I am remodling the second floor of a Levitt house on Long Island. Currently I have baseboard throughout the original radiant floor heating was abandoned due to leaks many many years ago. The entire second floor will be remodled. Can I install radiant floor heating on the second floor while retaining the baseboard on the first floor. I have a two zone system already. I am wondering if each system requires water of a different temperature. I cannot redo the fist level as the home is built on a slab.
We have been considering forced hot air heated by hot water. The house will have central AC.

WE would rather have no baseboards in the new addition for multiple asthetic reasons. Wall space, bent and always busted looking covers.
Thanks.
