Ceramic Heat Emitter and Thermostats?

Hello… Do you think using a thermostat with CHE’s shorten the life of the CHE due to the switching on and off caused by the stat maintaining temperature?

Depends on the thermostat. An on off variety will lower the life span a lot. It will be turning the CHE on and off causing lots of wear and tear. A proportial stat will lower the life a little bit not enough to really matter.
I use a few CHE controlled by a VE200 dimming and it works great.
