Best Space Heater for Large Rooms

Heating large rooms can turn out to be expensive, especially if you are not careful when choosing your heater. Small heaters tend to heat slowly or overheat if used to in large rooms. Make sure you understand the size of the room you are going to heat before you buy a space heater. As a rule of thumb, 10W of power should cover a 1 square foot of space. Use that as your guide to help get the right space heater for your room.

If you prefer wall-recessed space heaters there are plenty of wall-mountable varieties out there. You can even go fireplaces that are aesthetically pleasing to complement to your house interiors design.

Frequently asked questions about the Best Space Heater for Large Rooms

Convection or radiant heat: what is the best technology for heating large rooms?

Convection heaters use air as their main medium of heat transfer from the heater to the different objects around the room. To heat up the room, air molecules in immediate contact with the heating element heat up and expand and this decreases their density. As they move away from the heater, they are replaced by more dense cooler air which in turn get heated up and the process of replacement is repeated until all the air is at the same temperature to that of the heater element.  

This makes them ideal for use in large enclosed spaces as the air can transfer heat energy to further parts of the house. 

Radiant heaters are useful especially when a quick heating solution is needed. They use infrared radiation to transfer heat energy to different objects in the house. They do not require an air medium to work. However, they can only work on objects that are in the field of view, and obstructed objects won’t be reached by the heat energy. They are useful in small areas like bedrooms and other areas where a quick heating solution is needed for short time.

Heating a large room with high ceilings: how to choose my space heater?

As hot air rises, using forced-air heating systems is sometimes less-than-stellar especially if you are dealing with a high ceiling. It may take forever before you can feel any heat change if you rely on convection heaters. 

To concentrate heat where it is needed most, it is time you committed to a radiant heating system. This will not only drive down the cost of heating during the frosty weather but also make sure you don’t remain cold while your system is still working.

Are large room space heaters energy efficient?

Most of the heaters on the market today are designed to be very energy efficient. However, the effectiveness of this efficiency comes down to whether you are trying to heat yourself or objects around you. You see, large rooms with poor insulation and high ceiling can be difficult to heat with convection heating solutions. Air is a poor conductor of heat.  

Radiant heaters, on the other hand, needs objects to be directly in sight for them to work effectively. They can be used to provide heat to people but are generally bad at heating large rooms.
