The Technology

The dual-stack convection technology featured in the Envi was born out of years of research and development to find a solution to effectively and safely heat a room using the smallest possible, amount of electrical heating energy.

Dozens of heating methods were evaluated to fine tune the Envi heater, but eventually the answer was found in a naturally occurring phenomena called the "stack effect". This provided the basis for and eventually we won a patent for the final Envi heater design.  Natural convection, fanless heating is enhanced by simulating multiple pathways, or “stacks,” inside the Envi heater.  This technology boosts the flow of cool air from the floor of a room, into the unit, and maximizes heat transfer out the top of the heater.  The resulting process creates a slow moving transfer of warm air around the room, effectively warming the occupants.

The result is a 100% pure convection, fanless heater that uses minimal energy but also effectively warms each room in a house or office - or any room or space for that matter!

  1. Great product

    Posted by David B on 20th Sep 2019

    Bought this for a small bathroom at my rental
    Cabin. It does the job very well is nice looking and is energy
    Efficient .

  2. Best investment ever!

    Posted by Dena Tolchinsky on 10th Sep 2019

    Here at the Oregon coast, we get alot of wet,rainy weather, creating damp conditions in the house. These sleek, low-profile heaters are perfect. I have one in each room, and I leave them on the lowest setting. Built-in thermostat shuts the heater off when not needed. I'm 60 years old and partially disabled, but I installed them myself....took about 5 minutes each. And they reduced my electric bill by about half! And the surface doesn't get hot, so no burn hazard! I highly recommend these heaters.

  3. Ideal for my situation, saved me a lot of money!

    Posted by John Powell on 28th Aug 2019

    Very satisfied so far, the product and perfect for my situation.
    My appartment had old gas pipes for a gas furnace, the pipes corroded and would have cost $4K to replace. I bought 3 envi heats for a 10th of the price, and they do the job.

  4. Just what I need for my bird room

    Posted by Jess on 28th Aug 2019

    I bought the Envi plug-in wall heater for my bird room, because there are no harmful fumes, it is silent, low wattage and does not take up space on the floor of the room. After an initial burn-in period, I have only run it on low for my bird a few times during the summer, but I think I have made an excellent choice for my purpose. I placed it about 3 feet from the bird cage, and the heat goes directly up to him. With more extended use, I have no doubt that it will heat the whole small room in the winter. Installation went just fine (I’m an older lady and watched a couple of YouTubes), and the gentleman who answered the phone at EHeat was more than generous to answer my frivolous questions during three separate calls. I am very pleased with my Envi wall heater from EHeat.

  5. Love these heaters

    Posted by HGL Midland, Michigan on 24th Jun 2019

    Bought two of the plug in Envi heaters to take the chill out of a small 600 sq. foot basement remodel, and they worked better than I expected. Set both heaters to near there lowest setting and they brought my 55* basement up to 69* in as little as 48 hours. PERFECT! Very cool to the touch, and looks great.

  6. Best Wall Heater Available but Hard to Find

    Posted by Jeffrey J. Waters on 12th Jun 2019

    I would have never even known about this great American made, safe, quality product if someone had not given me some Handyman Magazines. I am so happy with it. EHeat, as much as you may not want to you simply must make your product available on Amazon, or you are loosing sales and planning your own obsolescence. I hate to say that, but it is true and you know it.

    This is the best wall heater available and made in America. It should be easier to find.

  7. It actually works! Much cheaper than other options I was looking at

    Posted by Cynthia S on 8th May 2019

    I had serious uneven heating issues in my two-level condo (bottom floor was freezing, upper floor was too hot). I had two different HVAC specialists come and tell me there was nothing they could do with the ductwork. I found that hard to believe, but two different specialists told me that. One of them recommended doing a "mini-split," where they attach those big, bulky things to the wall (like in a motel). To add one to each of the two bedrooms, they quoted me $8,000 (or $10,000 if I wanted to install the new kind that recess into your ceiling). It sounded way too complicated and expensive, so I googled and found the Envi heater. It seemed like such a simple, cheap solution. I wasn't sure if it would work, but I bought two (one for each bedroom). I installed them myself, and I'm not that handy (just drilled two holes in the wall). And they really actually work. Each bedroom is around 12 ft by 11 ft. I don't even have it cranked up all the way, and it heats the whole room (and even the hallway, if I leave my door open). I live in DC, so the winters get pretty cold. I did notice the wall above the heater felt very warm, which made me nervous. I chatted with the EHeat customer service, and they confirmed the hottest temperature it gets is maybe 150-ish (I can't remember exactly), and they said paper/paint/wood/etc. doesn't burn until 450 degrees. Overall, I would definitely recommend.

