphone.

How much energy does a space heater use on average?

On average, most space heaters use around 1500W per hour. They are useful in situations where you need to heat a room quickly, but not particularly energy-efficient when using them as a long-term solution.

Can I leave a space heater on overnight?

Space heaters that feature a timer, eco mode (where the heater automatically switches off when the desired temperature is reached), and anti-tip/overheat protection can be left on overnight. While it’s preferable not to leave heaters on when you’re not in the same room, most smart space heaters shouldn’t be a problem.

Can I plug a smart space heater into a smart plug?

Most smart plugs should be able to handle the load of a smart space heater. While this might not be outwardly encouraged, it’s not dangerous to plug a smart space heater into a smart plug.

How do I reset a smart space heater?

Some space heaters will feature a reset button; others may need to be unplugged for over 30 seconds, then reconnected. If you’re having trouble connecting your smart space heater to its companion app, disconnect both the heater and your phone from the Wi-Fi, then try reconnecting.
