Central heating room control
Is there no way to control individual room heating with central heating? I have a two-story home in temperate ocean-influenced So Cal climate. I am about to face a complete renovation on my home, and was just wondering if there was any way to prevent the downstairs from being heated when I'm upstairs, or if there is a way to control heating room by room with central heating.
It seems like such a waste to blow heat through the whole house all at once when you're only occupying say, the kitchen and living room.
