The Technology

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

Dozens of heating methods were evaluated to fine tune the envi heater, but eventually the solution was found outside the traditional heating industry. A naturally occurring phenomena called the "stack effect" provided the basis for the final envi heater design.  Fanless heating could be enhanced by simulating multiple pathways, or “stacks,” inside the envi.  This technology boosts the flow of cool air from the floor of a room, into the unit, maximizing heat transfer out the top.  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 the house or office.


The envi is:

  • Economical - low wattage technology (only 475watts)
  • Efficient - 100% Pure Convection Heating
  • Innovative - New Patented Stack Convection Technology
  • Safe for children, seniors, and pets - Cool-to-the-touch (90°F), Wall-Sens(TM) technology and automatic thermal cutoff
  • Simple to install  - Installs in minutes, no drilling required
  • Slim - Just 2 inches deep
  • Stylish – Beautiful flowing curves compliment any room interior
  • Health-promoting - Fanless so it doesn't blow dust or allergens into the air
  • Sleep friendly - Silent and auto dimming on/off power light
  • 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
  • Cord Storage - Cordset can be stored inside the heater for a more attractive look.
  • Hardwired Approved - Hardwired models are certified and approved for permanent electrical installation without need of a cord-buddy under UL Safety Listing 2021. The envi heater finally answers the need for a legal and safe, hardwired electric panel heater. (Only on models HW1012T[N] and HW1022T[N])

  1. Excellent Quality and Great Overall Room Heater

    Posted by jon on 28th Aug 2015

    I tried a couple of other types of electric wall heaters and was not satisfied with the performance. I saw these on the internet and although more expensive I tried one and am glad I did. It mounted easily and works like a charm. Like all heaters of this type it takes a little while to warm up the room so should be left on but it easily keeps a 16x16 room comfortable. Great for a bedroom. Highly recommend this!

  2. excellent product

    Posted by virginia on 27th Aug 2015

    This is our third heater of this type...using them to help heat a large basement apartment we have for rent in our home. They do the job quite nicely...put out great heat, are quiet, efficient, and best of all, has had little effect on our electric bill. Would recommend this, and have, to others.

  3. Simple, real, workable, practical and safe.

    Posted by Lobsterboy68 on 21st Aug 2015

    The product was what they said it was and works like it is supposed to. Buy it, you will not regret it. Leave it on all day during cold days and a nice warm heat will greet you when you come home.

  4. Great product

    Posted by Guy Biagotti on 11th Aug 2015

    I purchased 3 Envi plug in heaters and installed them today. It took 25 minutes for each of the first two installations and they worked well. The third I installed had a on/off switch defect which did not allow it to turn off so I called your company and they are sending me a new one with a return container for the defective one.

    It give sufficient heat. It is well engineered and easy to install. I showed it to several of my condo neighbors who will be purchasing these also.

  5. eheat

    Posted by Richard Whitmire on 6th Aug 2015

    I have had a similar product for about 10 years. This product is just like the other product only greatly improved. It has many improvements such as an on/off switch and a thermostat. The price is about the same as I paid 10 years ago. I would highly recommend the "envi heater".

  6. Free Heat by Solar Panels

    Posted by Unknown on 1st Jul 2015

    This heater is so energy efficient that we heat our whole home almost for free using Envi heaters and 1 gas wall heater. We live in a moderate climate in California, but the temps in the winter get pretty chilly. Our electric bill for the whole year last year was about $250, and we had 5 Envi heaters hooked up to thermostats.

  7. Money well spent

    Posted by Unknown on 24th Jun 2015

    The product came with perfect packaging and straightforward instructions. It was very easy to install. The first time it is turned on, it takes a while to warm up the room but after that it keeps the room in a constant temperature.

  8. Love this product

    Posted by Jean on 18th Jun 2015

    Purchased in early winter of 2014 and used through out the season to keep our lower level guest bed room livable. It was great to keep it on a low setting when we did not have company and then turn up the heat before guests arrived. I did not notice any significant increase in my electric bills. The product is safe, attractive and does a great job. My only criticism is that I wish the directions had advised me to tuck the extra length of cord into the back before we placed it on the wall screws. It was a little tricky for us to get it placed and once up we did not want to take it off, tuck in the extra cord and hang it back up. Thus the extra cord shows but it is no big deal to us. I have given your information to numerous people, I like the product so much.

