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. We love envi heaters!

    Posted by Jeke on 3rd Dec 2018

    These are great little heaters. We use them in many rooms. Easy to install, but be sure to read the instructions, as it can take a little work getting them set properly so that they turn on.

  2. I love my Envi heaters!

    Posted by Lea Sammons on 30th Nov 2018

    I now own three Envi heaters and have them throughout the house. They are completely quiet and have a very even heat. I would definitely recommend!


    Posted by Ralph on 27th Nov 2018

    HEATS up my bathroom very well! No more cold duff in the morning. Fits nicely against wall and off the floor ...for easy cleaning. Quiet, no sound and radiates the heat well from floor to ceiling.

  4. Great Heater - living room 73deg but outside is 16deg!!!

    Posted by Mark McMahon St Paul Mn on 26th Nov 2018

    installed in 10 minutes keeps my living room in my condo at 73 being 16 outside and my living room is 12x14 set at the 4 o'clock position

  5. Great heater

    Posted by Michael Riffe on 19th Nov 2018

    Just received my heater today and in just a couple minutes I had it on the wall thanks to the included template. After having it on for a few hours the temperature on the front was around 90 and at the top was around 120. I will be buying a few more for my house.

  6. Excellent US product

    Posted by E.P. Colorado on 15th Nov 2018

    I have purchased 4 of the heaters over the past 2 years and have found them to be great supplemental heating for our home. The last 2 units we purchased went in our bunk house and work well to heat it as needed during the winter.

  7. review on Envi heater

    Posted by Steve on 12th Nov 2018

    This is a great little heater. I have purchased and installed 2 of them. Takes about 20 minutes.

    Puts alot of heat out. Silent, cool to the touch, attractive and efficient.

    My only suggestion would be to offer it with a longer cord. Cord is about 6 foot and if the outlet is on the left of the heater a longer cord would be helpful for some installations.

  8. Exceptional product

    Posted by Susan B on 12th Nov 2018

    This is my third purchase of this fantastic, economical unit. It exceeds all my expectations. Great price, fast shipping and a truly wonderful heater.

  9. Love this heater!

    Posted by CP on 11th Nov 2018

    We have one of these already installed in a basement bedroom and we absolutely LOVE IT. It warms effectively without raising our heating bill much at all. It was very easy to install and operate. Very pleased with this product.

  10. Outstanding Product!

    Posted by Chris N on 11th Nov 2018

    I just purchased and installed my third Envi heater. We just moved into a new home and sadly chose to leave two heaters behind in our old home.

    I bought this heater to take the chill off of our master bedroom which is above the garage. This is the perfect product. I keep it on a low setting, but if I want to really warm up the room I just crank it up and let it go!!

    Installation is a piece of cake thanks to the genius template included in the packaging. Be careful not to damage it when unpacking your heater.

    I could not be happier with this heater and the service from this company.

  11. Wow! I made the right purchase...

    Posted by Elizabeth W on 11th Nov 2018

    After my propane furnace broke a few weeks before winter I was in a panic. Without the thousands of dollars to replace the furnace, I turned to my faithful little Envi heater. I bought this one last winter to supplement the very expensive propane with some electric heat and it gives off some nice heat. So with the furnace dead and not much money I decided to buy 2 more Envi heaters and see what they could do for my little 650 square foot house. I got them in the mail last week and since then it has been in the 20s outside and in the 60s in my house!!!! These little Envi heaters are a wonder - so worth the money because they are powerful and energy efficient. And you hardly notice them on the wall. I couldn't be happier - thank you eheat.com!!!

  12. Great heater for bathrooms

    Posted by Ilie S on 10th Nov 2018

    Heater does a really good job. It's installed in a small bathroom and keeps the space toasty warm. It's silent, cool to the touch, attractive, unubtrusive - and a fair price for an excellent product. Highly recommended.

  13. Heaven to have a warm closet to get dressed in

    Posted by Jenna Mahoney on 8th Nov 2018

    My upstairs heat is kept very low because there are only two of us in the house now and we like a cold bedroom anyway. We have a walk in closet and it's COLD in there...but not anymore! After installing (hardwired)this heater, it's heaven in that closet and that's where we get dressed now. This closet has become my favorite room in the house LOL.

    It is very much a cost savings to have this heater running because the thermostat for this floor can be turned way down now and we still have heat just where we need it.

  14. Envi heater # 4 and 5

    Posted by Jim on 4th Nov 2018

    One of the best products I have ever purchased. A great supplemental heater for a room that needs a little more heat to make it comfy. Running two heater continually over a winter period without any noticeable increase in electricity bills. Have used these units in Michigan, Virginia and Delaware. Thanks for making a great product. Jim

  15. We own 8 of the wall/plug heaters

    Posted by Elizabeth on 4th Nov 2018

    Very easy to install. Fit just about anywhere. Really nice long cord.They take up little space. We put them on outer walls to supplement our furnace at home. We have rooms that were added to the house and the furnace does not reach. The electric heaters in these rooms were too expensive to run.Now we just use the eheat envi heater. We also use them to heat our vacation home and vacation travel trailer.Great product!

  16. Purchased a 2nd heater 1 year later.

    Posted by Jon on 2nd Nov 2018

    I purchased an Envi plug in heater last year for an upstairs bedroom. We live in North Dakota so weather can get bitter cold and our upstairs bedrooms get chilly. The supplement heat works very well. I didn't notice any increase in the electric heat bill. This year I purchased another unit for an unheated basement bathroom. If u have a room that needs a boost of heat I recommend it. Wall above heater gets warm but I can still touch the wall with my hand. Heater shell not hot at all. No noise output at all from the heater. I have had no problems with either heater and they were very easy to install.

  17. A good specialty heater

    Posted by Charles W Fitzgerald on 2nd Nov 2018

    I have bought eight or nine of these heaters, for two different houses, in the last 4 years. Not only are they great for any room but they are especially good for trailer houses, older houses with inferior wiring and sheds with lightweight wiring run to them.
    The low amperage draw on these heaters make them much safer and much more energy efficient than a fan-driven 1500 watt heater. plus all of the energy consumption goes straight to making Heat without having to drive a fan.
    My primary use for my heaters are to keep the central heating unit from kicking on so much.
    However if I am gone for an extended length of time, I can run these heaters and a ceiling fan in each end of the house with the central unit off.

  18. Easy Peasy

    Posted by Valerie Kauffman on 2nd Nov 2018

    Just installed my 4th Envi Heater and 1 to go. I put 3 in a large basement to keep it comfortable without using the wood heat. They take up very little wall space, super easy to install, and I don't have to worry about my grandchildren getting burned or my pets. And no NOISE! Love, Love, Love them!

  19. Our Second Purchase

    Posted by Anne M on 2nd Nov 2018

    We purchased this one for our upstairs bedroom, as we don’t have many heat runs upstairs. I feel safe running this at night. It is very quiet and has only a small light indicating that it’s on. Our first one is at our seasonal cabin. It helped extend our season by warming up the cabin and maintaining heat overnight. Our electric bill barely increased. I like that it’s made in the USA.

  20. Great wall heater

    Posted by David W. Perkins on 19th Oct 2018

    This is our 2nd Envi wall heater. They work great in our bathrooms up at our lodge on the Grand Mesa.
