Product Description


The HH3012T is a direct replacement to the HH1012T model. The Envi™ Wall-mounted Electric Panel Heater is one of the most efficient, stylish, and innovative space heaters ever developed. After 7 years we have finally refreshed the Envi Heater with a more stylish look. The HH3012T Envi Heater is a 120volt plug-in whole room heater and has a built in thermostat.

  • Convenient Cordset storage inside heater to tuck away untidy power cord. (only Plug-in models)
  • Hardwired models also available, approved for commercial installation.  (HW3012T/HW3022T - with built in thermostat and HW3012N/HW3022N - without thermostat)

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. Perfect for the beach house

    Posted by Mike on 2nd Apr 2021

    We have a 5 bedroom beach house in SIC , NJ. These houses were designed for the summer months. We have 2 bedrooms on the ground floor with vents on the ceiling which are fine in the summer because cold air drops but in the winter they are 15 degrees colder than the upstairs because heat rises. I put 1 heater in each bedroom and they are sufficient to warm both bedrooms , the hall and the bathroom. They are also safe for the grandchildren since they are cool to the touch. 2 thumbs up. We can now have guests in the winter without worrying.

  2. A very good product

    Posted by Ron on 2nd Apr 2021

    This is the third heater we've bought in the last several years. We've only had one fail and it was several years old. We are very pleased with your heaters.

  3. Love the heat.

    Posted by Barbara Powelson on 2nd Apr 2021

    Easily installed on an inside wall. Makes my sewing room the perfect temp.

  4. Excellent device

    Posted by Jane Crawford on 28th Mar 2021

    We got this for our child room to help in the cold winters. It has done a great job and is very safe!

    I was negligent in looking at the size before I ordered so that surprised me a little. It works though. We put it on one of her bedroom walls.

  5. Awesome space heater

    Posted by Dave on 26th Mar 2021

    This heater looks so clean mounted on the wall. Easy to install. Gives out plenty of heat for a medium sized room and no noise. You can look at it and tell it’s a quality built item. The heater uses very little energy to operate. My only issue is the thermostat knob is a little had to get ahold of because of my fat fingers. Love it and highly recommend it.

  6. Great Product!

    Posted by Jim Rennes on 26th Mar 2021

    Needed some additional heat for a bedroom which is at the end of a air duct run and runs cooler than the other bedrooms. Saw the product advertisement in a magazine and decided to order one. Easy to install and works as advertised. Provided the bedroom heat we were looking for and most of all is safe for the toddler who sleeps in the bedroom. Space saving design is great and we enjoy being able to adjust the thermostat to provide the room temperature we would like. Product well built. Jim R

  7. Love this heater

    Posted by Cindy Green on 25th Mar 2021

    We bought this heater on the recommendation of my cousin. The process of ordering was easy and shipment was fast. My husband installed it in our bathroom and I love how it attaches to the wall and is not very bulky. The heater works fabulous and I am ordering another one for my family room.

  8. Excellent supplement for my bathroom

    Posted by Sid on 25th Mar 2021

    This is a good product for additional heat in my bathroom, at night I have the heat turned down . This heater keeps the bathroom cozy and is totally quiet. I am very happy with this product.

  9. Coldest to coziest room in the house

    Posted by Josh J, Newton, MA on 24th Mar 2021

    My daughter's bedroom is over a garage and has three sides of exposure, and was always colder than the rest of the house. We remembered loving our Envi Heat in our old house and put the new generation Envi up on my daughter's wall. Now she is cozy all the time and has even had her skin improve.

  10. Great unit for the price

    Posted by William W Jones on 24th Mar 2021

    I have three of these heaters and all work great and better than my expectations. I will definitely recommend to my clients who are wanting supplemental heat.

  11. Love my envi wall heater!!

    Posted by Cheryl M on 24th Mar 2021

    This is the second envi heater I've purchased. I've had the first one for many years, and it still works great. I love that the box is also a mounting template, clever idea! I love that it doesn't make any noise, or blow air around. I am very space challenged, and this is such a great solution for cold rooms! Thanks for a great product, it is so safe, and efficient!! (I do think that my new one needs to be set a little higher than my old one to maintain the same room temp.). I feel safe leaving this on all of the time, and highly recommend this heater for any room!!

  12. Happy Family

    Posted by Kathy on 24th Mar 2021

    I am very happy with my wall heater it doesn't take up space like some other heaters and is easy to control

  13. Best wall mounted heater!!!

    Posted by Miguel Lazcano on 24th Mar 2021

    This heater is the best heater money can buy when it comes to performance and funtionality. Simply the best wall mounted heater you can buy for a room.

  14. This one is a keeper !!!

    Posted by Charlie Nardin on 24th Mar 2021

    I have a 1200 sq ft cabin in the mountains and when night time temps fall into to 20’s inside the cabin will get down into to 30’s. Not any more ! Last week with night time temps at freezing and a little below I arrived to an inside temp was 54º.
    Does exactly what I needed to do. The 20º plus makes heating the cabin quick and easy and no more winterizing. I now have three of them.

  15. Great heater!

    Posted by Kelly Pawlik on 23rd Mar 2021

    Ordered this heater for the one room in our basement that never seems to stay warm. This heater was a perfect solution and the 120 sf room is now very comfortable. Shipping was fast and installation was quite simple. Definitely recommend this product!

  16. Does a great job keeping things warmer

    Posted by Michelle A. on 22nd Mar 2021

    I recently installed this in our basement TV area, as it's always super cold in there. Was pretty easy to get wall mounted with minimal tools. The space isn't as enclosed as what's advised (it's open to a stairwell), and is a bit larger too, but this unit is making the area much warmer and cozier than it was, and I love that it's silent and safe while doing the job. The wall above it is quite warm, but nothing dangerous, just as promised.
    Be warned: it will really stink when first run, but most new heaters do!

  17. Good price

    Posted by Mark H. on 21st Mar 2021

    Nice heater/good price

  18. Easy to install, attractive.

    Posted by Ross C on 21st Mar 2021

    These come with excellent instructions, are easy to install, are attractive when mounted.
    One great feature is that they are not hot to the touch, so safe for where there are children.
    Add backup heat in a room that needs that extra boost.
    And are made in the USA.

  19. Should have purchased one years ago

    Posted by Sarah on 20th Mar 2021

    It’s quiet and efficient and he eats my 300 square-foot office, It’s now comfortable even on the coldest of mornings

  20. Quietly Heats

    Posted by Randy on 20th Mar 2021

    We use the 110 plug in unit in our cabin back kitchen. Heats the the space well. Nice and compact—very unabtrusive.
