There are several electric heaters for apartments on the market, depending on the room you intend using it for. From apartment to bathroom to basement, top portable heaters are designed to suit the needs of different places. Therefore you must know beforehand where exactly you want to use the heater.

The following qualities are to be considered before purchasing an electric heater portable for your medium sized room.

The product should also be portable enough not take up too much space in the room where it is placed, and if you fancy beautiful designs, then you might also consider the ones that are pleasant to the eye.

Heating technology:

There are several electric heating technologies used by different heaters. Some are excellent when heating the whole room while some do well in offering direct heat to individuals and objects in front of them.

  • Convection heating is the most common type of single room heating, and it works by passing convection currents across a heating element. The device also contains a fan that helps circulates the flows across the room. The main strength of this heater is that it warms up the whole room it is placed.
  • Radiant heating is the best for targeted spot heating because they radiate heat directly to the objects right in front of them and don’t really affect the air in the atmosphere.

We would advise you go for heaters that use radiant heating technology, as it is best for medium sized rooms. The main reason being that in medium-sized rooms, the number of individuals that live there wouldn’t be much, and this make is easy for the radiant heater to target the few persons around. Therefore you wouldn’t need to heat the whole space, unlike large rooms that are occupied by numerous individuals.


In small and medium sized rooms, you would need to be cautious as per the type of space heaters to use. Let’s talk briefly about the various space heater types, alongside their safe usage.

  • Ceramics Heaters: They make use of an internal ceramics heating element, and are capable of regulating their temperature without the use of wiring and coils to generate heat. The heating element does this by using its positive temperature coefficient for self-regulation, ensuring they operate safely.
  • Oil-filled heaters: It generates heat through the diathermic oil inside the radiator. The temperature is then dispersed into the atmosphere through radiation. The oil-filled heaters are most prone to fire, which could be a problem in medium rooms.
  • Infrared Heaters: infrared heaters use the transfer of energy to heat surrounding objects and people. The heating element could be a quartz tube or tabular heating element.

For medium sized rooms, it is best you go for ceramics or infrared powered heaters. They are efficient in operation and are less prone to fire for safety reasons.

Smart operation:

Best heaters are those that can automatically sense the atmosphere, operates and shuts off based on the current temperature level in the room. In a freezing atmosphere, it increases the amount of heat released, and when the atmosphere becomes too hot, it reduces the temperature.

A space heater with an automatic timer is what’s best for you, as you would not have to turn it on and off for convenience sake. Other smart operation features are: tip-over protection, energy saving modes, automatic oscillation, overheat protection switch etc.

Power Consumption:

it’s not just about purchasing a space heater, but you should also buy one that wouldn’t have a high cost of operation after already investing in the product. The amount of power usage is always indicated by the manufacturer in the product description page. You probably would want to see that before purchasing the product.
