Ceramic fan-forced heater is a well-known choice when people think about space heaters. They can heat your room very quickly while giving you a number of great features, making this model desirable.

They offer various fan settings, so you can adjust the heat as you want. These heaters, moreover, has a ceramic heating plate ensuring a large amount of heat will be produced. The ceramic material also helps to improve the durability of the heaters.

The ceramic heaters are created with different designs and sizes. Therefore, they are perfect for medium and large space including your garage or your house.


  • Quick heating
  • Numerous optional features
  • Able to adjust the fan sp
  • Energy efficient
  • Durable and useful ceramic heating


  • The room tends to cool down fast when turning off the heaters


Different from fan-forced heaters, we have radiant and infrared heaters as the next option. They can radiate the heat to everything in the front. They do not heat the air, instead, they make the objects warmer.

Thanks to this working style, these heaters do not waste any energy. But you can only use them in the small rooms or wherever people are sitting very close to each other.


  • Fast heating
  • Heat the objects in the front instead of the entire room
  • Save the energy


  • Not suitable for large space


Baseboard heaters are one of the best choices when you need a safely mounted model. As a result, they are not made with the portability. They are mounted to the wall and release the warm air with the fan.

They tend to be longer than the other models. That is why they can heat the large room in a moment. By taking advantage of the thermostat, it gives you the choice to adjust the temperature.

With those families having children or pets, you can buy the electric baseboard heaters. They have the cool-touch feature ensuring that you will not get burned even when touching them during the running.


  • Quickly heat the space
  • Mounted strongly to the wall
  • Offer the cool-touch
  • Safe and durable


  • Not portable



Do you want to have a portable space heater? This matters when you want to use it in different rooms. Otherwise, you can purchase the baseboard mounted heater that is stuck on the wall of all times.


Regarding the comfort, I find the radiant and infrared space heaters better in this aspect. Fan-forced heaters are also good, but they are harsher in some ways. The radiant and infrared models excel at offering the natural feeling without drying the air.


Before actually buying a space heater, you should know the room size that you want to heat. For the large room, I will be on the side of the fan-forced heaters. They will quickly heat your room and start the air circulation very well.

In case your room is quite small with a few people, you should buy the infrared heaters instead of the fan-forced ones. This way can save you more money but still deliver effective results.


The space heaters, these days, allow you to use many power options. They help you adjust the heat accordingly while conserving the energy better.

However, there are still some models with a fixed power option for anyone not being interested in changing the temperature.


There are a number of different kinds of space heaters in the current market with different price ranges. So, you can easily choose the most suitable one for your budget. The price depends on your need. For instance, you want to buy a basic model or a heater with various great features.

You should also consider the running cost while using the heater. Especially, you should know that electricity is quite expensive. You, hence, should look for those models which are energy-saving. By doing so, you can avoid wasting your money.

Some people think that the more powerful the heater is, the better it will heat your room. It is not completely true. When you use an over-powerful heater, it tends to overuse the heat that is not necessary at all.



When compared with the other models, space heaters are considered quite affordable to buy for household use. They are easy to install. On top of that, you can reduce the cost of your monthly heating bills.

Just imagine how expensive it is to set up a central heating system at home. I have calculated the cost and it seems to double if you compare with a space heater. You usually need to heat only one room at one time, so having a space heater brings you more benefits. Instead of heating the whole house, warming up one room each time will save you more money.


Many people emphasize the importance of portability. They like moving the space heater from one room to another one for everyday use. Thus, portability is one of the plus points making you buy this item.


Space heaters are designed with diverse safety features grabbing your heart. For example, you can seek some models that offer anti-tip protection. This feature automatically works whenever it feels like not being in an upright position.

On the other hand, I love the low-oxygen level sensor in some products. When the level of oxygen inside your room drops significantly, the heater will instantly turn off to keep you safe.


Running the space heaters at night is not a problem for anyone feeling irritated with noise. Most of the models run very quietly without giving you any interruption during your night sleep.


Space heaters are excellent at giving you a chance to control the temperature. It means that you can adjust the fan speed to suit your demand. With some advanced models, you can even have the remote control. As a result, you can just sit on the sofa and change the temperature as you want.


All in all, I think that you have already understood why space heaters are more and more favorite these days. Well, you can also choose the best space heater for large room on your own.

I personally fall in love with Lasko 5409 as it is extremely portable. Especially, the cool-touch design lets me feel free to carry it without worrying about the heating issues. This product also excels at controlling the heat to every corner of your room thanks to the fantastic internal fan operation.

Many of my friends also have the same thoughts as me. What is your favorite item in this list? If you need any more advice or instructions, please do not hesitate to keep in touch with me anytime.
