Ok, so I have 2 - 2000 watt ceiling mount heaters with blowers in them. Each are feed from there own circuit from the panel. They both have their own t-stat terminal points to hookup too in the heater housing that is for across the line hookups that does not cut power to the whole unit, as the blower keeps running until the unit cools down when the t-stat shuts off. So my question is what is the best way to hookup one t-stat to control both units. I know I could probably just put in a 240 volt coil relay that is picked up by the t-stat to turn the on both heaters, but I wondering what other options / opinions you may have. One other thing I was wondering, does any manufacturer make a t-stat that has two sets of contacts for across the line heaters that is capable of handling a total of 4000 watts ( remember that each heater has its own feed )
Thanks for any replies

There is no line voltage t'stat. That I am aware of, to carry 4000 watts.

The relay method will work the best.
