Keep in mind, Lucky, these two heaters are 240V and not simple, plug-in, 120V ones. They are hard-wired. I had to have everything wired from the two greenhouses back into the house electrical panel, and two new 220V breakers put in. This was not a "cheap" endeavor. I felt it was necessary to insure I have (more than) adequate heat in those greenhouses. Those two heaters came from Northern Tool & Equipment and they are Model PH-960, ProFusion heaters.
