    Packaged Rooftop versus Hydronic Costs

    In my market place (Pittsburgh,PA), it seems that packaged rooftop units are the only thing being installed. A new building with hydronics would probably cause the Mason Dixon line to split. I would like to see if anyone has seen a study that shows the operating cost comparison of a packaged rooftop unit and a hydronic system. Thanks in advance.

    Something to think about

    a rooftop unit is located outside the building envelope, so it loses a lot more of the heat it generates than a hydronic system does.

    unitary rooftop oversold

    Unitary rooftops are the most oversold system. Everything to be serviced is in one package out there. And a packaged unit is cheaper to install than built up.

    Of course a roof lasts longer if nobody is on it dropping their tools.

    roof damage

    the worst thing about rooftop units are the cabinet screws which never get put back in, and lie on the roof waiting for a step to push them ithrough the roof membrane!--nbc
