The Technology

The dual-stack convection technology featured in the Envi was born out of years of research and development to find a solution to effectively and safely heat a room using the smallest possible, amount of electrical heating energy.

Dozens of heating methods were evaluated to fine tune the Envi heater, but eventually the answer was found in a naturally occurring phenomena called the "stack effect". This provided the basis for and eventually we won a patent for the final Envi heater design.  Natural convection, fanless heating is enhanced by simulating multiple pathways, or “stacks,” inside the Envi heater.  This technology boosts the flow of cool air from the floor of a room, into the unit, and maximizes heat transfer out the top of the heater.  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 a house or office - or any room or space for that matter!

What are the Benefits?

  • Slim - Just 2 inches thin
  • Stylish – Beautiful flowing curves compliment any room interior
  • Healthy - Fanless, non-forced air design that doesn't blow dust or allergens into the air and around the room.
  • Sleep friendly - Silent and auto dimming on/off power light in dark rooms, is helpful for light sleepers.
  • 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.

  1. No more cold spots in my house

    Posted by Mark on 13th Jan 2021

    I bought this unit to heat the den of our colonial style house. The room is on a slab that settled closing off the ductwork to the room. We installed the heater with a line voltage stat and it works very well to take the chill out of that room

  2. Best purchase

    Posted by Catherine S. on 27th Dec 2020

    I rarely leave reviews of products, but I am so thrilled with this panel heater I have to! It is as nice as the pictures make it look - modern, sleek, SILENT, cool to the touch, and no hot air blowing - just emanating warmth. My freezing bathroom has become the most pleasant space due to this heater - it is a ridiculously good investment and solution for zone heating.

  3. 4 purchase and 9th referral

    Posted by David Cash on 25th Dec 2020

    Love these heaters- prompt delivery, ready to install and very effective. Just helped to install four in a friend’s cabin. Done quick and she’s happy. Love you guys!

  4. So far, so good.

    Posted by Joe on 24th Dec 2020

    Works as advertised. Only a bit shy as I had to return a different unit for repair in less than one year. We'll see how this one performs and holds up in the long term. Merry Christmas to all.

  5. wall heater review

    Posted by Luciano C. on 21st Dec 2020

    Have only had it for a week...seems to be working ok so far - the wall surface above the heater seems to get warm though

  6. Great heater!

    Posted by Doug on 9th Dec 2020

    This is a great little heater. We installed ours in a new laundry room and it is perfect! Didn’t even notice an increase in the electric bill.

  7. It's beautiful and it works!

    Posted by Diane on 3rd Dec 2020

    It was received promptly. We just installed it and not only is the design attractive but it also works very well. There were many warnings about the smell that the unit initially emits during the first day. There was indeed a smell but it was quite bearable and was gone within 24 hours.
    Overall,I am extremely pleased with both the merchant, their high quality service, quick delivery, usability of their website and with their really attractive product.

  8. Everything it was advertised to be!!

    Posted by Dave Fontinelli on 3rd Dec 2020

    It really is fantastic. It sleek ,quiet, and really heats quickly

  9. Compact, SILENT WALL HEAT.!

    Posted by Paul Silva on 3rd Dec 2020

    THIS IS a GREAT addition to our Bathing and Showering Dailies.!
    I am not eloquent enough to put in words how much I regret NOT Buying this sooner. Although it is the beginning of winter in The CA. Sierras. I chose a good time for it.
    Also, it cuts down on the mirrors fogging up.!

  10. Warms up the bathroom

    Posted by Bob Goetze on 13th Nov 2020

    Available flat wall space was limited in our master bath but my wife always complained that it was chilly when showering. There was a narrow angled wall along side the shower roll-in entry. That wall did have electricity for the shower lights, fan and infra-red type lights. It also had a blank-face GFCI from a jacuzzi tub removed 14 years ago. On the down side there was an HVAC louver on the lower 12" of the wall above the molding so if I mounted the Envi panel it would be higher than recommended. But that's where it is. It works great. I'm sure its reheating some of the HVAC conditioned air but it doesn't seem to matter. I never have it higher than the third dot on the thermostatic control and it keeps the bathroom nice and toasty warm. I hard wired it down stream from the blank-face GFCI, another plus. I used a double duplex box for a little extra room for the wires and wire nuts.

  11. Purchased twice

    Posted by Columbo on 13th Nov 2020

    Purchased two had them 1 year they preform perfectly . I’ve repurchased four more to heat small 550sft four room house. They preform better than furnace system

  12. great heater and good customer support!

    Posted by Shelly on 2nd Nov 2020

    We bought this heater for my daughters bedroom to replace the unsafe baby high and very hot electric heaters that were in it before. i love that it comes in a plug in or wire in option. i wired it in so that the baby wouldn't have a cord to pull on. Unfortunately the mounting hardware was missing but when i called they answered right away and sent me the hardware in just 3 days. Of course i didn't realize the mounting hardware was missing until I had already hard wired it in. So my hubby used some washers on screws to mount it temporarily. Once we had the proper mounting hardware we locked it into place. this is my dream heater when it comes to safety!

  13. Works

    Posted by Laura M Davis on 30th Oct 2020

    So far, so good. Used it in a slightly larger space than it's advertised for and pretty happy with the results. It looks great and was super easy to install. Very east to use. All in all, very happy.

  14. Very steady, consistent heat, installation challenging for uneven walls

    Posted by Brad McCarthy on 15th Oct 2020

    Heat: the heat is really consistent and is able to maintain a temp in our bathroom that has two external walls (brick house, ~80 sq ft, Wisconsin fall temps).

    Installation: overall, the installation was really easy and straightforward. We have textured walls that are very slightly uneven and it was pretty challenging to get the clips in. Ended up needing to use washers to move the clips away from the wall.

  15. Good so far, looking for more

    Posted by Thom Tree Farmer on 13th Oct 2020

    2 years ago we bought this heater for a new addition. It has performed very well. Based on that success, we bought 13 more for a new house we are building. The ability to 'zone' each room is crucial for us. There are areas of the house that we will lower the heat at times. These rooms can be closed off. We can control the cost of heating with this method of operations.

  16. Great product

    Posted by David - Seattle, WA on 30th Sep 2020

    I'm not sure which order this review is pertaining to. I've ordered 4 of these heaters in 3 separate orders. Obviously I keep coming back for more. Highly recommended product.
    Only negative I have to say is the last one I ordered arrived DOA. But that's not a reflection of the quality of the product, just an unfortunate thing that happened.
    Samantha helped me with a return label and we're getting it taken care of. Great customer service!

  17. Efficient and effective

    Posted by Erik Zimmerman on 13th Sep 2020

    I installed my Envi heater yesterday, but I had a good experience buying one for our previous home's basement. This one we installed in our three-season porch. I'm optimistic I can get another month or two of use out of that space in both spring and fall. It seems to be working well so far!

  18. Need to wait for winter season for a trur test.

    Posted by LJW on 11th Sep 2020

    Works fine upon installation. Quiet performance. December will be the true test.

  19. Straighten out those cold spots

    Posted by ray on 10th Sep 2020

    During the time COVID-19 Shelter in place was going on I found that working in the dining room in the morning was rough. It was colder than the rest of the house. I installed your product by myself just two wall hangers and a grounded plug for the wall socket. It's a big improvement. I can walk into the room and feel comfortable enough to get to work.

  20. Very subtle and pleasant heat

    Posted by Michael on 27th Jun 2020

    For my purpose , namely heating up a small space ( bathroom) this is a perfect heater. Extremely quiet and efficient. In a few minutes the space reaches the ideal temperature. It’s subtle and barely noticeable.
