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. The Envi Wall Heater

    Posted by Vicki on 11th Dec 2017

    We purchased 2 of these heaters for our sun room because it is hard to heat due to high ceilings. They do a fantastic job! We are very happy with them.

  2. Returning customer

    Posted by william on 11th Dec 2017

    I am slowly am replacing the old style different brand panel heater purchased years ago. The newer ones are so much better and no bad wires in back of unit or cracking as in the old ones.

  3. I love it

    Posted by Carrol Romero on 11th Dec 2017

    It does get cold in Southern Calif, especially in the desert areasin the winter! The HH1012T plug in model is perfect for the rooms facing away from the sun that get chilly. I bought my 2nd one for a family member that "envied" my Envi !! Just wish you also had a half size model for extra tiny bathrooms!

  4. Great Christmas present!

    Posted by C.J. Romero on 11th Dec 2017

    I bought new one for Christmas 2017 present for a family member that said their bedroom was too cold in the winter. This will be the 2nd one I purchased. The previous one is a plug in and was put in the coldest (north facing)room in our house. It starts warming the whole room immediately! Everyone that sees it and feels the heat wishes they had one! I will never use my unsafe space heater (1500 watts) again!

  5. more heat output than I expected

    Posted by e hoenshell-watson on 9th Dec 2017

    truly perfect heating companion to cold spots. i bought two, but the one i installed has done the job of silently warming and maintaining the heat in a large room always drafty and cold. it has equalized the temp making it comfy and unobtrusively effective.

  6. Exactly what I needed vs 1500watt space heater

    Posted by Jenn R. on 8th Dec 2017

    I am currently using 2 Envis's for a ~300 sq ft renovated barn that I turned into my office. Was using a 1500W space heater that was sucking electricity and did not heat the room evenly. It also kept tripping the breaker, which was annoying. This product was incredibly easy to install and had my space nice and cozy within a day. Was pleased to see the temp has remained constant and am looking forward to seeing some savings on my electricity bill. Would definitely recommend this product.

  7. very pleased with the heaters

    Posted by d lloyd on 8th Dec 2017

    I am very pleased with the heaters they are easy to install, operate quietly and do a great job keeping our two main living spaces warm. We have a fireplace with a insert that we use as our only other heat source due expense of the cost to operate our central heat pump running. Couldn't be more pleased and look forward to waking up to a not so cold room every morning.

  8. great, safe product.

    Posted by Bob in Tennessee on 8th Dec 2017

    I purchased an Envi heater to try in my 480 sq. ft. sunroom. So far in 25 degree overnight temps. it has kept the room at 50 degrees. Very happy and will be ordering another to add to it. Makes me feel very safe to let it run 24/7. Also out of the way and pet friendly.

  9. So far love the heaters

    Posted by Frank on 8th Dec 2017

    Packaged well, easy to install, well throughout products. I have only had them in use for about a week but I love them so far. Have 2 in a 30 x 18 second floor bungalow room. Keeps the room quite comfortable with temps in the 30’s now.

  10. Love it

    Posted by Donna on 7th Dec 2017

    These heaters were as easy to install as you claimed they are. I did it before my husband came home from work and believe me, I was a little nervous at first. Using the template was easy and accurate.

    We couldn't believe that they arrived so quickly either.
    They arrived 4 days after we ordered them!

    The heat is even and constant. No blasts of hot air or cool downs.
    So far, we are very happy with these heaters.

  11. Excelent heater for bedrooms

    Posted by Unknown on 7th Dec 2017

    I purchased two Envi Heaters. One for each of my sons bedrooms in our basement. Easy installation and they heat the rooms perfectly on cold days when the furnace won’t keep up. I only wish they had a numerical temperature setting instead of having to guess with the unnumbered dial. A minor complaint, that is worked out with a couple of days to adjust it so that it’s just right. I would highly recommend this product!

  12. Great heaters

    Posted by Dean on 6th Dec 2017

    We had our first Envi Heater for our enclosed un-heated back porch. We live in eastern PA and the winters can be cold and windy at our house. Even on the coldest nights the heater kept the porch ( where we have our washer) at a very nice temperature. No need to worry about pipes freezing. This year we purchased two more heaters, one for our main bathroom that was always chilly but is now toasty warm and the other is a gift for my parents who also have an unheated enclosed porch. They are currently using an old oil filled electric radiator to warm the area, this should save them a bundle on their electric bill each month. Oh yeh, it's about 10 minutes to install and have operating …. You can't beat that.

  13. Great product! Highly recommended!

    Posted by Russ on 6th Dec 2017

    Easy installation, foolproof in fact. Took about 5 minutes to install, heated room up nicely while staying cool to the touch. New smell "burns off" in a few hours. Easy to use and understand controls.

  14. warms a small room wonderfully!

    Posted by Bethany on 6th Dec 2017

    If you can be patient, this little heater is great! I have it in a guest bedroom with tile floors and gets cold in the winter - this little heater warms the room like it's never been warmed before and does not raise my energy bills

  15. Rave review

    Posted by very happy customer on 5th Dec 2017

    I have one I’m each bedroom and one by the back door (coldest part of the house). Love them. No noise and keep the area warm, as advertised. Just bought my 4th one. I rave about them to anyone who will listen. Just wish you would offer a wall shield to go above them. Over time a small area above heater stains. Not from excess heat but, rather, from dust. Washing the area does help. I am going to look for a solution to put up after I paint next time. However, I consider this a small price to pay for this great product

  16. Great Heater

    Posted by Mike- on 5th Dec 2017

    This is a great heater, it is compact and it heats really good, and it looks good on the wall, It heats better then electric fire places,and heat pumps. I would recommend this product to any one who wants a nice warm home. Considering buying another one for my downstairs.

  17. Wish we'd had these years ago!

    Posted by Joan on 5th Dec 2017

    COLD NH winters made using our 12 X 20' dining room addition a rarity September - May. The cold from the unheated basement below seeped up through the floor and -- no -- there were no casual conversations around the table after meals! We recently replaced strip heating in this room with two Envi heating units located on opposite walls/opposite ends. It's toasty warm now for the first time ever. The look of the heating units is unobtrusive and clean. We're using the plug in models, feeling that we may be able to get by with just one in this location and will utilize the 2nd in another part of the house.

  18. wow !

    Posted by LeRoy B on 4th Dec 2017

    These are by far the best, both are in use. Great, easy to install, very nice design and made in the USA!

  19. 5 minute installation

    Posted by Carol Walker on 2nd Dec 2017

    We purchased an Envi-Heater several years ago and loved it. We decided that when our heat pump died, we would install some envi-heaters and split unit air conditioners. Our heat pump died, but with the provided template, it took all but 5 minutes to install these heaters! No running fans and safe to the touch for my animals and ourselves!

  20. One of the best electrical heater on the market

    Posted by Martin Scheulin BC Canada on 2nd Dec 2017

    good customer service, nice design ,easy to install and safe for everybody really good product.
