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. Takes the chill off without using propane!

    Posted by SunnyID2 on 17th Sep 2014

    We bought two Envi heaters for the main room of our 1155 sf home, which has an older, very inefficient propane furnace system. Rather than spend $$$ this fall to upgrade the furnace, we installed two plug-in Envi heaters in the LR-kitchen area. One is on a programmable thermostat, so comes on early am to start taking the chill off.
    The second heater rarely comes on, as the first heater usually suffices to get temps up to tolerable (mid 60's) till the coffee and daytime sun warms us up.

    We're looking forward to seeing how the heaters perform when the winter weather really sets in. For now, our filled propane tank has not yet been touched; hopefully we won't have to fill it again till near winter's end!

    We also ordered a third heater to be installed soon in an insulated outdoor shop storage room- should keep the temps above freezing for our small business supplies! We'll be ordering again if we need one in the larger workshop area.

  2. Bought 3

    Posted by Alice MM on 17th Sep 2014

    I just added 2 to the one I bought 3 years ago. We heat with a pellet stove for economy but have a few chilly spots in our home. These heaters are perfect for that. One in the bathroom, and one in each kids bedroom upstairs. Keeps everyone comfortable. Easy to install and reasonable to run.

  3. Very pleased

    Posted by Unknown on 16th Sep 2014

    I just purchased two Envi wall heaters and will be using one in a chicken coop and one in a laundry room. The shipping and packaging was excellent. It was innovative to use the packing frame as a template. Installation was a snap. I have not turned them on yet but with temps going into the 30's up North they will be working soon. I will update review after they have been on for a couple of days.

  4. Better Than Expected

    Posted by Ted on 15th Sep 2014

    I just installed my first unit and it looks and seems to be performing great. We are still "testing" to determine if we need a second unit.
    The installation went pretty smooth and we really like the fact there is no fan blower noise.

  5. Highly recommended

    Posted by Carol on 15th Sep 2014

    I bought two of these last year for my home and found them exceptionally efficient and effective. So I bought two more -- one for our vacation home and another for the wood shop, which has had no heating and was impossible to use much of the winter. It hasn't been that cold since it was installed, but on the days it dropped below 40F, the entire building (about 500 sq ft) was toasty warm. I have been recommending them to my friends, and at least two have bought heaters this year.

    My wife does a lot of horse shows and the trailer had a loud, inefficient heater in it. I replaced it with this unit and was absolutey amazed by the heat it put out. Fits in a two inch deep recess and does not get in the way. Greatest heater I have seen in a long time. Wish I had had one years ago.

  7. Seem to work great

    Posted by James on 11th Sep 2014

    I Know friends who use the exposed ceramic-plate heaters with success, but was always nervous about how hot they got to the touch. Its September, so we're not into cold season yet and therefore this is a partial review. Got the 3 heaters promptly- and they were a breeze to put in. I read several reviews that said there was a "smell" when first turned on. This is true, but its that new-heater smell. I ran them for a few hours once installed, and the odor is all but gone. As for performance, once turned on- I could feel a solid "draft" of heat coming out of the top of the units. Casing stayed perfectly cool, and top was only warm to the touch. (They are in my kids rooms, this was important). They seem to work exactly as advertised. These will allow me to turn off the bedroom-zone of my oil furnace at night. Satisfied.

  8. Just What I needed

    Posted by Franklin on 10th Sep 2014

    My basement apartment had no heat at all. I a total of five heaters and hey work fantastic and I like the idea that the only use 475 watts compared to the ones I used to have that used 1500 watts.

  9. Best electric heater for small spaces on the market.

    Posted by Walt Quade on 3rd Sep 2014

    I have been using ENVI heaters for all my small and tiny houses for the last 3 years and no one comes close to matching their efficiency and cost.

  10. impressive heater

    Posted by Dennis J. Colorado Springs, CO on 3rd Sep 2014

    I was extremely pleased with the appearance of the heater, the ease of installation, and it's silent operation. Have only operated it for a short period of time for testing, but it generates a great deal of heat for it's size.

  11. Exellent Heater

    Posted by Ron F. on 3rd Sep 2014

    Excellant quiet heating unit in a beautiful designed case. Although not yet cold,tried unit and room heats up nicely.

  12. a great heater

    Posted by Unknown on 3rd Sep 2014

    I purchased three of the units to heat my cottage on the days when it gets a little cool.

    Last week we used the heaters when the temp dipped at night to 48 degrees. The heaters worked much better than the simple space heaters we had before and they raised the temp up to 68 degrees when we had it set on the medium setting. The heat was evenly distributed throughout the cottage. We felt very cozy.

  13. So far so good.

    Posted by Serpico on 3rd Sep 2014

    Only had it for a couple of weeks and it is not the weather yet to use it. Tested it and it put out a decent amount of heat. I like the design and ease of the installation and it looks good and does not stand out lie the other heaters that I used before.

    So I will be getting 2 more heaters in the near future.

  14. It's not winter yet, but hopes are high the heater will serve me well.

    Posted by Diane Brown on 2nd Sep 2014

    I have two new heaters and have installed only one of them so far. A quick test proved it does make heat, but since it's still warm where I live, I won't know how satisfactory it will be until the "real" winter arrives. Meanwhile, I'm thinking about where I want to place the second heater. Fortunately, the installation was very do-able for me alone (75 year old woman).

  15. Waiting For Cold Weather

    Posted by Bill B. on 31st Aug 2014

    The installation process was very easy. Using the template you know every thing will be square. I'm waiting for the cold weather so I can be able to review your claims. If possible would you please ask me again November 15, 2014. Some items you may want to include in mounting are: Philliphs head screw driver; stud locator before mounting to wall preset a pilot hole prior to installing the threaded groumet. Other wise every thing else was well documentated. Thank you, Bill

  16. As Good As Advertised

    Posted by Gil on 31st Jul 2014

    Heating costs slashed by 2/3rds. Five plug in units scattered throughout a typical 3 bed-room ranch formerly heated by oil. Every manufacture claim and costumer testimony validated by my own experience. I couldn't be happier.

  17. Excellent

    Posted by Thomas Carraher on 29th Jul 2014

    I bought one now due to the summer savings. We have had some very cool nights here in Ohio this summer so when it went down to 47 the other night I left it on med setting and it worked wonderful. Fairly easy to install even in the close area I located it. I plan on buying another shortly for my attached garage.

  18. Best Heaters Ever!

    Posted by Lindsay C on 22nd Jul 2014

    We ordered one for my son's nursery last month and it is THE BEST heater we have ever had! So excited to have 2 more in the house! Thank you!!!!

  19. Great product for what it says it does!

    Posted by Mark on 19th Jun 2014

    bottom line: the units are space, energy, and cost efficient; completely silent and unobtrusive; ability to run safely when no one is at home; has several fail-safes.

  20. Satisfaction Supplied

    Posted by Jim K on 3rd Jun 2014

    I saw the ad for this heater in a magazine. Due to a recent renovation, I was without heat in my main bathroom. Before purchasing, I watched the installation video on line. The video is an EXACT display of how easy it is to install this product. I was amazed that the item shipped the SAME DAY that I placed the order. I don't even get that kind of speedy service from Amazon!
    Easy installation and works Great!
