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!

What are the Benefits?

  • Slim - Just 2 inches thin
  • Stylish – Beautiful flowing curves compliment any room interior
  • Healthy - Fanless, non-forced air design that doesn't blow dust or allergens into the air and around the room.
  • Sleep friendly - Silent and auto dimming on/off power light in dark rooms, is helpful for light sleepers.
  • American Owned & Built – High Build Quality – ISO 9001 Quality Control Factory Certification
  • Heats Room Size – 130 to 150 square feet
  • Built in Thermostat - Better temperature control
  • Sturdy & Crack Resistant – high tech 21st Century durable materials will not crack or separate at the seams.
  • Industry Leading Warranty – 3 years
  • Easy to clean – smooth wipe clean surface

  1. Very happy with this heater

    Posted by Kim on 17th Feb 2019

    We needed two new heaters, so I bought this one and a competing surface mount passive (fan-free) brand. The Envi heater was much nicer in the end.

    Though both work equally well, the Envi heater looks a thousand times better. The other heater looks very office-industrial and not in a hip way. That brand sticks way out from the wall too, leaving wires in a weird way. And the temp controls are hard to use on that other brand.

    The Envi one was sleek, goes against the wall like it should, and the temperature controls are straightforward and easy to use. We'll use more of these in the future in our new house.

  2. Great Heater

    Posted by Dan on 17th Jan 2019

    This is the 3rd one we have bought. They are great for small spaces such as bathrooms. Very easy to install with the enclosed template.

  3. I love this heater and will buy more

    Posted by Anna on 10th Dec 2018

    I've had my heater for about 2 years now (previous generation). I love it because I could mount it relatively close to the bed and it is safe. I could close the vents in my bedroom because I dislike force air heat (throughout my house). The air is clean and not dry, plus no fluctuation from too chilly to too hot while I sleep. It is very energy efficient, cool to the touch and is perfect for an appx. 130 sf. bedroom. And I live in Michigan where temperatures can go as low as -30 degrees.

  4. Hot Little Heater

    Posted by chforslund@yahoo.com on 6th Dec 2018

    This heater was very easy to install, even for us non-mechanical engineers. It's very attractive on the wall and does a good job supplementing heat from an aging electrical forced-air furnace. A good addition to the installation kit would be a small capsule-type level to make sure it's level on the wall (like picture frame sellers use). The thermostat is great. And the unit is totally silent.

  5. Warm and safe for pennies

    Posted by Judy D from LaFayette, GA on 6th Dec 2018

    This is actually the second heater we have purchased. I have one in my laundry room that before had no heat at all. We have had that one for several years with no problems at all. They are very easy to install and USA made. The one we just bought was for my mother in-law for her bathroom. It's easy to use and safe which were our main concerns for her and she loves it. We highly recommend.

  6. Quiet, efficient heater

    Posted by Lia Middelhoven on 6th Dec 2018

    We love this heater! Very efficient. Totally warms our bedroom. Love that there is no fan running. Just quiet, warm heat. Recommend highly.

  7. Best panel heater on the market

    Posted by Bill L on 6th Dec 2018

    I own three of these heaters; I use them in my mountain house to warm areas on demand.

  8. Great Heater

    Posted by Rich M on 6th Dec 2018

    No mess, no muss, easy to install and provides constant heat which takes the cold out of the air.

  9. Impressive

    Posted by Charlie Mishk on 6th Dec 2018

    Very impressive unit. Sceptical at first but i wanted to try something different. Tried many things in the past to warm up this room that's far from the tstat and in the back of the house. Very easy to set up and use. Installed this and monitored the room for several days to find the rite setting. This unit works so well that im'e going to get another for another room then possible replace a 220 volt unit in my washroom.

  10. Nice space saving and clean line heater

    Posted by Phyllis on 6th Dec 2018

    When we remodeled our bathroom, we didn't want to put the bulky radiator back into the room. This unit has such a slim line to it and was perfect for opening up the floor space where the radiator used to be. Coincidentally, our contractor had drilled a hole through our new floor (ouch) and the electrical cord for this unit fit right through the hole and we have it plugged in down in the cellar because the cord reached an existing outlet. It worked out great for us. The unit puts out a good amount of heat and is virtually silent.

  11. Good looking heater

    Posted by James Miller on 6th Dec 2018

    Very easy to install. Looks good on wall. Can’t wait for winter to really give it a true test. Tried the heater out and it maintained the temperature over night.

  12. Great customer service!

    Posted by Chris on 6th Dec 2018

    Recently ordered 120v heater panels... come to find that we needed the 220v panels. Called eheat and they promptly took care of the situation. Thanks!

  13. Here is why you should get a couple of these

    Posted by Jennifer Ellis on 6th Dec 2018

    I have forced air heat, and one room is just a little uncomfortable. You know that room - even after trying to balance the air flow it is still just a little chilly. If you go in there you need a throw, and so more often than not you just don't bother? Well that was my first eheat. I have it on a timer and by the time I get home from work, I can enjoy tv in the den. It is so quiet and unobtrusive that I forget I have it. Only when someone unplugged the timer and the room was a little off did I realize how used to the eheat I had become.

    My next eheat-er went in the basement bathroom. The only way to use a basement bath tub is if that room is warm and cozy. That one I turn on when getting ready for the tub, and the eheat does the job!

  14. Cozy Factor and saves on propane gas bill

    Posted by Mark D on 6th Dec 2018

    This is the 4th one I have purchased. The heat these give off is amazing, and our home is now very cozy. We have 26 foot high ceiling in our living room and forced air gas just doesn't cut it out here in the Pacific Northwest in the winters. Now we run the Envi's and fire up the gas stove late in the day for a couple hours and we are saving probably $200 per month easily on our propane bills.

    Easy to install. Great product. Fast shipping. Energy efficient. You are missing the boat people if your monthly gas bill is as high as mine gets during the Fall and Winter. AWESOME PRODUCT.

  15. So Far So GREAT!

    Posted by Sandee Strunk on 6th Dec 2018

    I can only review up to a point - but take note, I am a 70-year old female. First, the CHAT customer service gave me spot-on info; then the product arrived in a 5-Star condition. The template is so unique and works so well in installation; the entire installation was effortless; it works so super! What I have to wait on evaluating is how much money I will save. I will compare to fall last year - but it should be evident just in my electric bill next month. Also, how long will it last? TBD. We bought the plugin first for the master bedroom and if it performs consistently well, then we intend on buying the hard-wired version for every room and then use the original plug-in in our RV. Thanks so much! Granma
