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.

This is important because having a room size that is too large compared to the capacity of the heater would result in inefficiency, i.e., it would have zero impact on the temperature level of your home, and it wouldn’t be due to the poor quality of the device as it wasn’t designed for such purpose.

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.

What is the best type of space heater for the large room: electric or oil heater

The electrical and oil type heater carries out the same function of heating a space, and I would say efficiently, but it still depends on the models in question.

These two units, however, does their job in an entirely different fashion, as the oil heater makes use of fins consisting of hollow columns containing oil.

The oil is heated using a heating element powered by electricity or a flame, and the heat it releases is circulated the home by the fins. On the other hand, the electric heater doesn’t make use of liquids but instead depends on electricity to heat metal columns and then to blow the heat generated out using a fan.

Electric heaters generally heat up more quickly than the oil type and have bodies that are cool to touch while it is in operation, unlike the oil heater that heats up itself as much as it does the environment. Be sure of burns if you come in contact with it.

Electric heaters though should be used with high consciousness, as it could be dangerous if it comes in contact with water, causing shocks and have been known to burn materials placed directly at the front of its heat outlet.

In conclusion, electric heaters are the better type due to its natural safety condition to keep to, don’t use it in bathrooms or spill water around, and of course avoid kids from putting their hands in the outlet, and you would be fine. It also heats up the room faster and more efficiently than the oil type.
