How did we choose?

  • The first thing we did was find 70 heater models with the best ratings.
  • The next step was to select 10 models for a detailed review. We excluded outdated or models with a small number of reviews. 
  • We analyzed around 120 customer reviews to highlight the most important criteria.

Thanks to this method we know which functions are the best at each model and which can be improved. You can see the results of our work below. 

Valuehunta® analysis methodology

What to consider when choosing a heater

  1. First of all, you should understand what type of heating method you prefer to use. Ceramic, radiant and infrared are considered to be the safest because they heat up without an open flame. Fan or forced air methods also do not use an open flame but they heat the air rather than objects in the room. That is why using them for a long period of time can cause a headache. 

There is also another method which we think is the most dangerous. It is propane heaters. They produce a lot of Carbon Monoxide that is why windows in your room should be opened almost all the time or you can suffocate. It is not so efficient, so we did not include propane heaters in our article. 

  1. As our research showed the most important thing is how powerful the heater is. To warm a large room you will need at least a 1500W heater.

All our selected models are powerful and have a lot of positive reviews about their abilities to warm rooms. The Homegear Compact 1500w Room Space / Cabinet Heater (review) stands out the most. This is not surprising as using 1500W this model heats the area up to 1800 sq. ft. Almost the same power has the Heat Storm HS-1500-PHX-WIFI Infrared Heater (review) but it cannot heat such a big room.

  1. The next significant feature is the automatic turn off which switches off the heater in specific situations. You will need it not only to maintain the adjusted temperature but also for your safety. Imagine that someone hooks on a heater and it overturns; there are interruptions in the power supply or the heater overheats. All these situations are dangerous as after a while they can cause a fire if the situation is not rectified. That is why automatic shut-off is something that you need to sleep calmly at night.

The Comfort Zone CZ442 Heater (review) is the best from this point of view as the automatic turn-off will work even if you accidentally knock the item. On the other hand, it can also be annoying that’s why we also recommend paying attention to the Dr Infrared Heater Portable Space Heater (review). This model is not so sensitive.

  1. The third point is slightly correlated with the second one. It is very convenient when you can adjust the temperature. Thanks to it you can choose the desired temperature and thus adjust the power of the supplied heat or the time periods when the heater will work.

The Dr Infrared Heater Portable Space Heater (review) has the easiest settings to adjust the temperature. For example, you can tune the desired temperature and the heater will maintain it during the whole night. The Amazon Basics Portable Eco-Smart Space Heater (review) is also among the easiest to control. It has just 3 buttons one of which is to adjust the temperature.

Additional factors to pay attention to

  • Fan — to inflate the heat.
  • Quietness — loud hum affects a person’s mental state.
  • Work without smell — we mean both the industrial and burning smell.
  • Reliable wires — in order not to be afraid that they will melt.
  • Casters — to easily relocate the heater.
  • Remote control — to adjust settings from distance.
  • Wi-Fi connection — a modern feature that facilitates the control process.
  • Small size — compact heaters are more aesthetic.
  • Durability — in some regions people use heaters every day so they expect that they will work well for a long period of time.

The Homegear Compact 1500w Room Space / Cabinet Heater is the best variant for those who need to warm extremely large areas. This heater is capable of warming the area up to 1800 sq. ft. It is the only heater on our list that combines a few heating methods. As the Heat Storm HS-1500-PHX-WIFI Infrared Heater (review) it uses radiant but in addition, it uses infrared and micathermic technologies. This model also has a fan. Unlike the Mudshi Portable Electric Space Heater (review) it does not use it just to heat the air but to blow warm air throughout the room. That is why using as all other heaters 1500 watts the Homegear Compact 1500w Room Space / Cabinet Heater can heat much larger areas.

Speaking about the increase of the electricity bill, some users complain that the bill came up by $60 but it is very relatively. You need to understand that it depends not only on the cost of the electricity in your state but also on how much time you use the heater during the day. To save money you can adjust the desired temperature. The heater will maintain it automatically turning on and off. This process is quiet and you will not even notice it.

Another feature is a built-in high-temperature sensor that will turn the heater off when it reaches an unsafe temperature. This is the protection from overheating. This unit has a built-in, stay cool carry handle with the help of each you can easily relocate the heater. But if you need to do it often, we recommend paying attention to the Amazon Basics Portable Eco-Smart Space Heater (review) that has casters. It is easier to roll the heater than to carry it.

This model is quite durable and can last about 4 years. But if you want to invest in the heater once for the whole life, the Comfort Glow BDISC6 Original Brown Box Ceramic Disc Heater (review) is ideal for you as it can work for 30+ years. One more advantage of the Comfort Zone CZ442 Heater is that it is small but powerful. With the same power as the Homegear Compact 1500w Room Space / Cabinet Heater (review) has, this one is almost half the size. That is why you can put it wherever you want in an 800 sq. ft. room.

  • Programmable timer (up to 12 hours)
  • Has overheat and tip-over protection as the Comfort Zone CZ442 Heater (review)
  • Certified by Underwriters Laboratories (UL) USA and Canada (independent testing laboratories)

Moreover, you can do all these with remote control. Also, you can program the timer and choose how long you want the unit to work (up to 12 hours). With these features, you do not need to control the heater every time you use it. You just need to set the necessary settings and you can go about your business.

  • 6 heating modes
  • Over-current protection
  • Has a handle at the back like in the Comfort Zone CZ442 Heater (review)

⛔️ Cons:

  • Cannot be set to a certain temperature but you can choose power and mode 

Being one of the smallest, the Mudshi Portable Electric Space Heater is designed to heat effectively both a large room and a trailer. The Comfort Glow BDISC6 Original Brown Box Ceramic Disc Heater has almost the same size but can heat a room not larger than the 600 sq. ft. As the Amazon Basics Portable Eco-Smart Space Heater (review) this model has 750W and 1500W heat settings to control the temperature. But this is the only model that has 6 modes: for 750W low, high, and only fan mode and the same for 1500W.

This heater has over-current protection to turn off the device when a larger than intended electric current exists through a conductor. In addition, like the Comfort Zone CZ442 Heater (review) this model has also tip-over and overheat protection. This model has a thermostat but the problem is that there you cannot set the desired temperature, you can only choose power and mode. But you can check the temperature (and in some cases humidity) with an indoor thermometer.

⛔️ Cons:

There is one disadvantage that some users complain about: it has a short cord. As with all heaters, you have to plug this one only directly into a wall outlet. You cannot use a heater with an extension cord. We recommend finding an outlet that you can use and free up space so you can put a heater nearby. Using 5200 BTUs or around 1560W this unit is the same power as others on our list and will warm your room without problems.

  1. I liked the Heat Storm HS-1500-PHX-WIFI infrared heater from your article. Does the fan blow the heat out well or is it weak? Bought heaters where the fan does not blow very well so don’t want that again.

  2. I LOVE Dr Infrared Heater Portable Space Heater! I made my bathroom into a heated yoga studio. I am an avid yoga practitioner and the heater help work perfectly. I wish it got a little hotter and the humidifier was a bit stronger but I have found if I run my shower really hot for a few minutes and add the heat and humidity to the enclosed space, it is wonderful.
