This works well for our bedrooms which are at or slightly above the 160 sqft limit. We live in a northern state, but our average temperatures are in the 20-30s in the winter and these have essentially replaced our oil heat in the bedroom zone. I keep the heater at the lowest setting and use a new echo dot with temperature setting to control a smart plug. This setup is working well for me, but I was disappointed that I needed to go the extra step because the temperature adjustment on the heater doesn't seem to shut off the heater based on the room temp (I believe it is a timed on/off cycle) and works well enough that it will generally just keep heating the room well above the temperature we want it to maintain. Other than the controls which have a number of options to fix it works great. The heater is only 400 watts so I barely notice a difference in my energy consumption.

Bought this for or 22' 5th wheel.
Really works nice to get the temperature up when we have shore power.

To start off with, I am using this heater for a specialized purpose. I finished my basement a couple years ago and I made a special effort to insulate the water pipes to ensure they would not freeze in the winter. However, it turns out there is a section of pipe that runs up from the basement level to an outside wall above a basement window that is completely inaccessible. The extra insulation I added to the exposed pipes and then sheet rocking them in actually cut off warm air from keeping the pipes from freezing. Since then We've had to hair dryer the pipes from freezing a couple times each year with this year being the worst so far. Thankfully, I switched them to PEX pipe which has been a life saver in it's own right.
After reading the reviews this little unit seemed to be perfectly tailored for my purposes. The wall where the pipes freeze is also next to a frigid window well located next to my desk. The basement stays cool year round- but next to that window it gets really cold. I mounted the Envi heater on that wall a few feet below where the pipes are located and monitored the wall with a laser temp heat probe for over a week. Previously, the cold spots on the wall could dip to the mid 60's indicating that the interior was much lower temped. With the heater in place, it heats the wall which in turn becomes an extension of the heat unit it's self radiating heat into the room. The wall temp right above the output is 130F and 110F 4" above that. At the very top of the wall and area of the ceiling above it I get a steady 88F. Keeping in mind that a laser temp gun measures only the reflected heat, this indicates the sheet rock is as warm as 135F but on average about 90F. I'm not concerned about any damage to the sheet rock based on what I've seen over the past 10 or so days. I have a plastic tree my wife dumped on me fairly close to the unit and the warmer "leaf" is only 80F.
The unit looks terrific for what it is. The power usage is very low and the slow heat output over time keeps the 370ish SQFT basement room it is located in just the right temp over the ambient temp of the room.
It would be interesting to see what this unit does in a small room. It seems very safe, does not present an unusual fire hazard. It's mush safer than a space heater- but is not the type of heater you would use for directed, quick heat.
The price seems high, except for the fact that it's advertised as made in the USA. For that, it seems like a fairly priced unit that I hope lasts years.
One of the rooms in my basement is a recording studio, another benefit of this design is that it will not contribute to any room noise like a space heater would. This is a great practice space option.

Update: We are really very happy with this purchase. Would reccomend.

The media could not be loaded. The Envi wall heater has been a great addition to our home. We put our first Envi heater in a room that stays colder than the rest of our home in the winter, and it has helped to keep the room comfortable. Compared with a space heater, the Envi wall heater does not take away any space in the room since it mounts on the wall and is thin. Also, it runs silently--all the heat with none of the sound! Having no moving parts means there is no filter to clean, and from what I can tell, the way it is designed seems to be as energy efficient as possible for an electric heater. And the design is attractive--not something I feel like needs to be hidden in a nice home.

Attached is a photo of our newly installed heater from Amazon along with a video showing me unboxing and installing the heater. Since this was my second Envi heater to install, I felt confident with making a video from start to finish. When I installed the first heater, I thought there was a bit of marketing hype to claim that it "installs in minutes." When I went to install my first heater, I gathered the normal tools"¦a level, tape measure, drill, screwdriver, etc. But then I was pleasantly surprised to find that the box insert doubles as an installation template that rests against the wall and floor. That means NO level and NO tape measure is required. Also, the drywall in that room was only a few years old, and the included drywall anchors went right into the wall like butter with a cordless screwdriver"¦NO pre-drilling needed. It was really fast and easy to get the two mounting clips into the wall in the perfect position. From there, the heater just hangs on the two mounting clips for a level, flush-to-the wall installation.

I'm also a bit of a perfectionist. Having a long power cord dangling from the wall or tied up next to the heater is unsightly. But they thought of everything"¦any extra power cord length can be pushed back into the cavity where the cord comes out of the heater, which just leaves the exact length needed to reach the power outlet. And the power cord has a right-angle plug, so the cord rests neatly against the wall instead of sticking out from the wall. There are also electrical punch-out holes on the back of the heater for people who want a direct wired heater with no exposed outlet.

The only thing I learned while installing this new heater (which you can see in the attached video) is that this heater was installed in an older home, and the drywall is extremely hard compared with my first installation. If I were to install the heater again, I would just pre-drill the two holes before screwing in the wall anchors. Other than that, installation went smoothly with no surprises.

The Envi heater draws up air from the floor and outputs a steady stream of silent heat out the top of the heater. The thermostat lets the heater run when needed and automatically turn off when your room is at or above your desired setpoint. The top vent is angled slightly outward, so the wall above and behind the heater stays at a temperature that is still comfortable to touch. And the front of the heater stays even cooler during operation, so I don't worry about a child or pet getting unpleasantly surprised if they touched the heater while it is in operation. It is easy to set and forget!

Here's to a more comfortable room!

I bought this plug in panel heater for a small room that is about 11 x 13 feet that has several windows. This heater is pretty much passive in that it doesn't use a fan but just uses a more normal process of heating cold to warm air rising from the bottom to top through it's designed stack of fins (if I'm saying that correctly).

The heater is well packaged and there the instructions were helpful. Part of the box is used as a template as to were to mark for hanging. The heat output is better than I thought. I read others reviews and used stronger wall anchors and also added a plug-in thermometer as seems the built-in thermostat isn't that accurate.

Overall, I'm quite pleased. Here are my likes and dislikes:

Likes
------
- slim set up close to the wall
- good heat output for its size
- passive heating (no fans)

Dislikes
---------
- thermostat not too accurate
- difficult to see heat level setting
- a bit pricey

I give the Envi Plug-in Electric Panel Wall Heater 4 stars.
