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. Warm at last

    Posted by Catharine on 24th Nov 2015

    Eheat was simple to install, worked as described and has been a boon to me as it warms a very cold bathroom. My one observation is that I cannot see the gradations on the gauge for upping and lowering the heat. So I colored them in with a permanent marker.

    Thanks for a lovely product.

  2. So far so good!

    Posted by Keith Andrews on 24th Nov 2015

    I decided to buy one of these heaters for my Daughter's room because we were using a Fujitsu mini-split system just to heat her room at night. If anyone is familiar with these indoor/outdoor combination units, they will know that although they are very efficient in their method of heating a room, they do use a lot more electricity than a small 500 to 1000 watt space heater. Since we were only looking to heat the one room overnight on cold days, we couldn't justify spending the extra money in our utility bill just to run the one wall unit. This Envi heater proved to be a very affordable and efficient way to heat the room. Like others have said, based on its design and the output, it does take a couple of hours to bring the room up to a comfortable temperature, but that will depend on the size of the space as well as the insulation factor of the home. We have a very new, well-insulated home with R30 walls and an R60 ceiling, so the degree of heat loss in the room is very low. I have considered buying a new Fujitsu floor unit when we finish the bonus room over our garage, but due to the expense, we may now just put a little more money into insulation and instead buy two of the Envi units to heat the 12x20 room. The cost would be around $4,000 for equipment, installation, and electrical of the Fujitsu versus around $300 for two envi units. For the little amount of use the room would get, the Envi units would probably do the trick. I will update my review once the harsh Maine winter temps and wind hit full force, but I have high hopes for the Envi unit based on the experiences of other reviewers.

  3. Problem Solved

    Posted by Willingtowrite on 24th Nov 2015

    We weathered one winter in our 3-story-single-zoned-furnace home and found the bedroom on the top floor always hot and basement always cold. We would use the furnace as sole source of heat & turn it up to be able to use the basement for more than an hour which made where we sleep unbearably hot. We thought we were going to have to spend $$$ to have a 2nd zone for the basement and stumbled upon eHeat.com instead. We bought 3 envi heaters for the 1,000sf basement and now find it's the coziest area of the house. The dials alone are enough to use as 'thermostat' once you "dial-in" where to keep the setting. We bought one of the programmable plug-in thermostats for the largest area & it is helpful primarily for turning up the heat during times when we're usually downstairs. Our measure of cost to operate in our state (Utah) in cold weather at around 7,000 ft in elevation is $15-$20 per month, per heater. Overall, the Envi is a very economical solution to our problem.

  4. Exactly what I was looking for.

    Posted by Unknown on 24th Nov 2015

    This heater is great. We are using it to supplement heat in a 12x12 bedroom addition off a mobile home. I love the quiet operation, the built-in thermostat and mostly how the unit does not get hot, unlike other electric panel heaters I have owned, which makes it feel a lot safer for use. All in all a great product

  5. Quiet, warm. comfortable heat.

    Posted by Michael on 24th Nov 2015

    Installing the heater was simple and easy. The heater is so quiet you do not know it is even in the room. It uses one-third of the electricity my old heaters used! Very comfortable heat - similar to a wood stove. But without the ash! I would highly recommend to others.

  6. Office

    Posted by Keith on 24th Nov 2015

    I bought one and its great and keeps me warm, not so hot or cold like any other unit just the right temp. It's also very easy to mount on the wall.

  7. Cold areas are gone!

    Posted by Finn Runyon on 23rd Nov 2015

    We live in a hacienda style home in Taos, NM. At 7000 feet we get very cold nights during the winter months, and there were four sections of our home that were constantly cold at night. During the day we get great solar gain and we have little need for heat, but at night these four Envi heaters have made what was pretty unbearable frankly delightful! They are unobtrusive and really attractive to look at!

  8. Envi heater

    Posted by Carolyn Horton on 23rd Nov 2015

    This heater has been the best heater product I have ever bought. It keeps my little apartment toasty and warm. Thank you.

