This unit puts out steam as well as my previous Steamist $1,800 unit. The big issue was the wiring. The instructions are indecipherable. The review above showing the connections is correct: Wire one phase to terminals L and L, the other phase to terminals N and N [for 220v].The control is not as sophisticated as the Steamist:1. Instructions say to mount the control outside the steam room and place the separate temp sensor inside the room. Steamist has all in one control mounted inside the steam room so you can easily adjust time and temp.2. You cannot set the time. It runs 60 minutes unless you manually shut off first.3. As mentioned in other reviews, the temp display is Celsius not Farenheight. Cannot be changed.4. The unit does not auto flush to remove buildup in the steam container. A drain must be opened monthly manually when the unit has just turned off and is in the cooling mode.
