    I have 3 thermostats and Envi heaters in use in the lower level of our house... the thermostats work really well in keeping the rooms comfortable without overworking the heaters... a great assist to the main gas furnace

    Envi 120v Plug-in Panel Wall Heater

    This is the third wall heater that we have purchased. We planned on using it in a downstairs bedroom but our daughter was interested in getting one for the front entrance to her small home. We decided to gift this one to her and she is extremely pleased with how it warms up her unheated entryway. We placed heaters in our unheated office, master bathroom and also put our original heater in the unheated sunroom where our cat sleeps. They are a great addition to our heating system that is partially fueled by new solar panels. This month's energy bill was slightly over $14 for a 5,000 sq. ft house.

    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.

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!