  9. Very pleased with the Envi heater!

    Posted by John Laurenson on 23rd Nov 2015

    We are very happy with the Envi heater. We got it to supplement the heat in our cabin and it performs as promised. It is safe with pets, has no open flame, and is exactly what we wanted!

  10. easy install and great product

    Posted by Unknown on 23rd Nov 2015

    I bought the envi heater for a hallway that has no heat source of its own. The envi provided the needed heat and was a great fit in the space.

  11. Great looking heater

    Posted by Dean on 23rd Nov 2015

    We have a small unheated enclosed back porch. This heater is very easy to install and looks great. It only took about 15 minutes to have it up and working. It seems to put out a fair amount of heat. I would recommend this product.


    Posted by Unknown on 23rd Nov 2015

    We bought ours last year and they work great, one in the bathroom and one in our bedroom. Excellent product at an economical price.

  13. Works best in small room

    Posted by LL on 23rd Nov 2015

    I bought 2 plug in units. The one in my bedroom works great. Takes the chill out of the air. It works even better when the door is closed. The wall is hot (as normal) and I do keep it on all the time. When I leave the house, I lower the temperature.
    The one we are using in the living room is not nearly as effective. Maybe it is b/c the room is larger and it opens into the dining room. VERY pleased with bedroom unit.

  14. Basement Heaters

    Posted by William Limbrick on 23rd Nov 2015

    I bought one and it worked so well I bought another one a week later. It's also very easy to mount on the wall.

  15. Easy installation & ready to go

    Posted by Unknown on 23rd Nov 2015

    This product was easy to mount to the wall and get started. The heater produces heat well. We are using it as primary heat in the bedrooms and are using our ceiling fans to bring the heat back down.


    Posted by David Francum on 23rd Nov 2015

    I ordered 2 in Feb 2015 and immediately fell in love with them. I installed one in our bedroom and one in our TV Room/Office. We just received our second order on 2 more units. I have placed one in our Kitchen/Breakfast room approximately 20 X 14, I will be adding to this one as soon as we can afford 2-4 more. The second one I installed in the dinning room/living room. Unfortunately, we own a 20 year old double wide and live in the mountains of Western North Carolina. We are retired on a fixed income so it takes about 6-8 months to save enough to order 2 more at a time. We still have to use our regular electric (heavy electric eater) to supplement when it gets down to the 20's like now...but, not to worry. We will get the addition 4 installed by next winter! When the outside temp drops to the 30's the Envi Heaters do a fantastic job!!! We luv em. Thank you for inventing these. We want to go solar and wind and with the low electrical draw these will mean we can get by with a smaller set-up. Again, thank you and God Bless!! David-A VERY SATISFIED CUSTOMER!!

  17. Awesome heater

    Posted by Oscar on 22nd Nov 2015

    At first I had doubts that this heater will work as i wanted to. after I installed it which was very easy, I couldn't believe how much it heats,
    I haven't gotten my bill to see a difference but Im looking to buy two more heaters.
    Great product keep up the good work.

  18. Takes care of the cold spots in our house

    Posted by Marie Loup on 22nd Nov 2015

    Love the 2 Envi heaters that we purchased for two rooms that don't seem to ever be warm enough in our old house. If I had a change that could be made it would be that they could be smaller in size and not take up so much of the bottom half of the wall. Other than that, they work great!

  19. Love it!

    Posted by Heather on 20th Nov 2015

    Really pleased with the heater. It was easy to install, looks great and, best of all, makes the room cozy. Thanks!

  20. This heater is the second one we have bought.

    Posted by Unknown on 20th Nov 2015

    We have 2 now. They cut our heating bill in half. I can enjoy my home without making it unbearable for my husband and son. It keeps it warm without getting so warm that they suffer. I have told many of my friends about these heaters. I recommend to anyone.
