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!

  • Healthy - Fanless, non-forced air design that doesn't blow dust or allergens into the air and around the room.

  • 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

  1. 4th one

    Posted by Frinda Maness on 15th Jan 2019

    This heater is just as good as I expected. It heats a medium size bedroom. We have had Envi heaters since 2012. I love the size and of course the efficiency of it.

  2. Satisfied customer

    Posted by Ralph Rumer on 15th Jan 2019

    I have purchased three of these heaters; one for a cottage bathroom in Pennsylvania, one for a small bathroom here in North Carolina and one for a larger bathroom here in North Carolina. They are used primarily to keep the bathrooms warm during the night (when home thermostats are turned down) or during daytime use when outdoor temperatures are very cold. They do the job wonderfully.

  3. Managing the temps

    Posted by Brian Onieal on 14th Jan 2019

    I received the product and installed them without any issues. The silent heating system keeps the rooms at a steady, comfortable temperature during this NJ Winter.

  4. Economical Heating

    Posted by Sharon on 13th Jan 2019

    We purchased one heater in 2018 and loved how warm it kept our lower level due to a doggie door that was poorly sealing. This year we bought two more, one more for a bedroom on the lower level and one for the upper level. Both units are working great! These are very economical to use, look nice and are easy to install.

  5. I love these heaters

    Posted by Linda Pearce on 12th Jan 2019

    I now have six of them. Two are hardwired and four are plug ins. They have literally replaced my high priced propane FAU. My bills have been reduced over 75%. Like I said. I love these heaters.

  6. Best product I've purchased in the last 5 years

    Posted by Ben A. DeLozier on 12th Jan 2019

    I bought one heater (with built-in thermostat) sometime in October of 2016. Reason for purchase was my ceiling heat (yes, old school) went out and it would be $200.00+ to have it repaired, again. Kids are all out of the house but my wife and I do have 3 small dogs and they could lick this heater without harm if they had a mind to, it's kid/pet friendly, so I know my grand-kids are safe too. My 1st purchase was a performance test in a cold back bedroom, and I easily installed my wall heater the day I received it. Up to now, it has more than solved my problem of a uncomfortably cool bed room. I turned it on in Oct (2016) and never turned it off, as I type this, it's still on and working the same as the day I turned it on. With the addition of this heater, always "on", my electric bill showed a marginal increase easily balanced against a now toasty back bed room. My wall heater looks classy, it's quiet, and compact. My only caution to future purchasers is that this is not a glow red fire breathing heater like may space heaters, it well suits a small room (my room is 10x14) and takes time to heat up and then maintains a comfortable warm space, in my case 70-72 F.. Since my initial test of my first wall heater, I have purchased 4 more of the same, and am well pleased. Have not felt this satisfied with a product as I am with my heaters, in a long, long time, Thank You.

  7. Great heater for sole heat source!

    Posted by Mark Varshock on 8th Jan 2019

    If I were building a new house I would put one in every room. There would be no need for any other heating sorce.

  8. Great product

    Posted by Aqua Bella Organics on 7th Jan 2019

    We have about 10 of this brand in use at our warehouse for our hot rooms. They run 24/7. Only had one break down after 2 years of use. Great product.

  9. These heaters work great!

    Posted by Ed Saidla on 2nd Jan 2019

    Just finished installing my third Envi heater. These heaters work great, no noise, efficient and cool to the touch. Perfect for areas that need extra heat.

  10. Very Good heater

    Posted by Scott on 2nd Jan 2019

    Put one of these in my tack room years ago and it works great. Bought another for the feed room in the barn and it takes the dampness out keeps it just right! Nothing freezes.

  11. Great Product...Great Customer Service

    Posted by Robert S. (Steve) Bell on 2nd Jan 2019

    So refreshing to find a great company with a great product that also has exemplary customer service. I now have installed 7 units, 4 220v hardwire and 3 110v plug ins. Very satisfied with how the units operate and especially like the cost savings on my electric bill.

  12. A Great Wall Heater That Really Does The Job!!!

    Posted by Ward on 2nd Jan 2019

    I've had two of the units for several weeks now and must say they are much nicer and warmer than my previous panels that I had installed, and I have yet to set them on maximum. The body remains cool to the touch which I like. The 3-year warranty is one of the best in the industry. Installation is a breeze, and I love the grounded wall plug and the push button on and off switch. There is just nothing to find wrong with this unit, not to mention they fact they are U.S. made. You must don't find that much anymore. Should I decide to get more units, this will be the one. I've been telling all my friends about it. Great Job Eheat!!!

  13. We love envi heaters!

    Posted by Jeke on 2nd Jan 2019

    These are great little heaters. We use them in many rooms. Easy to install, but be sure to read the instructions, as it can take a little work getting them set properly so that they turn on.

  14. Excellent heater

    Posted by Trudy on 2nd Jan 2019

    I installed my Envi heater in my bathroom last weekend, it took about half an hour - only because I read the manual first. It was dead easy. The only negative is that you start a screw at the bottom left and have to tighten it once the heater is mounted, using the provided allen key. This is virtually impossible to do and even laying on the floor I had a hard time and finally gave up. However, the heat is perfect and adjusts easily and it looks really nice, is low profile, and is safe. I did find the cord a little short, I needed 12" more so had to buy an extension cord (if the cord had been on the other side it would have reached LOL!) So all in all I highly recommend this heater.

  15. Great product

    Posted by Sherrilyn VanTassel on 2nd Jan 2019

    These heaters are convenient and efficient.

  16. Worth the wait!

    Posted by Ed Kmotorka on 2nd Jan 2019

    Repeat purchase, own 3 now; delivered and received as ordered, but was on back order for 3-4 weeks!

    Very happy with my repeat purchase; highly recommend these for an old historical house in CA!

  17. Life saving heat ????

    Posted by harrywolfgang2@hotmail.com on 2nd Jan 2019

    Great back up . Prevents pipes from freezing. Price excellent value. Looks smart. Easy to install. Everyone that seen them asks where did I get them.

  18. Quality Heater

    Posted by WoodDoc5171 on 2nd Jan 2019

    This is our third Envi heater, but our first one that’s 110v with its own thermostat. It’s working as well as the 220v versions we’ve had in place for more than 5 years. It provides supplemental heat in a coolish room and keeps it perfectly cozy. Great heater and great folks at e-heat.

  19. Great Heater

    Posted by william k on 2nd Jan 2019

    Great heater, worth every penny. quiet and provides even room heat. we're on our third heater with using the last one to heat a crawl space to keep the pipes from freezing. with having the crawl space insulated this heater kept the heat at 60 degrees when it was only 5 degrees outside. well worth the investment, thanks

  20. amazing

    Posted by TRACY NOISSEAU on 2nd Jan 2019

    I l ove the product, it matches my decor , its very safe, it pulls cold air from the floor and converts it to warm air . it is clean and so cost effective . this is the second one I bought . my first one was last year in march . I use 1 in my refinished attic for zoned heating when we are in the gym and the other gets used in our living room as it is a little drafty. I live in upstate NY and winters well they have their moments. its quite.This year when I ordered it was on back order and it took a few weeks to get and I was fine with that cause waiting for this is worth it .
