Product Description

The envi Wall-Mounted Electric Panel Heater is one of the most efficient, stylish, and innovative space heaters ever developed. We have now introduced four new models, including for the first time ever, the envi Hardwired Heater - perfect for commercial installations. This model (HW1012T) is our hardwired version of the original envi heater, so instead of a cordset it has 16AWG lead wires (live, neutral and ground). This model also has a built in thermostat, but can also be hardwired to an external thermostat, timer or switch.


  • NEW - True Temperature-Controlling Thermostat. (Models HH1012THW1012T and HW1022T)
  • NEW - Wall-Sens(TM) Technology, safely cuts power to heater if it is removed from the wall. (All models)
  • NEW - Now rated for 475watts (10 - 13% heating performance increase) - all models.
  • NEW - Convenient Cordset storage inside heater to tuck away untidy power cord. (Plug-in models)
  • NEW - Hardwired models available, approved for commercial installation.  (HW1012T/HW1022T - with built in thermostat and HW1012N/HW1022N - with no built in thermostat)
  • NEW - Now CSA (Canadian) safety listed (All models). If you are in Canada, please go to www.eheat.com/canada and you will get FREE SHIPPING to any location in Canada!

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), savings of up to 50 percent on heating bills can be expected
  • Efficient - 100% Pure Convection Heating
  • Innovative - New Patented Stack Convection Technology
  • Safe for children, seniors, and pets - Cool-to-the-touch (90degF), 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. The envi heater finally answers the need for a legal and safe, hardwired electric panel heater. (Only on models HW1012T and HW1012N)

  1. Excellent Design. Bye Bye Gas Heater!

    Posted by Shawn on 17th Oct 2017

    I just installed two of these babies in my 350 sq ft cabin which gets pretty cold at night starting in October. I paid some professional electricians 1k to install them for me because I also wanted to add a dedicated breaker to my panel, so there can be more cost associated with the hardwired version, but having no electrical cord is nice-the heater looks great on the wall and it blends into the background.

    On to the performance; I am very comfortable at night with both units going at the half-way/medium setting. No noise, just a soft radiant heat. It is not hot to the touch even if I have it on the max setting-in a small cabin that is SO wonderful! I have two units going and they use 1/3 less wattage than my little ceramic space heater with a fan, and they put out 10X the heat & comfort. The envi is a revolutionary design that really is meaner and greener. I will eventually be hooking their breaker up to some dedicated solar panels. Bye, Bye gas wall heater-I'm ripping that out!

  2. Awesome !!!

    Posted by Tee Creighton Sr on 2nd Oct 2017

    I Installed 4 hard Wired Envi High-Efficiency Whole Room Electric Panel Heater in My Son's House and it was Easy and Quick.The Temperature Dropped to 33 degrees that Night and My Son said they Worked Great ! We are Ordering 4 More for Upstairs :)

  3. Very easy installation

    Posted by Dan S. on 22nd Sep 2017

    I needed to install heaters in the three bedrooms of the house I just sold, the buyer had researched and asked for these particular heaters to be installed, and I looked online at Home Depot's site to see what they sold, and wasn't impressed by the reviews on the import brands of heaters that they sold, so I decided to go ahead and install these, especially since there are American-made. When they arrived, I was impressed by the neat and efficient packaging of the product, the very clear and easy to follow installation instructions, and the overall design of the product. I installed the hardwire models, because of the buyers lenders requirements, but otherwise would've gone with the plug in the models. I only turned them on long enough to verify that they work, I haven't had a chance to try them in cold weather, but I expect that they should work quite well, being a convection type heater. I am planning to move to the northwest, away from the desert, and if I need heaters in my next house, I most likely will go with these, versus harder to install baseboard or fan forced in the wall mounted type heaters. Overall, these seem to be an excellent choice for heating individual rooms, and it warmer climates, could be used for the entire house, versus having a central heating system.

  4. Great Product for heating 300sf garage

    Posted by Mike on 14th Mar 2017

    I installed two units at the opposite ends of my garage which is 12X24 with a 18 foot (center)ceiling with one unit on an interior wall and one unit on an exterior wall and they maintain 72 degrees in the garage at 10-15 degrees outside. Units are simple to install and look great.

  5. Sleek and asthetically pleasing powerful heater.

    Posted by richelle on 11th Mar 2017

    I'm so happy to have found the Envi. This low profile heater was a perfect heating source for our new mud room. Due to its minimal depth it fits on the wall of a door swing. It heats our mud room evenly and operates silently. Highly recommend.

  6. amazing heater

    Posted by Allison Hughes on 20th Feb 2017

    very satisfied - only suggestion is make the hardwired cable a little longer. we were a little limited by this. my electrician friend suggested even another 12 inches would have been perfect. we made it work. Thank you!

