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!

  • 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

  1. All that I hoped for.

    Posted by Mitch on 26th Dec 2019

    I installed one in a 150sqf. room and it is such even heat. Looks great and we gained back the space the old portable heater was taking up.

  2. Eheat, room heater

    Posted by Ed on 20th Dec 2019

    I purchased this to supplement the HVAC heat for our front porch where my wife has her desk working from home. We've had it on since I installed it and we are very pleased with it. It takes the edge off in the room. It was very easy to install.

  3. Good product

    Posted by jrs on 15th Dec 2019

    Easy to install, easy to operate, works as advertised.

  4. Great looking heater

    Posted by Mark lawrence on 6th Dec 2019

    It took a while to get , but, was worth the wait. When I first opened the box I was impressed, part of the packaging was a template to mark the mounting holes. Wiring and installation couldn’t have been simpler. I turned it on and was very happy with the silence and the heat output. I will buy again, great product!

  5. Premium Product

    Posted by Gary on 5th Dec 2019

    We have just installed your Envi wall mounted room heater and I must tell you it has exceeded our expectations. we purchased the timer as well and it was easy to install with no difficulty. Thank you for a American made top quality product!

  6. Great heater

    Posted by Melanie Ranney on 20th Nov 2019

    A wonderful heater
    Efficient, attractive, fits a small space, safe
    Now have two ENVIs
    May be be back for another!
    Thank you!

  7. Heater made a huge difference

    Posted by Shawn on 18th Nov 2019

    We got the ENVI heater to add supplemental heat to our master bath. The heater is quiet, and works like a charm. Unobtrusive as well. we couldn't be happier.

  8. Great Heater for solar house

    Posted by Mark Humphreys on 17th Nov 2019

    This heater was perfect for our energy efficient home. Our primary heating system is with mini-split heat pumps. When we close the office door the room becomes cool, this heater worked perfect to keep the room warm. Living in the Northeast it gets pretty cool. Have had the heater for about about a month. Time will tell if we see any significant increase in our electricity bill. We produce about 75% of our total electric need with a solar array system

  9. Elegant and Better Solution than Oil Filled Heater

    Posted by J. Emerson on 7th Jun 2019

    I installed the 120 hardwired heater on my bathroom wall. I had an available wire in exactly the right place, so the job--cutting a junction box hole in the sheetrock, cutting a wire, and splicing the Envi wire--could not have been easier. The Envi replaced an oil filled radiant heater that took up a lot of floor space and collected a lot of dust and dirt in its complex and hard to access radiator design. That heater did the job of heating, but the Envi, at a third the wattage and a third the size, heats faster and cheaper. That it is also beautifully designed and easy to intregrate unobtrusively into the overall bathroom design makes the heater just about perfect.

  10. Easy to install, quiet, clean heat.

    Posted by Terry on 9th May 2019

    We ordered 6 units to use as the sole heating source for a newly finished, 3 bedroom garage attic apartment. Installed one in a sheetrocked 11x13 bedroom on a cool evening to test. Quick, easy installation, as advertised. Remarkable amount of heat for 475 watts of power. Over 3 hours it did raise the room temp several degrees over the unheated area, but not sure how it will fare in sub-zero temps. Pending attic insulation and wall and trim finish will undoubtedly help, but won't know how much until next fall. Still think it's a good value for the price. (Dropped rating one star because winter temp performance cannot yet be confirmed)

  11. My envi heater

    Posted by Lora Atcher on 15th Mar 2019

    A great product! So glad I made this choice. Heats the room very nicely. I will definitely buy another one for other rooms.

  12. Very happy with this heater

    Posted by Kim on 17th Feb 2019

    We needed two new heaters, so I bought this one and a competing surface mount passive (fan-free) brand. The Envi heater was much nicer in the end.

    Though both work equally well, the Envi heater looks a thousand times better. The other heater looks very office-industrial and not in a hip way. That brand sticks way out from the wall too, leaving wires in a weird way. And the temp controls are hard to use on that other brand.

    The Envi one was sleek, goes against the wall like it should, and the temperature controls are straightforward and easy to use. We'll use more of these in the future in our new house.

  13. Great Heater

    Posted by Dan on 17th Jan 2019

    This is the 3rd one we have bought. They are great for small spaces such as bathrooms. Very easy to install with the enclosed template.

  14. I love this heater and will buy more

    Posted by Anna on 10th Dec 2018

    I've had my heater for about 2 years now (previous generation). I love it because I could mount it relatively close to the bed and it is safe. I could close the vents in my bedroom because I dislike force air heat (throughout my house). The air is clean and not dry, plus no fluctuation from too chilly to too hot while I sleep. It is very energy efficient, cool to the touch and is perfect for an appx. 130 sf. bedroom. And I live in Michigan where temperatures can go as low as -30 degrees.

  15. Hot Little Heater

    Posted by chforslund@yahoo.com on 6th Dec 2018

    This heater was very easy to install, even for us non-mechanical engineers. It's very attractive on the wall and does a good job supplementing heat from an aging electrical forced-air furnace. A good addition to the installation kit would be a small capsule-type level to make sure it's level on the wall (like picture frame sellers use). The thermostat is great. And the unit is totally silent.

  16. Warm and safe for pennies

    Posted by Judy D from LaFayette, GA on 6th Dec 2018

    This is actually the second heater we have purchased. I have one in my laundry room that before had no heat at all. We have had that one for several years with no problems at all. They are very easy to install and USA made. The one we just bought was for my mother in-law for her bathroom. It's easy to use and safe which were our main concerns for her and she loves it. We highly recommend.

  17. Quiet, efficient heater

    Posted by Lia Middelhoven on 6th Dec 2018

    We love this heater! Very efficient. Totally warms our bedroom. Love that there is no fan running. Just quiet, warm heat. Recommend highly.

  18. Best panel heater on the market

    Posted by Bill L on 6th Dec 2018

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

  19. Great Heater

    Posted by Rich M on 6th Dec 2018

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

  20. Impressive

    Posted by Charlie Mishk on 6th Dec 2018

    Very impressive unit. Sceptical at first but i wanted to try something different. Tried many things in the past to warm up this room that's far from the tstat and in the back of the house. Very easy to set up and use. Installed this and monitored the room for several days to find the rite setting. This unit works so well that im'e going to get another for another room then possible replace a 220 volt unit in my washroom.
