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?

  • Economical - low wattage technology (only 475watts). Costs as little as 4 cents an hour to run.
  • 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 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.
  • Hardwired Approved - Hardwired models are certified and approved for permanent electrical installation under UL Safety Listing 2021. The Envi heater finally answers the need for a legal and safe, hardwired electric panel heater. (Models HW3012T, HW3012N, HW3022T and HW3012N)

  1. Works great

    Posted by todd_schrock@hotmail.com on 23rd Feb 2020

    My 2nd one as my front room is 400+sqft and full of windows. Product works great, still waiting to see how it translates on the heating bill

  2. Great Price

    Posted by Kevin Arthur Gilbert on 20th Feb 2020

    This is the 2 one I bought. It works great and keeps the rm very warms with the air flow.

  3. Perfect for my tiny house

    Posted by Lisa Marino on 19th Feb 2020

    Right now I live fulltime in a fifth wheeler that's 28 feet long. This has helped my propane heater by keeping it from having to run as often, hence, saving propane. It works great as a stand-alone heater if it just a little chilly out & you don't want to turn on the main heater.
    I definitely recommend this, it was worth the $150 I spent for it. Once I convert my school bus, this will be moved over and hooked into the solar.

  4. Quiet and Effective

    Posted by mikesilva61@gmail.com on 19th Feb 2020

    I was a little leery on the heat output of this slim wall heater. I was pleasantly surprised at the output of heat, how thin it was as well as how quiet. I sleep lightly so that ting metal makes as it cools (floor standing radiant heaters) will wake me. I highly recommend these heaters for homes that do not have any type of heating (me!).

  5. Fast easy install

    Posted by Ben on 16th Feb 2020

    These little plug in heaters are awesome! I have installed in our mobile home rentals to help offset the high cost of running propane furnace. It is nice to know tenants aren't running dangerous high amperage heaters. I like how they can't be knocked over and it would be hard to set blanket or anything flammable on top.

  6. Quite satisfied.

    Posted by wlove@uwsp.edu on 16th Feb 2020

    Very satisfactory The one change I would make would be to angle exit vanes slightly to direct heat into the room and away from the wall.

  7. Awesome heaters

    Posted by Debbie S on 16th Feb 2020

    I had purchased 4 about 4 1/2 years ago. One of them stopped working 2 months ago so I switched to the one I had left and reordered 2 more. I like to have them in case the older ones stop working. I’m a satisfied customer.

  8. Great Heater

    Posted by magiciansj@gmail.com on 15th Feb 2020

    I got this for my bathroom and dressing area. It does a great job. Heats quickly and not too hot for placement and don't need to run it long. It really works for me.

  9. Safest efficient and best looking product to add heat to a troubled space

    Posted by Abe on 13th Feb 2020

    This is my go to economical solution for spaces that need more heat. The install process is great and the fact that this unit is not super hot to the touch gives me that sense of comfort when installing in children's beddroom's. This unit is silent and has no moving parts. The tilt shut off safety is an amazing feature.

  10. Great heater!

    Posted by Martha W on 13th Feb 2020

    We have been completely satisfied with our eheater. It was purchased for my moms tv room in our home. She is always cold and we can’t turn up the heat in the whole house for her.
    We were a little concerned with how warm the wall above it gets but we just turned down the thermostat a bit and it was better.
    It keeps her nice and warm. Thanks!

  11. Small, quiet, attractive and hot!

    Posted by gggandholly@gmail.com on 12th Feb 2020

    This heater is amazing. It took a day to heat up my bedroom and than it maintained the heat.
    It's hard to believe it can do this without a fan.
    Best for rooms smaller than 10' x 15' in cold areas. Great in our bathroom.

  12. Great heater and easy to install

    Posted by George J on 12th Feb 2020

    I ordered two of your heaters. One of them had a switch problem and would not work. I contacted you support people and they were excellent. Now I h as be two heaters installed and am very satisfied. It is a pleasure dealing with an American company and purchasing American made.

  13. Hot done Nicely!

    Posted by Aldo on 12th Feb 2020

    This is a great product. I can't imagine hesitating to purchase if it fits your need and space.

  14. just the right amount of heat

    Posted by lawrence1954@sbcglobal.net on 12th Feb 2020

    the heater was perfect for what I wanted. The cost was great and it was easy to install. It supplies the right amount of heat to make the room comfortable. its the best heater around. Thanks for making it,

  15. So far, so good

    Posted by Joe Austin on 12th Feb 2020

    We are using this product to help heat one of examination rooms. The original building design caused this room to hover between 64 - 65 degrees. With this unit, the room is now between 70 - 71. Our patients and the doctor are much more comfortable, and at a reasonable price.

  16. Low power consumption

    Posted by michael hartz on 11th Feb 2020

    Seems to work pretty well considering the price and low power use.

  17. Heater / Company Review

    Posted by Ron on 10th Feb 2020

    I purchased this wall heater and for approximately 10 days the tracking stated that it was in process but not shipped. Unable to get response. However, this may have been attributed to the holidays and they were very responsive when they did respond and bent over backward to make things right. I was impressed with their wanting to make my experience a positive one.

    I am very pleased with the heater. We purchased it to take the chill out of our mudroom, that is located on backside of garage, has exterior wall on opposite side, is on a slab and has 10 foot ceiling. We live in the Midwest and have cold winters. The heater has performed as published and we have not had the thermostat setting on the unit higher than its lowest setting. It keeps the 20 x 10 x 10 room comfortable. It was extremely easy to install and the published safety features are accurate.

    I am purchasing another for our basement to get ahead of next winter season. Our basement gets cooler when we run our fireplace and the heat does not turn on very often. Tested the unit in our basement and it did a good job of keeping it comfortable.

    Very happy with the heater and company .

  18. Excellent Heater!

    Posted by Teresa Evanosky on 7th Feb 2020

    Excellent heaters for the money. Easy to install and look great. The bedrooms I am using them in do not have heat and kept the occupants toasty warm on a very cold (16°) night. I highly recommend them!

  19. I would and do recommend it.

    Posted by Maria C on 6th Feb 2020

    Since I am in Florida, I can only say that it is
    quite enough to make my bedroom comfortable so the
    rest of the house need not be heated. Sorry I can
    not help you better.

  20. Best Heater

    Posted by Loretta Mazzola on 6th Feb 2020

    I purchased my first heater 10 years ago when we moved into our house. There was electric heat in 2 of the 3 bedrooms and no heat in one of the bathrooms. We put the first one in the master bathroom. We keep it on low during the winter and off in the summer. It works great and we are able to regulate the heat. We purchased the second one for one of the extra bedrooms. Again, we leave it on low all winter and when we are going to use the bedroom we turn it up a little. We just purchased another one for our second bathroom. There is some heat in there, but it is cold when the heat is down. I love it! Keep it at a steady heat and always nice anc cozy. I always recommend these heaters to family and friends. By the way, they all look great also. We pained two of them the same color as the walls they are on, and the last one blends great with my white washed shiplap wall in the bathroom.
