Thanks Etienne. That is exactly the one I have. I am using an extension
cord (not much choice), but a real heavy duty one (DH is a carpenter so
we have heavy ones). I did not leave it on long last night when
testing. I will turn it on today and leave it to test. I may have to
forgo the thermostat automation and just turn it on in the afternoon to
heat the plug trays and leave it on over night. I was originally
concerned about "cooking" the plugs, but don't think that will be a problem.
Reassuring to know they work for you. I have them strung 6 to 7 inches
apart. How close are yours?
