Growing up, one of my good friends in high school lived in a fairly nice 1920s era home that had this. I never really saw it in action. Is it a big energy waster or is it not too unreasonable?
But surely the central vac was quite new.
My parents installed it around 6 years ago. I think they like it, but I don't know if they really know that not all vacuums are created equal.
You must be thinking of "central heating".![]()
