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. Perfect Supplemental Heat for 1830s Farmhouse

    Posted by Regan S. on 8th May 2018

    Our house was built almost 200 years ago, and there were a few cold spots that needed heat but we didn't want to rip things up to install more radiators, and these have been the perfect solution.
    No more cold spots, and these even work well on their own to take the chill out of a cold, damp day when it's not worth running the whole heating system.
    They blend in seamlessly with the walls and decor, and we always get compliments on how sleek they look. These were exactly what we needed; they do a great job of heating silently for pennies a day.

  2. Best heater I ever bought!

    Posted by Cynthia B. on 21st Apr 2018

    I should have listened to my sister along time ago! She purchased three of these to supplement her creaky old heater till she could get a new one and they totally rock I finally bought one and mine is awesome quiet efficient and toasty warm

  3. About time! Astounding heat output for the cost!

    Posted by Corinne Guilmain on 12th Apr 2018

    Wow. I love this heater. I only have one unit but I plan on buying at least several more. I put together a monthly heating bill for my house in Vermont. It looks like this. The floor plan here is open concept, long, with 3 bedrooms, a sunroom with all 3 sides in windows. This measures at 41 feet wide and 27 feet long. There is an attached enclosed room with no heat that measures 24 feet wide and 27 feet long. It is 48 degrees outside. The attached room with no heat measures at 62 degrees and the house measures at 71 degrees. There is a wood stove that is barely staying alive and hardly any heat is coming out of it. This is so if this experiment fails, I don't have to restart the stove. One unit is placed centrally in the house. So the figures I've given you are absolutely, in my opinion, astounding. But I have a question. How much is all of this going to cost? I just started so I have no idea what the cost is. But as far as the heat output goes, oh my gosh. There is a possibility that I won't be lugging in wood all winter long! I have a bad back and going through another winter like this is not an option for me. Now comes along eHeater to save the day. I am dancing a jig. So let's get to the costs so far. I have calculated a monthly figure of $350 to heat this place. This includes wood and propane. I will have to wait for the new figures to come in to see if there really is a savings here. The heater is on all the time. I never have to worry about it. It's not like loading the woodstove and counting down until the next load. I just leave it on. So now you have some figures to work with in deciding if this heater is right for you. It's right for me and I would definitely recommend this product. I don't usually write reviews, but this product is so good that I want to pass it on and congratulate the people who invented this heater. Oh, I forgot to mention that installation is a snap. You couldn't have made it any easier. Bravo!

  4. Warm, warm, warm.

    Posted by Susan Rebelski on 10th Apr 2018

    This is an amazing little heater. Until a family member recommended it our bedroom was freezing. Within 2 hours of plugging it in the room had lost its chill. Hit 68 by bedtime. Also it hangs on the wall so no loss of floor space. Safe for small children.

  5. Great choice for electric-only heating.

    Posted by Frank Hetherington on 9th Apr 2018

    I've move 100% to the Envi heaters. Their efficiency and effectiveness is vastly improved over the old style electric baseboards. I don't have to worry about the grandkids or curtains getting burned by the baseboards. And, they presented the opportunity to avoid a costly installation of an oil or propane forced-air system. The units with the AC cord install in about 4 minutes. I no longer have cold spots around my home.

  6. A great heater

    Posted by Julie on 8th Apr 2018

    We have only had them a month but we really like them. So far they have done what we were told they would do. Quiet heat!

  7. Excellent Heater, Exxellent Value

    Posted by Emit on 22nd Mar 2018

    I have used these heaters (I own a total of 5) in a business application for 5 years. They operate completely cool to the touch while providing an effective heat source. They are easy to clean and the design is non intrusive. Highly recommend!!

  8. Love this Heater

    Posted by Lynn N on 22nd Mar 2018

    This heater is easy to install, looks good and works like a champ. I have two of them. I no longer worry about grand children around a freestanding heater.

  9. Stylish economical space saving heater

    Posted by Anthony Piccini on 18th Mar 2018

    Works well and blends in with the rest of the surface, does not get in the way of furniture. Gives off a nice inviting heat. Makes the room very comfortable. Surprisingly good.

  10. Compact but a lot of warmth for Tiny House

    Posted by Mike P on 9th Mar 2018

    Got as a secondary heat source for our 18’ Tiny house (use wood as well). Keeps the house nice and warm when the fire goes out and very quick to get up to temperature.
    Would definitely recommend to anyone with a tiny house who lives in colder climates as secondary heating!

  11. Nice space saving and clean line heater

    Posted by Phyllis on 5th Mar 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.

  12. Much better than the flat panel heater I bought last year

    Posted by Joseph Rosowski on 25th Jan 2018

    The fins on this heater radiate much better. Plus it has a thermostat

  13. The best

    Posted by Gabriel Torres on 22nd Jan 2018

    This product is easy to install, silent and very efficient. The electricity consumption is much minimal. I recommend ????

  14. Great Heater

    Posted by Rich M on 18th Jan 2018

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

  15. Clean, quiet and efficient heat for my Tiny Home

    Posted by Gail R. on 18th Jan 2018

    I am so happy with this heater! I read many reviews and watched a Tiny Home video recently by Deek Diedricksen from RelaxShacks.com to see how easy it actually was to install. I do not regret this purchase. I installed mine in my 144 sq. ft. tiny home in minutes and it heats this space just fine.

  16. Best panel heater on the market

    Posted by Bill L on 18th Jan 2018

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

  17. One of the best electric heaters for the money

    Posted by Gary Roberts on 17th Jan 2018

    I bought two for my well insulated shop(10 x 30) but installed one in an unheated upstairs bedroom and the other in the shop. Five minute install.....easiest ever. Built in thermostat a plus. We had about a week where the outside daytime temperatures did not get above 12 degrees and nighttime it was below zero. The bedroom heater successfully made that space very comfortable and held the temperatures at 65 degrees. The shop was a much larger space but with a little help from a small wood stove that went out sometime in the early morning hours the temperature ranged from 50-54 degrees by 8AM. I will be adding a couple more to the shop in the near future and will get rid of the wood stove.

  18. Keep whole house warm with 3 of these

    Posted by Amie on 17th Jan 2018

    I have a 1500 sq house that is well insulated and keep my entire home in 20 degree weather at 70-72 degrees with just three Envi heaters,

  19. Exactly what we needed

    Posted by Amie on 16th Jan 2018

    My grandson’s room is the coldest in the house. It is a new build as of September 2017. His room is on the north side. He has a large window. We keep his door closed as the instructions state and his room is super cozy. I no longer have a wrap him in two pairs of pajamas and extra socks. It stays about 74 or 75 in his room and the thermostat is set at 69 to 70. Although his room is small. We do not have to worry about him burning himself or any of us either. Nor is there a lot of noise as it is very quiet. You cannot hear that it is on. I cannot forget to mention how super easy the install was. The box is a template and it went right on the first time. Highly recommend!

  20. Envi heater for our Laundry room

    Posted by Mrinal on 15th Jan 2018

    Had the Envi installed on Friday and I must say am very impressed with its efficiency. Quiet, no sound and surprisingly effective. We installed it in our laundry room as it’s furthest from our furnace so the vents aren’t as efficient and our housekeeper says she’s freezing.
    She says this heater is working well for her. So am glad I purchased it. Cool to touch and sleek. Thank you.
