    Great Thermostat for a Great Price

    I did a little research before buying these Tstats and found that for the amount of options, design, and ease of installation, they are well worth their price. Installation was very easy and the overall look after installation is very nice and professional. Would buy them again in a heart beat.

    Easy to install and works flawlessly

    I've had four of these installed in my home for about five years now. They control four separate zones, all using envi heaters. I've been really impressed with how simple they were to install and how reliably they've functioned. I especially like how they're not just on or off, but regulate themselves according to the amount of energy needed to heat our home. They offer plenty of programming options and are easy to override when needed. If you have several eHeat products that you need to control in your home, I highly recommend these.

    Great product, Great price

    This Thermostat works just as i wanted. Easy to hook-up with supplied directions. I hooked it to my Envi Heaters, have it programmed to start warming my bathroom and living room 2 hrs before i get up and i have it stop when we usually go to bed. This is the same as the honeywell that you buy at home depot, just cost less. Other than the printed name on the unit they are the same. 2 flaps on the sides keep all the buttons hidden (and man there are a lot of buttons) so the unit looks sleek and modern. Highly recommend the product.

    The Best

    This product works very well- just as they described it. I appreciate it having the backlit screen so I don't need a flashlight when I want to make adjustments. Looks great on the wall with the controls hidden behind the easy to open doors. Luv it - And would definitely recommend it.

    Quality Product

    Not cheap, but good value. Quiet, solid, great display, good instructions and feature set. I'd buy this product and this brand again.

    Awesome Thermostat

    You cannot appreciate the engineering and thought that went into this product until you begin to use it. It's almost as if the designers were intent on using it in their own homes when they were done. Absolutely great and solid design. I'd give it 7 stars if I could. Has features they don't even list. Easy and intuitive to program. Has supercap backup which is like a battery, but isn't. Easy to mount and service. Great display. Modern appearance. Extremely quiet. I now have three.

    Great deal!

    I am using this thermostat for radiant floor heat. It's a great deal, same or better than some that are twice the price. I love the fact that you can program each day differently to accommodate different schedule through the week. It is intuitive to program, has a vacation setting, lit display and looks great. This same thermostat was sold by SunTouch 3 years ago under the SunTouch name, for more than double the cost. Now SunTouch uses a different thermostat that only allows Mon-Fri and Sat/Sun settings.

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!
