Combining Slab radiant w/ HWBboard

in THE MAIN WALL
I am in the process of planning a mudroom addition to our home. Our house currently has hot water baseboard for heat. My question is can I add radiant heat to my mudroom slab using my existing boiler that supplies the HWBB? I know enough now to understand that supply temps. for HWBB are higher than radiant. How would I go about including the radiant loop into my existing system? The mudroom is Approximately 100 SqFt. and will be a tiled floor over slab. Also what tubing would be best for this?
Thanks for any help.

    A simple way to do it

    You'll need a pump and a mixing valve. Cut two tees into the baseboard loop that serves that area, very close together. The first (supply) tee will feed the hot port on the mixer. The second tee will go to a tee that connects to the cold port on the mixer and to the return from the floor. The mix port connects to the circulator inlet. The circulator outlet feeds the floor tubing.

    Wire this pump to run at the same time as this zone is running. Nothing else is needed, but to dial in the water temp to your comfort.
