    The thermostat is useful in controlling the heating unit especially in the cabin to assist in keeping the water pipes from freezing. Not occupied all the time.

    Great addition to our heaters

    I am glad we decided to get two thermometers for our two heaters. Just set the program and done. Works great.

    Yes, you need this with your heater

    I wish I had ordered one with each heater. I will be getting another. It is great!

    Set it & forget it

    Product functions as advertised. We are using the product in conjunction with the wall heater. After 3 weeks and some minor temp & timing adjustments I don't even think about it any more.

    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.

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!
