Review: Optimus H-1322 Portable 2-Speed Fan Heater

Optimus H-1322 Portable 2-Speed Fan Heater









  • The High Heat setting can actually be useful for heating up a small bedroom
  • Easy to use with just two dials to function this Optimus heater/fan


  • Fan setting is more like plain air, rather than cool air

When we’re dealing with small appliances, we usually think of them as not being nearly as strong as its larger versions. That is most definitely the case when you’re dealing with heaters as being small means that they usually are going to be using a smaller fan and overall, the power of personal heaters isn’t going to match large Tower types that are also very useful. That said, that’s not always the case and that’s because heaters have gotten better at providing more powerful heating for the past few years, and now even “Portable” or “Personal” heaters are capable of competing with larger ones if you know how to use them a certain way.

This Optimus H-1322 heater is the type of small portable heater that actually holds quite a good amount of heating power while it still maintains a small size. So let’s take a look if you should go with this small but powerful heater, rather than the Titans on the market that claim to be a whole lot more powerful and capable of heating a room.


Feeling the Heat:

With this heater, there are a total of three settings that you can place it on. The first one is the fan setting and it means exactly what it says, you can run this heater without the heat and so it’s can be used as a fan. That said, it’s more like plain air that’s being pushed out-out of the heater rather than cool air. We found that fan mode with this heater was very useful for circulating air around once you have heated up a room to your desired temperature.

Then moving on to the main part of this appliance, there are two heat settings. The Low heat setting with this heater has a  750Watt output and that’s 2,559 BTUs. While the high setting is double the Low setting as it has an output power of 1500Watts and that’s 5,118 BTUs. Each of the two settings has their place on when to be used.

Low Setting

When you combine the small size of this either, with its small fan along with the Low heat setting then it’s best to use it as a personal heater. The Low setting simply isn’t for heating up an entire room. Or at least, if you are heating up an entire room then it’s going to take quite a long time to do so as the heat is not hot enough; also the room that you’re heating up is going to have to be small too.

High Setting

Then there’s the high setting and this is where this heater is able to show its true prowess. As the fan does run a little faster on the high setting and the heat that’s outputted is even warmer. So with the high setting, you are actually able to heat up a room. That said, we highly recommend closing the door to the room so that the hot air is able to stay in the room and it can heat the room up faster. When it comes to heating up a living room, then this heater will not be able to do it. As a living room is simply too much of a large space and the heater lets out too little heat at once.

With the two heat settings, this heater also makes use of a thermostat. The thermostat doesn’t make use of any numbers on the Thermostat dial so you’re going to have to adjust the thermostat based on when it stops heating. So, yes, this heater does not stop once it has reached the set temperature and once it’s 2 degrees under the thermostat setting it will automatically turn back on.

Fuel Usage:

The power usage with this heater is pretty good as it has a small size. Using the high setting with this heater is fine and you won’t notice much of rising with your electrical bill. However, if you want to keep the change to your bill as minimal as possible then we recommend using the High heat for heating up a bedroom as fast as possible and then using the Low heat for maintaining the heat level within your room.


Functional Components:

It’s a very simple heater to use. Once you plug the 6-foot power cord in, all the other functional parts are at the front.

There are two dials at the front. The left dial is for the Thermostat, and when you turn it to the right, that turns the temperature up. The right dial has the setting for turning on the fan, Low heat, and high heat settings.

Once you do to have the heat on, there’s a red light that comes on at the front too, to show that the heater is on and running.

The noise of this Optimus-H heater is very low and even though you can hear a very faint humming sound from it, it’s basically nothing. We found that fan sound made for a pretty good background noise and was actually quite soothing.

Size and Weight:

This is a small heater and that might be one of the main reasons that you actually purchase it, as it’s not some tall Tower heater. It has a height of 10.5 inches, a width of 9.2 inches, and a depth of 5.5 inches. The weight is very light at 2.3 pounds only. Overall, owning this heater is going to be an easy experience as you can either place it on the floor or on a table easily and have it on either its Low or High setting.

There’s a built-in handle on the back of the heater that makes it easier to move around.


Structure and Material:

The entirety of the heater is made of plastic and even though this heater does have a high output of power, the outer parts of the heater stay cool to the touch. So there’s no need in worrying about the heater being hot when you go to touch it after it’s been on for quite a while. The functional parts such as the dials are okay, at the same time we would have liked it if they were made of metal or some other material other than plastic as they’re the main part of the heater in the first place.


Safety with this Optimus-H heater is what you can expect from most others ones and that would be it has an auto shut-off for if the heater overheats or if it tips over.



The heater is quite powerful and you’re able to heat up a bedroom well enough if you have it on its high setting. That said, closing the bedroom door is the most efficient way to use the high heat setting to its full potential. While the low setting is more for personal use and this heater is not meant for heating larger areas such as a living room.


Using this heater is very easy as it uses two dials. With one being the thermostat and the other being the air/heating setting dial.


Build quality of this heater is pretty good when it comes to its safety and structure. We would have liked it if the dials felt more premium as they’re quite loose and have no tactile feel to them.
