in Thermostats and Controls
Okay,

I have a new contractor that I am working with and he is in the geo thermal heating buisness. I am doing the connections for the water to air and water to water systems. Customers want to connect old systems with new as a back up and to be able to use if the power goes out because they have the old heat tied into the excisting back up generoator.

What does anyone think.

What would you sugest and how would you pipe it. And what controls would you use.

    Parallel

    Pipe in parallel.



    Put valves on both sides of everything.



    I would keep it simple, and make the valves manual. Like the change over from heating to cooling.



    Or if you want to get exotic, you can use motorized gear, but I have found when you really need that motorized valve to open like during a power failure, it won't.



    Or why not just tie the new stuff into the back up generator?
