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!

Panel Heater is to Install Yourself
Worried about paying to get a contractor to install your new Envi wall heater? Think again. Jason Cameron explains how the Envi wall heater is designed to be installed and set up at home by yourself in just 10 minutes or less.
Makes the heater super effective
I hardwired one of these into my RV and it is fantastic because the thermostat allows the heater to just barely come on. It also remembers what the temperature was the last time you were plugged in at an RV site or with the generator.
I have installed this non programmable thermostat in each living space; paired with a hardwired Envy heater. It creates zone heating. The heat setting is maintained making the room temperature consistent. No high and low spikes, just even heat. The operation range, low and high set points, current temperature display, backlighting and the little heat wave display make this non programmable thermostat an easy choice over the basic on/off thermostat for just a few more dollars.
It is hard to find a thermostat that will work on old school wiring this one will, it does work well when installed it was questionable when I first hooked it up it was glitchy, before I had it installed on the wall but two weeks now and no complaints for the mo yes you can’t go wrong
Envi High-Efficiency Whole Room Hardwired Electric Panel Heater - No Thermostat (HW1012N) - I mistakenly thought the No Thermostat on the heater meant no wired in thermostat but actually it refers to the dial at the top right of the heater that is also called a thermostat. The users guide and pictures on the box and online show the Heater with the dial and I thought I was purchasing what I saw. The 220 heaters are great but clarification on "Thermostat" - external thermostat or dial thermostat on model would be helpful.
Replaced a mechanical dial type for my forced fan electric wall heater in the bathroom. I really like being able to see the ambient temperature of the room. Was easy to wire. Absolutely silent operation.
