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

  1. Envi Heat solved my problem

    Posted by Roland on 14th Mar 2019

    Finally a great product! Solved my problem with cold rooms without needing to turn up the central heat.

  2. Good Product

    Posted by Unknown on 14th Mar 2019

    I bought this heater because the usual space heaters I've used consumed too much power (1500 watts), running up my electrical bill. I haven't tried the eheater enough yet to know whether its 400 watt consumption will have a meaningful effect, but I am happy with its heating ability. I use it in my workshop, and even though I set it a little higher than the instructions say (mine is at 20 inches from the floor, so I can stack lumber on the floor)it warmed the place well. I also really like the wall mounting, and the overall slim appearance.

  3. Excellent heater

    Posted by Melissa P on 11th Mar 2019

    We like the wall mounted heater very much. It was easy to install, works well, looks good and is very efficient .

  4. Works great in a bathroom

    Posted by Bob on 10th Mar 2019

    I bought this for an upstairs bathroom that never warms up with the heat on. It worked great heating up the bathroom before showers, in the morning, etc. It was an easy install with the mounting screws. Finish looks great and it seems well constructed, solid not flimsy. Quiet and cool to the touch. I can keep the thermostat on a low setting and it heats the bathroom up to 70-72 degrees. I would buy again. Made in the USA is a plus.

  5. Stylish, Cost effective and really does the job!

    Posted by Robert W. Meister on 8th Mar 2019

    The closet off our ensuite has been a topic of discussion for my wife and I for several years. It is on two outside walls and is mcuh too cold for my wife.
    While doing other renovations this year we looked around for a heater for the closet. Most units were for heating much larger spaces, needed direct wireing at 240 and cost too much to buy and to operate. This Envi unit is perfect. Thank You

  6. Nice

    Posted by Dennis on 8th Mar 2019

    Install could not have been any easier. Super quiet, and cool to the touch. Love that it's made in the U.S.A.

  7. Surprise! It works.

    Posted by Frank E on 7th Mar 2019

    I agree with the posts I've read, so I won't repeat them. I had a bedroom that ran four degrees cooler than rest of home. After running a couple days at partial highest temp setting, room temp is up five degrees. I'm happy. I would suggest positioning the knob of the thermostat up a little taller so the knob is easier to turn.

  8. Good little heater

    Posted by Gary Auger on 7th Mar 2019

    I am testing my new envi heater in an area thats far larger than the unit is designed for. From what i see thus far this will be a perfect source of heat for my bathroom at camp which is the reason i bought it. I am happy with my purchase and can see that this heater will be very handy for my needs.love that its so quiet too.

  9. Awesome heater

    Posted by Rick on 4th Mar 2019

    Easy to install once I saw the YouTube video describing what the locking bar is. Quiet, heats nicely, American made. Great product

  10. Easy to install, does the job.

    Posted by Steve on 4th Mar 2019

    Well packaged with easy to mount template included as part of the protective packing. Heater blends nicely into the room. Would be 5 stars if the thermostat had a temperature setting instead of just a dial.

  11. basement bedroom

    Posted by Ruth L on 4th Mar 2019

    Installs so easily and it's super quiet. Perfect for our downstairs bedroom. A great space saver.

  12. Comfortable quiet heat

    Posted by Terry R. on 4th Mar 2019

    very easy to install. took a few days for the room to get warm but now stays at a comfortable temperature

  13. Easy Install Good Results

    Posted by Bwall on 2nd Mar 2019

    Installed watching video on website and worked real time with the video. So easy. Turned on and room was noticeably warmer within a few hours. Silent as promised. Large room, so I may add another.

  14. Toasty bathroom.

    Posted by David A on 2nd Mar 2019

    We purchased the Envi plugin for our master bath. We live in Southern Colorado in the mountains and have large window in the bathroom. Even though our home is well insulated it would still be very cool in the room with our cold winter nights. After installing the Envi, which was very easy, we now have a “toasty warm bathroom even with our very cold nights. It was a perfect addition to the room!

  15. No more cold bathroom

    Posted by Loretta V on 1st Mar 2019

    We already had Envi heaters in 2 rooms in our 150 year old farmhouse. As our weather is quite variable they help to maintain a bearable temperature throughout the winter. Our bathroom had no heat at all and we finally rearranged it to allow for the addition of an Envi heater. It is wonderful!

    The staff at eheat has always been extremely cordial and helpful. Thanks!

  16. Perfect Solution

    Posted by Sharon C on 27th Feb 2019

    I live in a rainy area and since I put in Env Heaters, I have no more mold problems. The heaters are quiet easy to install and my electric bill cut in half for the winter.

  17. Great product just took longer to get then I anticipated.

    Posted by Susanne Marx on 25th Feb 2019

    This is my second order. Super easy to install and heats the place great, quite and efficient. They were on backorder but have caught up now.

  18. Great heater!

    Posted by Michelle W. on 25th Feb 2019

    I'm very happy with this heater. I love the design that makes wall mounting easy. And the heat production is perfect. Using 3 now! May get another!

  19. Excellent product

    Posted by Kenny N on 24th Feb 2019

    Quick and easy install. Works great in our tile bathrooms and in all our bedrooms. Definitely recommended to warm up different rooms that always seem to be a little cooler than the rest of the house

  20. Nice Heat - doesn't dry out the air!

    Posted by Unknown on 23rd Feb 2019
