This unit is very safe to have around, even if you can not be around it 100% of the time to make sure it does not get knocked over.

The surface stays cool. The unit can be installed out of the way, has overheat protection, and will turn off if not mounted correctly.

How To Install your Envi Heater

We mentioned earlier that installing your Envi HH3012T Electric Panel Heater is simple.

The following are the steps that you can take to get it set up and running.

  1. Use the wall mounting template to determine where your unit will fit on the wall.
  2. Use a level to level the template on the wall
  3. Mark the holes in the template where the wall anchors and mounts are.
  4. Remove the template and then screw the wall anchor into the wall using the mounts and screws.
  5. Place the heater on the mounts; they slide into the back of the heater easily. It will “click” when in the right place. Make sure the unit is flush with the wall.
  6. Turn it on!

Keep in mind the unit will not work if installed incorrectly.

If it does not turn on, be sure that it is flat against the wall and is straight.

As a quick tip, ensure that the power cord will reach an outlet before you complete the entire setup.

You will also want to keep the heater away from windows; running it while a window is open is problematic, and it can cause issues if your curtains make contact with it.


In case the Envi HH3012T Electric Panel Heater does not suit you, we made sure to find a few alternatives that might.
