(Last Updated On: February 27, 2018)

The three main categories of heater appliances are personal heaters, space heaters and then there are whole room heaters. Depending on what your needs are you’re going to go with a specific one and you might wonder: Why not just go with the Whole Room heater and call it a day? Well, that’s because those types of heaters are simply too powerful and also the price difference between Whole Room heaters and smaller types is actually quite different.

In this review, we’re going to be focusing on this Tenergy Ceramic Space heater that has the best of both worlds; which includes it being used as a Personal heater and also a Space heater too. Tenergy is a brand that has reached into many consumer categories and has proven themselves to be quite competent in making quality products within different fields. It’s surprising, so let’s see if they’re able to excel with heater appliances.


Feeling the Heat:

It’s very small sized heater and as a result, with it being small it means that it’s also going to be using a small fan too. At the same time, the heat that’s outputted with this heater is actually pretty warm. This is the case with other small heaters, so even if you have high and powerful heat coming out, the size of the fan and the force behind it matter equally as much.

That’s not to take away from the heating capabilities of this heater though, just trying to put it into perspective. The Low heat has an output of 900Watts (3,070 BTUs). While the high heat has a 1,500Watt output (5,118 BTUs). The low heat setting with this heater is going to be most useful for using it has a Personal heater simply because the heat coming out is not nearly as warm as being able to heat up an entire room. Using it as a personal heater is best if you keep it about 2 feet away from you to actually feel the heat.

Using it as a Space Heater

Using this Tenergy Space heater on its high setting is the way that you want to be using it if you want to heat up the space around you. However, this heater can actually heat up small bedrooms as well, and we have a tip for doing so. The tip is closing the door to your bedroom so that outside cold air won’t enter and the warm air that the heater lets out won’t dissipate outside the bedroom.

Heating up an entire room is going to take a while and we highly recommend looking elsewhere if you’re actually looking for a heater to heat up an entire room. As this one is not really as efficient at doing that, as other heaters that are actually built to heat up an entire room.

There’s is also a third setting with this heater and that would be the fan setting. The fan setting isn’t exactly a fan. By that we mean it does output just plain air but the air isn’t cool like it would be with a dedicated fan. It’s more of an air circulation setting that you can use to make the warm air that comes out of the heater to keep moving around the room, so you use less of the heating part of the heater.

Power Usage:

Power usage is going to differ from user to user, and that’s based on what heat setting you’re going to be using most often. If you’re going to use the High heat 1500Watt then make sure that you’re using it as proficiently as possible with the recommendations of closing the room off so that you make the most of the high power heat. Doing that will limit your time of having to use the high heat setting.

While the Low heat setting is perfect for very long duration use and won’t raise your electrical bill nearly as much as it would by using the heater on high heat for a very long time.


Functional Components:

Using this heater is actually very simple. It uses a 6-foot power cord with 2 prongs and once you connect that into an AC Outlet, you’re ready to use the heater.

To the side, is where you’ll find two of the dials that this Tenergy heater uses. One dial is for controlling the Power of the heater, turning the fan on, and also switching between Low and High heat. The other dial is for controlling the thermostat and all it has is a positive and negative setting that you can use to set the temperature. We would have liked this heater to have specific temperature ranges, but with the way that it’s designed, it’s basically the norm with most space and personal heaters.

That’s basically it, all it takes is the use of just two dials to use this heater. At the front is where there’s a Red light that comes on to indicate that this heater is actually on and running. One of the cool features with this heater is that it has a 15-degree tilt capability when it comes to vertically turning it. Having the heater face up is good for heating as heat rises and therefore it can spread faster that way.

Size and Weight:

It’s very small heater, with a height of 9.8 inches, a width of 10.6 inches and a depth of 5.3 inches. The weight of this heater is 3.9 pounds. So it’s very easy to move around if you want to and we even found that it was actually quite easy to take from one location to another and use it there too. That’s one of the best benefits of owning a Space heater, as it’s just so small and that makes it portable.


Structure and Material:

The outer part of this heater is made of plastic and the front grill part is made of metal. Overall, it’s a very well built heater, and we worried that the tilting ability of this heater would make it build quality less stable. However, that’s not the case at all, and having the heater mechanism in the center is just fine and holds no problems that we’ve experienced.


Safety with this heater is pretty good as it has an overheating automatic shut-off. That said, it does not have an automatic shut-off when it comes to tipping over.



The low heat setting with this heater is most useful for personal use because of the size of the heater as a whole. For actually using this heater as a Space heater, then using the high setting is going to give you the best results. Heating a whole room might be possible if you close the door to make sure that you’re taking advantage of as much warm air as possible.


It’s a very small heater, and that makes it very easy to move around with it if you want to travel. Also, it’s easy to use with just two dials controlling the heat setting and also the thermostat. The power cord should be longer though, as a 4-foot power cord simply isn’t very long at all.


The build quality is very good structurally as the plastic is fire resistant and it makes use of automatic shut-off if it overheats. It does not automatically shut-off if it tips over though.
