Unlike many families who have a central heating system at basement or large apartment, you may only need just a good space heater for your large room. But with so much variety of brands in the market with different specifications and efficiency, you may find it difficult to pick the best heater for large space. Which is why we have taken our time to select each of them and review after testing

What is the best type of space heater for large room?

There are so many products in the market to consider when choosing the best space heater for large rooms, ranging from the type of rooms, the people occupying the rooms, e.g., kids or pets, and other additional safety features.

Before shopping, you should also know that the larger the room you plan purchasing the best electric heaters for, the larger the size and power of the space heater to consider.

According to the mode of heating, the three main types of heaters for large rooms are

  • Radiant Heaters:

These heaters Work just like solar radiation in such a way that it makes use of gas, electricity or fuel to generate heat. Hence, most of the radiant heaters are infrared models, and these heaters work to warm rather than heating a whole room. In most cases, they are pointed towards a specific direction.

  • Convection Heaters:

These set of heaters work by creating air circulation that is actually hot rising air. Therefore, it makes it easy for convection heaters to heat a whole room

  • Combination heaters:

Space heaters like the ceramic radiant heaters combined both radiant and convection to heat a specific direction and a whole large room.

According to the mode of design, there are four major types of space heaters for drafty rooms which are:

  • Electric fireplace heaters
  • Freestanding heaters
  • Wall heaters and
  • Baseboard heaters

Qualities to consider when choosing the best indoor electric heater for drafty rooms

The following are vital attributes that should be examine in any heater for large rooms

  • Safety:

This is more important than any other consideration irrespective of how urgently you need to heat your room. Before installing your electric heater, you might want to check if it was tested for safety first. This can be done by checking for safety labels like Intertek, Underwriters laboratories etc.

Some other safety features you may want to check by yourself is the cool touch exterior feature and the tip over which triggers the automatic switch off function.

  • Size and power:

Size of the indoor electric heaters is one of the most important factors you might want to consider before purchasing. First, it dictates the space that would be occupied, and secondly, it shows how powerful the heater is; because big size heaters have been known to be more powerful than the portable one.

Depending on the room size, you should go for a space heater with the capacity to properly heat the large room. Purchasing a very large space heater for medium size rooms could do more harm than good in the long run.

Typically, space heaters with 10 watts will heat a 1sqft room. Therefore, you might want to consider a heater a unit of about 50-100 watts for a room of 7sqft.

  • Installation type:

There are just two types of large room space heaters according to installation type. There is the one that is mounted permanently in the room after purchase, once installed it cannot be moved around.

The other type is just put in a safe space in the room and allowed to do its job. If you don’t want to move your heater and plan on keeping it in one place i.e. permanently installed, look for the one with an oscillating fan to distribute heat, it is also recommended for rooms with high ceilings.

For portable heaters that are not permanently mounted on a wall, there is more chance of stumbling over it especially when you have kids or pets in your home, which is really dangerous.

  • Mode of operation:

Some of the best space heaters for large rooms operate automatically, i.e., when the room begins to overheat it automatically turns off, and for some others, the desired temperature would have to be selected manually by the user. Although the automatic heater is preferable but it is more expensive.

  • Heater type:

There is the conventional heater that passes electricity through a heating element, causing the heating element to become hot, some of them include a fan, for example, oil-filled space heaters. There are also the infrared heaters that radiate heat through infrared rays that transfer heat directly to a solid surface and not the air.

The convection heater with a fan warms the room more quickly than those without fans, the ones without fans warms the room slowly because the heating element is surrounded by either oil or water which must be heated first. The risk of fire is lower with oil-filled filters than those with fans. The radiative heaters is suitable for warming people in poorly insulated rooms or outdoors.
