Envi Plug-in Electric Panel Wall Heaters for Indoor Use, Energy Efficient 24/7 Heating w/Safety Sensor Protection, Patented Quiet Fan-less Design, Easy 2-Min Install, Space Heater, Made in USA

I have to defend these heaters for their quality and efficiency. I own 9 of these and they are my only heat source in an old 1860's 3 story house. I will say before we upgraded some of our insulation, they worked overtime to keep the temperature at 67 during winter here in upstate ny. When the air is wet and cold in the single digits we can barely keep it at 66 to 67. That being said, our home still has wall insulation rated R13 instead of R21 which is the lowest recommended insulation for our area. The outside walls have not been wrapped properly either. Once we upgraded 2 large areas, these little guys pulled their weight and we achieved 70 degrees easily with single digits temps. Extremely easy to install. Safe and durable. I have owned mine for 4 years. Lightweight. Quiet design. I have heard about clicking noise being bothersome, but I am a light sleeper and don't have trouble with mine. The power bill is not too bad but is hard to gage because our power company charges keep increasing. UPDATE! 2025 2026 winter. I have recently paid 20,000 dollars to rewire my entire home. There were many heaters which were not working as effectively because they were not on a designated line. Since the rewire, they are far more efficient. Recent temperatures were 60 mile gusts, 16 degrees with feel like temps of 6 degrees. My home is 71 degrees. Just FYI. Check your wires, or outlet loads.

We needed a heater for a small room with our washer & dryer that the main heating system did not reach well. We are in Northern New England so it gets very cold. This heater was very easy to install, very well designed for safety and efficiency. This works perfect! I keep it on one of the lowest setting and it keeps the room nice and warm. We shut it off in the warmer seasons with a push of the power button. The outer cover does stay cool to the touch so no worry someone will get burned or burning something than leans up on it. Much better design than the 'panel" units that require difficult mounting spacers and get very hot to the touch. Only almost con is the temperature control on the lower settings are touchy, hard to get a good warm level and not too high. A light indicator of when it is heating would be nice. It does have a light indicator when it is turned on. Recommended.

I was so excited to try these heaters. We have an older home and have used 1500 watt electric space heaters for years, no problem heating rooms. I kept seeing the Envi heater ads on social media, making these look incredible, very safe, efficient and could even help to lower our electric bill. I went all in and purchased three, two of the 500 watt for two approximately 10 x 10 upstairs bedrooms, and one 1000 watt for an approximately 12x 12 downstairs bedroom. Installation was pretty easy, I installed them when our outside temperature was in the forties. One upstairs bedroom seemed to heat the room well, the other, not so much. I kept turning the thermostat on the heater up and up and still couldn’t get the room above 67 degrees. The downstairs bedroom was even worse. I reached out to Envi customer service, thinking the 1000 watt should easily be able to heat our bedroom on a forty some degree day. I figured we had a defective heater and would exchange it. Customer service was a joke, no troubleshooting or anything, just told me that the heater would not work for our space and that we must not have enough insulation. Huh? That was based off of no questions asked by support, so it seems they don’t have much faith in their products working. No help with a return or anything, luckily I purchased through Amazon. This morning is our first truly cold day, outside temperature in the twenties. The heater that seemed to be working well upstairs is struggling, thermostat set the highest, but room temperature is 63 this morning. Second bedroom temperature is 53, that heater is also set to the highest. I just went out to our garage to get our old space heaters. Returning all three Envi heaters. What a joke.

We are on a second one of these having bought the first one 13 years ago. We only use it in a small area with a plug-in thermostat purchased several decades ago. We would had expected the first one to last longer however they are not cost prohibitive. The unit heats well and is the safest we could find for our application. We researched other products when the first one died and did not feel there was are better replacement. Years ago we used heaters that were ceramic style wall heaters that did not have covers in bedrooms. They were not as efficient and without a cover would expose one to a hot surface. We believe, when paired with a separated thermostat, these are a good option for smaller spaces. Compared with most other independent space heaters they are much less likely to cause bodily harm. They are very quiet and attractive. When first initiated they are quite smelly and need to cure over several hours. We would advise opening windows.

