Buying Guide for the Best Space Heater

So many aspects come to mind when picking the perfect space heater for a 300-sq feet area, but first, you have to consider whether which type of heater you need:

Infrared Heaters

This kind of heater generates direct heat from infrared rays, so they are quick in heating the room. Besides that, they are silent workers and energy-efficient.

Convection Heaters

A convection heater is the standard kind, and it circulates warm heat in every corner, so they are an excellent choice for large rooms.
Convection heaters are available in a variety of types, and the most famous are ceramic heaters, which feature a fan that disperses warm air all around. On the other hand, these are a little expensive than infrared heaters.

Essential Features to Consider

  • Power Consumption
    Suppose your other electric home appliances consume less power. In that case, you need to get a space heater with the same power consumption capabilities.
    So, watt consumption counts, as you do not want to pay high bills.
  • Insulation
    Apartments with extreme insulations require fewer watts of power for heating. In comparison, rooms with less insulation require higher watts for heating.
    On the flip side, areas without insulation don’t demand a space heater at all because they are outside environments, such as garages, yards, etc.
  • Safety Features
    The most crucial factor to consider about a space heater is its safety for your home. Mini or big-sized space heaters are safe to use. Most models come with an overheat protection switch that automatically shuts the heater off when the temperature goes higher than expected.
    The best safety feature is regulation. With this feature, your electrical circuit and heater are safe from being damaged.
  • Ceiling Height & Square Foot
    A space heater works well with an 8-ft tall ceiling. Still, some high-end models easily cope with 9-ft tall ceilings as well.
    Usually, space heaters with 30% more wattage heat well under tall ceilings.
  • The Size
    When looking for the best space heater, considering its portability is an excellent way to make the right purchase. You don’t want to buy a large-sized heater for your mini room.
  • Noise Level
    Like most electric appliances, heaters emit a decent amount of noise while operation as well. However, robust and high-end models produce less sound than others.
    So if you want your room to remain as quiet and as warm as possible, prefer a non-fan space heater. Also, radiant space heaters are excellent in terms of noiseless operation for peaceful environments, such as offices and bedrooms.


Everyone looks the warmth and relaxing effects of a high-end space heater. It offers many benefits for your home in the winters, and it makes sure your body never exceeds cold temperatures.

You must have a lot of brain-wrinkling thoughts right now, but nothing is complicated once you consider our reviews. 

To ease it up for you, we have an excellent pick for you:

The Dyson Hot + Cool Jet Focus AM09 Fan Heater. It is safe, feature-filled, incorporates high-performance, and keeps you warm during chilly nights.
