Best Space Heaters in 2021


Does your room get a little too chilly than what you’d like?

Adding a space heater can help to make the room warmer and more welcoming. Space heaters make the most inexpensive supplementary source of heat for the indoors. Maybe you want a heater that can keep your bedroom warm and cozy throughout the night. Or, you want one for bigger spaces like the living room. This review of the best space heaters will help you find what suits your needs.

There are many models of space heaters in the market as manufacturers compete to provide the most effective room heating solution. The two most common types of space heaters are radiant and convection space heaters.

Radiant space heaters use glowing metal elements and a reflector to warm-up spaces. While they can warm the immediate area rather quickly, they take more time to heat up the entire room. This type of space heaters would work best as bedside space heating, for example.

On the other hand, a convection space heater pulls room-temperature air and warms it before redistributing it around the entire room. Some models have a fan that assists in the distribution of warmer air. The main advantage of adding a convection space heater is that it minimizes cold spots in the entire room. Besides, you can turn off the heater during hot seasons so that only the fan is left working.

Convection room heaters without a fan operate through conduction. They have a resistor that generates heat from electrical energy. Following this, a molecular structure spreads the heat until space is sufficiently warmed. For a user with allergies or even Asthma, a fan-less convection heater is the better option as it doesn’t dislocate dust or pet fur.

Once you are decided on the type of space heater, you can go ahead to consider other important factors. These include:

  • Size of your room: The best space heater for you should produce enough energy for the room. Generally, 1 square foot requires 10 watts of heat. Thus, if your room measures 100 square feet, then you need a 1000-watt space heater.
  • Energy costs: Considering the energy efficiency of a space heater is crucial in making sure that you don’t end up with an appliance that blows up your electricity bills. Pay close attention to features that enhance energy economy by reducing power usage. These features include energy-saving modes, programmable timers, and adjustable thermostats.
  • Safety: Like any other electrical appliance, a space heater carries the risk of fire. Reputable space heater models are designed with safety features such as automatic overheat protection and tip-over protection.
  • Noise level: You don’t want to sacrifice the tranquility of your space to get warmer.  Choose a space heater that doesn’t produce disturbing noise, especially if you want one for the bedroom or study area. A noise level of about 55dB and below is ideal for a quiet, peaceful environment.

Consider the following market-leading space heaters when you go out shopping.
