    No thermostat is extremely easy to use and brings the wall heater a step up. Definitely recommend it.

    If you are considering buying an eheat wall heater with the plug in cord, getting the PT300 thermostat I highly recommend. It adds to the efficiency in the way the heater works.

    Envy Plug-In wall heater with plug-in thermostat

    I purchase the envy wall plug - in heater along with the plug-in thermostat. The two together offer a perfect no-touch heat solution. The HVAC system failed that heated the apartment above my barn. I installed an envy heater in each room instead of replacing the very expense HVAC system. The renter couldn't be happier.

    PT300 Plug-in Thermostat

    This thermostat works extremely well. We have 4 Envi heaters and all of them operate on these thermostats. As a result they accurately maintain the desired temperatures for the spaces they're in. I was never able to satisfactorily regulate the temperature with the thermostat built into the heaters but the plug-in does the trick. Perfect solution.

    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.

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!
