I have one t-stat for furnace . Its upstairs in a two story house. Is it possible to install an additional t-stat downstairs and have a toggle or swithing station that lets me choose which t-stat to use? If I use my wood stove upstairs , then the t-stat never clicks on , thus the bottom floor gets no heat. I know its done with electricity and audio , why not heating circuits?

Yes you could do it but then the heat will still go into the hot areas anyway defeating your purpose. Why not turn the fan to ON and let it circulate the hot air to the rest of the house. The best solution would be to install a 2 zone control panel on the heater. Then you could have air directed and controlled to whatever floor calls for heat. One zone would be first floor and the other zone would be second. You would have to find the main plenum that services the floor without a t'stat and go from there.

Can I join in?

My question is the same but I was wondering if I could install a master register, cutting down the supply to the upper half of my home? I saw a motorized vent on "This Old House" shutting off supply to a second duct system when the T Stat was "satisfied". I feel that if you go around closing vents, it's just wasting force to those ducts... Am I wrong?

Side note: I also saw a vent zone system for forced air that blew up bags in ducts not in use forcing air to those in use... Kind of like a sprinkler system... It was hot (pardon the pun).

Here is a basic layout of my house.

That is what I was proposing to T barn. The motorized supply vent will switch to the second level but you still need 2 t'stats and a zone control. Closing vents unbalances the system

Brad, please do not add your question to another post. Resubmit your question as new. That way, we know what question to answer. Thanks for your understanding, Brian