  7. Easy Breezy Installation

    Posted by Anthony on 8th Feb 2017

    Easy to install, I had the hard wired version as I was replacing an old bedroom heater, the unit size covered the box of the past heater so I didn't have to modify the wall at all.

  8. Finally, reliable Heat

    Posted by Bob B. on 25th Jan 2017

    Our bathroom is 8x9 in an old house (94 yrs). It was heated by base board steam which never worked properly so we removed it. When we showered, we used the O/H exhaust/heater, so the room was basically cold most of the day during the cold weather.
    We had an electrician install a hard wire Envi heater on the only wall available(outside)and it works great.
    We are able to keep it on the lowest settings and the room is heated wonderfully....and quietly.
    It is stylish compared to normal space heaters. Thank you for a very good product,

  9. Finally warm!

    Posted by Finn on 18th Jan 2017

    This is the 5th Envi heater I have installed in our home. We live at 7200 feet in Taos, NM and our old adobe home had several cold spots that were hard to keep comfortable. This last heater went in the bathroom of our guesthouse which had an old 1500 watt blower/heater that was hard to control and quite noisy. This latest installation keeps the bathroom cozy and warm without the noise or high energy draw.

  10. great product

    Posted by Dennis on 23rd Dec 2016

    I've used one for a year, and couldn't be happier.
    It gives a nice comfortable heat and eliminates the risk of baseboard heat. It looks good and is unobtrusive, giving me more room to do the day to day.

  11. Measured Efficiency with Kill-a-Watt Meter

    Posted by Jack Langley on 18th Dec 2016

    Now that the 2 two units have been in for 2 weeks, I can talk about the efficiency.
    Since the convection design works so well, it appears that they are on less than half the time. I will have more data as time allows.

  12. Best heat for the money

    Posted by Pamela Bush Brisbin on 16th Dec 2016

    I have waited to write this review until the cold arrived in the Northeast, and it has. We had a problem heating a small bathroom in our home. It wasn't configured well for baseboard so we had to find an alternative. We tried an in the wall heater with a fan but it woke me at night and the heat wasn't consistent and it would get cold. And if heat can have a quality it was poor. Then we found Envi. Out bathroom maintains a consistent temperature that is consistently warm and comfortable even here in the Northeast. The heat quality is excellent and it is very quiet and has a low profile so it can fit almost anywhere. Great value too!

  13. Effective and easy to install

    Posted by Unknown on 5th Nov 2016

    Purchased 2 of the hardwired 120v units and they installed easily and work like a charm.

  14. Great product!!!

    Posted by C. H. on 2nd Nov 2016

    I installed it (HW1012T), hardwired, in a full bathroom that had not had a heat source even though it is a new house. Added a timer switch and works great. Bathroom size: 90 square feet.

  15. great heater!

    Posted by lila on 14th Oct 2016

    We have this in our kids room and I am so impressed! We have tried many floor space heaters and spent $$$ on heating costs in the winter. This heater is sleek, quiet and efficiently heats up the room on the lower settings. I wish we had found this heater years ago... could have saved some money!

  16. Great Product

    Posted by Fred W on 13th Oct 2016

    Installed easily, directions were easily understood. Turned it on and warmed the room nicely. Should say it is still fairly warm here at this time so I will have to wait for cold weather to give a final answer on this one. Really like the product at this point.

  17. Excellent supplemental heaters

    Posted by Steve & Terri S. on 9th Oct 2016

    We purchased 3 Envi HW1012T heaters for our seasonal cabin to supplement a central gas wall furnace. Very nice, clean design and overall high quality appearance and feel. Installation was simple and straightforward, even with hard-wiring. All operate very well and provide quiet and clean heat to rooms from 75 to 150 sq. ft. We'll likely purchase several more for our primary home.

  18. Easy install and operate!

    Posted by Gary Bishop on 20th Sep 2016

    Unit was easy to install and incorporate with existing outlet. Unit provides sufficient heat as advertised for 150 sq. ft. If you have a larger room you may want to consider multiple units.

  19. Very nice heater!

    Posted by TJ on 12th May 2016

    This heater was used to replace a 500 watt baseboard heater in a small bathroom. It works as described and is way better looking than the previous unit. Keep in mind that 475 watts is the equivalent of 860 watt light bulbs. So, if you are expecting a lot of heat, you will be disappointed. It is best suited for a small room or for supplemental heat. If you purchase the hardwired model, the wiring compartment is very small which makes the installation a little tedious. Extremely pleased with the price point.

  20. Great replacement for fan heater

    Posted by Mike Allen on 4th May 2016

    We have a small bedroom which had a fan wall heater. it was noisy and made sleeping difficult. We replaced it with an Envi heater that was very easy to install and makes no noise. Finally a good nights sleep.
