What size is considered a large living room?

Before you go out there to purchase a heater for your home, it is essential you know the exact size of your room to understand what size classification it would fall into, whether small, medium or large.

On the other hand, you shouldn’t have a large-size large-capacity heater, mounted in a small room, as this would have an adverse effect, excluding the apparent option of it cooking you up literally.

A living room is tagged small when it falls around the dimensions 10 x 13ft, which is equivalent to 130sqft and can be stretched to a maximum of 200sqft.

Medium sized rooms are considered around 12 x 18 feet, which is about 216sqft and can be extended across places of up to 300sqft.

15 x 28ft Sized from 300sqft upwards can be regarded as large rooms and you should purchase a heater for it accordingly, you wouldn’t expect a 500sqft rated heater to serve your 1500sqft because they both fall under the large room capacity, would you?

What is the relationship between room size and heating temperature?

The size of the room most times have a direct relation with the heating temperature. For small bedrooms, attaining a temperature of about 25 degrees, for example, might seem very hot, not because 25 degrees is hot but because of the confined space, it is in.

While in larger rooms, it is more challenging to achieve higher temperatures because the heat is distributed across a more full area, hence limiting its overall impact.

Overall, the larger the room, the more the amount of heat (BTU) required to raise the temperature level, while for smaller rooms it is much more easier to heat with small BTU.

While heating an ample space, the speed at which the desired temperature is attained also depends on the size and capacity of the space heater in use.
