The arrival of winter also brings a drastic spike in our energy bills due to the excessive use of heating. A normal heater is said to use 1500 watts of power. Using such heaters can add up to your bill.

This is why it is best to use energy efficient space heaters. These are small appliances that are used to warm small rooms by consuming less power.

A good space heater uses around 750 watts of power. It can help reduce the energy bill by about 50%. Plus, space heaters are more affordable than central heaters and are also said to be easier to maintain.

However, buying an energy efficient space heater can be a bit daunting task as there are so many options on the market. To help you out, we have selected some of the best space heaters.

Let’s have a look:

The unit utilizes infrared technology that uses less power to do the job. It is an energy efficient option that can heat a large room in no time. It offers excellent heat distribution to ensure every corner of the room is comfortable.

Key Features:

  • Dual Heating System (Infrared Quartz tube and PTC).
  • Silent blower that produces high pressure.
  • Covers 1000 sq. ft. of space.
  • The thermostat can be adjusted between 50 to 86 degrees.
  • Tip over protection and auto shut off timer options.
  • The heater comes equipped with a quality blower that produces 250 degree F in only 3.5m/s. Thanks to it, this heater will heat up a room in a few minutes only. You will not have to sit in cold for too long.

    The blower works silently by producing a sound of only 39 dB which is said to be equal to a whisper. Hence, you won’t be dealing with an irritating sound even if you keep the unit operational for an entire night.

    You can choose between 3 power settings to run the appliance:

    1. Low Setting: It requires 1000W of power

    2. High Setting: It requires 1500W of power

    3. Auto Mode: It auto adjusts the desired temperature between 50-86 degrees F.

    These options are great. You can run the unit on high if the weather is extreme. Similarly, you use it on the Auto Mode to ensure you do not have to work manually. The unit will work according to room temperature and adjust output accordingly.

    There’s a digital thermostat on the heater as well that lets you control the temperature manually. You can also turn the heater on and off using it.

    Unlike standard heaters, this one uses infrared technology to heat a space. This technology is different as it heats up the objects in a room and not the air. Thus, the room retains air moisture and you won’t feel dry when this heater is operating.

    However, don’t let it fool you. It doesn’t mean the objects will be too hot to touch or anything.

    This space heater is super safe to use as there are no exposed heating elements. Hence, it doesn’t pose a fire hazard or any sort of danger. In addition to that, there’s also a tip over protection feature that makes sure the heater doesn’t overheat.

    You can operate this space heater with the help of an IR remote that comes with it. It will allow you to set a timer (12-hour), change temperature settings, etc.
