    I now have 10 heaters with attached thermostats. I purchased the last three to ensure all heaters would be available in case of the loss of our furnace. I have had the other 7 thermostats for several years and they have been very reliable and have worked with no problems. I appr$zite the reliabilti6 as these can be very critical to the home.

    A great plug in controllable thermostat

    Just programmed and installed this well made thermostat tonight. A great way to control the temperature for the second floor of our mountain house. Installed in conjunction with the plug in Envi heater so I can keep some heat on upstairs without using the baseboard heater. I will probably be ordering another thermostat soon.

    A Best Buy

    I bought my first Plug in unit as a local area heater in the Bar area of my basement for use when I can't be bothered to light the wood burning Stove. I found it very easy to install and it is adjacent to an outlet where I could hide the wire behind an existing piece of wood trim.It provides sufficient Heat for what I wanted. I have now bought a second unit to install in a Bathroom I am restoring. It will be mounted on the wall beneath a Towel Bar to dry and heat the Towel. I have yet to instal it but I am sure it will be exactly what I need. I think they are ideal to use as a low powered space heater. Out of the way and off the floor.

    Works great for older parent

    My father died earlier in the year and my mother came to live with us. She has her own bedroom and like most older people they like it warmer or should I say hotter. I keep my house at a normal temp and the Envi heater supplements the heat in her bedroom. It was easy to install and regulates the temperature with the plug in thermostat . It is quiet and does what I wanted with no fans, infrared coils or hot to the touch space heaters. The cold weather has not even arrived and I am really happy with the unit.

How It Works

The Envi Heater’s innovative dual-stack design was born out of years of research and development. The results revealed that the most effective way to heat a room with the least amount of energy is by heating the air in a room using 100% natural convection.

The Envi Heater’s inner chambers feature simulated “stacks” of varying height, which boost airflow through the unit to maximize heat transfer. The end result of this technology is enhanced airflow and safe air temperature, all without the use of a fan!
