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. Great for Galveston winter

    Posted by Jess in Galveston on 27th Feb 2015

    I have tried different space heaters over the years and most were scary, as the cords would overheat. So I bought an Envi heater last year for our Galveston Victorian house. I was very pleased with the heat and safety. I have since ordered several more for other small bedrooms and the parlor. Now we can lower the thermostat on our central and have true zone heating where we need it!

  2. The Envi fit the bill.

    Posted by BOBS on 26th Feb 2015

    I heat my Home with a pellet stove and the Master Bedroom and Bath( which is currently being remodeled) is on the far end so I wanted to incorporate a sleek looking quiet heater in the Bathroom. The Envi fit the bill. I temporally set it up in the other bathroom just to see if it was what I wanted. Believe me it is! It's not a blast furnace. You set the temp and leave it there and you will walk into a warm Bathroom. I don't know how it will work in a larger room. I'll try that next. I do plan on getting another one.

  3. As Expected

    Posted by Bill Wong on 25th Feb 2015

    The amount of heat produced is adequate for the bathroom (northern California locale). Appearance is good, very clean looking. Easy to install. Cord outlet is on the right bottom, in case that matters.

  4. 5 Stars!!!

    Posted by Unknown on 24th Feb 2015

    Our laundry room is in our basement, with a drafty door to the outside. It gets colder than the rest of the house. We had purchased the Envi at another home & had been very satisfied. So we purchased another! We have not been disappointed. We set it on approximately half, closed the door & let the Envi do the rest. The room is now as warm as the rest of our house. Plus we don't worry about the plumbing in there as well. We have left it on 24/7 with not a worry.

  5. have the texas summer heat in the winter!

    Posted by robert anthony martin on 24th Feb 2015

    i built a texas room [family room/media room]
    and had to decide how to heat it in the winter.
    i purchased an envi wall mounted plug in electric panel heater and have used it for over three seasons...it is very stylish, noise free, well designed and works efficiently year after year... a great product for the price and was very easy to install! this unit is very highly recommended to buy!


    bargain bob in katy texas..

  6. So glad I found this!

    Posted by Erin on 24th Feb 2015

    We have a ~200 sq. ft. basement room with a door to the outside, stairwell to the upstairs kitchen, and door to the laundry room which is off of the garage. With basically no insulation, and cat doors in 2 of the 3 exits, that is a lot of space for heat to escape to. We bought two of these for the room and after only doing a plastic window treatment, they are keeping the room at a comfortable temperature. Previously we were using a space heater that had to be unplugged every time we left the house which caused the room to get cold again. With our new heaters, I can leave them on 24/7 and not worry about getting cold or any safety issue, especially with a baby on the way. I would recommend these to anyone, but make sure you accurately measure your room size and draft leaks so you purchase the right amount of heaters.

  7. New Enclosed Patio

    Posted by Unknown on 24th Feb 2015

    We recently enclosed our patio and wanted to find a heat source which would allow us to use the patio during the chilly Georgia winter. The Envi wall heater maintains the patio temperature 20+ degrees above the outside temperature on cloudy days. Even more with added radiant heat on sunny days.

  8. Superb heater, great design, great product

    Posted by Unknown on 23rd Feb 2015

    We're very early in the usage stage, having only received and installed the heaters 48 hours ago, however they've turned two very cold bedrooms in our NYC apartment (with no other heating source at all) from ice boxes (I am not kidding you regarding one of the bedrooms) to nice and warm spaces. We need only to put the heaters on settings 2/3/4 to get a great temperature. The rooms are very small (90-100 sf) and medium (150-170 sf) sized and we're planning on getting two more for similiar sized rooms in the apartment. Very easy to install, great design and so far doing a great job.

  9. Warm at last!

    Posted by Maria on 23rd Feb 2015

    We've lived in our current home for almost 5 years. The back room (family room) is not well insulated, with no source of heat except an in-wall unit which is very ineffective. I received the unit last week. It was unpacked and installed within 20 minutes. We've been warm and cozy ever since.

    Don't expect instant heat up,( especially in a large space). You'll start to feel the difference after the unit has been on for a little while (1 -2 hours).

  10. Fantastic Features on the Envi Heater

    Posted by Katie on 23rd Feb 2015

    I absolutely love the features of the Envi Heater. The fact that it was super easy to install, cool to the touch in a day care environment, completely quiet and throws off quite a bit of heat.

  11. Does the Job

    Posted by Donald Clarke on 23rd Feb 2015

    I installed a wall-mounted electric heater in February 2015 in Colorado Springs, to heat two small well-insulated rooms, about 130 sq ft altogether. It does the job with the temperature control only half-way up!

  12. Works as advertised

    Posted by Unknown on 21st Feb 2015

    This heater was easy to install, looks good and puts out heat.

  13. keeping my mother-in-law's room toasty

    Posted by Jim on 20th Feb 2015

    During this brutal winter, my mother-in-law has been cold all the time and at 91, this was not a good thing. I put the Envi heater in her room and the room was toasty warm in no time. It is silent so no problem keeping her awake at night or nap time. It takes up almost zero space in the room so no need to rearrange furniture or anything. So far so good.
    We'll have to wait and see if it increases my electric bill but it has been so high lately, I probably won't even notice. Small price to pay her warmth.

  14. No more chilly bathroom!

    Posted by Christopher Ruch on 20th Feb 2015

    Bought this unit for our master bath. We only have one small heat register in this bathroom and it was never warm enough in the winter. Got this just in time for our record breaking low of 2 degrees (in southern Virginia) and was amazed that the bathroom stayed comfy. Very satisfied. Also, excellent packaging (with wall template) and good instructions.

  15. Best heater for RVs yet!

    Posted by Michael on 20th Feb 2015

    I had seen this product before and was a little sceptical as to how it would work. After getting one to try, I am very impressed and can sleep without the click on and off of an oscillating heater. It heats my 38ft Rv without the furnace even coming on. I have shown it to many others and they too were suprised at the heat output at a low setting. Will definitely be getting another. Thanks for provding such a great product.

  16. Love it!

    Posted by Unknown on 18th Feb 2015

    Great product, fast shipping

  17. Exceeded my Expectation

    Posted by Unknown on 18th Feb 2015

    Easily heats my basement office, especially with these single digit temperatures. Easy installation, and nice cabinet. Fast delivery. Overall, I am very pleased with the heater, and the overall experience.


    Posted by Pete on 18th Feb 2015

    Heaters work great, I'm buying two more for my sunroom. The eheat uses 1/3 of the energy of the heaters I was using.

  19. Great Heaters...keeping my folks warm

    Posted by Aimee on 17th Feb 2015

    I love the heater and the new design. I still have the original one I bought back in 2005....love these wall heaters.

  20. GREAT Heater that uses very little energy

    Posted by John Curran on 17th Feb 2015

    We live in Florida but two of our bedrooms were colder than the rest of the house. We also use solar energy to offset our electric bills. When we saw how little energy this uses we had to give it a try. The 1st night our daughter actually said her room was hot.

    We just purchased another one today to replace a heater in my office that used 1500 watts.