  9. A welcomed surprise!

    Posted by Lisa H on 16th Jun 2015

    I learned about this heater from an advertisement in The Family Handyman magazine after having built an addition to my house for my Mom. She wasn't getting enough heat into her area so I had given her my space heater. It worked, but took up space and didn't look very pretty. The Envi heater looked like it would be a much better option as it was thin and would be out of the way mounted on the wall. I was very pleased with the price, the look and the ease of installation.

  10. Best low wattage heater you will find.

    Posted by Freddie Tomlinson on 15th Jun 2015

    I have 2 of these in my living room/kitchen and during the winter the furnace doesn't even come on. And if the power goes out I have a generator and it easily runs both heaters and the rest of the house!

  11. outstanding product

    Posted by Dan on 4th Jun 2015

    Everything about this product deserves 5 stars: packaging, instructions, engineering, design, quality, ease of installation, performance, and ease of purchase. 5 stars, hands down.


    Posted by Unknown on 3rd Jun 2015

    I love these heaters. I originally ordered two and have since ordered an additional two more heaters for my mountain home which sits at 6300 feet in the mountains of Southern California.

    They are perfect for zone control and are ABSOLUTELY SILENT when running, easy to install and attractive in appearance.

  13. I'll keep buyng them for as long the price drops!!!

    Posted by Giuseppe Bianco on 3rd Jun 2015

    I bought eight of this units in different times, three instances. I liked them since the first time for the performance, look and simplicity in the installation! I considered the price a bit high, but some discounts made me more comfortable in the purchase. If I will see future savings I will definitely get more! I would encourage anyone with a heating problem to consider E-Heat!

  14. great room heater

    Posted by Unknown on 2nd Jun 2015

    I bought one to heat a back room in our house that wasn't getting heat. The Envi plug in unit was easy to install and does the trick. I like it way better than wall heaters that blow the heat around. This is a much more comfortable and consistent heat. I ended up buying 3 more units I liked the first one so much.

  15. Purchased based on previous purchase

    Posted by Ed Wigfield on 2nd Jun 2015

    As it has been unseasonably warm in this part of PA I have not yet installed the 2 new units. They appear to be a serious upgrade to my original purchase about 5 years ago. The original is still working fine and I am sure these will also.

  16. easy installation

    Posted by Mimi C. Waynesville, NC on 28th May 2015

    We purchased this heater based on an ad in the Family Handyman and the online reviews for our NC mountain house. We received it just days after ordering and installed it on a 76 degree day, so we did not have a chance yet to see how well it heats the small family room on the lower level of our north facing house. It started up right away and we think it will be a great supplement to our heatpump and propane fired whole house unit this winter. Last winter it went to minus 9 (F) so we really hope it will help with our heating bills. Will update this post after we have had a chance to really check it out!

  17. great product

    Posted by Unknown on 25th May 2015

    We liked the product very much. It was very to easy to install and operate. I just ordered the second unit.

  18. Adding equipment to additional buildings

    Posted by Mike Patti on 20th May 2015

    I have previously added the envi heaters to 3 fire stations in hopes of adding comfort and reducing the operating costs. I have been pleasantly surprised with both!

    all have been performing well, keeping the dorms and living quarters at a comfortable temperature through the winter and during cold days.

  19. Better than expected!

    Posted by Roger O on 13th May 2015

    The Envi high-efficiency whole room plug-in heater works better than expected. After installing it in the great room of an open plan house, we found that it quietly and efficiently took the chill out of winter. After installing the unit we rarely had fire up the oversized furnace in the attic where we live in northern California, resulting in a better less drying atmosphere, big savings in electricity, and a more comfortable environment. If I can free up enough wall space in other rooms I will buy a few more for next winter and hopefully forget about using the hated forced air megalith that came with the house.

  20. Took the chill off

    Posted by Kevin on 13th May 2015

    I bought 3 units and used 2 in a rental and kept 1 for my living room. It's amazing how it takes the chill off the room. I don't have to heat the entire house to be cozy on the sofa now. I prefer to sleep on the cold side so this was the perfect solution!
