The ambient temperature of the surrounding air plays an important role in human comfort. A temperature range between 20 to 25 degrees Celsius is ideal for humans. Various devices are used to control the temperature of the surrounding air. The space heater is used to keep the ambient temperature comfortable for colder seasons.

A space heater is a good alternative to centralized heating systems. It is a compact device that offers air heating by convection or radiation process. The low-wattage units offer heating with minimal energy consumption. Before buying a unit, the user must be aware of several factors affecting a space heater’s performance.

  • Wattage: Wattage plays an important role in heating the surrounding air. With a good wattage rating, the space heater delivers better temperature output. The low-wattage space heaters are usually rated for low-wattage, but it still does the job. These units are available in 200 to 500 Watts variants.
  • Room size: It is important to consider the size of the room where the space heater will be installed. Every space heater offers a certain coverage area, which offers better heating. The low-wattage space heaters are ideal units for smaller rooms and office spaces. Most of these units can be used for a room of size between 100 to 250 sq. ft.
  • Heating method: The heating method for a low-wattage space heater might vary, depending on the unit type. In convection heaters, heat is passed through the mediums like air which automatically circulates to the colder air. For radiation-based haters, the heat directly heats the intended areas without needing a medium. Most space heaters use convection, forced convection, or radiation.

Buying Guide For The Best Low Wattage Space Heater

The low-wattage space heaters are cheaper and more efficient alternatives for space heating. These units consume less electricity and offer better heating of the room. Due to the lower wattage rating, they are also safe against electrical hazards. A list of these space heaters has been discussed already. Before moving on, we must be aware of certain parameters that govern the space heaters’ selection process.

1. Wattage

The heating process of a space heater is totally dependent on its wattage rating. In simple terms, the wattage is the measure of how much electricity is being consumed by the heater. Since it controls the heating output, it is considered a critical factor for low-wattage units. A higher rating delivers better heating at the cost of increased power consumption. But in the case of these heaters, the heating requirement is low, and thereby lower ratings are given preference. Several units are available with wattage ratings between 200 to 500 Watts.

2. Room Size

The overall coverage area of a space heater is given equal importance. Every low-wattage space heater has a recommended coverage area. The room size must be small or equal to their coverage rating to ensure efficient heating. The space heaters are suitable for smaller rooms sized between 100 to 250 sq. ft. The suitable room size also depends on the wattage rating of the space heater. Hence, a higher-wattage unit will eventually heat up a larger room.

3. Heating Method

The heating method is crucial to transfer the heat to the air effectively. There are various types of heating methods used by low-wattage heaters. Convection, forced convection, and radiant heating are the most popular heating methods. In convection, the air is heated circulation naturally through the room. Natural circulation is a slower process, so components like fans are used for forced convection. Radiant heating does not require any medium to transfer heat. The users can feel warmth by simply standing near these units.

4. Noise Level

The space heaters usually operate silently without creating a noticeable noise. The source of noise, however, depends on other components. For forced convection, a fan is used to blow the heated air. This fan causes certain levels of noise when running at higher speeds. Similarly, heating elements also create noise whenever the heater is switched on. The overall noise of a low-wattage space heater matters when used overnight, as it might interrupt the user’s sleep. These heaters are designed to produce noise output below the 45 dB limit.

5. Safety Features

The space heaters are equipped with several safety features to keep users from burning or electrocution hazards. One of the most popular features is the tip-over switch. It turns the heater off whenever the body of the heater is tilted too far. This helps in preventing fire accidents. Overheating protection and automatic shut-off features are quite similar, where the temperature is monitored. The space heaters are also tested and tried with certain safety organizations like UL for the user’s safety.

6. Warranty

There is never a guarantee against accidental damages, even if the space heater is high-quality. Hence, various brands offer a warranty over their space heaters to ensure repairs or replacements. The warranty period also assures the user about the product’s quality. The warranty might be available for the fall product or certain components and repairs. The space heaters usually come with 1 to 3 years of warranty. Some bands also offer additional warranties over their products, which the users can avail of.

Low Wattage Space Heater – FAQs