This is an amazing product. Installation was remarkably easy. I just went to buy another tonight and realized I have had my current one for four years. It produces consistent comfortable heat. The highest setting is really powerful and its ascetic is nice. I think it is worth a-lot more then $200.

We purchased the 1000-watt model for a bedroom of about 120 square feet to avoid using noisy central air at night. Unfortunately, the heater did not meet our expectations, and given its high price, it was not worth the purchase. Here’s a closer look at our experience: DESIGN AND QUALITY The heater has a stylish and sturdy design with a high-quality feel. Inside, there is a compartment to neatly hide an extra power cord—a thoughtful touch. INSTALLATION Installation was very simple. All it took was a screwdriver and about 10 minutes to mount it securely on drywall. FUNCTIONS We opted for the model with a rotary thermostat, as we didn’t see the need to pay extra for a display and timer. Instead, we paired it with a Tapo smart plug featuring energy monitoring, which works excellently as a timer and tracks energy consumption. However, the engineers made a baffling decision regarding the power indicator. While it shows whether the power is on, it doesn’t indicate if the heater is actively heating or in standby mode—there is no heating/standby indicator. On the other hand, they did include a twilight sensor that dims the power indicator in the dark, which seems unnecessary. EFFICIENCY Our goal was to maintain a temperature of 68–69°F in the basement bedroom at night so we could avoid using the central air system. At its maximum thermostat setting, the heater performs as expected, but only when outdoor temperatures aren’t too cold. When temperatures drop below 30°F, it struggles to keep up and fails to deliver adequate heating. COMFORT OF USE The advertising promises “dead silence,” but that’s an overstatement. While it is quiet compared to fan heaters, the thermostat makes a loud clicking sound when it turns on and off, which is far from silent. Additionally, there are blue flashes visible inside during this process. After a few months of use, the heating element developed a faint but noticeable hum, similar to the sound of high-voltage power lines.

I bought a different heater for a cold room. It arrived broken and looked cheap. I found this one by searching google reviews. It is really easy to install, looks very nice, and heats nicely. It's a great addition to our home.

So we just got our forever home which is 3800 Sq. Ft. Compared to our older 2000 sqft home our bill is the same and this is one of the reasons why. Now to start out we now have a basement (finished) and newer hvac but we DO NOT USE THE HVAC HEAT AT NIGHT. the efficiency end of this come from a lack of a fan and a simple heating element using convection. No motor = less power draw. Now these (400 watt) units do not hear a room very quickly. But being on a thermostat means yoy can just leave it on and it will shut down when the room is warm. The problem with power draw on a full home HVAC is that once Temps drop below a set temp (usually 45 ish degrees farenheit) there is an element that run constantly whether it's blowing air or not. This is to allow system to begin blowing warm air when the blower system kicks on and reduce startup time. This happens always when the system is in heat mode regardless of the set temp of your air handler. (This is why reducing thermostat temp doesn't change your bill a whole lot) so we have 4 of these units. One in each bedroom. We run the central heat to 72 until bed and then turn system OFF. These heaters maintain fine but will struggle to bring a large room to temp if left off but ALL 4 RUNNING USE 1600 WATT TOTAL. that us only 100 watts more than a small desk heater from Walmart. In the morning we run the central heat to catch the rest of the house up, but staying warm without running 3.5 tons of hvac and roughly 5000 watts has kept a power bill of roughly 240 for this large house with all electric appliances. Down to 80 in the fall when demand is significantly less. We are in north Alabama so it's not crazy cold all the time but know how these systems work will help you optimize its efficiency. Lower wattage units tend to last longer, higher watt heat faster. And there will be a smell when you first start it up, INSTRUCTIONS SAY TO LEAVE HEATER ON HIGHEST SETTING FOR 72 HOURS. presumably this is evaporating whatever coating is used in the manufacturing process but it does go away once it's run. This is only my 3rd review ever. 5 stars. Stay warm