  8. Great way to heat the cold basement consistently!

    Posted by Anthony on 3rd May 2019

    I spent quite a while looking for solutions to heat a basement that would stay about 60 degrees year round without leaving a standing heater on all the time, in addition to the cost and safety issues. I came across eHeat and their solution is genius! I easily installed the heater to the wall and leave it running 24/7 at the high setting and my basement will stay much warmer between 66 and 68 degrees which makes it way more comfortable to work and relax in! I definitely recommend it and will consider getting another one to heat up another area of the house. Excellent product!

  9. Great heater for RV

    Posted by Unknown on 2nd May 2019

    Great heater. This is the second one I have purchased. I put them in my RV. Easy to install. Keeps my RV comfortable even in low temperatures

  10. Nice Product

    Posted by Stephen B on 2nd May 2019

    I just received my Envi Wall mounted heater a couple of days ago. I live in Danielson CT (NE corner by MA and RI)last night the temp dropped to 28 degrees. My office is in the basement of my home 10'6" x 12'6' with a 7' ceiling. I just setup the heater yesterday which was very easy. I am trying to adjust the heat to about 68 degrees. I set the thermostat to a low setting, since it is not digital it is a guessing game for the right setting the temperature was 63.1 degrees at 7:30am so I turned the dial to increase the temp it is currently 67.3 at 9:30 am. Things I like so far 1. absolutely quite no noise 2. easy installation 3. since mounts to wall takes up no space 4. looks nice and is cool to touch 5. does not appear to be drying out the air humidity has stayed constant at 42% so far 5. price is far
    Things that could be improved 1. make the thermostat digital so that it is easier to dial in the desired temperature

  11. Perfect for a bedroom

    Posted by John A Jarvis on 25th Apr 2019

    This is the second envi heater I have purchased. Liked the first one so much I bought a second one. Very easy to install and not unattractive at all. Not hot to the touch, which was very important to me as I did't want my grandchildren to get burned as they would with a regular space heater. I highly recommend this product!

  12. Compact but very effective

    Posted by Neil G on 20th Apr 2019

    I removed a steam radiator and replaced it with this unit to maintain an even temperature in the room. I am very pleased with the performance.

  13. Exceeded Expectations

    Posted by Suzanne W on 1st Apr 2019

    I had never seen one of these in use, but I took a chance and ordered one. It puts out more heat than I anticipated, and it’s totally silent. Its design is understated and unobtrusive, which is a good thing. Love this heater!

  14. Total compliment to my wood heat!

    Posted by Lorna on 23rd Mar 2019

    I heat totally with wood and thought this would help when I am away. It does! Was very easy to install and am loving the efficiency!

  15. Love it so far!

    Posted by Linda on 21st Mar 2019

    Purchased this for a cold bathroom as an alternative to turning up the oil heat. Easy to install (or so I'm told by the installer) and silent. It provides a nice, even heat that holds constant whether we leave the bathroom door open or closed. Very happy with this heater.

  16. Easy to install and work like a charm

    Posted by Amy on 21st Mar 2019

    Installed 4 heaters perfectly in under an hour. less than 10 min. each. Totally easy, they work great. No weird smell after 15 minutes of running time (and only the first time). I highly recommend!

  17. Great purchase

    Posted by Dr Sheryl Bair on 17th Mar 2019

    Very satisfied with the product. Easy to install, quiet and has many safety features.

  18. All you said and more

    Posted by Unknown on 17th Mar 2019

    Great heater so far,very easy to install and looks great. Even got here earlier than expected. Although a digital thermostat would be a great.

  19. Inexpensive low-cost heating

    Posted by Jeff on 17th Mar 2019

    The envi heaters have worked out great for our home and for our children's home. They are cost-effective and extremely quiet.

  20. Works great

    Posted by John Moher on 16th Mar 2019

    This is the second one I purchased. First one for an extra heater in daughters bedroom, and the second one I use in the basement family room.
