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.

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 475/500 watts). Costs as little as 4-5 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

  • 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. USA heater

    Posted by Rhonda on 20th Dec 2020

    We have owned 2 heaters one was old and went out ordered another put both in a 2 car garage and it keeps it 70 degrees. It has been cold where we live and still stays 70 degrees. The best part is it’s made in USA.

  2. heating a large family room

    Posted by Joan M on 20th Dec 2020

    Our split level house has always been difficult to heat because of the thermostat location. Our kitchen/family room was always chilly. This room measures 22' by 16' and the installation of two eheat panel wall heaters has been most effective. A nice constant background heat.

  3. Excellent product!

    Posted by Mary on 19th Dec 2020

    We are very pleased with the efficiency and high quality of this heater. It’s attractive simple design is very unobtrusive. We bought the eheat 120 v plug in version for our 10x10 porch which we recently had enclosed. We installed it ourselves and found the directions and videos to be very helpful. It is working wonderfully so far- so quiet and it heats the space to a cozy level even with outside temperatures are in the single digits!

  4. Good heat output

    Posted by Tony on 19th Dec 2020

    Bought one of these to warm a very cool bedroom. Worked so good that I bought two more. One for my daughter and one for my son. Only complaint I have is that they should put a sticker with the model snd serial number in the instruction book. Hard to register the unit unless you take it off the wall.

  5. Excellent heater

    Posted by Fran Shriver on 18th Dec 2020

    I did a lot of research and calculations before I chose this heater. I have a home with central heating, but my Mom moved in with us and needs it warmer than my middle aged female self can tolerate. So I needed something safe for an elder and that could be used to supplement rather than heat on its own. This looked like the best bet for my situation, though it was much more expensive than some other products.

    I'm here to tell you it was worth the money. It is well made, installs VERY easily, conserves floor space, and works great! Mom loves it, and I love a happy, comfortable Mom!

  6. Good Heater

    Posted by Patrick P on 18th Dec 2020

    Very well made unit. Works great.

  7. Satisfied customer

    Posted by Richard Brown on 18th Dec 2020

    Attractive looking heater and very easy to install. Follow the instructions this heater works perfectly and heats very nicely.

  8. Easy to install & works great

    Posted by George Rancourt on 17th Dec 2020

    We bought our first two in 2015. Our daughter took one to her new home. We just ordered 2 more. They work so well and make no sound. The box is also a template and it only takes 2 screws to hang on the wall. The cord has a storage area for (excess cord). It is safe for pets & little ones.

  9. Happy with eHeat product

    Posted by Jeffrey A. Lamphere on 17th Dec 2020

    I needed to add a small heater to a kitchen wall and bedroom that my 80 year old Mother-in-Law uses. I couldn't be more happy with the product design, packaging and ease in installation. A-plus!

    I'm only giving 4 stars because ideally, I wish the BTU output was a bit more. However erring on the safe side with little kids is a plus. Overall a great process.

  10. Outstanding Product

    Posted by Jonathan K. on 17th Dec 2020

    This heater performs exactly as advertised. My home office, which has two windows and two exterior walls, is the coldest room in the house. With your electric panel wall heater, it is now the warmest room in the house. It performs exactly as advertised - warm, efficient, absolutely silent, safe to touch and inexpensive to operate.

  11. Excellent quite heating option

    Posted by Brian F, Douglass, KS on 14th Dec 2020

    This heater works excellent to heat small spaces that lack central heating. I use this in bathroom in my garage that didn't have heat. It works very quietly and keeps the room well heated to a comfortable temperature. We especially like the thermostatic control on it. I would defently recommend this heater to friends and family. We will be installing a second heater in my daughter's room.

  12. As advertised.

    Posted by Artf on 12th Dec 2020

    We received this on a Sunday! Installed it in about 15 minuets. So so quiet. Cannot hear it at all. Great product. Would recommend it to anyone.

  13. Great heater, just needs...

    Posted by Phil V on 12th Dec 2020

    Love the eheat wall heater. Great concept, design and looks good to. I own 5 of them!
    The thermostat is barely ok. For the price range I would have paid more for a digital thermostat, AND the option to control it with modern technology, i.e. from my phone/ alexa . Nothing like it on the market that really maximizes heat output for the energy used!


    Posted by Lorry B. on 11th Dec 2020


  15. silent and energy efficient

    Posted by Marcel Schwarb on 10th Dec 2020

    I bought three of these heaters (two 220v and one 110v plug in) to heat a large studio space above our 3-car garage. I love the modern look and silent feature. They do a very adequate job of maintaining a desired temperature during the cold months in Washington State. Since we don't use this space full time, it would be more convenient to control the heat with an automatic thermostat rather than adjust each dial of each heater. I'll look into this, but not sure if additional wiring is required to interconnect them.

  16. replacement

    Posted by Don B. on 8th Dec 2020

    I purchased this heater ti replace another heat unit that quit working. I am not sure why because I did not use it often and did not leave it on for extended periods.

  17. Great looking heater to support existing heating system

    Posted by Greg on 7th Dec 2020

    This heater has been really carefully designed. Every detail from the packaging to the heater itself has been thought through. The instruction to install are crystal clear and the packaging turns into a handy template to locate where to install the mounting anchors on the wall. Took 2 minutes and didn't even have to pull a measure tape. 5 stars for the opening / install experience, and the quality of the design and fabrication. Now in terms of the performance - you get what a 500W heater can provide. In our case, it complement our main heating system but in no way could ever replace it entirely. I recommend this purchase as additional "comfort" piece.

  18. Excellent backup heater

    Posted by Mrinal Malhotra on 6th Dec 2020

    We purchased the envi heat product to provide backup to our heat pump. Simple to install and very very effective

  20. Great heater

    Posted by Joanne L. on 6th Dec 2020

    We had the original panel heaters from South Africa and liked those until we received the new Envi heater. Love that it has a thermostat. Have recommended them to several people.
