When it comes to finding the best space heaters, there’s a range of choose from. A handful of the options we’ve listed below can be used outdoors, and rival even the best patio heaters (opens in new tab). Plus, some of the models we have reviewed, like the Dyson, not only heat the room but take the allergens out of the air too. A quick look at our space heater reviews and you’ll notice that the handy heaters can be powered in two main ways. You can buy both electric and propane space heaters. Propane space heaters provide consistent heating without the temperature dropping. But they are known for depleting the amount of oxygen in the air. While electric space heaters heat up quickly and are perfect for indoor-use. In your search for the best space heater, make sure you check out all the features of the compact heater. Note the size, power settings, and whether it has a digital timer. This feature means your heater will automatically turn off after your chosen set time. You’ll also notice some space heaters come with the added ease of a remote control, and many have an automatic shut-off feature should the heater topple over. In our opinion, the best electric and propane space heaters listed below will take the chill off any room. But finding the best heater for you depends on how much you are willing to spend.

This particular space heater offers two fan speeds – low and high – and the body is made from steel, with covered vents at the bottom.

6. Lasko 6462: Best value space heater
The Lasko 6462 has a unique design that allows it to oscillate 360 degrees, which means it can effectively heat an entire room without being repositioned. This 1,500-watt heater can heat most bedrooms, though it can take a while to heat the entire room, as with most space heaters. In addition to high and low heating modes, this model has a built-in digital thermostat that lets you set your preferred temperature. Lasko covers this unit with a three-year warranty, which is much longer than the one-year warranties most space heaters carry. The heater’s fan puts out about 62 decibels or noise, which is normal for this type of product. Its case is made of plastic, which makes the unit light and easy to lift. Although this space heater has many useful features, it’s missing a few things that would make it even better. In particular, it lacks a fan-only mode, which means you can’t use it during the summer to help you cool off. The Lasko 6462 also doesn’t have a tip-over sensor to turn the unit off if it’s knocked over. However, it does have an overheat sensor to prevent it from getting too hot. Lastly, this model doesn’t have a shut-off timer. The built-in thermostat can perform a similar function, but it’s no substitute for an actual shut-off timer. It’s an older model, now, but we still think the Lasko 646 is excellent, and deserves a spot in our best space heater guide.

How to choose the best space heater
Not sure where to start when it comes to choosing a new space heater? Here’s what you need to know… The different types of space heater Energy Source Space heaters come in two main types: electric and propane. Electric models are the best choice for indoor heating and don’t require you to buy any fuel canisters. In contrast, propane space heaters are better suited for outdoor environments and are much more portable. Be aware that you shouldn’t use propane space heaters indoors without adequate ventilation to prevent the dangerous buildup of carbon monoxide. Heating power & energy consumption A space heater’s energy source, heating power and energy consumption indicate whether it’s powerful enough to warm a given space effectively. Electric models list power in watts, while propane heaters use British thermal units, or Btu. In general, you need 10 watts or 34 Btu per square foot in a room. This means a space heater rated for 1,500 watts or 5,100 Btu can effectively heat a room around 150 square feet. If necessary, you can convert watts to Btu to get a better idea of how much space a heater can heat. Multiply the watts by 3.41 to get a Btu rating. For example, a 1,500-watt space heater can produce around 5,100 Btu. However, remember that heating power and energy consumption are linked, so larger, more powerful heaters cost more to run than smaller ones. Safety Space heaters pose a higher risk for fire than a home furnace. Although these heaters are designed to sit on flat surfaces, their lightweight designs make them prone to falling over, which can put them in contact with flammable materials. For this reason, choose a space heater with a tip-over sensor that shuts the device off if it’s knocked over. The best space heaters also have other important safety features such as an overheat shutdown, which turns the unit off when it gets too hot, and a cool-touch exterior, which prevents accidental contact with the heating element. Some propane heaters have a feature called an oxygen depletion sensor, which turns them off before the volume of breathable air in a space reaches a dangerously low level. However, this isn’t a complete replacement for good ventilation and a carbon monoxide detector. Convenience features Choosing a space heater with a built-in timer or thermostat makes it easier to get the perfect heat settings for your needs. If the heater comes with a fan, as most electric models do, it can usually be used without the heating element to help cool you down during warmer months.
How Much Do Space Heaters Cost?
The space heaters we evaluated cost an average of $93, as we included some fancy models in our research. If you need something basic to keep a room warm there are many options available for around $50.
Tips for using your space heater
Here are some tips to keep in mind when using your space heater. By following these precautions, you can stay warm and safe:
Don’t set it and forget it: Space heaters aren’t meant to be left unattended. As such, you shouldn’t leave one running in an unoccupied room or use one while you sleep.
No extension cords: Space heaters tend to draw a lot of power, so it’s best to plug them directly into a wall. If you use an extension cord and it’s the wrong gauge, your space heater can melt the cord’s shielding and potentially cause a fire.
Give me some space: Space heaters are not clothes dryers. It is never safe to drape clothing or other items, especially if they are wet, on a space heater. This can cause the heater to overheat, short out and burn the items you set on top.
